562 an operator in the case that analysis on the node yields the relevant
563 operator - so prefer it instead.

705 2017-11-09 Pascal Obry <obry@adacore.com>
707 * libgnarl/s-taprop__mingw.adb: On Windows, initialize the thead handle
708 only for foreign threads. We initialize the thread handle only if not
709 yet initialized. This happens in Enter_Task for foreign threads only.
710 But for native threads (Ada tasking) we do want to keep the real
711 handle (from Create_Task) to be able to free the corresponding
712 resources in Finalize_TCB (CloseHandle).

726 (Make_DT): Declare constant the Interface_Table object associated with
727 an statically built dispatch table. For this purpose the Offset_To_Top
728 value of each interface is computed using the dummy object.
729 * exp_ch3.adb (Build_Init_Procedure): Do not generate code initializing
730 the Offset_To_Top field of secondary dispatch tables when the dispatch
731 table is statically built.

743 2017-11-09 Jerome Lambourg <lambourg@adacore.com>

748 * libgnarl/s-osinte__qnx.ads: Add some missing bindings to pthread.
749 * libgnarl/s-taprop__qnx.adb: New, derived from s-taprop__posix.adb. This brings
750 in particular a workaround with locks priority ceiling where a higher
751 priority task is allowed to lock a lower ceiling priority lock. This
752 also fixes the scheduling of FIFO tasks when the priority of a task is
754 * libgnat/system-qnx-aarch64.ads: Fix priority ranges.
756 2017-11-09 Yannick Moy <moy@adacore.com>
758 * erroutc.adb (Output_Error_Msgs): Justify CodePeer false positive
760 * gnatbind.adb (Scan_Bind_Arg): Simplify test to remove always true
762 * namet.adb (Copy_One_Character): Add assumption for static analysis,
763 as knowledge that Hex(2) is in the range 0..255 is too complex for
765 (Finalize): Add assumption for static analysis, as the fact that there
766 are symbols in the table depends on a global invariant at this point in
768 * set_targ.adb (Check_Spaces): Justify CodePeer false positive message.
769 * stylesw.adb (Save_Style_Check_Options): Rewrite to avoid test always
772 2017-11-09 Javier Miranda <miranda@adacore.com>

812 * exp_util.adb (Find_Interface_Tag): Default initialize AI_Tag.
813 * freeze.adb (Check_Component_Storage_Order): Default initialize
814 Comp_Byte_Aligned rather than silencing messages with pragma
815 Warnings(Off), which does not work for CodePeer initialization
816 messages, and given that here the possible read of an unitialized value
817 depends on a proper use of parameters by the caller.
818 * inline.adb (Expand_Inlined_Call): Default initialize Lab_Decl, Targ.
819 * sem_ch12.adb (Build_Operator_Wrapper): Default initialize Expr.
820 * sem_ch3.adb (Build_Derived_Array_Type): Default initialize

824 (Analyze_Case_Expression): Rescope checking block within branch where
825 Others_Present is set by the call to Check_Choices.
826 * sem_ch5.adb (Analyze_Assignment): Default initialize
828 * sem_ch6.adb (Analyze_Function_Return): Default initialize Obj_Decl,
829 and restructure code to defend against previous errors, so that, in
830 that case, control does not flow to the elsif condition which read an
831 uninitialized Obj_Decl.
832 * sem_ch9.adb (Analyze_Requeue): Default initialize Synch_Type.
833 (Check_Interfaces): Default initialize Full_T_Ifaces and Priv_T_Ifaces,
834 which seem to be left uninitialized and possibly read in some cases.
835 * sem_dim.adb (Analyze_Aspect_Dimension_System): Retype Position more
836 precisely. This requires to exchange the test for exiting in case of
837 too many positions and the increment to Position, inside the loop.
838 * sem_eval.adb (Eval_Concatenation): Default initialize Folded_Val,
839 which cannot be read uninitialized, but the reasons for that are quite
841 * sem_intr.adb (Check_Intrinsic_Call): Default initialize Rtyp.
842 * sem_prag.adb (Collect_Subprogram_Inputs_Outputs): Default initialize
844 * sem_res.adb (Make_Call_Into_Operator): Default initialize Opnd_Type,
845 and test for presence of non-null Opnd_Type before testing its scope,
846 in a test which would read its value uninitialized, and is very rarely
847 exercized (it depends on the presence of an extension of System).
848 * sem_spark.ads: Update comment to fix name of main analysis procedure.
849 * sem_warn.adb (Warn_On_Known_Condition): Default initialize
851 * set_targ.adb (FailN): Mark procedure with No_Return.

859 * exp_ch11.adb (Possible_Local_Raise): Do not issue the warning for

879 when processing generic instances.
881 2017-11-09 Bob Duff <duff@adacore.com>
883 * namet.ads, namet.adb (Valid_Name_Id): New subtype that excludes
884 Error_Name and No_Name. Use this (versus Name_Id) to indicate which
885 objects can have those special values. Valid_Name_Id could usefully be
886 used all over the compiler front end, but that's too much trouble for
887 now. If we did that, we might want to rename:
888 Name_Id --> Optional_Name_Id, Valid_Name_Id --> Name_Id.
889 For parameters of type Valid_Name_Id, remove some redundant tests,
890 including the ones found by CodePeer. Use Is_Valid_Name instead of
891 membership test when appropriate.
892 (Error_Name_Or_No_Name): Delete this; it's no longer needed.
893 * sem_ch2.adb (Analyze_Identifier): Use "not Is_Valid_Name" instead of
894 "in Error_Name_Or_No_Name".

956 * sem_res.adb (Resolve): If expression is an entity whose type has
957 implicit dereference, generate reference to it, because no reference is
958 generated for an overloaded entity during analysis, given that its
959 identity may not be known.
961 2017-11-09 Javier Miranda <miranda@adacore.com>
963 * exp_disp.adb (Expand_Interface_Thunk): Replace substraction of

970 Set_Static_Offset_To_Top passing a negative offet-to-top value;
971 initialize also the offset-to-top field with a negative offset.
972 * libgnat/a-tags.adb (Base_Address): Displace the pointer by means of
973 an addition since the offset-to-top field is now a negative value.
974 (Displace): Displace the pointer to the object means of a substraction
975 since it is now a negative value.

2320 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Add self-checking

2324 as for the other Is_B-I-P... functions.

2332 internally-generated call.

2337 implies >= Ada 2005.

2367 a freeze node for the instance of the parent if it appears in the same
2368 scope and is not frozen yet.

2375 2017-10-09 Bob Duff <duff@adacore.com>
2377 * exp_ch3.adb (Build_Assignment): Parameter name N was somewhat
2378 confusing. Same for N_Loc. Remove assumption that b-i-p implies
2379 limited. This is for the case of a function call that occurs as the
2380 default for a record component.
2381 (Expand_N_Object_Declaration): Deal with the case where expansion has
2382 created an object declaration initialized with something like

2452 (Is_Build_In_Place_Result_Type): New function to accompany
2453 Is_Build_In_Place_Function and Is_Build_In_Place_Function_Call, because
2454 sometimes we just have the type on our hands, not the function. For
2455 now, does the same thing as the old version, so build-in-place is

2473 an unchecked conversion. Add assertions.

2502 (Is_Secondary_Stack_BIP_Func_Call): Don't check if Nkind (Selector_Name

3495 (Iterate_Call_Parameters): New
3496 procedure to iterate on formals and actuals at the same time.
3497 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
3498 Set SPARK_Mode from spec when set, for analysis
3499 of instance. Restore after analysis of instance.
3500 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
3501 set, for analysis of body instance. Restored automatically at
3502 the end of the subprogram.

3510 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
3511 (New_Copy_Tree): ...there. Reset the hash tables only if they
3512 were used in the previous invocation.
3513 * s-htable.adb: Fix typo.
3515 2017-09-08 Bob Duff <duff@adacore.com>
3517 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
3519 2017-09-08 Arnaud Charlet <charlet@adacore.com>

3543 * sem_ch12.adb: Minor typo fixes and reformatting.
3545 2017-09-08 Yannick Moy <moy@adacore.com>
3547 * sem_aggr.adb (Resolve_Record_Aggregate):
3548 Rewrite bounds of aggregate subexpressions which may depend on
3549 discriminants of the enclosing aggregate.
3551 2017-09-08 Yannick Moy <moy@adacore.com>
3553 * sem_ch5.adb: Prevent assertion failure on illegal code.
3555 2017-09-08 Yannick Moy <moy@adacore.com>

3562 * exp_aggr.adb: Add with & use clause for Urealp.
3563 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
3564 elementary types instead of just discrete types.
3565 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
3566 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
3567 Be prepared for the FP zero value in the memset case. Add small
3570 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3572 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
3575 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
3577 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
3578 of New_Copy because the latter leaves the syntactic structure of
3579 the tree inconsistent (a child is accessible through two parents)
3580 and prevents proper replication of itypes by subsequent calls
3582 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
3583 New_Copy because the latter leaves the syntactic structure of the
3584 tree inconsistent (a child is accessible through two parents)
3585 and prevents proper replication of itypes by subsequent calls
3587 * sem_util.adb (In_Subtree): New routine.

3594 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
3595 for aspect Default_Value is a static scalar value, but it does
3596 not freeze the type. Yhis allows for subsequent representation
3597 clauses for the type.
3599 2017-09-08 Javier Miranda <miranda@adacore.com>
3601 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
3602 not add entries into the undefined reference table when we are
3603 compiling with errors ignored.
3605 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3607 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
3608 check if the instance is within an enclosing instance body. The
3609 formal package was legal in the enclosing generic, and is
3610 legal in the enclosing instantiation. This optimisation may be
3611 applicable elsewhere, and it also removes spurious errors that
3612 may arise with on-the-fly processing of instantiations that
3613 contain Inline_Always subprograms.
3615 2017-09-08 Vincent Celier <celier@adacore.com>
3617 * gnatcmd.adb: Disregard empty argument of GNAT driver.
3619 2017-09-08 Justin Squirek <squirek@adacore.com>
3621 * checks.adb (Insert_Valid_Check): Manually decorate
3622 the generated temporary for range valdity checks.

3633 new procedure to handle underscores.
3635 2017-09-08 Javier Miranda <miranda@adacore.com>
3637 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
3638 divisions with fixed point results to avoid generating twice
3639 the runtime check on divide by zero.
3640 * checks.adb (Apply_Divide_Checks): Ensure that operands are
3641 not evaluated twice (once for their runtime checks and once for
3642 their regular computation).
3644 2017-09-08 Yannick Moy <moy@adacore.com>
3646 * sem_prag.adb (Analyze_Part_Of): Add missing
3647 return statements after issuing errors. Add detection of
3648 out-of-order item and single concurrent type.

3778 when the actual is a construct that involves a dereference of an
3779 expression that includes a formal of the enclosing subprogram,
3780 In such cases, the accessibility level of the actual is that of
3781 the corresponding formal, which is passed in as an additional
3782 actual in the outer call.

3792 exceptions instead of crashes. Check for absurdly long strings
3793 and empty strings. Empty strings cause trouble because they can
3794 have super-null ranges (e.g. 100..10), which causes Ext_Copy to
3795 be empty, which causes an array index out of bounds.

3857 under -gnat2020 flag, given that it is a future feature of
3859 * sem_aggr.adb (Resolve_Iterated_Component_Association): Mark
3860 defining identifier as referenced to prevent spurious warnings:
3861 corresponding loop is expanded into one or more loops whose
3862 variable has the same name, and the expression uses those names
3863 and not the original one.

3924 statements, use local variable and remove unnecessary processing.
3926 2017-09-08 Javier Miranda <miranda@adacore.com>
3928 * exp_ch6.ads (Make_Build_In_Place_Iface_Call_In_Allocator): New

3931 (Make_Build_In_Place_Iface_Call_In_Object_Declaration): New
3933 (Unqual_BIP_Iface_Function_Call): New subprogram.
3934 * exp_ch6.adb (Replace_Renaming_Declaration_Id): New
3935 subprogram containing code that was previously inside
3936 Make_Build_In_Place_Call_In_Object_Declaration since it is also
3937 required for one of the new subprograms.
3939 Invoke Make_Build_In_Place_Iface_Call_In_Anonymous_Context
3940 (Expand_N_Extended_Return_Statement): Extend the
3941 cases covered by an assertion on expected BIP object
3943 (Make_Build_In_Place_Call_In_Assignment):
3944 Removing unused code; found working on this ticket.
3945 (Make_Build_In_Place_Call_In_Object_Declaration): Move the code
3946 that replaces the internal name of the renaming declaration
3947 into the new subprogram Replace_Renaming_Declaration_Id.

3972 * exp_disp.adb (Expand_Interface_Conversion): Fix handling of
3973 access to interface types. Remove also the accessibility check.
3975 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3977 * sem_ch6.adb (Freeze_Expr_Types): Really freeze
3978 all the types that are referenced by the expression.
3979 (Analyze_Expression_Function): Call Freeze_Expr_Types for
3980 a completion instead of manually freezing the type of the
3982 (Analyze_Subprogram_Body_Helper): Do not call Freeze_Expr_Types here.
3984 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3986 * exp_prag.adb (Replace_Discriminals_Of_Protected_Op):
3987 New procedure, auxiliary to Expand_Pragma_Check, to handle
3988 references to the discriminants of a protected type within a
3989 precondition of a protected operation. This is needed because
3990 the original precondition has been analyzed in the context of
3991 the protected declaration, but in the body of the operation
3992 references to the discriminants have been replaved by references
3993 to the discriminants of the target object, and these references
3994 are only created when expanding the protected body.
3996 2017-09-08 Yannick Moy <moy@adacore.com>
3998 * sem_prag.adb (Analyze_Pragma): Issue more precise error messages on
4001 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4003 * exp_attr.adb (Build_Record_VS_Func): If the record is an
4004 unchecked union, do not emit checks for its (non-existent)
4005 discriminants, or for variant parts that depend on them.
4007 2017-09-08 Justin Squirek <squirek@adacore.com>
4009 * sem_ch4.adb (Find_Equality_Types.Try_One_Interp,
4010 Find_Comparison_Type.Try_One_Interp): Add check for generic
4013 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4015 * sem_ch3.adb, layout.adb, layout.ads, exp_attr.adb, debug.adb,
4016 exp_pakd.adb, sem_prag.adb, gnat1drv.adb, targparm.adb, targparm.ads,
4017 repinfo.adb, exp_ch6.adb, exp_aggr.adb, sem_eval.adb, sem_ch13.adb,
4018 exp_ch3.adb: Remove references to Frontend_Layout_On_Target and
4019 remaining references to AAMP_On_Target.
4021 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4023 * style.adb: Fix typo.
4025 2017-09-08 Javier Miranda <miranda@adacore.com>
4027 * einfo.adb (Underlying_Type): Add missing support for class-wide
4028 types that come from the limited view.
4029 * exp_attr.adb (Attribute_Address): Check class-wide type
4030 interfaces using the underlying type to handle limited-withed
4032 (Attribute_Tag): Check class-wide type interfaces using
4033 the underlying type to handle limited-withed types.
4035 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4037 * exp_ch5.adb (Expand_Predicated_Loop): Handle properly a loop
4038 over a subtype of a type with a static predicate, taking into
4039 account the predicate function of the parent type and the bounds
4040 given in the loop specification.
4041 * sem_ch3.adb (Inherit_Predicate_Flags): For qn Itype created for
4042 a loop specification that is a subtype indication whose type mark
4043 is a type with a static predicate, inherit predicate function,
4044 used to build case statement for rewritten loop.
4046 2017-09-08 Justin Squirek <squirek@adacore.com>
4048 * lib-load.adb: Modify printing of error message to exclude file
4051 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4053 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode):
4054 don't inline subprograms declared in both visible and private
4056 (In_Package_Spec): previously In_Package_Visible_Spec; now
4057 detects subprograms declared both in visible and private parts
4060 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4062 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
4063 the type is an anonymous array in an object declaration, whose
4064 component type has an invariant, use the object declaration
4065 as the insertion point for the invariant procedure, given that
4066 there is no explicit type declaration for an anonymous array type.
4068 2017-09-08 Bob Duff <duff@adacore.com>
4070 * a-cbprqu.ads, a-cbdlli.adb: Suppress warnings.

4074 * a-strfix.adb (Trim): Compute Low and High only if needed.
4076 2017-09-08 Justin Squirek <squirek@adacore.com>

4079 source file is missing.
4081 2017-09-08 Bob Duff <duff@adacore.com>
4084 * a-textio.adb, a-witeio.adb, a-ztexio.adb (Set_WCEM): Use
4085 Default_WCEM by default (i.e. if the encoding is not specified
4086 by the Form string).
4088 2017-09-08 Bob Duff <duff@adacore.com>
4090 * s-trasym.ads (Hexa_Traceback): If
4091 Suppress_Hex is True, print "..." instead of a hexadecimal
4093 * s-trasym.adb: Ignore No_Hex in this version.
4096 2017-09-08 Bob Duff <duff@adacore.com>
4098 * debug.adb: Minor reformatting.
4100 2017-09-08 Bob Duff <duff@adacore.com>
4102 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the
4103 code so it doesn't trigger an "uninit var" warning.
4105 2017-09-08 Nicolas Roche <roche@adacore.com>
4107 * s-hibaen.ads: Remove obsolete file.
4109 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4111 * a-locale.ads: Add comment explaining the state of this package.
4113 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4115 * sem_util.adb (Is_CCT_Instance): Allow calls in the context
4117 * sem_prag.ads, sem_prag.adb (Find_Related_Declaration_Or_Body):
4118 allow calls in the context of package spec (for pragma
4119 Initializes) and bodies (for pragma Refined_State).
4121 2017-09-08 Bob Duff <duff@adacore.com>
4123 * checks.adb (Insert_Valid_Check): Copy the Do_Range_Check flag to the
4126 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4128 * debug.adb (dA): Adjust comment.
4129 * gnat1drv.adb (Gnat1drv): Likewise.
4130 * opt.ads (List_Representation_Info_Extended): New variable.
4131 * repinfo.adb (List_Record_Info): Split implementation into...
4132 (Compute_Max_Length): ...this. Recurse on records if requested.
4133 (List_Record_Layout): Likewise.
4134 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
4135 statement, accept '0' and set List_Representation_Info_Extended
4137 * usage.adb (Usage): Document new -gnatRe variant.
4139 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4141 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
4142 Do not save the given entity in the global variable Default_Pool
4143 if the pragma appears within a generic unit.
4145 2017-09-08 Bob Duff <duff@adacore.com>
4147 * errout.adb (Delete_Warning): Do not
4148 decrement Warnings_Treated_As_Errors. This is called before
4149 Warnings_Treated_As_Errors has been incremented to account for
4150 this warning. Decrementing it here can lead to negative values
4151 of Warnings_Treated_As_Errors, raising Constraint_Error in
4152 checks-on builds, and causing the compiler to return an error
4153 code in checks-off builds.
4155 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4157 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
4158 entities of named concurrent types as Ref_Id and not of anonymous
4159 concurrent objects (because callers already know when a conversion
4160 is necessary and can easily do it); also, do not expect protected
4161 types or protected objects as Context_Id (because no flow-related
4162 SPARK pragmas are attached there); reflect these changes in a
4163 more precise comment.
4165 2017-09-08 Olivier Hainque <hainque@adacore.com>
4167 * g-altive.ads: Add documentation.
4169 2017-09-08 Bob Duff <duff@adacore.com>
4171 * sem_util.ads, debug.adb: Minor comment fix.
4172 * erroutc.ads: Comment fix.
4174 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4176 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
4177 for compatibility of component types of formal and actual in an
4178 instantiation of a child unit, when the component type of the
4179 formal is itself a formal of an enclosing generic.
4181 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4183 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
4184 sem_prag.adb to make it available for GNATprove; for concurrent
4185 types replace custom scope climbing with Scope_Same_Or_Within; for
4186 single concurrent objects add scope climbing (with Scope_Within),
4187 which was not there (that's the primary semantic change of this
4188 commit); also, when comparing a single concurrent object with
4189 its corresponding concurrent type rely on equality of types,
4190 not of objects (because that's simpler to code).
4191 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
4192 (Analyze_Global_Item): adjust special-casing of references to the
4193 current instance of a concurrent unit in the Global contracts
4194 of task types and single tasks objects; similar for references
4195 in the protected operations and entries of protected types and
4196 single protected objects (in all these cases the current instance
4197 behaves as an implicit parameter and must not be mentioned in
4198 the Global contract).
4200 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4202 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
4203 function calls returning a record within a subprogram call,
4206 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4208 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
4209 name that designates the current instance of a child unit in its
4210 own body and appears as the prefix of a reference to an entity
4211 local to the child unit.
4212 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
4215 2017-09-08 Yannick Moy <moy@adacore.com>
4217 * sem_res.adb (Resolve_Equality_Op): Do not warn on comparisons that
4220 2017-09-08 Tristan Gingold <gingold@adacore.com>
4222 * sem_warn.adb (Check_Unused_Withs): Remove test that disabled
4223 warnings on internal units in configurable run time mode.
4225 2017-09-08 Bob Duff <duff@adacore.com>
4227 * sem_ch3.adb (Build_Derived_Private_Type): Inherit
4228 representation items from interfaces that the derived type
4229 implements, not just from the parent type.
4230 * sem_util.ads, sem_util.adb (Abstract_Interface_List): Change
4231 this to return an empty list when there are no interfaces.
4232 * einfo.ads, sem_ch13.adb: Minor comment fixes.
4233 * sem_attr.adb: Minor comment fix.
4235 2017-09-08 Doug Rupp <rupp@adacore.com>

4240 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4242 * exp_ch4.adb (Expand_N_Allocator): Generate a
4243 call to Allocate_Any_Controlled when the allocation does not
4244 require any initialization.
4246 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4248 * sem_util.adb (Copy_Node_With_Replacement):
4249 Update the Renamed_Object field of a replicated object renaming
4252 2017-09-08 Patrick Bernardi <bernardi@adacore.com>
4254 * exp_ch9.adb (Is_Pure_Barrier): Allow type
4255 conversions and components of objects. Simplified the detection
4256 of the Count attribute by identifying the corresponding run-time
4259 2017-09-08 Yannick Moy <moy@adacore.com>
4261 * exp_ch9.adb, exp_disp.adb, repinfo.adb, sem_ch12.adb, sem_dim.adb,
4262 sem_type.adb, sinfo.ads: Minor reformatting.
4264 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4266 * freeze.adb (Has_Incomplete_Compoent): New predicate, subsidiary
4267 of Freeze_Profile, used to inhibit the freezing of the profile
4268 of an expression function declared within a nested package, when
4269 some type in the profile depends on a private type declared in
4270 an enclosing package.
4272 2017-09-08 Bob Duff <duff@adacore.com>
4274 * gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in
4275 the subunit case. It's still OK to set it in the "missing subunits"
4276 case, because that won't cause the obsolete .ali files that cause
4279 2017-09-08 Bob Duff <duff@adacore.com>
4281 * sinput-l.adb: Remove unused "with Unchecked_Conversion;". It's
4282 unclear why this didn't cause a warning.
4283 * a-uncdea.ads, a-unccon.ads: Add "Ada." to names in the
4284 pragmas. It's unclear why this didn't cause an error.
4286 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4288 * exp_spark.adb (Expand_SPARK_N_Object_Renaming_Declaration):
4290 (Expand_SPARK_Potential_Renaming): Code clean up.
4291 * sem_prag.adb (Analyze_Initialization_Item): Add a guard in case
4292 the item does not have a proper entity.
4293 (Analyze_Input_Item): Add a guard in case the item does not have a

4310 * repinfo.adb (List_Record_Info): During first loop,
4311 do not override the normalized position and first bit
4312 if they have already been set. Move fallback code
4313 for the packed case to the case where it belongs.
4314 * sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order):
4315 Also adjust the normalized position of components.
4316 (Adjust_Record_For_Reverse_Bit_Order_Ada_95): Likewise.
4318 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4320 * exp_disp.adb (Make_DT, Set_All_DT_Position): Handle properly
4321 the placement of a primitive operation O that renames an operation
4322 R declared in an inner package, and which is thus not a primitive
4323 of the dispatching type of O. In this case O is a new primitive
4324 and does not inherit its dispatch table position from R (which

4329 * sem_dim.adb (Analyze_Dimension_If_Expression,
4330 Analyze_Dimension_Case_Expression): new subprograms to verify
4331 the dimensional correctness of Ada2012 conditional expressions,
4332 and set properly the dimensions of the construct.
4333 * sem_res.adb (Resolve_If_Expression, Resolve_Case_Expression)):
4334 call Analyze_Dimension.
4336 2017-09-08 Ed Schonberg <schonberg@adacore.com>

4339 loop on an interface declared as a private extension of another
4340 synchronized interface.
4342 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4344 * sem_ch12.adb (Check_Generic_Parent): New procedure within
4345 Analyze_Associations, to handle actual packages that depend on
4346 previous instances. If a package IAP that is an instantiation is
4347 used as an actual in a subsequent instantiation SI in the same
4348 scope, and IAP has a body, IAP must be frozen before SI. If
4349 the generic parent of IAP is itself declared in a previous
4350 instantiation in the same scope, that instantiation must also
4351 be frozen before SI.
4352 (Install_Body): Prevent double insertion of freeze node for
4355 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4357 * sem_prag.adb (Resolve_State): Update the
4358 comment on documentation. Generate a reference to the state once
4359 resolution takes place.
4361 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4363 * sem_ch13.adb (Analyze_Aspect_Specifications, case
4364 Linker_Section): If the aspect applies to an object declaration
4365 with explicit initialization, do not delay the freezing of the
4366 object, to prevent access-before-elaboration in the generated
4367 initialization code.
4369 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4371 * a-wtdeio.adb (Put, all versions): Use Long_Long_Integer
4372 (Integer_Value (Item)) when the size of the fixed decimal type
4373 is larger than Integer.
4375 2017-09-07 Eric Botcazou <ebotcazou@adacore.com>
4378 * gcc-interface/decl.c (copy_and_substitute_in_layout): Put the fields
4379 in order of increasing position in more cases.
4381 2017-09-07 Yannick Moy <moy@adacore.com>
4383 * a-exetim-mingw.ads: Add contract Global=>null
4384 on all operations that are modeled as having no read or write
4385 of global variables in SPARK.
4387 2017-09-07 Raphael Amiard <amiard@adacore.com>
4389 * a-chtgop.adb, a-chtgop.ads (Generic_Iteration_With_Position): Added

4401 allow disabling the generation of implicit pragma Elaborate_All
4404 2017-09-07 Javier Miranda <miranda@adacore.com>
4406 * exp_disp.adb (Make_Tags): Avoid suffix counter
4407 in the external name of the elaboration flag. Required to fix
4408 the regressions introduced by the initial version of this patch.
4410 2017-09-07 Bob Duff <duff@adacore.com>
4412 * sem_ch6.adb (Analyze_Function_Return): Do not
4413 insert an explicit conversion to force the displacement of the
4414 "this" pointer to reference the secondary dispatch table in the
4415 case where the return statement is returning a raise expression,
4416 as in "return raise ...".

4454 explicit dereference, as required by 3.7.2 (2) and as is done
4455 with most other attributes whose prefix is an access value.
4457 2017-09-07 Bob Duff <duff@adacore.com>

4579 initialization of its dispatch tables. (Init_Secondary_Tags):

4581 Ada.Tags.Set_Dynamic_Offset_To_Top since it has a new formal;

4583 because the type of one of its formals has been changed.
4584 * a-tags.ads, a-tags.adb (Register_Interface_Offset): Profile
4585 modified. Instead of receiving a pointer to an object this
4586 routine receives now a primary tag.
4587 (Set_Dyanic_Offset_To_Top): Profile modified. This routine receives an
4588 additional formal: the tag of the primary dispatch table.
4589 * exp_disp.ads (Elab_Flag_Needed): New subprogram.
4590 * exp_disp.adb (Elab_Flag_Needed): New subprogram.

4622 is now consulted not only for abstract states and variables,
4623 but for all kinds of items.
4624 (Collect_Subprogram_Inputs_Outputs): Do not process formal
4625 generic parameters, because unlike ordinary formal parameters,
4626 generic formals only act as input/ outputs if they are explicitly
4627 mentioned in a Global contract.
4629 2017-09-07 Yannick Moy <moy@adacore.com>
4631 * ghost.adb (Check_Ghost_Context): Do not err on ghost code inside

4644 derived recor type, copy the dikensions if any of each component
4645 of the parent record to the corresponding component declarations
4646 of the derived record. These expressions are used among other

4692 Make_Build_In_Place_Call_In_Anonymous_Context): Do not use the
4693 secondary stack for all functions that return limited tagged
4694 types -- just do it for dispatching calls. Misc cleanup.
4695 * sem_util.ads, sem_util.adb (Unqual_Conv): New function to
4696 remove qualifications and type conversions. Fix various bugs
4697 where only a single level of qualification or conversion was
4698 removed, so e.g. "T1'(T2'(X))" would incorrectly return "T2'(X)"
4700 * checks.adb, exp_util.ads, exp_util.adb, sem_res.adb: Misc related
4703 2017-09-07 Ed Schonberg <schonberg@adacore.com>

4708 * sem_ch13.adb (Build_Predicate_Functions): Indicate that entity
4709 of body is a predicate function as well.
4710 (Resolve_Aspect_Expressions, Resolve_Name): For a component
4711 association, only the expression needs resolution, not the name.
4712 (Resolve_Aspect_Expressions, case Predicates): Construct and
4713 analyze the predicate function declaration in the scope of the
4714 type, before making the type and its discriminants visible.

4755 2017-09-06 Bob Duff <duff@adacore.com>
4757 * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
4758 requested. Previously, the -do switch meant "run Elab_New and
4759 Elab_Old and use the order chosen by Elab_Old, possibly with
4760 debugging printouts comparing the two orders." Now it means
4761 "do not run Elab_New." This is of use if there are bugs that
4762 cause Elab_New to crash.
4763 (Elab_Position, Num_Chosen): Change type to Nat, to avoid various

4780 <Sized_Component_Total_Round_RM_Size>: New local variable to
4781 accumulate the rounded RM_Size of components. Update it for

4784 the error about packing. Swap condition for clarity's sake.

4808 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
4809 entity of a mutable type and the right-hand side is a conditional
4810 expression, resolve the alternatives of the conditional using
4811 the base type of the target entity, because the alternatives

4813 the alternatives are aggregates.
4815 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4817 * checks.adb (Apply_Predicate_Check): If the expression is an
4818 aggregate that is the RHS of an assignment, apply the check to
4819 the LHS after the assignment, rather than to the aggregate. This
4820 is more efficient than creating a temporary for the aggregate,
4821 and prevents back-end crashes when the aggregate includes a
4822 dynamic "others' association.

4844 * errout.adb (Error_Msg): Separate the
4845 treatment for warning vs. style messages in inlinings and
4846 instantiations. Prevents blowups on calls to Warn_Insertion for
4847 style messages, which should not be called in that case because
4848 Warning_Msg_Char is not set.

4856 component case, a pragma applied individually to a component, and

4876 that is a proper body corresponding to a stub, we defer the
4877 adjustment of the sloc until after the correct adjustment has
4878 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore

4985 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
4986 we include the proper header. Otherwise, we just declare the necessary
4987 things from the capabilities library. This is so we can build on
4988 machines without that library, while still enabling that library.
4989 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
4990 simply return 0 if the library is not present, or not included

5012 uses of 'Image and related attributes as having side effects in
5013 order to avoid replicating such uses.
5014 * pprint.ads (Expression_Image) Add new generic formal flag
5015 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
5016 (eventually) override the default.
5017 * pprint.adb (Expression_Image) If the new flag is set, then
5018 suppress the ".all" suffix when displaying a dereference whose
5019 prefix is a use of a value-capturing compiler temp of the sort
5020 generated by Expr_Util.Remove_Side_Effects .

5036 so that applies to any entity.
5038 2017-09-06 Yannick Moy <moy@adacore.com>
5040 * sem_ch3.adb (Derived_Type_Declaration): Use
5041 Incomplete_Or_Partial_View rather than local Find_Partial_View.
5043 2017-09-06 Javier Miranda <miranda@adacore.com>
5045 * g-catiio.ads, g-catiio.adb (Value): Extended to parse an UTC time
5048 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5050 * sem_dim.adb (Analyze_Dimension): In an instance, a type

5080 * freeze.adb (Check_Inherited_Conditions): Rewriting
5081 of inherited preconditions and postconditions should only occur
5082 in GNATprove mode, that is, when GNATprove_Mode is True, not to
5083 be confused with SPARK_Mode being On.
5085 2017-09-06 Yannick Moy <moy@adacore.com>

5111 (Hide_Public_Entities): Beef up comment on the algorithm.
5112 Reset the table of subprograms on entry.
5114 2017-09-06 Yannick Moy <moy@adacore.com>

5199 * sem_type.adb (Interface_Present_In_Ancestor): Within an
5200 expression function, or within a spec expression (default value,
5201 etc) a reference to an incomplete type is legal: legality of
5202 the operation will be checked when some related entity (type,
5203 object or subprogram) is frozen.
5205 2017-09-06 Gary Dismukes <dismukes@adacore.com>
5207 * exp_ch5.adb, s-diinio.ads, sem_ch4.adb, s-diflio.ads: Minor spelling

5221 Move Ada.Command_Line.Response_File to System.Response_File,
5222 and make Ada.Command_Line.Response_File into a rename of
5223 System.Response_File. This is to avoid having gnatbind depend
5224 Ada.Command_Line, which would damage the bootstrap process now
5225 that Ada.Command_Line contains modern Ada (the raise expression).
5226 * gnatbind.adb: Avoid dependence on
5227 Ada.Command_Line. Depend on System.Response_File instead
5228 of Ada.Command_Line.Response_File. Change one call to
5229 Ada.Command_Line.Command_Name to use Fill_Arg. Change one call
5230 to Ada.Command_Line.Argument_Count to use Arg_Count.
5231 * gcc-interface/Make-lang.in, Makefile.rtl: Take note of the new files.
5233 2017-09-06 Bob Duff <duff@adacore.com>
5235 * frontend.adb (Frontend): Skip -gnatec=gnat.adc

5240 * exp_ch5.adb (Get_Default_Iterator): Replace
5241 "Assert(False)" with "return Iter", because if an iterable

5243 overriding or inherited default iterator.
5245 2017-09-06 Yannick Moy <moy@adacore.com>
5247 * sem_warn.adb (Warn_On_Suspicious_Index): Improve warning when the

5262 which assumes that cursors can never be controlled.
5263 * exp_util.adb (Requires_Cleanup_Actions): Remove the bogus

5297 procedure is No_Return.
5298 * sem_ch8.adb (Analyze_Subprogram_Renaming): Implement legality
5299 rule in 6.5.1 (7/2): if a renaming is a completion of a subprogram
5300 with No_Return, the renamed entity must be No_Return as well.
5302 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>
5304 * exp_ch5.adb, freeze.adb, exp_ch4.adb, exp_ch6.adb, lib-xref.adb:

5321 * freeze.adb (Freeze_Entity): Do not generate a freeze
5322 node for a generic unit, even if it includes delayed aspect
5323 specifications. Freeze nodes for generic entities must never
5324 appear in the tree that reaches the back-end of the compiler.
5326 2017-09-06 Yannick Moy <moy@adacore.com>
5328 * treepr.adb (Print_Entity_Info): Do not print empty Elist.

5344 * lib-xref.adb (Get_Through_Renamings): Get through subprogram
5345 renamings; also, avoid repeated calls to Renamed_Object when getting
5346 through object renamings.
5348 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5350 * sem_ch3.adb (Array_Type_Declaration): Handle properly an
5351 array type declaration in a private part, when an index is a
5352 subtype indication of a discrete type with a private partial view.
5354 2017-09-06 Javier Miranda <miranda@adacore.com>
5356 * exp_ch4.adb (Expand_Modular_Op): Force generating
5357 temporary to improve the generated code.

5363 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5365 * exp_ch5.adb (Make_Field_Assign): If the type
5366 of the right-hand side has stored constraint, use its values
5367 (except for those that are renamings of parent discriminants)
5368 to produce additional assignments for the discriminants of the
5369 left-hand side, which are invisible in the righ-hand side and
5370 not retrievable as selected components.
5372 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5374 * sem_util.adb (Needs_One_Formal): The first formal of such a
5375 function must be a controlling formal, so that Obj.F (X, Y)
5376 can have the interpretation F(Obj)(X, Y).
5377 * sem_util.ads: Clarify documentation.
5379 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
5381 * table.ads, table.adb: Restore original implementation.

5392 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5394 * sem_ch12.adb (Analyze_Subprogram_Instantiation): Propagate
5395 No_Return flag to instance if pragma applies to generic unit. This
5396 must be done explicitly because the pragma does not appear
5397 directly in the generic declaration (unlike the corresponding
5398 aspect specification).
5400 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
5402 * sem_ch7.adb (Has_Referencer): Move up and expand comment
5403 explaining the test used to detect inlining. Use same test

5407 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5409 * exp_ch4.adb (Handle_Changed_Representation): For an untagged
5410 derived type with a mixture of renamed and constrained parent
5411 discriminants, the constraint for the target must obtain the
5412 discriminant values from both the operand and from the stored
5413 constraint for it, given that the constrained discriminants are
5414 not visible in the object.
5415 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
5416 side may be derived from that of the left-hand side (as in the
5417 case of an assignment with a change of representation) so the
5418 discriminant to be used in the retrieval of the value of the
5419 component must be the entity in the type of the right-hand side.
5421 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>
5423 * sem_ch3.adb, sem_ch7.adb, sem_util.adb, g-debpoo.adb, sem_ch4.adb,

5994 * exp_ch6.adb (Expand_Call_Helper): When locating the
5995 accessibility entity created for an access parameter, handle
5996 properly a reference to a formal of an enclosing subprogram. if
5997 the reference appears in an inherited class-wide condition, it
5998 is the rewriting of the reference in the ancestor expression,
5999 but the accessibility entity must be that of the current formal.

6038 * exp_ch3.adb (Freeze_Type): Do not generate an invariant
6039 procedure body for a local (sub)type declaration within a
6040 predicate function. Invariant checks do not apply to these, and
6041 the expansion of the procedure will happen in the wrong scope,
6042 leading to misplaced freeze nodes.
6044 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6046 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
6047 to analyze generated actions. If the main unit is a body,

6052 * einfo.adb (Declaration_Node): flip branches of
6053 an IF statement to avoid repeated negations in its condition;

6083 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
6084 Refine predicate for the case where the primitive operation
6085 is a renaming of equality. An overriding operation that is
6086 a user-defined renaming of predefined equality inherits its
6087 slot from the overridden operation. Otherwise it is treated
6088 as a predefined op and occupies the same predefined slot as
6089 equality. A call to it is transformed into a call to its alias,
6090 which is the predefined equality. A dispatching call thus uses
6091 the proper slot if operation is further inherited and called
6092 with class-wide arguments.
6094 2017-05-02 Justin Squirek <squirek@adacore.com>
6096 * errout.adb (Set_Msg_Text): Add a case to switch the message

6173 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
6174 parameter Array_Comp to indicate the case of an array object
6175 with null-excluding components.
6176 * checks.adb (Null_Exclusion_Static_Checks):
6177 Call Compile_Time_Constraint_Error instead of
6178 Apply_Compile_Time_Constraint_Error in the component case. Also
6179 call that when Array_Comp is True, with an appropriate warning for
6180 the array component case. Only create an explicit initialization
6181 by null in the case of an object of a null-excluding access type
6182 (and no longer do that in the component case).
6183 * sem_ch3.adb (Check_Component): Add a Boolean parameter
6184 Array_Comp defaulted to False. Pass Empty for the Comp
6185 actual when calling Null_Exclusion_Static_Checks in the case
6186 where Comp_Decl matches Object_Decl, because we don't have a
6187 component in that case. In the case of an object or component
6188 of an array type, pass True for Array_Comp on the recursive call

6193 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
6194 compute the linux priority from the Ada priority. Call this everywhere
6195 required. In particular, the previous version was not doing this
6196 computation when setting the ceiling priority in various places. It
6197 was just converting to C.int, which results in a ceiling that is off
6200 2017-05-02 Ed Schonberg <schonberg@adacore.com>

6306 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
6307 to find primitive ops, instead of using an Identifier that will
6308 later be looked up. This is necessary because these ops are not
6309 necessarily visible at all places where we need to call them.
6310 * exp_util.ads: Minor comment fix.
6312 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6314 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
6315 references are fully conformant if they are both expansions
6316 of the discriminant of a protected type, within one of the
6317 protected operations. One occurrence may be expanded into a

6420 2017-04-28 Bob Duff <duff@adacore.com>
6422 * sem_util.ads, sem_util.adb (Might_Raise): New function
6423 that replaces Is_Exception_Safe, but has the opposite
6424 sense. Is_Exception_Safe was missing various cases -- calls inside
6425 a pragma Debug, calls inside an 'if' or assignment statement,
6426 etc. Might_Raise now walks the entire subtree looking for things
6428 * exp_ch9.adb (Is_Exception_Safe): Remove.
6429 (Build_Protected_Subprogram_Body): Replace call to
6430 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
6431 constants where possible).
6432 * exp_ch7.adb: Rename Is_Protected_Body -->
6433 Is_Protected_Subp_Body. A protected_body is something different

6470 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
6471 that follows an expression function must not be relocated to
6472 the generated body, because it applies to the code that follows.
6474 2017-04-28 Gary Dismukes <dismukes@adacore.com>
6476 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
6477 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
6478 code that might violate the more stringent checking for 'Access
6479 introduced in Ada 2005.
6481 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6483 * a-cforse.adb: minor style fix in comment.
6485 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6487 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also

6501 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6503 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
6504 node between access types, freeze the designated type as well,
6505 so that dispatch table pointers are created in the proper scope,
6506 and not in the constructed body of the expression function.
6508 2017-04-28 Bob Duff <duff@adacore.com>
6510 * alloc.ads (Nodes_Initial): Go back to previous value. The large
6511 value makes large compilations faster, but small compilations slower.
6513 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6515 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
6517 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6519 * erroutc.adb (Compilation_Errors): Do not consider info messages

6533 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6535 * sem_res.adb (In_Instance_Code): New predicate in
6536 Valid_Conversion, to determine whether a type conversion appears
6537 as (or within) an actual for a formal object. Type conversions
6538 in instances are not rechecked in Valid_Conversion because
6539 visibility changes between generic location andi instance may
6540 lead to spurious errors, but conversions within an actual must be
6541 fully checked, and they are not fully resolved when pre-analyzing
6544 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6546 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
6547 New_Copy_Tree instead of Relocate_Node as any subsequent copies
6548 of the relocated node will have mangled Parent pointers.
6549 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
6550 tables used in conjunction with entity and itype replication.
6551 (Visit_Entity): Rewrite the restriction on which entities

6587 (Save_Warnings): Likewise.
6588 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
6589 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
6590 components_to_record.
6591 (gnu_field_to_gnat): New function.
6592 (warn_on_field_placement): Likewise.
6593 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
6594 parameters. Rename local variables and adjust recursive call.
6595 Rework final scan of the field list and implement warnings on the
6596 problematic placement of specific sorts of fields.
6598 2017-04-27 Bob Duff <duff@adacore.com>
6600 * errout.adb, exp_aggr.adb, exp_attr.adb, exp_code.adb, fname.adb,

6605 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
6606 For efficiency, cache results of Is_Internal_File_Name and
6607 Is_Predefined_File_Name in the Units table. This avoids a lot
6608 of repeated text processing.
6610 2017-04-27 Emmanuel Briot <briot@adacore.com>
6612 * g-comlin.adb (Sort_Sections): remove useless test.
6614 2017-04-27 Claire Dross <dross@adacore.com>
6616 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
6617 allow the use of regular equality over elements in contracts.
6618 (Formal_Model): Ghost package containing model functions that are
6619 used in subprogram contracts.
6620 (Current_To_Last): Removed, model functions should be used instead.
6621 (First_To_Previous): Removed, model functions should be used instead.
6622 (Strict_Equal): Removed, model functions should be used instead.
6623 (No_Overlap): Removed, model functions should be used instead.
6624 (Equivalent_Keys): Functions over cursors are removed. They were
6625 awkward with explicit container parameters.
6626 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
6627 allow the use of regular equality over elements in contracts.
6628 (Formal_Model): Ghost package containing model functions that

6637 * gnat1drv.adb: Code cleanup.
6639 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6641 * exp_util.adb (Replace_Entity): The prefix of a 'Result
6642 attribute reference in a post- condition is the subprogram to
6643 which the condition applies. If the condition is inherited
6644 by a type extension, the prefix becomes a reference to the
6645 inherited operation, but there is no need to create a wrapper
6646 for this operation, because 'Result is expanded independently
6647 when elaborating the postconditions.
6649 2017-04-27 Bob Duff <duff@adacore.com>
6651 * sinput.adb: Minor code cleanup.
6652 * namet.adb (Append): Create faster versions of

6658 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
6659 Remove unused function.
6660 * alloc.ads (Nodes_Initial): Use a much larger value, because
6661 the compiler was spending a lot of time copying the nodes table
6662 when it grows. This number was chosen in 1996, so is rather out
6663 of date with current memory sizes. Anyway, it's virtual memory.
6664 Get rid of Orig_Nodes_...; use Node_... instead.
6665 * atree.adb (Lock): Do not release the Nodes tables; it's a
6667 Orig_Nodes_ ==> Nodes_
6668 * nlists.adb: Orig_Nodes_ ==> Nodes_
6669 * g-table.adb: Remove unused "with" clause.
6670 * g-table.ads, table.ads: Remove Big_Table_Type, which should
6671 not be used by clients.
6672 * g-dyntab.adb (Last_Allocated): New function
6673 to encapsulate T.P.Last_Allocated, which I'm thinking of changing.

6699 processing for Ada 83 and instances.
6700 (Object_Access_Level): Merge the processing for indexed components
6701 and selected components.
6702 * uname.adb (Add_Node_Name): Merge the processing for stubs.

6713 of Expand_Dispatching_Call. If the denoted subprogram has a
6714 class-wide precondition, this is the only precondition that
6715 applies to the call, rather that the class-wide preconditions
6716 that may apply to the body that is executed. (This is specified
6719 2017-04-27 Yannick Moy <moy@adacore.com>
6721 * gnat1drv.adb (Adjust_Global_Switches): Issue
6722 a warning in GNATprove mode if the runtime library does not
6723 support IEEE-754 floats.
6725 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6727 * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation
6728 is itself inherited it does not carry any contract information,
6729 so examine its parent operation which is its Alias.
6731 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6733 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
6734 prefix can be an object reference in which case Obj'Image (X)
6735 can only be interpreted as an indexing of the parameterless
6736 version of the attribute.
6737 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
6738 an indexing or a slice operation if the attribute does not require
6739 parameters. In Ada2012 'Image also belongs in this category,
6740 and A'Image (lo .. hi) is legal and must be parsed as a slice.
6742 2017-04-27 Yannick Moy <moy@adacore.com>
6744 * exp_ch4.adb: Minor reformatting.
6745 * gnat1drv.adb (Adjust_Global_Switches): When in GNATprove mode,
6746 disable the CodePeer and C generation modes. Similar to the
6747 opposite actions done in CodePeer mode.

6873 * g-dyntab.ads, g-dyntab.adb: Misc cleanup. Rename

6877 (Move, Release_Threshold).
6878 * g-table.ads, g-table.adb: This is now just a thin wrapper
6879 around g-dyntab.ads/g-dyntab.adb. Add functionality supported
6880 or needed by other tables packages (Save, Restore).

6882 * g-table.ads/g-table.adb.
6883 * namet.h, scos.h, uintp.h: These files are reaching into the

7403 performs this functionality (aka relaxed management). Switch
7404 -gnatd.s may be used to force strict management in which case
7405 the block will manage the secondary stack unconditionally. Add
7406 a guard to stop the traversal when encountering a package or a
7409 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7411 * sem_res.adb (Resolve_Call): Refine further the handling of
7412 limited views of return types in function calls. If the function
7413 that returns a limited view appears in the current unit,
7414 we do not replace its type by the non-limited view because
7415 this transformation is performed int the back-end. However,
7416 the type of the call itself must be the non-limited view, to
7417 prevent spurious resolution errors.
7419 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7421 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
7422 Removed, proposed implementation using generics for class-wide
7423 preconditions proved impractical.
7424 (Class_Wide_Clone): New attribute of subprogram. Designates
7425 subprogram created for primitive operations with class-wide
7426 pre/postconditions that contain calls to other primitives. The
7427 clone holds the body of the original primitive, but the
7428 pre/postonditions do not apply to it. The original body is
7429 rewritten as a wrapper for a call to the clone.
7430 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
7431 the flag is set, no code for the corresponding pre/postconditions
7432 is inserted into its body.
7434 2017-04-27 Bob Duff <duff@adacore.com>
7436 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore

7504 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
7505 point type actual that has user-defined arithmetic primitives,
7506 when there is a previous actual for a formal package that defines
7507 a fixed-point type with the parent user-defined operator.

7523 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
7524 dimensions of operands if node has been analyzed already, because
7525 previous analysis and dimension checking will have removed the
7526 dimension information from the operands.

7613 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
7614 * sinput-p.adb: Use regular fat pointers, with bounds checking,
7615 for source buffers. Fix misc obscure bugs.
7616 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
7617 checking, for source buffers. Modify representation clause for
7618 Source_File_Record as appropriate. Move Source_File_Index_Table
7619 from spec to body, because it is not used outside the body.
7620 Move Set_Source_File_Index_Table into the private part, because
7621 it is used only in the body and in children. Use trickery to
7622 modify the dope in the generic instantiation case. It's ugly,
7623 but not as ugly as the previous method. Fix documentation.
7624 Remove obsolete code.

7640 expander is not active or when index/range checks are suppressed
7642 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
7643 Remove variants that include a Supress parameter. These routines
7644 are never used, and were introduced before the current scope-based
7645 check suppression method.

7696 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
7697 the Internal_Source buffer. This removes the incorrect call to "="
7698 the customer noticed.
7699 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
7700 eventually need to eliminate them altogether. Or else get rid
7701 of zero-origin addressing.

7985 further expansion for the unchecked union.
7986 (Expand_Attribute_Reference, case 'Write): If the type is
7987 an unchecked_union, check whether enclosing scope is a Write
7988 subprogram. Replace attribute with a Raise_Program_Error if the
7989 discriminants of the unchecked_union type have not default values

8210 to return if an interface type is encountered and add
8211 condition to convert the formal parameter to its class-wide
8212 counterpart if Work_Typ is abstract.

8234 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
8235 (10-15): if derived type T with progenitors is abstract,
8236 and primitive P of this type inherits non-trivial classwide
8237 preconditions from both a parent operation and from an interface
8238 operation, then the inherited operation is abstract if the parent
8239 operation is not null.
8240 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface

8280 * a-numeri.ads: Change the encoding of Greek letter Pi from
8281 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
8282 to indicate the encoding. We considered using a byte order mark
8283 (BOM), but that causes various trouble (misc software eats the
8284 BOM, if you have a patch with a BOM, then it's not at the start
8285 of the patch, so it's not a BOM, the BOM affects with-ing files,

8415 (Instantiate_Package_Body): Save and restore the value of global
8416 flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set the value of
8417 global flag Ignore_SPARK_Mode_Pragmas_In_Instance when the
8418 corresponding instance spec also ignored all SPARK_Mode pragmas
8420 (Instantiate_Subprogram_Body): Save and restore the
8421 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
8422 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
8423 when the corresponding instance spec also ignored all SPARK_Mode
8424 pragmas found within.
8425 * sem_prag.adb (Analyze_Pragma): Update the reference to
8426 Ignore_Pragma_SPARK_Mode.
8427 * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
8428 all SPARK_Mode pragmas defined within yields mode "off".
8430 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8432 * bindgen.adb, exp_dbug.adb, errout.adb, fname.adb: Minor reformatting.
8434 2017-04-25 Bob Duff <duff@adacore.com>
8436 * exp_atag.adb (Build_CW_Membership): Add "Suppress =>
8437 All_Checks" to avoid generating unnecessary checks.
8438 * exp_ch4.adb (Expand_N_In, Make_Tag_Check): Add "Suppress =>
8440 * sem.ads: Fix comment.
8441 * expander.ads: Fix comment.
8442 * exp_atag.ads: Fix comment: "Index = 0" should be
8445 2017-04-25 Gary Dismukes <dismukes@adacore.com>
8447 * s-taprop-linux.adb: Minor editorial fixes.
8449 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8451 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
8452 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
8453 variable and set it to True whenever the main hash table is
8454 populated. Short- circuit the Assoc function if it is false
8455 and add associated guards.
8457 2017-04-25 Olivier Hainque <hainque@adacore.com>
8459 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
8460 specs without elaboration code that have an elaboration counter
8461 nevertheless, e.g. when compiled with -fpreserve-control-flow.
8462 * sem_ch10.adb (Analyze_Compilation_Unit):
8463 Set_Elaboration_Entity_Required when requested to preserve
8464 control flow, to ensure the unit elaboration is materialized at
8465 bind time, resulting in the inclusion of the unit object file
8466 in the executable closure at link time.
8468 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
8470 * exp_dbug.adb: In Debug_Renaming_Declaration,
8471 when dealing with indexed component, accept to produce a renaming
8472 symbol when the index is an IN parameter or when it is a name
8473 defined in an outer scope.
8475 2017-04-25 Yannick Moy <moy@adacore.com>
8477 * errout.adb (Error_Msg): Adapt continuation
8478 message in instantiations and inlined bodies for info messages.
8480 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8482 * fname.adb (Has_Internal_Extension): Add pragma Inline.
8483 Use direct 4-character slice comparisons.
8485 pragma Inline. (Has_Suffix): Delete.
8486 (Is_Internal_File_Name):
8487 Test Is_Predefined_File_Name first.
8488 (Is_Predefined_File_Name):
8489 Use direct slice comparisons as much as possible and limit all
8490 comparisons to at most 8 characters.
8492 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8494 * checks.adb (Insert_Valid_Check): Code cleanup.
8495 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
8496 (Expand_Actuals): Generate proper copy-back for a validation
8497 variable when it acts as the argument of a type conversion.
8498 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
8499 predicate to operate on type qualifications.
8501 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8503 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
8506 2017-04-25 Bob Duff <duff@adacore.com>
8508 * sem_prag.adb (No_Return): Give an error if the pragma applies
8509 to a body. Specialize the error for the specless body case,
8510 as is done for (e.g.) pragma Convention.
8511 * debug.adb: Add switch -gnatd.J to disable the above legality
8512 checks. This is mainly for use in our test suite, to avoid
8513 rewriting a lot of illegal (but working) code. It might also
8514 be useful to customers. Under this switch, if a pragma No_Return
8515 applies to a body, and the procedure raises an exception (as it
8516 should), the pragma has no effect. If the procedure does return,
8517 execution is erroneous.
8519 2017-04-25 Bob Duff <duff@adacore.com>
8521 * exp_ch6.adb (Expand_Actuals): This is the
8522 root of the problem. It took N as an 'in out' parameter, and in
8523 some cases, rewrote N, but then set N to Original_Node(N). So
8524 the node returned in N had no Parent. The caller continued
8525 processing of this orphaned node. In some cases that caused a
8526 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
8527 and trips over the Empty Parent). The solution is to make N an
8528 'in' parameter. Instead of rewriting it, return the list of
8529 post-call actions, so the caller can do the rewriting later,
8530 after N has been fully processed.
8531 (Expand_Call_Helper): Move most of Expand_Call here. It has
8532 too many premature 'return' statements, and we want to do the
8533 rewriting on return.
8534 (Insert_Post_Call_Actions): New procedure to insert the post-call
8535 actions in the appropriate place. In the problematic case,
8536 that involves rewriting N as an Expression_With_Actions.
8537 (Expand_Call): Call the new procedures Expand_Call_Helper and
8538 Insert_Post_Call_Actions.
8540 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8542 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
8543 properly type derived from generic formal types, to handle
8544 properly modified version of ACATS 4.1B B611017.
8546 2017-04-25 Javier Miranda <miranda@adacore.com>
8548 * exp_unst.adb (Subp_Index): Adding missing
8549 support for renamings and functions that return a constrained
8550 array type (i.e. functions for which the frontend built a
8551 procedure with an extra out parameter).
8553 2017-04-25 Pascal Obry <obry@adacore.com>
8555 * s-string.adb: Minor code clean-up.
8557 2017-04-25 Bob Duff <duff@adacore.com>

8562 function for Non_Blocking_Wait_Process.
8564 2017-04-25 Bob Duff <duff@adacore.com>
8566 * prep.adb (Preprocess): Remove incorrect
8567 Assert. Current character can be ASCII.CR.
8569 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8571 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
8572 convention Stdcall, which has a number of exceptions. Convention
8573 is legal on a component declaration whose type is an anonymous
8574 access to subprogram.
8576 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8578 * sem_ch4.adb: sem_ch4.adb Various reformattings.
8579 (Try_One_Prefix_Interpretation): Use the base type when dealing
8580 with a subtype created for purposes of constraining a private
8581 type with discriminants.
8583 2017-04-25 Javier Miranda <miranda@adacore.com>
8585 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.

8587 dispatching primitives (Restore_Warnings): Restore warning on
8588 late dispatching primitives (Save_Warnings): Save warning on late
8589 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
8590 to enable/disable this warning.
8591 (WA_Warnings): Set warning on late dispatching primitives.
8592 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
8593 that its parent type has a private extension.
8594 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
8596 * usage.adb: Document -gnatw.j and -gnatw.J.
8598 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8600 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
8603 2017-04-25 Bob Duff <duff@adacore.com>
8605 * binde.adb (Validate): Do not pass dynamic strings
8606 to pragma Assert, because older compilers do not support that.
8608 2017-04-25 Bob Duff <duff@adacore.com>
8610 * s-fileio.adb (Close): When a temp file is
8611 closed, delete it and clean up its Temp_File_Record immediately,
8612 rather than waiting until later.
8613 (Temp_File_Record): Add File
8614 component, so Close can know which Temp_File_Record corresponds
8615 to the file being closed.
8616 (Delete): Don't delete temp files,
8617 because they are deleted by Close.
8618 (Open): Set the File component
8619 of Temp_File_Record. This requires moving the creation of the
8620 Temp_File_Record to the end, after the AFCB has been created.
8622 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8624 * checks.adb (Insert_Valid_Check): Do not generate
8625 a validity check when inside a generic.
8627 2017-04-25 Yannick Moy <moy@adacore.com>
8629 * sem_res.adb (Resolve_Type_Conversion): Fix bad logic.
8631 2017-04-25 Arnaud Charlet <charlet@adacore.com>
8633 * snames.ads-tmpl (Snames): More names for detecting predefined
8634 potentially blocking subprograms.
8636 2017-04-25 Ed Schonberg <schonberg@adacore.com>

8639 concerning inheritance of class-wide preconditions do not apply
8642 2017-04-25 Bob Duff <duff@adacore.com>
8644 * s-ficobl.ads: Minor comment fix.
8646 2017-04-25 Yannick Moy <moy@adacore.com>
8648 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
8649 conversions from float to integer in GNATprove mode.
8650 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
8651 to call Apply_Type_Conversion_Checks, so that range checks
8652 are properly positioned when needed on conversions, including
8653 when converting from float to integer. (Determine_Range): In
8654 GNATprove mode, take into account the possibility of conversion
8655 from float to integer.
8656 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
8657 check on conversions from fixed-point to integer, not anymore
8658 on conversions from floating-point to integer, when in GNATprove
8661 2017-04-25 Yannick Moy <moy@adacore.com>
8663 * checks.adb (Determine_Range_R): Special case type conversions
8664 from integer to float in order to get bounds in that case too.
8665 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
8666 mode, for computations involved in interval checking.

8678 (Validated_Object): New routine along with pragma Inline.
8679 (Set_Validated_Object): New routine along with pragma Inline.
8680 * exp_attr.adb (Make_Range_Test): Add processing for validation
8681 variables to avoid extra reads and copies of the prefix.
8682 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
8683 variables in order to reflect any changes done in the variable
8684 back into the original object.
8685 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
8686 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

8692 generate Finalize_Address routines for CodePeer.
8694 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8696 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
8697 Analyze_Pre_Post_Condition, to implement the legality checks
8698 mandated by AI12-0131: Pre'Class shall not be specified for an
8699 overriding primitive subprogram of a tagged type T unless the
8700 Pre'Class aspect is specified for the corresponding primitive
8701 subprogram of some ancestor of T.
8703 2017-04-25 Bob Duff <duff@adacore.com>
8705 * sem_ch8.adb (Use_One_Type): If a use_type_clause
8706 is redundant, set its Used_Operations to empty. This is only
8707 necessary for use clauses that appear in the parent of a generic
8708 child unit, because those use clauses get reanalyzed when we
8709 instantiate the generic, and we don't want the Used_Operations
8710 carried over from the original context (where it was probably
8713 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8715 * exp_ch6.adb: Minor reformatting.
8717 2017-04-25 Bob Duff <duff@adacore.com>

8722 (Current_Sem_Unit) to find the correct casing.
8723 * par.adb (Par): Null out Current_Source_File, to ensure that
8724 the above bugs won't rear their ugly heads again.
8726 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8728 * sem_ch8.adb (Find_Type): For an attribute reference
8729 'Class, if prefix type is synchronized and previous errors
8730 have suppressed the creation of the corresponding record type,
8731 create a spurious class-wide for the synchonized type itself,
8732 to catch other misuses of the attribute
8734 2017-04-25 Steve Baird <baird@adacore.com>
8736 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode
8737 is True, then don't generate the accessibility check for the
8738 tag of a tagged result.
8739 * exp_intr.adb (Expand_Dispatching_Constructor_Call):
8740 if CodePeer_Mode is True, then don't generate the
8741 tag checks for the result of call to an instance of
8742 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
8743 descendant of" check and the accessibility check).
8745 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8747 * sem_ch13.adb: Code cleanups.
8748 * a-strbou.ads: minor whitespace fix in Trim for bounded strings.

8753 * exp_ch4.adb (Library_Level_Target): New function.
8754 (Expand_Concatenate): When optimization is enabled, also expand
8755 the operation out-of-line if the concatenation is present within
8756 the expression of the declaration of a library-level object and
8757 not only if it is the expression of the declaration.
8759 2017-04-25 Bob Duff <duff@adacore.com>
8761 * freeze.adb (Freeze_Object_Declaration): Do
8762 not Remove_Side_Effects if there is a pragma Linker_Section,
8763 because in that case we want static initialization in the
8764 appropriate section.
8766 2017-04-25 Gary Dismukes <dismukes@adacore.com>
8768 * exp_dbug.adb: Minor rewording and reformatting.

8772 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
8773 handle the proposed changes to rules concerning potentially
8774 unevaluated expressions, to include selected components that
8775 do not depend on discriminants, and indexed components with
8777 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
8778 predicate in quantified expression, and fix bugs in the handling
8779 of case expressions and membership test.
8780 (Analyze_Attribute_Old_Result): use new predicate.
8781 (Analyze_Attribute, case Loop_Entry): ditto.
8783 2017-04-25 Bob Duff <duff@adacore.com>
8785 * s-secsta.adb (SS_Info): Add a comment
8786 explaining why we don't need to walk all the chunks in order to
8787 compute the total size.
8789 2017-04-25 Bob Duff <duff@adacore.com>
8791 * namet.ads, namet.adb (Global_Name_Buffer): Increase the length
8792 of the global name buffer to 4*Max_Line_Length.
8794 2017-04-25 Javier Miranda <miranda@adacore.com>
8796 * exp_ch8.adb (Expand_N_Object_Renaming_Declaration): When creating a
8797 renaming entity for debug information, mark the entity as needing debug
8798 info if it comes from sources.
8800 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8802 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the
8803 restriction converning the use of 'Address where the prefix is
8804 of a controlled type.
8806 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
8808 * exp_dbug.adb: In Debug_Renaming_Declaration,
8809 skip slices that are made redundant by an indexed component

8822 internal calls that appear in preconditions of protected
8823 operations, in default values for same, and in contract guards
8824 for contract cases in SPARK.

8828 * a-numaux.ads: Fix description of a-numaux-darwin
8830 (Double): Define to Long_Float.
8831 * a-numaux-vxworks.ads (Double): Likewise.
8832 * a-numaux-darwin.ads
8834 * a-numaux-libc-x86.ads (Double): Define to Long_Long_Float.
8835 * a-numaux-x86.ads: Fix package description.
8836 * a-numaux-x86.adb (Is_Nan): Minor tweak.
8837 (Reduce): Adjust and complete description. Call Is_Nan instead of
8838 testing manually. Use an integer temporary to hold rounded value.
8839 * a-numaux-darwin.adb (Reduce): Likewise.

8845 on analysis of prefix whose type is a current instance of a
8846 synchronized type, but where the prefix itself is an entity that

8851 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
8852 the identity of callable entities therein, because they have been
8853 properly resolved, and prefixed calls may have been rewritten
8856 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
8858 * exp_ch3.adb (Build_Init_Statements): Convert
8859 the expression of the pragma/aspect Secondary_Stack_Size to
8860 internal type System.Parameters.Size_Type before assigning
8861 it to the Secondary_Stack_Size component of the task type's
8862 corresponding record.
8864 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8866 * sem_eval.adb (Compile_Time_Compare): Reinstate the expr+literal
8867 (etc) optimizations when the type is modular and the offsets
8870 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8872 * s-osinte-freebsd.ads: Minor comment tweaks
8874 2017-04-25 Javier Miranda <miranda@adacore.com>
8876 * urealp.adb (UR_Write): Reverse previous patch
8877 adding documentation on why we generate multiplications instead
8878 of divisions (needed to avoid expressions whose computation with
8879 large numbers may cause division by 0).
8881 2017-04-25 Bob Duff <duff@adacore.com>
8883 * erroutc.adb (Set_Specific_Warning_Off,
8884 Set_Warnings_Mode_Off): Use the correct source file for
8885 Stop. Was using Current_Source_File, which is only valid during
8886 parsing. Current_Source_File will have a leftover value from
8887 whatever file happened to be parsed last, because of a with_clause
8890 2017-04-25 Bob Duff <duff@adacore.com>
8892 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
8893 to In_Predefined_Unit, but including GNAT units.
8894 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
8895 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
8896 because Should_Ignore_Pragma was not working reliably outside
8897 the parser, because Current_Source_File is not valid.
8898 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
8899 * par-prag.adb: Call Should_Ignore_Pragma_Par.

8966 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8968 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
8969 of prefix whose type is a current instance of a synchronized
8970 type. If the prefix is an object this is an external call (or
8971 requeue) that can only access public operations of the object. The
8972 previous predicate was too restrictive, and did not allow public
8973 protected operations, only task entries.
8975 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8977 * sem_ch5.adb, fname.adb: Minor reformatting.
8979 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8981 * einfo.adb (Is_Anonymous_Access_Type): New routine.
8982 * einfo.ads Update the placement of
8983 E_Anonymous_Access_Subprogram_Type along with all subtypes that
8985 (Is_Anonymous_Access_Type): New routine.
8986 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
8987 master for an access type subject to pragma No_Heap_Finalization.
8988 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
8989 allocated or deallocated does not finalization actions if the
8990 associated access type is subject to pragma No_Heap_Finalization.
8991 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
8992 * par-prag.adb Pragma No_Heap_Finalization does not need special
8993 processing from the parser.
8994 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
8995 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
8996 * sem_prag.adb Add an entry in table Sig_Flags for pragma
8997 No_Heap_Finalization.
8998 (Analyze_Pragma): Add processing for
8999 pragma No_Heap_Finalization. Update various error messages to
9000 use Duplication_Error.

9002 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
9003 and corresponding pragma id.

9007 * freeze.adb (Freeze_Record_Type): Use the
9008 underlying type of the component type to determine whether it's
9009 elementary. For representation clause purposes, a private type
9010 should behave the same as its full type.
9011 * fname.ads, fname.adb (Is_Predefined_File_Name):
9012 Make sure things like "system.ali" are recognized as predefined.
9014 2017-04-25 Javier Miranda <miranda@adacore.com>

9021 element iterator when the name is an overloaded function call,
9022 one of whose interpretations yields an array.
9024 2017-04-25 Bob Duff <duff@adacore.com>
9026 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
9027 Is_Internal_Unit_Name): New functions for operating on unit
9028 names, as opposed to file names. There's some duplicated code
9029 with fname.adb, which is unfortunate, but it seems like we don't
9030 want to add dependencies here.
9031 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
9032 to Is_Predefined_Unit_Name; the former was wrong, because Uname
9033 is not a file name at all.
9034 * fname.ads, fname.adb: Document the fact that
9035 Is_Predefined_File_Name and Is_Internal_File_Name can be called
9036 for ALI files, and fix the code so it works properly for ALI
9037 files. E.g. these should return True for "system.ali".
9039 2017-04-25 Justin Squirek <squirek@adacore.com>
9041 * exp_util.adb (Add_Invariant): Removed,
9042 code moved to Add_Invariant_Check, Add_Inherited_Invariant,

9051 and integrated code from Add_Parent_Invariants and
9052 Add_Interface_Invariants.
9053 (Process_Type): Removed, the
9054 relavant code was inlined into both Add_Own_Invariant and
9055 Add_Inherited_Invariant.

9081 (Replace_Type_References):
9082 Append an extra parameter to allow for dispatching replacements
9083 and add the corrasponding logic.
9084 (Type_Invariant): Remove
9085 Replace_Typ_Refs and replace its references with calls to
9086 Replace_Type_References.
9087 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
9089 2017-04-25 Bob Duff <duff@adacore.com>

9094 when compiling predefined files.
9095 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
9096 "gnat.adc" should not be considered a predefined file name.
9097 That required (or at least encouraged) a lot of cleanup of global
9098 variable usage. We shouldn't be communicating information via
9099 the global name buffer.
9100 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
9101 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

9161 the first pass over an assignment statement with target names,
9162 to prevent the generation of subtypes (such as discriminated

9201 DIC pragma is placed at the top of a declarative region.
9203 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>

9211 the error message when the attribute reference is an actual in
9212 a call to a subprogram inherited from a generic formal type with
9213 unknown discriminants, which makes the subprogram and its formal
9214 parameters intrinsic (see RM 6.3.1 (8) and (13)).

9990 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
9991 an object declaration for an array type with a modular index type
9992 with the size of Long_Long_Integer. Special processing is needed
9993 in this case to compute reliably the size of the object, and
9994 eventually to raise Storage_Error, when wrap-around arithmetic
9995 might compute a meangingless size for the object.
9997 2017-01-23 Justin Squirek <squirek@adacore.com>

10005 it is deciding whether to turn the call into an indexed
10006 component, avoid doing so if the call is to an instance of

10008 indexed component, and resolution of that turns it back into a
10009 function call, and so on, resulting in infinite recursion.
10010 * sem_util.adb (Needs_One_Actual): If the first formal has a
10011 default, then return False.

10113 returns a limited view of a type and at the point of the call the
10114 function is not declared in the extended main unit then replace
10115 it with the non-limited view, which must be available. If the
10116 called function is in the extended main unit then no action is
10117 needed since the back-end handles this case.

10418 explicitly marked as pure for optimization purposes.
10419 * exp_aggr.adb: Minor reformatting.
10421 2017-01-19 Javier Miranda <miranda@adacore.com>
10423 * exp_ch6.adb (Expand_Call): Remove side effects on
10424 actuals that are allocators with qualified expression since the
10425 initialization of the object is performed by means of individual
10426 statements (and hence it must be done before the call).
10428 2017-01-19 Ed Schonberg <schonberg@adacore.com>
10430 * sem_ch3.adb (Analyze_Declarations): Minor reformatting.
10431 (Build_Derived_Enumeration_Type): If the derived type inherits a
10432 dynamic predicate from its parent, the bounds of the type must
10433 freeze because an explicit constraint is constructed for the
10434 type and the corresponding range is elaborated now.
10436 2017-01-19 Arnaud Charlet <charlet@adacore.com>
10438 * sem_attr.ads: minor fix of inconsistent casing in comment
10439 * lib-writ.ads: minor align comments in columns

10445 * sem_ch12.adb: minor whitespace fix
10446 * freeze.adb: Add comment.
10447 * sem_util.adb (Unique_Name): for instances of
10448 generic subprograms ignore the name of the wrapper package.
10450 2017-01-19 Javier Miranda <miranda@adacore.com>
10452 * exp_aggr.adb (Resolve_Record_Aggregate):
10453 Factorize code needed for aggregates of limited and unlimited
10454 types in a new routine.
10455 (Pass_Aggregate_To_Back_End): New subprogram.
10457 2017-01-19 Yannick Moy <moy@adacore.com>
10459 * sinfo.adb (Pragma_Name): Only access up to Last_Pair of Pragma_Map.
10461 2017-01-19 Ed Schonberg <schonberg@adacore.com>
10463 * sem_ch4.ads, sem_ch4.adb (Try_Object_Operation): Make subprogram
10464 public, for use elsewhere.
10465 * sem_ch6.adb (Analyze_Procedure_Call): In SPARK_Mode and within
10466 an Inlined_body, recognize a call that uses object notation
10467 and has not been rewritten as a regular call because regular
10468 expansion has not taken place.
10470 2017-01-19 Bob Duff <duff@adacore.com>
10472 * checks.adb (Apply_Type_Conversion_Checks): Disable small optimization
10473 in case of generic formal discrete types, because it causes crashes in
10474 the compiler when built with assertions on.
10476 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
10478 * lib-xref-spark_specific.adb, sem_util.adb, sem_util.ads,
10479 sem_ch4.adb, sem_ch8.adb, lib-xref.ads: Minor reformatting.
10481 2017-01-19 Bob Duff <duff@adacore.com>
10483 * bcheck.adb (Check_Consistent_Dynamic_Elaboration_Checking):
10484 Increment Warnings_Detected. It was decrementing, which is
10485 wrong since we just issued a warning message.
10486 * binderr.ads (Errors_Detected, Warnings_Detected): Declare
10487 these variables to be of subtype Nat instead of Int, because
10488 they should never be negative.
10490 2017-01-19 Javier Miranda <miranda@adacore.com>
10492 * contracts.adb (Build_Postconditions_Procedure): Replace
10493 Generate_C_Code by Modify_Tree_For_C.

10506 * sem_res.adb (Resolve_Type_Conversion): Replace Generate_C_Code
10507 by Modify_Tree_For_C.
10508 * sinfo.ads (Modify_Tree_For_C): Adding documentation.
10510 2017-01-19 Javier Miranda <miranda@adacore.com>
10512 * sem_util.ads, sem_util.adb (Expression_Of_Expression_Function): New
10514 (Is_Inlinable_Expression_Function): New subprogram.
10515 * exp_ch6.ads, exp_ch6.adb (Expression_Of_Expression_Function): Moved
10517 (Is_Inlinable_Expression_Function): Moved to Sem_Util.
10519 2017-01-19 Ed Schonberg <schonberg@adacore.com>
10521 * sem_ch4.adb (Diagnose_Call): Improve error message when a
10522 selected component has a prefix that might be interpreted
10523 as a parameterless function call, but none of the candidate
10524 interpretations is parameterless, and there is a hidden homonym
10525 of the prefix that is a package.
10526 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
10527 interpreted as a parameterless function call and its analysis
10528 fails, do not call Analyze_Selected_Component.
10530 2017-01-19 Steve Baird <baird@adacore.com>
10532 * sem_util.ads: Add new Use_Full_View Boolean parameter to
10534 * sem_util.adb (Get_Index_Bounds): replace calls to Scalar_Range with
10535 calls to a newly-defined Scalar_Range_Of_Right_View function.
10537 2017-01-19 Arnaud Charlet <charlet@adacore.com>
10539 * gnat1drv.adb: minor fix of unbalanced parens in comment
10540 * lib-xref.ads (Traverse_Compilation_Unit): declaration moved
10541 to visible part of the package to allow re-use in GNATprove.
10542 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
10543 from repeated code of Traverse_Compilation_Unit.
10544 (Traverse_Declaration_Or_Statement): fixed detection of
10545 generic subprograms and packages; also, iteration over case
10546 statement alternatives rewritten to avoid testing if the first
10547 alternative is present (since it must be present due to Ada
10548 syntax restrictions).
10550 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
10552 * exp_ch6.adb (Expand_N_Subprogram_Body): Mark the spec as
10553 returning by reference not just for subprogram body stubs,
10554 but for all subprogram cases.
10555 * sem_util.adb: Code reformatting.
10556 (Requires_Transient_Scope): Update the call to Results_Differ.
10557 (Results_Differ): Update the parameter profile and the associated
10560 2017-01-19 Ed Schonberg <schonberg@adacore.com>
10562 * sem_dim.adb (Analyze_Dimension): Analyze object declaration and
10563 identifier nodes that do not come from source, to handle properly
10564 dimensionality check within an inlined body which inclddes both
10565 original operands and rewritten operands. This removes spurious
10566 dimensionality errors in the presence of front-end inlining,
10567 as well as in SPARK mode.
10569 2017-01-16 Jakub Jelinek <jakub@redhat.com>
10572 * gcc-interface/lang.opt (gant, gnatO, gnat): Add Driver flag.
10574 2017-01-13 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE>

10607 * einfo.ads: minor grammar fixes in comment of Normalized_Position_Max.
10608 * scil_ll.adb: Minor style fix in comment.
10609 * sem_ch8.adb (Analyze_Expanded_Name): Perform dimension analysis
10610 even if entity is already set, because the node may be renalyzed
10611 after inlining transformations.
10613 2017-01-13 Javier Miranda <miranda@adacore.com>
10615 * sem_res.adb (Resolve_Call): Do not establish a transient scope
10616 for a call to inlinable expression function (since the call will
10617 be replaced by its returned object).
10618 * exp_ch6.ads (Is_Inlinable_Expression_Function): New subprogram.
10619 * exp_ch6.adb (Expression_Of_Expression_Function): New subprogram.
10620 (Expand_Call): For inlinable expression function call replace the
10621 call by its returned object.

10624 2017-01-13 Gary Dismukes <dismukes@adacore.com>
10626 * checks.adb: Minor typo fix and reformatting.
10628 2017-01-13 Javier Miranda <miranda@adacore.com>
10630 * contracts.adb (Contract_Only_Subprograms): Remove formal.
10631 (Copy_Original_Specification): Removed.
10632 (Skip_Contract_Only_Subprogram): Move here checks previously
10633 located in the caller of this routine (to leave the code more clean).
10634 (Build_Contract_Only_Subprogram): Code cleanup.
10635 * scil_ll.ads, scil_ll.adb (Get_Contract_Only_Body_Name): Removed.

10638 2017-01-13 Javier Miranda <miranda@adacore.com>
10640 * sem_ch6.adb (Cloned_Expression): New subprogram.
10641 (Freeze_Expr_Types): Complete previous patch since the expression
10642 of an expression-function may have iterators and loops with
10643 defining identifiers which, as part of the preanalysis of the
10644 expression, may be left decorated with itypes that will not be
10645 available in the tree passed to the backend.
10647 2017-01-13 Ed Schonberg <schonberg@adacore.com>

10650 conversion to Integer of an expression that is an attribute
10651 reference 'Pos on an enumeration type.
10653 2017-01-13 Bob Duff <duff@adacore.com>

10660 calls in accessibility check on return statement.
10662 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
10664 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
10665 Ensure that the input body is a subprogram body before trying to
10666 determine whether it denoted an expression function. Note that
10667 subprogram body stubs cannot denote expression functions.
10669 2017-01-13 Gary Dismukes <dismukes@adacore.com>
10671 * bindgen.adb, sem_ch6.adb, binde.adb, exp_ch3.adb: Minor reformatting
10674 2017-01-13 Javier Miranda <miranda@adacore.com>
10676 * einfo.ads (Component_Bit_Offset): Fix documentation.
10677 * sem_ch13.adb (Check_Record_Representation_Clause): Skip check
10678 on record holes for components with unknown compile-time offsets.
10680 2017-01-13 Bob Duff <duff@adacore.com>
10682 * ali.ads, ali.adb (Static_Elaboration_Model_Used): Remove unused flag.
10683 * g-locfil.ads: Minor comment fix.
10685 2017-01-13 Bob Duff <duff@adacore.com>
10687 * binde.adb (Elab_New): New elaboration order algorithm
10688 that is expected to cause fewer ABE issues. This is a work in
10689 progress. The new algorithm is currently disabled, and can be
10690 enable by the -dp switch, or by modifying the Do_Old and Do_New
10691 etc. flags and rebuilding. Experimental code is included to
10692 compare the results of the old and new algorithms.
10693 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
10694 can have multiple of these tables, so the old and new algorithms
10696 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
10697 parameter of type array. This avoids the global variable, and
10698 allows bounds checking (which is normally defeated by the tables
10699 packages). It also ensures that the Elab_Order is read-only
10701 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
10702 subprograms that need it, as above.
10703 * debug.adb: Document new -dp switch. Modify doc of old -do
10705 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
10706 and Bindgen. Move writing of closure (-R and -Ra switches)
10707 to Binde; that's more convenient.
10709 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10711 * sem_ch6.adb (Analyze_Expression_Function): If the expression
10712 function is a completion, all entities referenced in the
10713 expression are frozen. As a consequence, a reference to an
10714 uncompleted private type from an enclosing scope is illegal.
10716 2017-01-13 Javier Miranda <miranda@adacore.com>
10718 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
10719 (Analyze_Subprogram_Body_Helper): At the occurrence of an
10720 expression function declaration that is a completion, its
10721 expression causes freezing (AI12-0103).
10723 2017-01-13 Vadim Godunko <godunko@adacore.com>
10725 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and
10726 Reference functions of Ada.Containers.Indefinite_Holders.
10728 2017-01-13 Bob Duff <duff@adacore.com>
10730 * s-os_lib.ads: Minor comment fixes.
10732 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
10734 * exp_ch3.adb (Default_Initialize_Object): Do not default
10735 initialize an object when it is of a task type and restriction
10736 No_Tasking is in effect because the initialization is obsolete.
10737 * exp_ch9.adb (Build_Master_Entity): Do not generate a master when
10738 restriction No_Tasking is in effect.
10739 (Build_Master_Renaming): Do not rename a master when restriction
10740 No_Tasking is in effect.
10742 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10744 * sem_aggr.adb (Resolve_Array_Aggregate): The code that verifies
10745 the legality of An others clause applies as well to a choice in
10746 an Iterated_component_ association.
10747 (Resolve_Iterated_Component_Association): An others choice
10749 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
10750 Iterated_Component_Association is not static.
10752 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>

10758 Analyze_Subprogram_Instantiation): Mark the Ghost mode as set

10771 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10773 * sem_util.ads, sem_util.adb (Choice_List): Move function here
10774 from sem_aggr.adb, for use elsewhere.
10775 * sem_ch3.adb (Analyze_Object_Declaration): Use Choice_List.
10776 * sem_aggr.adb (Resolve_Array_Aggregate): Remove
10777 Iterated_Component_Present.
10778 * exp_aggr.adb: Use Choice_List throughout, to handle
10779 Iterated_Component_Associations.
10780 (Gen_Loop): Generate proper loop for an
10781 Iterated_Component_Association: loop variable has the identifier
10782 of the original association. Generate a loop even for a single
10783 component choice, in order to make loop parameter visible in
10785 (Flatten): An Iterated_Component_Association is not static.
10787 2017-01-13 Yannick Moy <moy@adacore.com>
10789 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
10790 float exponentiation for statically known small negative values
10791 is the reciprocal of the exponentiation for the opposite value
10793 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
10794 Ensure that the value of float exponentiation for negative values
10795 is the reciprocal of the exponentiation for the opposite value
10797 * inline.adb (Expand_Inlined_Call): Fix the count
10798 for the number of generated gotos.
10800 2017-01-13 Yannick Moy <moy@adacore.com>
10802 * inline.adb: Code cleanup.

10804 expression in delay statement as OK for volatile context.
10806 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10808 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
10809 mode a choice that is a subtype with a static predicate is
10810 replaced by the values it covers. This transformation must not
10811 be performed in ASIS mode, to preserve the source for analysis.
10813 2017-01-13 Justin Squirek <squirek@adacore.com>

10827 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
10828 and resolve the discrete choices and the expression of the
10830 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
10831 Loop_Actions and Box_Present are attributes of
10832 N_Iterated_Component_Association nodes. Box_Present is always
10833 False in this case.
10834 * sprint.adb (Sprint_Node): An Iterated_Component_Association
10835 has a Discrete_Choices list, as specified in the RM. A
10836 Component_Association for aggregate uses instead a Choices list.
10837 We have to live with this small inconsistency because the new
10838 construct also has a defining identifier, and there is no way
10839 to merge the two node structures.
10841 2017-01-13 Yannick Moy <moy@adacore.com>
10843 * inline.adb (Remove_Aspects_And_Pragmas): Add Unused to the

10848 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10850 * sem_ch3.adb (Resolve_Aspects): New procedure, subsidiary of
10851 Analyze_Declarations, to analyze and resolve the expressions of
10852 aspect specifications in the current declarative list, so that
10853 the expressions have proper entity and type info. This is needed
10854 for ASIS when there is no subsequent expansion to generate this
10855 semantic information.
10856 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
10857 original expression, to suppress cascaded errors when expression
10858 has been constant-folded.
10859 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
10860 ASIS mode, because there is no subsequent expansion to decorate
10863 2017-01-13 Yannick Moy <moy@adacore.com>
10865 * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
10866 New function to detect when a call may be inlined or not in
10868 (Expand_Inlined_Call): Ensure that a temporary
10869 is always created in the cases where a type conversion may be
10870 needed on an input parameter in GNATprove mode, so that GNATprove
10871 sees the check to perform.
10872 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
10873 when not applicable due to actual requiring type conversion
10874 with possible check but no temporary value can be copied for
10875 GNATprove to see the check.
