S/390: memset: Avoid overlapping MVC operands between iterations.

A memset with a value != 0 is currently implemented using the mvc
instruction propagating the first byte through 256 byte blocks.  While
for the first mvc the byte is written with a separate instruction
subsequent MVCs used the last byte of the previous 256 byte block.

Starting with z13 this causes a major performance degradation.  With
this patch we always set the first byte with an mvi or stc in order to
avoid the overlapping of the MVC operands between loop iterations.

On older machines this basically makes no measurable difference so the
patch enables the new behavior for all machine levels in order to make
sure that code built for older machine levels runs well when moved to
a z13.

failed, and enables GCC to optimize out the code that leads to the
warning.

df_ref_create_structure was inlined into the else part of
df_ref_record.  Due to the condition of the corresponding if, In the
else part, VRP deduced unsigned regno >= FIRST_PSEUDO_REGISTER.

In df_ref_create_structure, there's another regno variable,
initialized with the same expression and value as the caller's.  GCC
can tell as much, but this regno variable is signed.  It is used,
shifted right, to index a hard regset bit array within a path that
tests that this signed regno < FIRST_PSEUDO_REGISTER.

GCC warned about the possible out-of-range indexing into the hard
regset array.  It shouldn't, after all, the same regno can't possibly
be both < FIRST_PSEUDO_REGISTER and >= FIRST_PSEUDO_REGISTER, can it?

Well, the optimizers correctly decide it could, if it was a negative
int that, when converted to unsigned, became larger than
FIRST_PSEUDO_REGISTER.  But GCC doesn't know regno can't be negative,
so the test could not be optimize out.  What's more, given the
constraints, VRP correctly concluded the hard regset array would
always be indexed by a value way outside the array index range.

This patch changes the inlined regno to unsigned, like the caller's,
so that we can now tell the conditions can't both hold, so we optimize
out the path containing the would-be out-of-range array indexing.

* df-scan.c (df_ref_create_structure): Make regno unsigned,
to match the caller.

[-fcompare-debug] find jump before debug insns in expand

A debug insn after the final jump of a basic block may cause the

7 years agoMake MIPS soft-fp preserve NaN payloads for NAN2008.
Joseph Myers [Wed, 4 Jan 2017 17:06:33 +0000 (17:06 +0000)]
Make MIPS soft-fp preserve NaN payloads for NAN2008.

The MIPS sfp-machine.h has an _FP_CHOOSENAN implementation which
emulates hardware semantics of not preserving signaling NaN payloads
for an operation with two NaN arguments (although that doesn't suffice
to avoid sNaN payload preservation in any case with just one NaN
argument).

However, those are only hardware semantics in the legacy NaN case; in
the NAN2008 case, the architecture documentation says hardware
preserves payloads in such cases.  Furthermore, this implementation
assumes legacy NaN semantics, so in the NAN2008 case the
implementation actually has the effect of preserving sNaN payloads but
not preserving qNaN payloads, when both should be preserved.

This patch fixes the code just to copy from the first argument (at the
level of libgcc, it's not meaningful which argument is the first and
which is the second).

Tested for mips64-linux-gnu (soft float, NAN2008) with the glibc math/
tests.

7 years agoDWARF: add DW_AT_encoding attributes for DW_TAG_enumeration_type DIEs
Pierre-Marie de Rodat [Tue, 3 Jan 2017 08:54:57 +0000 (08:54 +0000)]
DWARF: add DW_AT_encoding attributes for DW_TAG_enumeration_type DIEs

Currently, the DWARF description does not specify the signedness of the
representation of enumeration types.  This is a problem in some
contexts where DWARF consumers need to determine if value X is greater
than value Y.

For instance in Ada:

    type Enum_Type is ( A, B, C, D);
    for Enum_Type use (-1, 0, 1, 2);

    type Rec_Type (E : Enum_Type) is record
       when A .. B => null;
       when others => B : Booleann;
    end record;

The above can be described in DWARF the following way:

    DW_TAG_enumeration_type(Enum_Type)
    | DW_AT_byte_size: 1
      DW_TAG_enumerator(A)
      | DW_AT_const_value: -1
      DW_TAG_enumerator(B)
      | DW_AT_const_value: 0
      DW_TAG_enumerator(C)
      | DW_AT_const_value: 1
      DW_TAG_enumerator(D)
      | DW_AT_const_value: 2

    DW_TAG_structure_type(Rec_Type)
      DW_TAG_member(E)
      | DW_AT_type: <Enum_Type>
      DW_TAG_variant_part
      | DW_AT_discr: <E>
        DW_TAG_variant
        | DW_AT_discr_list: DW_DSC_range 0x7f 0
        DW_TAG_variant
        | DW_TAG_member(b)

DWARF consumers need to know that enumerators (A, B, C and D) are signed
in order to determine the set of E values for which Rec_Type has a B
field.  In practice, they need to know how to interpret the 0x7f LEB128
number above (-1, not 127).

When in non-strict DWARF mode, this patch adds a DW_AT_encoding
attribute to generated DW_TAG_enumeration_type DIEs to make this
signedness explicit.

gcc/

* dwarf2out.c (gen_enumeration_type_die): When
-gno-strict-dwarf, add a DW_AT_encoding attribute.

7 years agoPR 78534 Change character length from int to size_t
Janne Blomqvist [Tue, 3 Jan 2017 07:04:01 +0000 (09:04 +0200)]
PR 78534 Change character length from int to size_t

In order to handle large character lengths on (L)LP64 targets, switch
the GFortran character length from an int to a size_t.

This is an ABI change, as procedures with character arguments take
hidden arguments with the character length.

I also changed the _size member in vtables from int to size_t, as
there were some cases where character lengths and sizes were
apparently mixed up and caused regressions otherwise. Although I
haven't tested, this might enable very large derived types as well.

Also, as there are some places in the frontend were negative character
lengths are used as special flag values, in the frontend the character
length is handled as a signed variable of the same size as a size_t,
although in the runtime library it really is size_t.

I haven't changed the character length variables for the co-array
intrinsics, as this is something that may need to be synchronized with
OpenCoarrays.

This is v3 of the patch. All the issues pointed out by FX's review of
v2 have been fixed. In particular, there are now new functions
gfc_mpz_get_hwi and gfc_mpz_set_hwi, similar to the GMP functions
mpz_get_si and mpz_set_si, except that they get/set a HOST_WIDE_INT
instead of a long value. Similarly, gfc_get_int_expr now takes a
HOST_WIDE_INT instead of a long, gfc_extract_long is replaced by
gfc_extract_hwi. Also, the preliminary work to handle
gfc_charlen_type_node being unsigned has been removed.

Regtested on x86_64-pc-linux-gnu.
