5367Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
5368
5369 We used to have three different representations of the constant pool:
5370 the CPool structure, the tree_constant_pool, and the constructures
5371 used to build the Class object (which may need class and string
5372 constants) in compiled code. None were appropriate for compiling
5373 to .class files, so I did a major overhaul.
5374
5375 First, the tree_constant_pool array was removed. Things were
5376 modified to the CPool structure in the JCF could be used.
5377 Second, a "capacity" field was added to the CPool, and functions
5378 written to search for a matching constant, adding one if not found.
5379 The code that generated the Class object was changed to use a CPool.
5380 The actual TREE_LISTs used to build the CONSTRUCTORs used for
5381 the static Class object are now only in build_constants_constructor.
5382 Finally, I wrote code which can generate a .class file (including its
5383 constant pool) from the RECORD_TYPE of a class. This is a big step
5384 on the way to compiling Java source into .class files.

5420
5421 * expr.c (build_java_arrayaccess): Generate more efficient array
5422 bounds checking, by using unsigned compare.
5423
5424 * expr.c (expand_invoke): Re-arrange error checks to make more robust.
5425
5426Wed Jun 10 17:34:42 1998 Alexandre Petit-Bianco <apbianco@cygnus.com>
5427
5428 * parse.h: New comment on the handling of unresolved type
5429 identifiers. JDEPs are now part of the jdep_code enum.
5430 (typedef struct jdep): Now use enum jdep_code or int, depending on
5431 availability. Both are narrowed down to an 8 bits bitfield.
5432 (CALL_EXPR_PRIMARY): Fixed comment.
5433

5512 handle unary operator nodes.
5513 (build_assignment): Added comment.
5514 (print_int_node): New function.
5515 (patch_assignment): New second argument. New error handling. Use

5543 Java (source) name, not signature.
5544 Set TYPE_ALIGN to (at least) that of element_type.
5545
5546Tue Jun 2 15:19:19 1998 Per Bothner <bothner@cygnus.com>

5574 code.
5575 (operator_string): Handle more case. Compacted source.
5576 (patch_binop): Changed function comment. Checking for
5577 uninitialized first operand takes the compound assignment into
5578 account and uses DECL_P. Checking for uninitialized second operand
5579 delayed to routine's end. Use macros to issue type bound error
5580 messages and issue messages on both operands if their types are
5581 different. Force fixed type into node. Handle all binary
5582 operators.
5583
5584Wed May 27 10:30:31 1998 Alexandre Petit-Bianco <apbianco@cygnus.com>

5628 locals declaratilon. Handle names found within a class. Return
5629 error_mark_node when things aren't found.
5630 (patch_method_invocation_stmt): Return error_mark_node on failures.
5631 (patch_invoke): Removed unused local. Return the correct node.
5632 (java_complete_tree): Now returns a value. The BLOCK section binds
5633 local identifiers and the type of a BLOCK is now void. Assign the
5634 result of operand completion on COMPOUND_EXPR. Assign the
5635 encapsulated node of a WFL to the result of its completion, except
5636 when the node is an identifier. Now handle MODIFY_EXPR and several
5637 binary operators. Return error_mark_node on errors.

5674
5675 * parse.y (source_start_java_method): Use TREE_SET_CODE instead
5676 of assigning to TREE_CODE. The latter method exploits a feature
5677 of GCC that is not ANSI compliant.
5678
5679Thu May 12 13:44:27 1998 Alexandre Petit-Bianco <apbianco@cygnus.com>

5700 * parse.h: Now includes lex.h
5701 (SOURCE_FRONTEND_DEBUG): Macro redefined to conditionally use
5702 printf if the macro is defined.

5717 BOOL_LIT_TK, CHAR_LIT_TK, STRING_LIT_TK, NULL_TK, VOID_TK): Rules
5718 tagged <node>
5719 (SOURCE_FRONTEND_DEBUG): Used as macro accepting varargs.
5720 (compilation_unit:): Cosmetic on sub rule.
5721 (type_declaration:): Cosmetic on sub rules. Added an error rule.
5722 (variable_initializer:): Installed default rule on expression:.
5723 (method_declaration:): method_header: starts a new
5724 method. method_body: installs the function body, absorbs blocks
5725 emitted for temporary variable scopings, pops function's body block
5726 and merges function's last statement lineno in DECL_SOURCE_LINE.
5727 (method_body:): Installed default rules.
5728 (block:): Call enter_block when an opening brace is seen. Absorb
5729 scoping blocks and call exit_block when a closing brace is seen.

5732 (patch_stage): Added comment around definition.
5733 (method_header): Try to use first_ccb_indent1 as the first line of
5734 the method, so BP debug info are emitted at the first opening
5735 brace of the function. If the function has no body, use the
5736 location of the function's name. Override currently defined method
5737 name with the matching WFL so we can point redefinition errors
5738 using the location where the function's name was declared.
5739 (check_abstract_method_header): Interprets DECL_NAME as an
5740 identifier or as a WFL, accordingly.
5741 (java_complete_class): New cases for JDEP_TYPE and JDEP_PARM.

5750 new variable(s) if code has been already generated at that nesting
5751 level. Pinpoint redefinition errors using the variable id
5752 WFLs. Generate initialization code if necessary. If the variable
5753 type is incomplete, register a patch on its decl.
5754 (source_start_java_method): Rewritten. Define a new block for the
5755 function's parameters. Build parameter decl out of function's
5756 arguments and register them for a patch if their types are
5757 incomplete.
5758 (expand_start_java_method): Includes the part of
5759 source_start_java_method that was pushing the parameter decls and
5760 completing the method start code.
5761 (source_end_java_method): Removed call the expand_end_bindings and
5762 poplevel (already taken care of). Reinstall function's arguments
5763 and get function's last line of code before calling
5764 expand_function_end.
5765 (java_method_add_stmt): New comment before the function's
5766 code. Complement the second operand of the current COMPOUND_EXPR
5767 if necessary.

5769 zero when expanding a generated constructor.
5770 (java_complete_expand_method): Set start and end line numbers for
5771 a artificially generated constructor to one and manually call
5772 enter_block and exit_block when defining it. For all methods:
5773 expand function's start calling the new expand_start_java_method
5774 and invoke java_complete_tree on the effective method's body, if
5775 any.
5776 (resolve_expression_name): Now use lookup_name_in_blocks to search
5777 local variable decls and print out an error when variables are
5778 undefined.
5779 (patch_method_invocation_stmt): Inserted comment before the
5780 function's code.
5781 (lookup_method_invoke): Chain method's arguments using chainon
5782 with the current arg list as a second argument. Inserted missing
5783 IDENTIFIER_POINTER when reporting an error on methods not found.
