5372 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
5374 We used to have three different representations of the constant pool:
5375 the CPool structure, the tree_constant_pool, and the constructures
5376 used to build the Class object (which may need class and string
5377 constants) in compiled code. None were appropriate for compiling
5378 to .class files, so I did a major overhaul.
5380 First, the tree_constant_pool array was removed. Things were
5381 modified to the CPool structure in the JCF could be used.
5382 Second, a "capacity" field was added to the CPool, and functions
5383 written to search for a matching constant, adding one if not found.
5384 The code that generated the Class object was changed to use a CPool.
5385 The actual TREE_LISTs used to build the CONSTRUCTORs used for
5386 the static Class object are now only in build_constants_constructor.
5387 Finally, I wrote code which can generate a .class file (including its
5388 constant pool) from the RECORD_TYPE of a class. This is a big step
5389 on the way to compiling Java source into .class files.
5391 * jcf-write.c: New file. Writes out a RECORD_TYPE as a .class file.

5434 identifiers. JDEPs are now part of the jdep_code enum.

5579 code.
5580 (operator_string): Handle more case. Compacted source.
5581 (patch_binop): Changed function comment. Checking for
5582 uninitialized first operand takes the compound assignment into
5583 account and uses DECL_P. Checking for uninitialized second operand
5584 delayed to routine's end. Use macros to issue type bound error
5585 messages and issue messages on both operands if their types are
5586 different. Force fixed type into node. Handle all binary
5587 operators.

5628 (java_complete_expand_methods): Don't process next method if
5629 completion of the previous one triggered errors.
5630 (java_complete_expand_method): Call source_end_java_method if no
5631 error were found during completion.
5632 (resolve_expression_name): Use IDENTIFIER_LOCAL_VALUE to retrieve

5634 error_mark_node when things aren't found.
5635 (patch_method_invocation_stmt): Return error_mark_node on failures.
5636 (patch_invoke): Removed unused local. Return the correct node.
5637 (java_complete_tree): Now returns a value. The BLOCK section binds
5638 local identifiers and the type of a BLOCK is now void. Assign the
5639 result of operand completion on COMPOUND_EXPR. Assign the
5640 encapsulated node of a WFL to the result of its completion, except
5641 when the node is an identifier. Now handle MODIFY_EXPR and several
5642 binary operators. Return error_mark_node on errors.

5680 * parse.y (source_start_java_method): Use TREE_SET_CODE instead
5681 of assigning to TREE_CODE. The latter method exploits a feature
5682 of GCC that is not ANSI compliant.

5686 * decl.c (pushdecl_force_head): New function.

5725 (compilation_unit:): Cosmetic on sub rule.
5726 (type_declaration:): Cosmetic on sub rules. Added an error rule.
5727 (variable_initializer:): Installed default rule on expression:.
5728 (method_declaration:): method_header: starts a new
5729 method. method_body: installs the function body, absorbs blocks
5730 emitted for temporary variable scopings, pops function's body block
5731 and merges function's last statement lineno in DECL_SOURCE_LINE.
5732 (method_body:): Installed default rules.
5733 (block:): Call enter_block when an opening brace is seen. Absorb
5734 scoping blocks and call exit_block when a closing brace is seen.

5737 (patch_stage): Added comment around definition.
5738 (method_header): Try to use first_ccb_indent1 as the first line of
5739 the method, so BP debug info are emitted at the first opening
5740 brace of the function. If the function has no body, use the
5741 location of the function's name. Override currently defined method
5742 name with the matching WFL so we can point redefinition errors
5743 using the location where the function's name was declared.
5744 (check_abstract_method_header): Interprets DECL_NAME as an
5745 identifier or as a WFL, accordingly.
5746 (java_complete_class): New cases for JDEP_TYPE and JDEP_PARM.

5755 new variable(s) if code has been already generated at that nesting
5756 level. Pinpoint redefinition errors using the variable id
5757 WFLs. Generate initialization code if necessary. If the variable
5758 type is incomplete, register a patch on its decl.
5759 (source_start_java_method): Rewritten. Define a new block for the
5760 function's parameters. Build parameter decl out of function's
5761 arguments and register them for a patch if their types are
5762 incomplete.
5763 (expand_start_java_method): Includes the part of
5764 source_start_java_method that was pushing the parameter decls and
5765 completing the method start code.

5767 poplevel (already taken care of). Reinstall function's arguments
5768 and get function's last line of code before calling
5769 expand_function_end.
5770 (java_method_add_stmt): New comment before the function's
5771 code. Complement the second operand of the current COMPOUND_EXPR

5774 zero when expanding a generated constructor.
5775 (java_complete_expand_method): Set start and end line numbers for
5776 a artificially generated constructor to one and manually call
5777 enter_block and exit_block when defining it. For all methods:
5778 expand function's start calling the new expand_start_java_method
5779 and invoke java_complete_tree on the effective method's body, if
5780 any.
5781 (resolve_expression_name): Now use lookup_name_in_blocks to search
5782 local variable decls and print out an error when variables are
5783 undefined.
5784 (patch_method_invocation_stmt): Inserted comment before the
5785 function's code.
5786 (lookup_method_invoke): Chain method's arguments using chainon
5787 with the current arg list as a second argument. Inserted missing
5788 IDENTIFIER_POINTER when reporting an error on methods not found.
5789 (refine_accessible_methods_list): Don't retain constructors.
5790 (patch_arguments): Function removed.
5791 (java_complete_tree): Inserted comment before the function's
5792 code. New case for BLOCKs. Moved the WFL case a bit
5793 further. Complete function's arguments.

5795 maybe_absorb_scoping_blocks): New functions.
