4577 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
4579 We used to have three different representations of the constant pool:
4580 the CPool structure, the tree_constant_pool, and the constructures
4581 used to build the Class object (which may need class and string
4582 constants) in compiled code. None were appropriate for compiling
4583 to .class files, so I did a major overhaul.
4585 First, the tree_constant_pool array was removed. Things were
4586 modified to the CPool structure in the JCF could be used.
4587 Second, a "capacity" field was added to the CPool, and functions
4588 written to search for a matching constant, adding one if not found.
4589 The code that generated the Class object was changed to use a CPool.
4590 The actual TREE_LISTs used to build the CONSTRUCTORs used for
4591 the static Class object are now only in build_constants_constructor.
4592 Finally, I wrote code which can generate a .class file (including its
4593 constant pool) from the RECORD_TYPE of a class. This is a big step
4594 on the way to compiling Java source into .class files.

4639 identifiers. JDEPs are now part of the jdep_code enum.

4785 (operator_string): Handle more case. Compacted source.
4786 (patch_binop): Changed function comment. Checking for
4787 uninitialized first operand takes the compound assignment into
4788 account and uses DECL_P. Checking for uninitialized second operand
4789 delayed to routine's end. Use macros to issue type bound error
4790 messages and issue messages on both operands if their types are
4791 different. Force fixed type into node. Handle all binary

4833 (java_complete_expand_methods): Don't process next method if
4834 completion of the previous one triggered errors.

4844 result of operand completion on COMPOUND_EXPR. Assign the
4845 encapsulated node of a WFL to the result of its completion, except
4846 when the node is an identifier. Now handle MODIFY_EXPR and several

4885 * parse.y (source_start_java_method): Use TREE_SET_CODE instead
4886 of assigning to TREE_CODE. The latter method exploits a feature

4933 (method_declaration:): method_header: starts a new
4934 method. method_body: installs the function body, absorbs blocks

4936 and merges function's last statement lineno in DECL_SOURCE_LINE.
4937 (method_body:): Installed default rules.

4939 scoping blocks and call exit_block when a closing brace is seen.

4942 (patch_stage): Added comment around definition.
4943 (method_header): Try to use first_ccb_indent1 as the first line of
4944 the method, so BP debug info are emitted at the first opening
4945 brace of the function. If the function has no body, use the
4946 location of the function's name. Override currently defined method
4947 name with the matching WFL so we can point redefinition errors
4948 using the location where the function's name was declared.

4963 type is incomplete, register a patch on its decl.
4964 (source_start_java_method): Rewritten. Define a new block for the
4965 function's parameters. Build parameter decl out of function's
4966 arguments and register them for a patch if their types are

4970 completing the method start code.

4972 poplevel (already taken care of). Reinstall function's arguments
4973 and get function's last line of code before calling

4976 code. Complement the second operand of the current COMPOUND_EXPR

4984 and invoke java_complete_tree on the effective method's body, if
4986 (resolve_expression_name): Now use lookup_name_in_blocks to search
4987 local variable decls and print out an error when variables are
4989 (patch_method_invocation_stmt): Inserted comment before the
4991 (lookup_method_invoke): Chain method's arguments using chainon
4992 with the current arg list as a second argument. Inserted missing
4993 IDENTIFIER_POINTER when reporting an error on methods not found.
4994 (refine_accessible_methods_list): Don't retain constructors.
4995 (patch_arguments): Function removed.
4996 (java_complete_tree): Inserted comment before the function's
4997 code. New case for BLOCKs. Moved the WFL case a bit
4998 further. Complete function's arguments.
