5122 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
5124 We used to have three different representations of the constant pool:
5125 the CPool structure, the tree_constant_pool, and the constructures
5126 used to build the Class object (which may need class and string
5127 constants) in compiled code. None were appropriate for compiling
5128 to .class files, so I did a major overhaul.
5130 First, the tree_constant_pool array was removed. Things were
5131 modified to the CPool structure in the JCF could be used.
5132 Second, a "capacity" field was added to the CPool, and functions
5133 written to search for a matching constant, adding one if not found.
5134 The code that generated the Class object was changed to use a CPool.
5135 The actual TREE_LISTs used to build the CONSTRUCTORs used for
5136 the static Class object are now only in build_constants_constructor.
5137 Finally, I wrote code which can generate a .class file (including its
5138 constant pool) from the RECORD_TYPE of a class. This is a big step
5139 on the way to compiling Java source into .class files.

5184 identifiers. JDEPs are now part of the jdep_code enum.

5332 uninitialized first operand takes the compound assignment into
5333 account and uses DECL_P. Checking for uninitialized second operand
5334 delayed to routine's end. Use macros to issue type bound error
5335 messages and issue messages on both operands if their types are
5336 different. Force fixed type into node. Handle all binary

5490 brace of the function. If the function has no body, use the
5491 location of the function's name. Override currently defined method
5492 name with the matching WFL so we can point redefinition errors
5493 using the location where the function's name was declared.

5508 type is incomplete, register a patch on its decl.

5517 poplevel (already taken care of). Reinstall function's arguments

5537 with the current arg list as a second argument. Inserted missing
5538 IDENTIFIER_POINTER when reporting an error on methods not found.
5539 (refine_accessible_methods_list): Don't retain constructors.
5540 (patch_arguments): Function removed.
5541 (java_complete_tree): Inserted comment before the function's
5542 code. New case for BLOCKs. Moved the WFL case a bit
5543 further. Complete function's arguments.
