4087 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
4089 We used to have three different representations of the constant pool:
4090 the CPool structure, the tree_constant_pool, and the constructures
4091 used to build the Class object (which may need class and string
4092 constants) in compiled code. None were appropriate for compiling
4093 to .class files, so I did a major overhaul.
4095 First, the tree_constant_pool array was removed. Things were
4096 modified to the CPool structure in the JCF could be used.
4097 Second, a "capacity" field was added to the CPool, and functions
4098 written to search for a matching constant, adding one if not found.
4099 The code that generated the Class object was changed to use a CPool.
4100 The actual TREE_LISTs used to build the CONSTRUCTORs used for
4101 the static Class object are now only in build_constants_constructor.
4102 Finally, I wrote code which can generate a .class file (including its
4103 constant pool) from the RECORD_TYPE of a class. This is a big step
4104 on the way to compiling Java source into .class files.

4149 identifiers. JDEPs are now part of the jdep_code enum.

4299 delayed to routine's end. Use macros to issue type bound error
4300 messages and issue messages on both operands if their types are
4301 different. Force fixed type into node. Handle all binary

4458 using the location where the function's name was declared.

4473 type is incomplete, register a patch on its decl.

4502 with the current arg list as a second argument. Inserted missing
4503 IDENTIFIER_POINTER when reporting an error on methods not found.
4504 (refine_accessible_methods_list): Don't retain constructors.
4505 (patch_arguments): Function removed.
4506 (java_complete_tree): Inserted comment before the function's
4507 code. New case for BLOCKs. Moved the WFL case a bit
4508 further. Complete function's arguments.
