5011 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
5013 We used to have three different representations of the constant pool:
5014 the CPool structure, the tree_constant_pool, and the constructures
5015 used to build the Class object (which may need class and string
5016 constants) in compiled code. None were appropriate for compiling
5017 to .class files, so I did a major overhaul.
5019 First, the tree_constant_pool array was removed. Things were
5020 modified to the CPool structure in the JCF could be used.
5021 Second, a "capacity" field was added to the CPool, and functions
5022 written to search for a matching constant, adding one if not found.
5023 The code that generated the Class object was changed to use a CPool.
5024 The actual TREE_LISTs used to build the CONSTRUCTORs used for
5025 the static Class object are now only in build_constants_constructor.
5026 Finally, I wrote code which can generate a .class file (including its
5027 constant pool) from the RECORD_TYPE of a class. This is a big step
5028 on the way to compiling Java source into .class files.

5073 identifiers. JDEPs are now part of the jdep_code enum.

5429 (patch_arguments): Function removed.
5430 (java_complete_tree): Inserted comment before the function's
5431 code. New case for BLOCKs. Moved the WFL case a bit
