5513 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
5515 We used to have three different representations of the constant pool:
5516 the CPool structure, the tree_constant_pool, and the constructures
5517 used to build the Class object (which may need class and string
5518 constants) in compiled code. None were appropriate for compiling
5519 to .class files, so I did a major overhaul.
5521 First, the tree_constant_pool array was removed. Things were
5522 modified to the CPool structure in the JCF could be used.
5523 Second, a "capacity" field was added to the CPool, and functions
5524 written to search for a matching constant, adding one if not found.
5525 The code that generated the Class object was changed to use a CPool.
5526 The actual TREE_LISTs used to build the CONSTRUCTORs used for
5527 the static Class object are now only in build_constants_constructor.
5528 Finally, I wrote code which can generate a .class file (including its
5529 constant pool) from the RECORD_TYPE of a class. This is a big step
5530 on the way to compiling Java source into .class files.
5532 * jcf-write.c: New file. Writes out a RECORD_TYPE as a .class file.

5575 identifiers. JDEPs are now part of the jdep_code enum.

5931 (patch_arguments): Function removed.
5932 (java_complete_tree): Inserted comment before the function's
5933 code. New case for BLOCKs. Moved the WFL case a bit
