4999 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
5001 We used to have three different representations of the constant pool:
5002 the CPool structure, the tree_constant_pool, and the constructures
5003 used to build the Class object (which may need class and string
5004 constants) in compiled code. None were appropriate for compiling
5005 to .class files, so I did a major overhaul.
5007 First, the tree_constant_pool array was removed. Things were
5008 modified to the CPool structure in the JCF could be used.
5009 Second, a "capacity" field was added to the CPool, and functions
5010 written to search for a matching constant, adding one if not found.
5011 The code that generated the Class object was changed to use a CPool.
5012 The actual TREE_LISTs used to build the CONSTRUCTORs used for
5013 the static Class object are now only in build_constants_constructor.
5014 Finally, I wrote code which can generate a .class file (including its
5015 constant pool) from the RECORD_TYPE of a class. This is a big step
5016 on the way to compiling Java source into .class files.

5061 identifiers. JDEPs are now part of the jdep_code enum.

5417 (patch_arguments): Function removed.
5418 (java_complete_tree): Inserted comment before the function's
5419 code. New case for BLOCKs. Moved the WFL case a bit
