1723 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
1725 We used to have three different representations of the constant pool:
1726 the CPool structure, the tree_constant_pool, and the constructures
1727 used to build the Class object (which may need class and string
1728 constants) in compiled code. None were appropriate for compiling
1729 to .class files, so I did a major overhaul.
1731 First, the tree_constant_pool array was removed. Things were
1732 modified to the CPool structure in the JCF could be used.
1733 Second, a "capacity" field was added to the CPool, and functions
1734 written to search for a matching constant, adding one if not found.
1735 The code that generated the Class object was changed to use a CPool.
1736 The actual TREE_LISTs used to build the CONSTRUCTORs used for
1737 the static Class object are now only in build_constants_constructor.
1738 Finally, I wrote code which can generate a .class file (including its
1739 constant pool) from the RECORD_TYPE of a class. This is a big step
1740 on the way to compiling Java source into .class files.

1785 identifiers. JDEPs are now part of the jdep_code enum.

1935 delayed to routine's end. Use macros to issue type bound error
1936 messages and issue messages on both operands if their types are

2141 (patch_arguments): Function removed.
2142 (java_complete_tree): Inserted comment before the function's
2143 code. New case for BLOCKs. Moved the WFL case a bit
