4962 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
4964 We used to have three different representations of the constant pool:
4965 the CPool structure, the tree_constant_pool, and the constructures
4966 used to build the Class object (which may need class and string
4967 constants) in compiled code. None were appropriate for compiling
4968 to .class files, so I did a major overhaul.
4970 First, the tree_constant_pool array was removed. Things were
4971 modified to the CPool structure in the JCF could be used.
4972 Second, a "capacity" field was added to the CPool, and functions
4973 written to search for a matching constant, adding one if not found.
4974 The code that generated the Class object was changed to use a CPool.
4975 The actual TREE_LISTs used to build the CONSTRUCTORs used for
4976 the static Class object are now only in build_constants_constructor.
4977 Finally, I wrote code which can generate a .class file (including its
4978 constant pool) from the RECORD_TYPE of a class. This is a big step
4979 on the way to compiling Java source into .class files.
4981 * jcf-write.c: New file. Writes out a RECORD_TYPE as a .class file.

5024 identifiers. JDEPs are now part of the jdep_code enum.
5025 (typedef struct jdep): Now use enum jdep_code or int, depending on
5026 availability. Both are narrowed down to an 8 bits bitfield.
5027 (CALL_EXPR_PRIMARY): Fixed comment.

5103 has a type. Propagate error_mark_node to node's type too. Promote
5104 method's call argument type and return error_mark_node if
5105 argument's completion didn't work. MODIFY_EXPR can have a WFL as a
5106 RHS. Fixed bug in the handling of bogus RHS of a fixed type. Now

5175 messages and issue messages on both operands if their types are
5176 different. Force fixed type into node. Handle all binary

5380 (patch_arguments): Function removed.
5381 (java_complete_tree): Inserted comment before the function's
5382 code. New case for BLOCKs. Moved the WFL case a bit
