3572 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
3574 We used to have three different representations of the constant pool:
3575 the CPool structure, the tree_constant_pool, and the constructures
3576 used to build the Class object (which may need class and string
3577 constants) in compiled code. None were appropriate for compiling
3578 to .class files, so I did a major overhaul.
3580 First, the tree_constant_pool array was removed. Things were
3581 modified to the CPool structure in the JCF could be used.
3582 Second, a "capacity" field was added to the CPool, and functions
3583 written to search for a matching constant, adding one if not found.
3584 The code that generated the Class object was changed to use a CPool.
3585 The actual TREE_LISTs used to build the CONSTRUCTORs used for
3586 the static Class object are now only in build_constants_constructor.
3587 Finally, I wrote code which can generate a .class file (including its
3588 constant pool) from the RECORD_TYPE of a class. This is a big step
3589 on the way to compiling Java source into .class files.

3634 identifiers. JDEPs are now part of the jdep_code enum.

3782 uninitialized first operand takes the compound assignment into
3783 account and uses DECL_P. Checking for uninitialized second operand
3784 delayed to routine's end. Use macros to issue type bound error
3785 messages and issue messages on both operands if their types are
3786 different. Force fixed type into node. Handle all binary

3829 completion of the previous one triggered errors.

3880 * parse.y (source_start_java_method): Use TREE_SET_CODE instead
3881 of assigning to TREE_CODE. The latter method exploits a feature

3940 brace of the function. If the function has no body, use the
3941 location of the function's name. Override currently defined method
3942 name with the matching WFL so we can point redefinition errors
3943 using the location where the function's name was declared.

3958 type is incomplete, register a patch on its decl.
3959 (source_start_java_method): Rewritten. Define a new block for the

3965 completing the method start code.

3967 poplevel (already taken care of). Reinstall function's arguments
3968 and get function's last line of code before calling

3971 code. Complement the second operand of the current COMPOUND_EXPR

3979 and invoke java_complete_tree on the effective method's body, if

3982 local variable decls and print out an error when variables are
3984 (patch_method_invocation_stmt): Inserted comment before the

3987 with the current arg list as a second argument. Inserted missing
3988 IDENTIFIER_POINTER when reporting an error on methods not found.
3989 (refine_accessible_methods_list): Don't retain constructors.
3990 (patch_arguments): Function removed.
3991 (java_complete_tree): Inserted comment before the function's
3992 code. New case for BLOCKs. Moved the WFL case a bit
3993 further. Complete function's arguments.
