3601 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
3603 We used to have three different representations of the constant pool:
3604 the CPool structure, the tree_constant_pool, and the constructures
3605 used to build the Class object (which may need class and string
3606 constants) in compiled code. None were appropriate for compiling
3607 to .class files, so I did a major overhaul.
3609 First, the tree_constant_pool array was removed. Things were
3610 modified to the CPool structure in the JCF could be used.
3611 Second, a "capacity" field was added to the CPool, and functions
3612 written to search for a matching constant, adding one if not found.
3613 The code that generated the Class object was changed to use a CPool.
3614 The actual TREE_LISTs used to build the CONSTRUCTORs used for
3615 the static Class object are now only in build_constants_constructor.
3616 Finally, I wrote code which can generate a .class file (including its
3617 constant pool) from the RECORD_TYPE of a class. This is a big step
3618 on the way to compiling Java source into .class files.

3742 has a type. Propagate error_mark_node to node's type too. Promote
3743 method's call argument type and return error_mark_node if
3744 argument's completion didn't work. MODIFY_EXPR can have a WFL as a
3745 RHS. Fixed bug in the handling of bogus RHS of a fixed type. Now
3746 handle unary operator nodes.
3747 (build_assignment): Added comment.
3748 (print_int_node): New function.
3749 (patch_assignment): New second argument. New error handling. Use
3750 print_int_node. Handle references. Use can_cast_to_p to issue
3751 different error message according to the context and check upon
3752 the initialization of the RHS.

3809 (operator_string): Handle more case. Compacted source.
3810 (patch_binop): Changed function comment. Checking for
3811 uninitialized first operand takes the compound assignment into
3812 account and uses DECL_P. Checking for uninitialized second operand
3813 delayed to routine's end. Use macros to issue type bound error
3814 messages and issue messages on both operands if their types are
3815 different. Force fixed type into node. Handle all binary

3969 brace of the function. If the function has no body, use the
3970 location of the function's name. Override currently defined method
3971 name with the matching WFL so we can point redefinition errors
3972 using the location where the function's name was declared.

3987 type is incomplete, register a patch on its decl.
3988 (source_start_java_method): Rewritten. Define a new block for the

3994 completing the method start code.

3996 poplevel (already taken care of). Reinstall function's arguments

4000 code. Complement the second operand of the current COMPOUND_EXPR

4008 and invoke java_complete_tree on the effective method's body, if

4016 with the current arg list as a second argument. Inserted missing
4017 IDENTIFIER_POINTER when reporting an error on methods not found.
4018 (refine_accessible_methods_list): Don't retain constructors.
4019 (patch_arguments): Function removed.
4020 (java_complete_tree): Inserted comment before the function's
4021 code. New case for BLOCKs. Moved the WFL case a bit
4022 further. Complete function's arguments.
