4638 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
4640 We used to have three different representations of the constant pool:
4641 the CPool structure, the tree_constant_pool, and the constructures
4642 used to build the Class object (which may need class and string
4643 constants) in compiled code. None were appropriate for compiling
4644 to .class files, so I did a major overhaul.
4646 First, the tree_constant_pool array was removed. Things were
4647 modified to the CPool structure in the JCF could be used.
4648 Second, a "capacity" field was added to the CPool, and functions
4649 written to search for a matching constant, adding one if not found.
4650 The code that generated the Class object was changed to use a CPool.
4651 The actual TREE_LISTs used to build the CONSTRUCTORs used for
4652 the static Class object are now only in build_constants_constructor.
4653 Finally, I wrote code which can generate a .class file (including its
4654 constant pool) from the RECORD_TYPE of a class. This is a big step
4655 on the way to compiling Java source into .class files.

4768 with a promoted type.
4769 (declare_local_variables): Resolved non builtin types are promoted
4770 before being used to build a variable decl. Removed type patch
4771 posted on variable initialization statement.
4772 (source_start_java_method): Use build_decl_no_layout to build the
4773 decl of a parameter of incomplete type.

4779 has a type. Propagate error_mark_node to node's type too. Promote
4780 method's call argument type and return error_mark_node if
4781 argument's completion didn't work. MODIFY_EXPR can have a WFL as a
4782 RHS. Fixed bug in the handling of bogus RHS of a fixed type. Now
4783 handle unary operator nodes.
4784 (build_assignment): Added comment.
4785 (print_int_node): New function.
4786 (patch_assignment): New second argument. New error handling. Use
4787 print_int_node. Handle references. Use can_cast_to_p to issue

4846 (operator_string): Handle more case. Compacted source.
4847 (patch_binop): Changed function comment. Checking for
4848 uninitialized first operand takes the compound assignment into
4849 account and uses DECL_P. Checking for uninitialized second operand
4850 delayed to routine's end. Use macros to issue type bound error
4851 messages and issue messages on both operands if their types are
4852 different. Force fixed type into node. Handle all binary

5006 brace of the function. If the function has no body, use the
5007 location of the function's name. Override currently defined method
5008 name with the matching WFL so we can point redefinition errors
5009 using the location where the function's name was declared.

5024 type is incomplete, register a patch on its decl.
5025 (source_start_java_method): Rewritten. Define a new block for the

5053 with the current arg list as a second argument. Inserted missing
5054 IDENTIFIER_POINTER when reporting an error on methods not found.
5055 (refine_accessible_methods_list): Don't retain constructors.
5056 (patch_arguments): Function removed.
5057 (java_complete_tree): Inserted comment before the function's
5058 code. New case for BLOCKs. Moved the WFL case a bit
5059 further. Complete function's arguments.
