4839 message. type_wfl assigned to unresolved type and used to register
4840 incomplete type. Build a WFL around the variable initialization
4841 statement so that debug info can be generated on it.

4853 as qualified method invocation. Call lookup_method_invoke with its
4854 new flag. It's no longer necessary to access the selected method
4855 as the value of a tree list. Handle constructor invocation.

4857 methods. Insert call to new as the first argument of the

4861 method is a constructor.

4874 (patch_assignment): LHS can be a field access expression. When
4875 dealing with reference, lhs_type is the promoted type of the
4876 rhs_type, not the RHS. Use not_initialized_as_it_should_p where

5192 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
5194 We used to have three different representations of the constant pool:
5195 the CPool structure, the tree_constant_pool, and the constructures
5196 used to build the Class object (which may need class and string
5197 constants) in compiled code. None were appropriate for compiling
5198 to .class files, so I did a major overhaul.
5200 First, the tree_constant_pool array was removed. Things were
5201 modified to the CPool structure in the JCF could be used.
5202 Second, a "capacity" field was added to the CPool, and functions
5203 written to search for a matching constant, adding one if not found.
5204 The code that generated the Class object was changed to use a CPool.
5205 The actual TREE_LISTs used to build the CONSTRUCTORs used for
5206 the static Class object are now only in build_constants_constructor.
5207 Finally, I wrote code which can generate a .class file (including its
5208 constant pool) from the RECORD_TYPE of a class. This is a big step
5209 on the way to compiling Java source into .class files.
5211 * jcf-write.c: New file. Writes out a RECORD_TYPE as a .class file.

5336 RHS. Fixed bug in the handling of bogus RHS of a fixed type. Now
5337 handle unary operator nodes.
5338 (build_assignment): Added comment.
5339 (print_int_node): New function.
5340 (patch_assignment): New second argument. New error handling. Use

5402 uninitialized first operand takes the compound assignment into
5403 account and uses DECL_P. Checking for uninitialized second operand
5404 delayed to routine's end. Use macros to issue type bound error
5405 messages and issue messages on both operands if their types are
5406 different. Force fixed type into node. Handle all binary

5558 (method_header): Try to use first_ccb_indent1 as the first line of

5560 brace of the function. If the function has no body, use the
5561 location of the function's name. Override currently defined method
5562 name with the matching WFL so we can point redefinition errors
5563 using the location where the function's name was declared.

5578 type is incomplete, register a patch on its decl.
5579 (source_start_java_method): Rewritten. Define a new block for the
5580 function's parameters. Build parameter decl out of function's
5581 arguments and register them for a patch if their types are

5585 completing the method start code.

5587 poplevel (already taken care of). Reinstall function's arguments

5607 with the current arg list as a second argument. Inserted missing
5608 IDENTIFIER_POINTER when reporting an error on methods not found.
5609 (refine_accessible_methods_list): Don't retain constructors.
5610 (patch_arguments): Function removed.
5611 (java_complete_tree): Inserted comment before the function's
5612 code. New case for BLOCKs. Moved the WFL case a bit
5613 further. Complete function's arguments.
