4867 new flag. It's no longer necessary to access the selected method
4868 as the value of a tree list. Handle constructor invocation.

4870 methods. Insert call to new as the first argument of the

5205 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
5207 We used to have three different representations of the constant pool:
5208 the CPool structure, the tree_constant_pool, and the constructures
5209 used to build the Class object (which may need class and string
5210 constants) in compiled code. None were appropriate for compiling
5211 to .class files, so I did a major overhaul.
5213 First, the tree_constant_pool array was removed. Things were
5214 modified to the CPool structure in the JCF could be used.
5215 Second, a "capacity" field was added to the CPool, and functions
5216 written to search for a matching constant, adding one if not found.
5217 The code that generated the Class object was changed to use a CPool.
5218 The actual TREE_LISTs used to build the CONSTRUCTORs used for
5219 the static Class object are now only in build_constants_constructor.
5220 Finally, I wrote code which can generate a .class file (including its
5221 constant pool) from the RECORD_TYPE of a class. This is a big step
5222 on the way to compiling Java source into .class files.
5224 * jcf-write.c: New file. Writes out a RECORD_TYPE as a .class file.

5335 with a promoted type.
5336 (declare_local_variables): Resolved non builtin types are promoted
5337 before being used to build a variable decl. Removed type patch
5338 posted on variable initialization statement.
5339 (source_start_java_method): Use build_decl_no_layout to build the

5348 argument's completion didn't work. MODIFY_EXPR can have a WFL as a
5349 RHS. Fixed bug in the handling of bogus RHS of a fixed type. Now
5350 handle unary operator nodes.
5351 (build_assignment): Added comment.
5352 (print_int_node): New function.
5353 (patch_assignment): New second argument. New error handling. Use
5354 print_int_node. Handle references. Use can_cast_to_p to issue

5413 (operator_string): Handle more case. Compacted source.
5414 (patch_binop): Changed function comment. Checking for
5415 uninitialized first operand takes the compound assignment into
5416 account and uses DECL_P. Checking for uninitialized second operand
5417 delayed to routine's end. Use macros to issue type bound error
5418 messages and issue messages on both operands if their types are
5419 different. Force fixed type into node. Handle all binary

5462 completion of the previous one triggered errors.

5472 result of operand completion on COMPOUND_EXPR. Assign the
5473 encapsulated node of a WFL to the result of its completion, except
5474 when the node is an identifier. Now handle MODIFY_EXPR and several

5513 * parse.y (source_start_java_method): Use TREE_SET_CODE instead
5514 of assigning to TREE_CODE. The latter method exploits a feature

5560 (variable_initializer:): Installed default rule on expression:.
5561 (method_declaration:): method_header: starts a new
5562 method. method_body: installs the function body, absorbs blocks
5563 emitted for temporary variable scopings, pops function's body block
5564 and merges function's last statement lineno in DECL_SOURCE_LINE.
5565 (method_body:): Installed default rules.

5567 scoping blocks and call exit_block when a closing brace is seen.

5570 (patch_stage): Added comment around definition.
5571 (method_header): Try to use first_ccb_indent1 as the first line of
5572 the method, so BP debug info are emitted at the first opening
5573 brace of the function. If the function has no body, use the
5574 location of the function's name. Override currently defined method
5575 name with the matching WFL so we can point redefinition errors
5576 using the location where the function's name was declared.

5578 identifier or as a WFL, accordingly.
5579 (java_complete_class): New cases for JDEP_TYPE and JDEP_PARM.

5588 new variable(s) if code has been already generated at that nesting
5589 level. Pinpoint redefinition errors using the variable id
5590 WFLs. Generate initialization code if necessary. If the variable
5591 type is incomplete, register a patch on its decl.
5592 (source_start_java_method): Rewritten. Define a new block for the
5593 function's parameters. Build parameter decl out of function's
5594 arguments and register them for a patch if their types are

5597 source_start_java_method that was pushing the parameter decls and
5598 completing the method start code.

5600 poplevel (already taken care of). Reinstall function's arguments
5601 and get function's last line of code before calling

5604 code. Complement the second operand of the current COMPOUND_EXPR

5612 and invoke java_complete_tree on the effective method's body, if
5614 (resolve_expression_name): Now use lookup_name_in_blocks to search
5615 local variable decls and print out an error when variables are
5617 (patch_method_invocation_stmt): Inserted comment before the
5619 (lookup_method_invoke): Chain method's arguments using chainon
5620 with the current arg list as a second argument. Inserted missing
5621 IDENTIFIER_POINTER when reporting an error on methods not found.
5622 (refine_accessible_methods_list): Don't retain constructors.
5623 (patch_arguments): Function removed.
5624 (java_complete_tree): Inserted comment before the function's
5625 code. New case for BLOCKs. Moved the WFL case a bit
5626 further. Complete function's arguments.
