4287 expression produced by make_qualified_name.
4288 (java_complete_tree): Promote type when function's argument are

4290 the assignment to discover further errors if RHS is a expression
4291 name that fails to evaluate. Declare LHS initialized even though
4292 the assignment failed. Don't use the location variable and removed
4293 extra argument in patch function calls. Now handle the ARRAY_REF
4294 case and build internal string representation when STRING_CSTs are

4359 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
4361 We used to have three different representations of the constant pool:
4362 the CPool structure, the tree_constant_pool, and the constructures
4363 used to build the Class object (which may need class and string
4364 constants) in compiled code. None were appropriate for compiling
4365 to .class files, so I did a major overhaul.
4367 First, the tree_constant_pool array was removed. Things were
4368 modified to the CPool structure in the JCF could be used.
4369 Second, a "capacity" field was added to the CPool, and functions
4370 written to search for a matching constant, adding one if not found.
4371 The code that generated the Class object was changed to use a CPool.
4372 The actual TREE_LISTs used to build the CONSTRUCTORs used for
4373 the static Class object are now only in build_constants_constructor.
4374 Finally, I wrote code which can generate a .class file (including its
4375 constant pool) from the RECORD_TYPE of a class. This is a big step
4376 on the way to compiling Java source into .class files.
4378 * jcf-write.c: New file. Writes out a RECORD_TYPE as a .class file.
4379 * Makefile.in (JAVA_OBJS): Added jcf-write.o.

4394 * constants.c (build_constants_constructor): Use new outgoing_cpool.

4421 identifiers. JDEPs are now part of the jdep_code enum.
4422 (typedef struct jdep): Now use enum jdep_code or int, depending on
4423 availability. Both are narrowed down to an 8 bits bitfield.
4424 (CALL_EXPR_PRIMARY): Fixed comment.

4500 has a type. Propagate error_mark_node to node's type too. Promote
4501 method's call argument type and return error_mark_node if
4502 argument's completion didn't work. MODIFY_EXPR can have a WFL as a
4503 RHS. Fixed bug in the handling of bogus RHS of a fixed type. Now
4504 handle unary operator nodes.
4505 (build_assignment): Added comment.
4506 (print_int_node): New function.
4507 (patch_assignment): New second argument. New error handling. Use
4508 print_int_node. Handle references. Use can_cast_to_p to issue

4511 (can_cast_to_p, valid_ref_assignconv_cast_p): New functions.
4512 (operator_string): Handle more operators.
4513 (patch_binop): No longer use a function static

4567 (operator_string): Handle more case. Compacted source.
4568 (patch_binop): Changed function comment. Checking for
4569 uninitialized first operand takes the compound assignment into
4570 account and uses DECL_P. Checking for uninitialized second operand
4571 delayed to routine's end. Use macros to issue type bound error
4572 messages and issue messages on both operands if their types are
4573 different. Force fixed type into node. Handle all binary

4714 (variable_initializer:): Installed default rule on expression:.
4715 (method_declaration:): method_header: starts a new
4716 method. method_body: installs the function body, absorbs blocks
4717 emitted for temporary variable scopings, pops function's body block
4718 and merges function's last statement lineno in DECL_SOURCE_LINE.
4719 (method_body:): Installed default rules.

4725 (method_header): Try to use first_ccb_indent1 as the first line of

4729 name with the matching WFL so we can point redefinition errors
4730 using the location where the function's name was declared.

4742 new variable(s) if code has been already generated at that nesting
4743 level. Pinpoint redefinition errors using the variable id
4744 WFLs. Generate initialization code if necessary. If the variable
4745 type is incomplete, register a patch on its decl.
4746 (source_start_java_method): Rewritten. Define a new block for the
4747 function's parameters. Build parameter decl out of function's
4748 arguments and register them for a patch if their types are

4751 source_start_java_method that was pushing the parameter decls and
4752 completing the method start code.

4754 poplevel (already taken care of). Reinstall function's arguments
4755 and get function's last line of code before calling
4756 expand_function_end.

4758 code. Complement the second operand of the current COMPOUND_EXPR

4764 enter_block and exit_block when defining it. For all methods:
4765 expand function's start calling the new expand_start_java_method
4766 and invoke java_complete_tree on the effective method's body, if
4768 (resolve_expression_name): Now use lookup_name_in_blocks to search
4769 local variable decls and print out an error when variables are
4771 (patch_method_invocation_stmt): Inserted comment before the

4774 with the current arg list as a second argument. Inserted missing
4775 IDENTIFIER_POINTER when reporting an error on methods not found.
4776 (refine_accessible_methods_list): Don't retain constructors.
4777 (patch_arguments): Function removed.
4778 (java_complete_tree): Inserted comment before the function's
4779 code. New case for BLOCKs. Moved the WFL case a bit
4780 further. Complete function's arguments.
4781 (build_expr_block, enter_block, exit_block, lookup_name_in_blocks,
4782 maybe_absorb_scoping_blocks): New functions.
