5674 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
5676 We used to have three different representations of the constant pool:
5677 the CPool structure, the tree_constant_pool, and the constructures
5678 used to build the Class object (which may need class and string
5679 constants) in compiled code. None were appropriate for compiling
5680 to .class files, so I did a major overhaul.
5682 First, the tree_constant_pool array was removed. Things were
5683 modified to the CPool structure in the JCF could be used.
5684 Second, a "capacity" field was added to the CPool, and functions
5685 written to search for a matching constant, adding one if not found.
5686 The code that generated the Class object was changed to use a CPool.
5687 The actual TREE_LISTs used to build the CONSTRUCTORs used for
5688 the static Class object are now only in build_constants_constructor.
5689 Finally, I wrote code which can generate a .class file (including its
5690 constant pool) from the RECORD_TYPE of a class. This is a big step
5691 on the way to compiling Java source into .class files.

5804 with a promoted type.
5805 (declare_local_variables): Resolved non builtin types are promoted
5806 before being used to build a variable decl. Removed type patch
5807 posted on variable initialization statement.
5808 (source_start_java_method): Use build_decl_no_layout to build the
5809 decl of a parameter of incomplete type.

5815 has a type. Propagate error_mark_node to node's type too. Promote
5816 method's call argument type and return error_mark_node if
5817 argument's completion didn't work. MODIFY_EXPR can have a WFL as a
5818 RHS. Fixed bug in the handling of bogus RHS of a fixed type. Now
5819 handle unary operator nodes.
5820 (build_assignment): Added comment.
5821 (print_int_node): New function.
5822 (patch_assignment): New second argument. New error handling. Use
5823 print_int_node. Handle references. Use can_cast_to_p to issue
5824 different error message according to the context and check upon

5882 (operator_string): Handle more case. Compacted source.
5883 (patch_binop): Changed function comment. Checking for
5884 uninitialized first operand takes the compound assignment into
5885 account and uses DECL_P. Checking for uninitialized second operand
5886 delayed to routine's end. Use macros to issue type bound error
5887 messages and issue messages on both operands if their types are
5888 different. Force fixed type into node. Handle all binary

5931 completion of the previous one triggered errors.

5941 result of operand completion on COMPOUND_EXPR. Assign the
5942 encapsulated node of a WFL to the result of its completion, except
5943 when the node is an identifier. Now handle MODIFY_EXPR and several

6030 (method_declaration:): method_header: starts a new
6031 method. method_body: installs the function body, absorbs blocks
6032 emitted for temporary variable scopings, pops function's body block
6033 and merges function's last statement lineno in DECL_SOURCE_LINE.
6034 (method_body:): Installed default rules.

6036 scoping blocks and call exit_block when a closing brace is seen.

6039 (patch_stage): Added comment around definition.
6040 (method_header): Try to use first_ccb_indent1 as the first line of
6041 the method, so BP debug info are emitted at the first opening
6042 brace of the function. If the function has no body, use the
6043 location of the function's name. Override currently defined method
6044 name with the matching WFL so we can point redefinition errors
6045 using the location where the function's name was declared.
6046 (check_abstract_method_header): Interprets DECL_NAME as an
6047 identifier or as a WFL, accordingly.
6048 (java_complete_class): New cases for JDEP_TYPE and JDEP_PARM.

6058 level. Pinpoint redefinition errors using the variable id
6059 WFLs. Generate initialization code if necessary. If the variable
6060 type is incomplete, register a patch on its decl.
6061 (source_start_java_method): Rewritten. Define a new block for the
6062 function's parameters. Build parameter decl out of function's
6063 arguments and register them for a patch if their types are

6066 source_start_java_method that was pushing the parameter decls and
6067 completing the method start code.

6069 poplevel (already taken care of). Reinstall function's arguments

6084 local variable decls and print out an error when variables are
6086 (patch_method_invocation_stmt): Inserted comment before the

6089 with the current arg list as a second argument. Inserted missing
6090 IDENTIFIER_POINTER when reporting an error on methods not found.
6091 (refine_accessible_methods_list): Don't retain constructors.
6092 (patch_arguments): Function removed.
6093 (java_complete_tree): Inserted comment before the function's
6094 code. New case for BLOCKs. Moved the WFL case a bit
6095 further. Complete function's arguments.
