5773 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
5775 We used to have three different representations of the constant pool:
5776 the CPool structure, the tree_constant_pool, and the constructures
5777 used to build the Class object (which may need class and string
5778 constants) in compiled code. None were appropriate for compiling
5779 to .class files, so I did a major overhaul.
5781 First, the tree_constant_pool array was removed. Things were
5782 modified to the CPool structure in the JCF could be used.
5783 Second, a "capacity" field was added to the CPool, and functions
5784 written to search for a matching constant, adding one if not found.
5785 The code that generated the Class object was changed to use a CPool.
5786 The actual TREE_LISTs used to build the CONSTRUCTORs used for
5787 the static Class object are now only in build_constants_constructor.
5788 Finally, I wrote code which can generate a .class file (including its
5789 constant pool) from the RECORD_TYPE of a class. This is a big step
5790 on the way to compiling Java source into .class files.
5792 * jcf-write.c: New file. Writes out a RECORD_TYPE as a .class file.

5917 RHS. Fixed bug in the handling of bogus RHS of a fixed type. Now
5918 handle unary operator nodes.
5919 (build_assignment): Added comment.
5920 (print_int_node): New function.
5921 (patch_assignment): New second argument. New error handling. Use

5981 (operator_string): Handle more case. Compacted source.
5982 (patch_binop): Changed function comment. Checking for
5983 uninitialized first operand takes the compound assignment into
5984 account and uses DECL_P. Checking for uninitialized second operand
5985 delayed to routine's end. Use macros to issue type bound error
5986 messages and issue messages on both operands if their types are
5987 different. Force fixed type into node. Handle all binary

6030 completion of the previous one triggered errors.

6128 (variable_initializer:): Installed default rule on expression:.
6129 (method_declaration:): method_header: starts a new
6130 method. method_body: installs the function body, absorbs blocks

6135 scoping blocks and call exit_block when a closing brace is seen.

6139 (method_header): Try to use first_ccb_indent1 as the first line of
6140 the method, so BP debug info are emitted at the first opening
6141 brace of the function. If the function has no body, use the
6142 location of the function's name. Override currently defined method
6143 name with the matching WFL so we can point redefinition errors
6144 using the location where the function's name was declared.
6145 (check_abstract_method_header): Interprets DECL_NAME as an
6146 identifier or as a WFL, accordingly.
6147 (java_complete_class): New cases for JDEP_TYPE and JDEP_PARM.

6156 new variable(s) if code has been already generated at that nesting
6157 level. Pinpoint redefinition errors using the variable id
6158 WFLs. Generate initialization code if necessary. If the variable
6159 type is incomplete, register a patch on its decl.
6160 (source_start_java_method): Rewritten. Define a new block for the
6161 function's parameters. Build parameter decl out of function's
6162 arguments and register them for a patch if their types are

6165 source_start_java_method that was pushing the parameter decls and
6166 completing the method start code.

6168 poplevel (already taken care of). Reinstall function's arguments
6169 and get function's last line of code before calling

6172 code. Complement the second operand of the current COMPOUND_EXPR

6180 and invoke java_complete_tree on the effective method's body, if

6183 local variable decls and print out an error when variables are
6185 (patch_method_invocation_stmt): Inserted comment before the
6187 (lookup_method_invoke): Chain method's arguments using chainon
6188 with the current arg list as a second argument. Inserted missing
6189 IDENTIFIER_POINTER when reporting an error on methods not found.
6190 (refine_accessible_methods_list): Don't retain constructors.
6191 (patch_arguments): Function removed.
6192 (java_complete_tree): Inserted comment before the function's
6193 code. New case for BLOCKs. Moved the WFL case a bit
6194 further. Complete function's arguments.
