Fri Jun 12 11:31:24 1998  Per Bothner  <bothner@cygnus.com>

        We used to have three different representations of the constant pool:
        the CPool structure, the tree_constant_pool, and the constructures
        used to build the Class object (which may need class and string
        constants) in compiled code.  None were appropriate for compiling
        to .class files, so I did a major overhaul.

        First, the tree_constant_pool array was removed.  Things were
        modified to the CPool structure in the JCF could be used.
        Second, a "capacity" field was added to the CPool, and functions
        written to search for a matching constant, adding one if not found.
        The code that generated the Class object was changed to use a CPool.
        The actual TREE_LISTs used to build the CONSTRUCTORs used for
        the static Class object are now only in build_constants_constructor.
        Finally, I wrote code which can generate a .class file (including its
        constant pool) from the RECORD_TYPE of a class.  This is a big step
        on the way to compiling Java source into .class files.

        identifiers. JDEPs are now part of the jdep_code enum.

        code.
        (operator_string): Handle more case. Compacted source.
        (patch_binop): Changed function comment. Checking for
        uninitialized first operand takes the compound assignment into

        delayed to routine's end. Use macros to issue type bound error
        messages and issue messages on both operands if their types are
        different. Force fixed type into node. Handle all binary

        tagged <node>
        (SOURCE_FRONTEND_DEBUG): Used as macro accepting varargs.
        (compilation_unit:): Cosmetic on sub rule.
        (type_declaration:): Cosmetic on sub rules. Added an error rule.
        (variable_initializer:): Installed default rule on expression:.
        (method_declaration:): method_header: starts a new
        method. method_body: installs the function body, absorbs blocks
        emitted for temporary variable scopings, pops function's body block
        and merges function's last statement lineno in DECL_SOURCE_LINE.
        (method_body:): Installed default rules.
        (block:): Call enter_block when an opening brace is seen.  Absorb
        scoping blocks and call exit_block when a closing brace is seen.

        brace of the function. If the function has no body, use the
        location of the function's name. Override currently defined method
        name with the matching WFL so we can point redefinition errors
        using the location where the function's name was declared.
        (check_abstract_method_header): Interprets DECL_NAME as an
        identifier or as a WFL, accordingly.
        (java_complete_class): New cases for JDEP_TYPE and JDEP_PARM.

        function's source code).
        (read_import_dir): Test the value returned by find_class and issue
        a fatal accordingly.
        (declare_local_variables): Push a new block for the scope of the
        new variable(s) if code has been already generated at that nesting
        level. Pinpoint redefinition errors using the variable id
        WFLs. Generate initialization code if necessary. If the variable
        type is incomplete, register a patch on its decl.
        (source_start_java_method): Rewritten. Define a new block for the
        function's parameters. Build parameter decl out of function's
        arguments and register them for a patch if their types are
        incomplete.
        (expand_start_java_method): Includes the part of
        source_start_java_method that was pushing the parameter decls and
        completing the method start code.
        (source_end_java_method): Removed call the expand_end_bindings and
        poplevel (already taken care of). Reinstall function's arguments
        and get function's last line of code before calling
        expand_function_end.
        (java_method_add_stmt): New comment before the function's
        code. Complement the second operand of the current COMPOUND_EXPR
        if necessary.
        (java_complete_expand_methods): Don't generate debug info on line
        zero when expanding a generated constructor.
        (java_complete_expand_method): Set start and end line numbers for
        a artificially generated constructor to one and manually call
        enter_block and exit_block when defining it. For all methods:
        expand function's start calling the new expand_start_java_method
        and invoke java_complete_tree on the effective method's body, if
        any.
        (resolve_expression_name): Now use lookup_name_in_blocks to search
        local variable decls and print out an error when variables are
        undefined.
        (patch_method_invocation_stmt): Inserted comment before the
        function's code.
        (lookup_method_invoke): Chain method's arguments using chainon
        with the current arg list as a second argument. Inserted missing
        IDENTIFIER_POINTER when reporting an error on methods not found.
        (refine_accessible_methods_list): Don't retain constructors.
        (patch_arguments): Function removed.
        (java_complete_tree): Inserted comment before the function's
        code. New case for BLOCKs. Moved the WFL case a bit
        further. Complete function's arguments.
        (build_expr_block, enter_block, exit_block, lookup_name_in_blocks,
        maybe_absorb_scoping_blocks): New functions.
