5741 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
5743 We used to have three different representations of the constant pool:
5744 the CPool structure, the tree_constant_pool, and the constructures
5745 used to build the Class object (which may need class and string
5746 constants) in compiled code. None were appropriate for compiling
5747 to .class files, so I did a major overhaul.
5749 First, the tree_constant_pool array was removed. Things were
5750 modified to the CPool structure in the JCF could be used.
5751 Second, a "capacity" field was added to the CPool, and functions
5752 written to search for a matching constant, adding one if not found.
5753 The code that generated the Class object was changed to use a CPool.
5754 The actual TREE_LISTs used to build the CONSTRUCTORs used for
5755 the static Class object are now only in build_constants_constructor.
5756 Finally, I wrote code which can generate a .class file (including its
5757 constant pool) from the RECORD_TYPE of a class. This is a big step
5758 on the way to compiling Java source into .class files.

5805 availability. Both are narrowed down to an 8 bits bitfield.
5806 (CALL_EXPR_PRIMARY): Fixed comment.
5808 Wed Jun 10 10:54:39 1998 Tom Tromey <tromey@cygnus.com>

5884 argument's completion didn't work. MODIFY_EXPR can have a WFL as a
5885 RHS. Fixed bug in the handling of bogus RHS of a fixed type. Now
5886 handle unary operator nodes.
5887 (build_assignment): Added comment.
5888 (print_int_node): New function.
5889 (patch_assignment): New second argument. New error handling. Use
5890 print_int_node. Handle references. Use can_cast_to_p to issue

5949 (operator_string): Handle more case. Compacted source.
5950 (patch_binop): Changed function comment. Checking for
5951 uninitialized first operand takes the compound assignment into
5952 account and uses DECL_P. Checking for uninitialized second operand
5953 delayed to routine's end. Use macros to issue type bound error
5954 messages and issue messages on both operands if their types are
5955 different. Force fixed type into node. Handle all binary
5958 Wed May 27 10:30:31 1998 Alexandre Petit-Bianco <apbianco@cygnus.com>

5998 completion of the previous one triggered errors.

6008 result of operand completion on COMPOUND_EXPR. Assign the
6009 encapsulated node of a WFL to the result of its completion, except
6010 when the node is an identifier. Now handle MODIFY_EXPR and several

6049 * parse.y (source_start_java_method): Use TREE_SET_CODE instead

6096 (variable_initializer:): Installed default rule on expression:.
6097 (method_declaration:): method_header: starts a new
6098 method. method_body: installs the function body, absorbs blocks
6099 emitted for temporary variable scopings, pops function's body block
6100 and merges function's last statement lineno in DECL_SOURCE_LINE.
6101 (method_body:): Installed default rules.

6103 scoping blocks and call exit_block when a closing brace is seen.

6107 (method_header): Try to use first_ccb_indent1 as the first line of
6108 the method, so BP debug info are emitted at the first opening
6109 brace of the function. If the function has no body, use the
6110 location of the function's name. Override currently defined method
6111 name with the matching WFL so we can point redefinition errors
6112 using the location where the function's name was declared.
6113 (check_abstract_method_header): Interprets DECL_NAME as an
6114 identifier or as a WFL, accordingly.
6115 (java_complete_class): New cases for JDEP_TYPE and JDEP_PARM.

6124 new variable(s) if code has been already generated at that nesting
6125 level. Pinpoint redefinition errors using the variable id
6126 WFLs. Generate initialization code if necessary. If the variable
6127 type is incomplete, register a patch on its decl.
6128 (source_start_java_method): Rewritten. Define a new block for the
6129 function's parameters. Build parameter decl out of function's
6130 arguments and register them for a patch if their types are

6133 source_start_java_method that was pushing the parameter decls and
6134 completing the method start code.

6136 poplevel (already taken care of). Reinstall function's arguments
6137 and get function's last line of code before calling

6140 code. Complement the second operand of the current COMPOUND_EXPR

6148 and invoke java_complete_tree on the effective method's body, if
6150 (resolve_expression_name): Now use lookup_name_in_blocks to search
6151 local variable decls and print out an error when variables are
6153 (patch_method_invocation_stmt): Inserted comment before the
6155 (lookup_method_invoke): Chain method's arguments using chainon
6156 with the current arg list as a second argument. Inserted missing
6157 IDENTIFIER_POINTER when reporting an error on methods not found.
6158 (refine_accessible_methods_list): Don't retain constructors.
6159 (patch_arguments): Function removed.
6160 (java_complete_tree): Inserted comment before the function's
6161 code. New case for BLOCKs. Moved the WFL case a bit
6162 further. Complete function's arguments.

7540 * jcf-reader.c: Add parameter list to HANDLE_CONSTANT_Utf8.
7541 * parse.c (JPOOL_UTF_LENGTH, JPOOL_UTF_DATA, HANDLE_CONSTANT_Utf8):
7542 Override jcf-reader macros so CONSTANT_Utf8 becomes tree node here.
7543 (get_constant): Now trivial for CONSTANT_Utf8.
7545 * jcf.h: Make NEW_CPOOL the default.
7546 * jcf.h, jcf-reader.c, parse.c: Remove support for !NEW_CPOOL.
