5754 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
5756 We used to have three different representations of the constant pool:
5757 the CPool structure, the tree_constant_pool, and the constructures
5758 used to build the Class object (which may need class and string
5759 constants) in compiled code. None were appropriate for compiling
5760 to .class files, so I did a major overhaul.
5762 First, the tree_constant_pool array was removed. Things were
5763 modified to the CPool structure in the JCF could be used.
5764 Second, a "capacity" field was added to the CPool, and functions
5765 written to search for a matching constant, adding one if not found.
5766 The code that generated the Class object was changed to use a CPool.
5767 The actual TREE_LISTs used to build the CONSTRUCTORs used for
5768 the static Class object are now only in build_constants_constructor.
5769 Finally, I wrote code which can generate a .class file (including its
5770 constant pool) from the RECORD_TYPE of a class. This is a big step
5771 on the way to compiling Java source into .class files.
5773 * jcf-write.c: New file. Writes out a RECORD_TYPE as a .class file.

5897 argument's completion didn't work. MODIFY_EXPR can have a WFL as a
5898 RHS. Fixed bug in the handling of bogus RHS of a fixed type. Now
5899 handle unary operator nodes.
5900 (build_assignment): Added comment.
5901 (print_int_node): New function.
5902 (patch_assignment): New second argument. New error handling. Use
5903 print_int_node. Handle references. Use can_cast_to_p to issue

5962 (operator_string): Handle more case. Compacted source.
5963 (patch_binop): Changed function comment. Checking for
5964 uninitialized first operand takes the compound assignment into
5965 account and uses DECL_P. Checking for uninitialized second operand
5966 delayed to routine's end. Use macros to issue type bound error
5967 messages and issue messages on both operands if their types are
5968 different. Force fixed type into node. Handle all binary

6011 completion of the previous one triggered errors.

6021 result of operand completion on COMPOUND_EXPR. Assign the
6022 encapsulated node of a WFL to the result of its completion, except
6023 when the node is an identifier. Now handle MODIFY_EXPR and several

6062 * parse.y (source_start_java_method): Use TREE_SET_CODE instead

6109 (variable_initializer:): Installed default rule on expression:.
6110 (method_declaration:): method_header: starts a new
6111 method. method_body: installs the function body, absorbs blocks
6112 emitted for temporary variable scopings, pops function's body block
6113 and merges function's last statement lineno in DECL_SOURCE_LINE.
6114 (method_body:): Installed default rules.

6116 scoping blocks and call exit_block when a closing brace is seen.

6120 (method_header): Try to use first_ccb_indent1 as the first line of
6121 the method, so BP debug info are emitted at the first opening
6122 brace of the function. If the function has no body, use the
6123 location of the function's name. Override currently defined method
6124 name with the matching WFL so we can point redefinition errors
6125 using the location where the function's name was declared.
6126 (check_abstract_method_header): Interprets DECL_NAME as an
6127 identifier or as a WFL, accordingly.
6128 (java_complete_class): New cases for JDEP_TYPE and JDEP_PARM.

6137 new variable(s) if code has been already generated at that nesting
6138 level. Pinpoint redefinition errors using the variable id
6139 WFLs. Generate initialization code if necessary. If the variable
6140 type is incomplete, register a patch on its decl.
6141 (source_start_java_method): Rewritten. Define a new block for the
6142 function's parameters. Build parameter decl out of function's
6143 arguments and register them for a patch if their types are

6146 source_start_java_method that was pushing the parameter decls and
6147 completing the method start code.

6149 poplevel (already taken care of). Reinstall function's arguments
6150 and get function's last line of code before calling

6153 code. Complement the second operand of the current COMPOUND_EXPR

6161 and invoke java_complete_tree on the effective method's body, if
6163 (resolve_expression_name): Now use lookup_name_in_blocks to search
6164 local variable decls and print out an error when variables are
6166 (patch_method_invocation_stmt): Inserted comment before the
6168 (lookup_method_invoke): Chain method's arguments using chainon
6169 with the current arg list as a second argument. Inserted missing
6170 IDENTIFIER_POINTER when reporting an error on methods not found.
6171 (refine_accessible_methods_list): Don't retain constructors.
6172 (patch_arguments): Function removed.
6173 (java_complete_tree): Inserted comment before the function's
6174 code. New case for BLOCKs. Moved the WFL case a bit
6175 further. Complete function's arguments.

7540 * decl.c: Define and build class_type, field_type, utf8const_type.
7541 * class.c (make_class_data, make_field_value,
7542 get_access_flags_from_decl, build_class_ref, build_utf8_ref,
7543 hashUtf8String, strLengthUtf8, mangled_classname:
7544 Functions to build reflective data structures.
7545 * parse.c (yyparse): Call make_class_data.
7547 * jcf-io.c (open_class, find_classfile): New functions.
7548 * jcf-dump.c: Support reading classfile from explicitly-named
7549 class file (without CLASSPATH searching).

7553 * jcf-reader.c: Add parameter list to HANDLE_CONSTANT_Utf8.
7554 * parse.c (JPOOL_UTF_LENGTH, JPOOL_UTF_DATA, HANDLE_CONSTANT_Utf8):
7555 Override jcf-reader macros so CONSTANT_Utf8 becomes tree node here.
7556 (get_constant): Now trivial for CONSTANT_Utf8.
7558 * jcf.h: Make NEW_CPOOL the default.
7559 * jcf.h, jcf-reader.c, parse.c: Remove support for !NEW_CPOOL.
