5748 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
5750 We used to have three different representations of the constant pool:
5751 the CPool structure, the tree_constant_pool, and the constructures
5752 used to build the Class object (which may need class and string
5753 constants) in compiled code. None were appropriate for compiling
5754 to .class files, so I did a major overhaul.
5756 First, the tree_constant_pool array was removed. Things were
5757 modified to the CPool structure in the JCF could be used.
5758 Second, a "capacity" field was added to the CPool, and functions
5759 written to search for a matching constant, adding one if not found.
5760 The code that generated the Class object was changed to use a CPool.
5761 The actual TREE_LISTs used to build the CONSTRUCTORs used for
5762 the static Class object are now only in build_constants_constructor.
5763 Finally, I wrote code which can generate a .class file (including its
5764 constant pool) from the RECORD_TYPE of a class. This is a big step
5765 on the way to compiling Java source into .class files.

5891 argument's completion didn't work. MODIFY_EXPR can have a WFL as a
5892 RHS. Fixed bug in the handling of bogus RHS of a fixed type. Now
5893 handle unary operator nodes.
5894 (build_assignment): Added comment.
5895 (print_int_node): New function.
5896 (patch_assignment): New second argument. New error handling. Use
5897 print_int_node. Handle references. Use can_cast_to_p to issue

5956 (operator_string): Handle more case. Compacted source.
5957 (patch_binop): Changed function comment. Checking for
5958 uninitialized first operand takes the compound assignment into
5959 account and uses DECL_P. Checking for uninitialized second operand
5960 delayed to routine's end. Use macros to issue type bound error
5961 messages and issue messages on both operands if their types are
5962 different. Force fixed type into node. Handle all binary

6005 completion of the previous one triggered errors.

6103 (variable_initializer:): Installed default rule on expression:.
6104 (method_declaration:): method_header: starts a new
6105 method. method_body: installs the function body, absorbs blocks

6110 scoping blocks and call exit_block when a closing brace is seen.

6114 (method_header): Try to use first_ccb_indent1 as the first line of
6115 the method, so BP debug info are emitted at the first opening
6116 brace of the function. If the function has no body, use the
6117 location of the function's name. Override currently defined method
6118 name with the matching WFL so we can point redefinition errors
6119 using the location where the function's name was declared.

6132 level. Pinpoint redefinition errors using the variable id
6133 WFLs. Generate initialization code if necessary. If the variable
6134 type is incomplete, register a patch on its decl.
6135 (source_start_java_method): Rewritten. Define a new block for the
6136 function's parameters. Build parameter decl out of function's
6137 arguments and register them for a patch if their types are

6141 completing the method start code.

6143 poplevel (already taken care of). Reinstall function's arguments
6144 and get function's last line of code before calling

6147 code. Complement the second operand of the current COMPOUND_EXPR

6155 and invoke java_complete_tree on the effective method's body, if

6158 local variable decls and print out an error when variables are
6160 (patch_method_invocation_stmt): Inserted comment before the
6162 (lookup_method_invoke): Chain method's arguments using chainon
6163 with the current arg list as a second argument. Inserted missing
6164 IDENTIFIER_POINTER when reporting an error on methods not found.
6165 (refine_accessible_methods_list): Don't retain constructors.
6166 (patch_arguments): Function removed.
6167 (java_complete_tree): Inserted comment before the function's
6168 code. New case for BLOCKs. Moved the WFL case a bit
6169 further. Complete function's arguments.

7537 hashUtf8String, strLengthUtf8, mangled_classname:
7538 Functions to build reflective data structures.
7539 * parse.c (yyparse): Call make_class_data.
7541 * jcf-io.c (open_class, find_classfile): New functions.
7542 * jcf-dump.c: Support reading classfile from explicitly-named
7543 class file (without CLASSPATH searching).

7547 * jcf-reader.c: Add parameter list to HANDLE_CONSTANT_Utf8.
7548 * parse.c (JPOOL_UTF_LENGTH, JPOOL_UTF_DATA, HANDLE_CONSTANT_Utf8):
7549 Override jcf-reader macros so CONSTANT_Utf8 becomes tree node here.
7550 (get_constant): Now trivial for CONSTANT_Utf8.
7552 * jcf.h: Make NEW_CPOOL the default.
7553 * jcf.h, jcf-reader.c, parse.c: Remove support for !NEW_CPOOL.
