5362 Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
5364 We used to have three different representations of the constant pool:
5365 the CPool structure, the tree_constant_pool, and the constructures
5366 used to build the Class object (which may need class and string
5367 constants) in compiled code. None were appropriate for compiling
5368 to .class files, so I did a major overhaul.
5370 First, the tree_constant_pool array was removed. Things were
5371 modified to the CPool structure in the JCF could be used.
5372 Second, a "capacity" field was added to the CPool, and functions
5373 written to search for a matching constant, adding one if not found.
5374 The code that generated the Class object was changed to use a CPool.
5375 The actual TREE_LISTs used to build the CONSTRUCTORs used for
5376 the static Class object are now only in build_constants_constructor.
5377 Finally, I wrote code which can generate a .class file (including its
5378 constant pool) from the RECORD_TYPE of a class. This is a big step
5379 on the way to compiling Java source into .class files.
5381 * jcf-write.c: New file. Writes out a RECORD_TYPE as a .class file.
5382 * Makefile.in (JAVA_OBJS): Added jcf-write.o.

5396 current_constant_pool_length), java-tree.h: Replaced by outgoing_cpool.
5397 * constants.c (build_constants_constructor): Use new outgoing_cpool.

5424 identifiers. JDEPs are now part of the jdep_code enum.
5425 (typedef struct jdep): Now use enum jdep_code or int, depending on
5426 availability. Both are narrowed down to an 8 bits bitfield.
5427 (CALL_EXPR_PRIMARY): Fixed comment.
5429 Wed Jun 10 10:54:39 1998 Tom Tromey <tromey@cygnus.com>

5502 (java_complete_tree): Process CONVERT_EXPR, even though it always
5503 has a type. Propagate error_mark_node to node's type too. Promote
5504 method's call argument type and return error_mark_node if
5505 argument's completion didn't work. MODIFY_EXPR can have a WFL as a
5506 RHS. Fixed bug in the handling of bogus RHS of a fixed type. Now
5507 handle unary operator nodes.
5508 (build_assignment): Added comment.
5509 (print_int_node): New function.
5510 (patch_assignment): New second argument. New error handling. Use
5511 print_int_node. Handle references. Use can_cast_to_p to issue
5512 different error message according to the context and check upon
5513 the initialization of the RHS.
5514 (can_cast_to_p, valid_ref_assignconv_cast_p): New functions.
5515 (operator_string): Handle more operators.
5516 (patch_binop): No longer use a function static

5568 (build_binop): Fix crash when using URSHIFT_EXPR, a Java only tree
5570 (operator_string): Handle more case. Compacted source.
5571 (patch_binop): Changed function comment. Checking for
5572 uninitialized first operand takes the compound assignment into
5573 account and uses DECL_P. Checking for uninitialized second operand
5574 delayed to routine's end. Use macros to issue type bound error
5575 messages and issue messages on both operands if their types are
5576 different. Force fixed type into node. Handle all binary
5579 Wed May 27 10:30:31 1998 Alexandre Petit-Bianco <apbianco@cygnus.com>
5581 * java-tree.h (COMPOUND_ASSIGN_P, INITIALIZED_P): New macros.

5619 completion of the previous one triggered errors.

5626 (patch_invoke): Removed unused local. Return the correct node.
5627 (java_complete_tree): Now returns a value. The BLOCK section binds
5628 local identifiers and the type of a BLOCK is now void. Assign the
5629 result of operand completion on COMPOUND_EXPR. Assign the
5630 encapsulated node of a WFL to the result of its completion, except
5631 when the node is an identifier. Now handle MODIFY_EXPR and several

5653 * jcf-parse.c (parse_class-file): Set lino to smallest line number,
5654 while initializing linenumber_count and linenumber_table.
5655 Do it before init_function_start (which calls emit_line_note).

5670 * parse.y (source_start_java_method): Use TREE_SET_CODE instead
5671 of assigning to TREE_CODE. The latter method exploits a feature

5715 (compilation_unit:): Cosmetic on sub rule.
5716 (type_declaration:): Cosmetic on sub rules. Added an error rule.
5717 (variable_initializer:): Installed default rule on expression:.
5718 (method_declaration:): method_header: starts a new
5719 method. method_body: installs the function body, absorbs blocks
5720 emitted for temporary variable scopings, pops function's body block
5721 and merges function's last statement lineno in DECL_SOURCE_LINE.
5722 (method_body:): Installed default rules.
5723 (block:): Call enter_block when an opening brace is seen. Absorb
5724 scoping blocks and call exit_block when a closing brace is seen.
5725 (block_statement:): Cosmetic changes.
5726 (method_invocation:): Create WFL around CALL_EXPR node.
5727 (patch_stage): Added comment around definition.
5728 (method_header): Try to use first_ccb_indent1 as the first line of
5729 the method, so BP debug info are emitted at the first opening
5730 brace of the function. If the function has no body, use the
5731 location of the function's name. Override currently defined method
5732 name with the matching WFL so we can point redefinition errors
5733 using the location where the function's name was declared.
5734 (check_abstract_method_header): Interprets DECL_NAME as an
5735 identifier or as a WFL, accordingly.
5736 (java_complete_class): New cases for JDEP_TYPE and JDEP_PARM.
5737 (check_method_redefinition): Use DECL_NAME as a WFL. Extract
