* combine.c (force_to_mode) <NE_EXPR>: Only convert the expression
(AND (NE FOO 0) CONST) into (AND FOO CONST) if FOO has the same
machine mode as the result.
From-SVN: r88369
* jcf-parse.c (parse_class_file): Use linemap_line_start.
(parse_source_file_1): Pass filename as extra parameter, so we can call
linemap_add and set input_location here, rather than in both callers.
(read_class): Pass copied filename to parse_source_file_1.
Don't initialize wfl_operator - only needed for source compilation.
(read_class, jcf_parse): Call linemap_add with LC_LEAVE.
* lex.h: Remove a bunch of debugging macros.
* lex.h (struct_java_line, struct java_error): Remove types.
(JAVA_COLUMN_DELTA): Remove - use java_lexer.next_colums instead.
(struct java_lc_s): Remove prev_col field.
(struct java_lexer): New fields next_unicode, next_columns, and
avail_unicode. New position field, and maybe token_start field.
Don't need hit_eof field - use next_unicode == -1 instead.
(JAVA_INTEGERAL_RANGE_ERROR): Rename to JAVA_RANGE_ERROR.
(JAVA_RANGE_ERROR, JAVA_FLOAT_ANGE_ERROR): Update accordingly.
* parse.h: Various changes for USE_MAPPED_LOCATION.

(BUILD_EXPR_WFL, EXPR_WFL_ADD_COL): Remove no-longer-used macros.
(struct parser_ctxt): New file_start_location field.
Remove p_line, c_line fields since we no longer save lines.
Remove elc, lineno, and current_jcf fields - no longer used.
* parse.y: Updates for USE_MAPPED_LOCATION and new lexer.
Don't use EXPR_WFL_ADD_COL since that isn't trivial with
source_location and is probably not needed anymore anyway.
Use new expr_add_Location function.
(SET_EXPR_LOCATION_FROM_TOKEN): New convenience macro.
(java_pop_parser_context): Minor cleanup.
(java_parser_context_save_global, java_parser_context_restore_global,

(issue_warning_error_from_context): If USE_MAPPED_LOCATION take
a source_location instead of a wfl context node.
(check_class_interface_creation): input_filename is not addressable.
(create_artificial_method): Calling java_parser_context_save_global
and java_parser_context_restore_global is overkill. Instead,
temporarily set input_location from class decl.
(java_layout_seen_class_methods): Set input_location from method decl.
(fix_constructors): Make more robust if no EXPR_WITH_FILE_LOCATION.

(java_sneak_uncode): Replaced by java_peek_unicode.
(java_unget_unicode): No longer used.
(java_allocate_new_line. java_store_unicode): Removed, since we
no longer remember "lines".

(java_read_char): Move unget_value checking to java_read_unicode.
(java_get_unicode, java_peek_unicode, java_next_unicode): New more
efficient functions that are used directly when lexing.
(java_read_unicode_collapsing_terminators): No longer needed.
(java_parse_end_comment, java_parse_escape_sequence, do_java_lex):
Re-organize to use java_peek_unicode to avoid java_unget_unicode.
(java_parse_escape_sequence): Rewrite to be simpler / more efficient.
(do_java_lex): Lots of movings around to avoid java_unget_unicode,
combine switch branches, and test for common token kinds earlier.
(java_lex_error): Rewrite.
* jv-scan.c (expand_location): New function, copied from tree.c.
(main): Set ctxp->filename instead of setting input_filename directly.
From-SVN: r88367
* java-tree.h (JAVA_FILE_P, ZIP_FILE_P): Remove unused macros.
* jcf-parse.c (java_parse_file): Don't set input_filename.
Use IS_A_COMMAND_LINE_FILENAME_P to check for duplicate filenames.
Create a list of TRANSLATION_UNIT_DECL.
(current_file_list): Is now a TRANSLATION_UNIT_DECL chain. The
reason is so we can set a DECL_SOURCE_LOCATION for each file.
(java_parse_file): Don't set unused ZIP_FILE_P, JAVA_FILE_P..
Create line-map LC_ENTER/LC_LEAVE entries for archive itself.
(file_start_location): New static.

(give_name_to_class): Set class's "line 0" input_location here.
(parse_class_file): Set input_location as a unit.
* jcf-parse.c (load_class): Sanity test if missing inner class file.
From-SVN: r88366
* class.c (push_class): If USE_MAPPED_LOCATION don't set
input_location here. Instead do it in give_name_to_class.
(build_class_ref): Set DECL_ARTIFICIAL, for the sake of dwarf2out.
* expr.c (expand_byte_code): Call linemap_line_start.
* expr.c (build_expr_wfl): If USE_MAPPED_LOCATION, change final
parameters to a source_location. Don't need EXPR_WFL_FILENAME_NODE.
(expr_add_location): New function, if USE_MAPPED_LOCATION.
* class.c (maybe_layout_super_class): Adjust build_expr_wfl call
to USE_MAPPED_LOCATION case.
