* toplev.c (rest_of_compilation): Set bct_p on second call to
loop_optimize.
* loop.c (loop_optimize, scan_loop, strength_reduce): New argument
bct_p.
(strength_reduce): Only call analyze_loop_iterations and
insert_bct if bct_p set.
(check_dbra_loop): Fix typo.
(insert_bct): Use word_mode instead of SImode.
(instrument_loop_bct): Likewise. Do not delete iteration count
condition code generation insn. Initialize iteration count before
loop start.
* rtl.h (loop_optimize): Update prototype.
* ginclude/va-ppc.h (va_arg): longlong types in overflow area are
not doubleword aligned.
* rs6000.c (optimization_options): New function.
(secondary_reload_class): Only call true_regnum for PSEUDO_REGs.
* rs6000.h (OPTIMIZATION_OPTIONS): Define.
(REG_ALLOC_ORDER): Allocate highest numbered condition regsiters
first; cr1 can be used for FP record condition insns.
From-SVN: r22471
* g++.old-deja/g++.other/nested2.C: different virtual base classes
that happen to have the same base name, but in different scopes,
are incorrectly rejected

* objc/config-lang.in: Do not output the name of the selected
thread file when building the front-end. The Makefile for the
runtime library will do this.
* objc/Make-lang.in: Do not build the runtime library or install
the Objective C header files. The Makefile for the runtime
library will do this.
* objc/Makefile.in (all.indirect): Only build the front-end.
(compiler): Rename to `frontend'.
(obj-runtime): Remove target.
(copy-headers): Likewise.
(clean): No need to remove `libobjc.a' any longer.
From-SVN: r22459
* gen-protos.c (parse_fn_proto): Cast argument of ISALNUM to
`unsigned char'.
(main): Mark parameter `argc' with ATTRIBUTE_UNUSED.
When generating output, initialize missing struct member to zero.
From-SVN: r22449
* global.c (reg_allocno): Now static.
* reload1.c (reg_allocno): Delete declaration.
(order_regs_for_reload): Take no arguments. Don't treat regs
allocated by global differently than those allocated by local-alloc.
From-SVN: r22446
* gcse.c: New definition NEVER_SET for reg_first_set, reg_last_set,
mem_first_set, mem_last_set; because 0 can be a CUID.
(oprs_unchanged_p): Use new definition.
(record_last_reg_set_info): Likewise.
(record_last_mem_set_info): Likewise.
(compute_hash_table): Likewise.
From-SVN: r22441
* combine.c (make_extraction): If no mode is specified for
an operand of insv, extv, or extzv, default it to word_mode.
(simplify_comparison): Similarly.
* expmed.c (store_bit_field): Similarly.
(extract_bit_field): Similarly.
* function.c (fixup_var_regs_1): Similarly.
* recog.c (validate_replace_rtx_1): Similarly.
* mips.md (extv, extzv, insv expanders): Default modes for most
operands. Handle TARGET_64BIT.
(movdi_uld, movdi_usd): New patterns.
From-SVN: r22439
�
* pa.c (emit_move_sequence): Do not replace a pseudo with its
equivalent memory location unless we have been provided a scratch
register. Similarly do not call find_replacement unless a
scratch register has been provided.

* except.h (struct eh_entry): Add false_label field.
(end_catch_handler): Add prototype.
* except.c (push_eh_entry): Set false_label field to NULL_RTX.

runtime typematch code before continuing with the handler.
(end_catch_handler): New function, generates label after handler
if needed by older style exceptions.
(expand_start_all_catch): No need to check for new style exceptions.
(output_exception_table_entry): Only output the first handler label
for old style exceptions.
* libgcc2.c (__eh_rtime_match): New routine to lump runtime matching
mechanism into one function, if a runtime matcher is provided.

* cp/except.c (expand_start_catch_block): No need to check for new
exception model.
(process_start_catch_block_old): Deleted.
(process_start_catch_block): Add call to start_decl_1().
(expand_end_catch_block): Add call to end_catch_handler().
* cp/exception.cc (__cplus_type_matcher): Only check the exception
language if there is an exception table.
