Subject: basic-block.h (find_sub_basic_blocks): Use sbitmap parameter.

	* basic-block.h (find_sub_basic_blocks): Use sbitmap parameter.
	* cfgbuild.c (find_bb_boundaries, compute_outgoing_frequencies):
	Break out from ...
	(find_sub_basic_blocks): ... here;
	(find_many_sub_basic_blocks): New.
	* recog.c (split_all_insns): Update find_sub_basic_blocks call.

	* i386.h (ASM_PREFERRED_EH_DATA_FORMAT): Define sdata4.

	* i386.c (ix86_va_arg): Kill indirect_p handling; fix aliasing issues.:

	* i386.c (split_di, split_ti): Revamp to use simplify_subreg.

	* timevar.def (TV_LIFE, TV_LIFE_UPDATE, TV_MODE_SWITCH): new.
	* flow.c (update_life_info): Measure time.
	* c-decl.c: Include timevar.h
	(c_expand_body): Measure time.
	* toplev.c (rest_of_compilation): Measure time of mode switching
	separately.
	* Makefile.in (c-decl.o, cfgcleanup.o): Add dependancy.

	* toplev.c (flag_asynchronous_unwind_tables): New global variable.
	(lang_independent_options): Add asynchronous-unwind-tables
	(toplev_main): flag_asynchronous_unwind_tables implies
	flag_unwind_tables.
	* flags.h (flag_asynchronous_unwind_tables): Declare.
	* dwarf2out.c (dwarf2out_stack_adjust): Take into account
	flag_asynchronous_unwind_tables.
	(output_call_frame_info): Likewise.
	* invoke.texi (-fasynchronous-unwind-tables): Document.
	* i386.c (optimization_options): Enable
	flag_asynchronous_unwind_tables.

	* i386.c (ix86_expand_setcc):  Always expect target to be QImode.
	* i386.md (s* expanders): Destination is QImode.

	* toplev.c (rest_of_compilation): Do not call clear_log_links.
	* rtl.h (clear_log_links): Kill.
	* flow.c (clear_log_links): Make static; accept blocks parameter;
	do no clear life info.
