	gcc            : ChangeLog basic-block.h config.in cse.c 
	                 except.c flow.c integrate.c reg-stack.c rtl.h 
	                 sibcall.c timevar.def toplev.c 

Log message:
	* basic-block.h (CLEANUP_PRE_SIBCALL): New constant.
	* except.c (finish_eh_generation): Update call of cleanup_cfg;
	do rebuild_jump_labels instead of jump_optimize
	* sibcall.c (optimize_sibling_and_tail_recursive_call): Likewise.
	* toplev.c (rest_of_compulation): Likewise for -Wreturn_type.
	* flow.c (try_optimize_cfg): Remove unneeded code_labels.
	
	* flow.c: Include timevar.h
	(find_basic_block): Push/pop timevar;
	(cleanup_cfg): Likewise.
	* timevar.def (TV_CFG, TV_CLEANUP_CFG): New.
	* Makefile: Add dependencies on timevar.h
	
	* integrate.c (save_for_inline): Kill all BASIC_BLOCK notes.
	(copy_insn_list): Avoid killing of BASIC_BLOCK notes.
	
	* rtl.h (delete_trivially_dead_insns): Add new parameter.
	* toplev.c (rest_of_compilation): Update calls.
	* cse.c (set_live_p, insn_live_p, dead_libcall_p): Break out from ...
	(delete_trivially_dead_insns): ... here; accept new argument
	preserve_basic_blocks; preserve basic blocks if set.
	
	* reg-stack.c (stack_regs_mentioned): Return 0 if
	stack_regs_mentioned_data is not initialized.
	(reg_to_stack): Make stack_regs_mentioned survive after the
	reg-stack is completted; do not call cleanup_cfg.
	* toplev.c (rest_of_compilation): Do cleanup_cfg before bb-reorder;
	make cleanup_cfg after bb-reorder to output to debug file.
