New Revision: 123223

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=123223
Log:
	* ifcvt.c (noce_try_store_flag_constants): Don't check
	no_new_pseudos here.
	(noce_try_store_flag_constants): Don't check no_new_pseudos.
	(noce_try_addcc, noce_try_store_flag_mask, noce_try_cmove_arith,
	noce_try_cmove_arith, noce_try_minmax, noce_try_abs,
	noce_try_sign_mask): Likewise.
	(if_convert): Check no_new_pseudos here.

	(cond_exec_process_if_block, noce_process_if_block, find_if_block):
	Remove prototypes.
	(struct noce_if_info): Add then_bb, else_bb, join_bb members.
	(noce_get_condition): Handle new then_else_reversed argument.
	(noce_init_if_info): Remove, fold into noce_find_if_block.
	(noce_process_if_block): Take a struct noce_if_info as the
	argument.  Don't set up one based on ce_if_info.  Update pointer
	references accordingly.
	(cond_move_process_if_block): Likewise.
	(process_if_block): Removed.
	(find_if_block): Removed.  Move functionality two new functions,
	noce_find_if_block and cond_exec_find_if_block.
	(noce_find_if_block): New function.  Be aware of IF-THEN-JOIN
	blocks and the symmetric IF-ELSE-JOIN case.
	(cond_exec_find_if_block): Also new function mostly based on old
	find_if_block and process_if_block.
	(find_if_header): Replace find_if_block call with separately
	guarded calls to noce_find_if_block and cond_exec_find_if_block.
	(find_cond_trap): Update noce_get_condition call.
	(dead_or_predicable): Likewise.
