2015-10-29	[PATCH][PR tree-optimization/67892] Use FSM threader to handle backedges	Jeff Law	1	-1/+1
	PR tree-optimization/67892 * tree-ssa-threadedge.c (simplify_controL_stmt_condition): Fix typo in comment. (thread_through_normal_block): If we have seen a backedge, then do nothing. No longer call find_jump_threads_backwards here. (thread_across_edge): Use find_jump_threads_backwards to find jump threads if the old style threader was not successful. * tree-ssa-threadbackward.c (get_gimple_control_stmt): Use gsi_last_nondebug_bb. Return NULL if the block does not end with a control statement. (find_jump_threads_backwards): Setup code moved here from tree-ssa-threadedge.c::thread_through_normal_block. Accept single edge argument instead of name & block. * tree-ssa-threadbackward.h (find_jump_threads_backwards): Update prototype. PR tree-optimization/67892 * gcc.dg/tree-ssa/pr21417: Update expected output. * gcc.dg/tree-ssa/ssa-dom-thread-2b.c: Likewise. From-SVN: r229538
2015-10-11	[PATCH] Refactoring FSM bits into their own file	Jeff Law	1	-0/+25
	[PATCH] Refactoring FSM bits into their own file * tree-ssa-threadedge.c (fsm_find_thread_path): Moved from here into tree-ssa-threadbackward.c. (fsm_find_control_statement_thread_paths): Likewise. (thread_through_normal_block): Break out FSM bits and move them into a new function in tree-ssa-threadbackward.c. Call new function instead. Minimize header file usage. * tree-ssa-threadbackward.h: New file. * tree-ssa-threadbackward.c: Likewise. * Makefile.in (OBJS): Add tree-ssa-threadbackward.o From-SVN: r228700
