Author: rguenth Date: Thu May 6 09:04:00 2010 New Revision: 159099 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=159099 Log: 2010-05-06 Richard Guenther <rguent...@suse.de> PR tree-optimization/43934 * tree-ssa-loop-im.c (movement_possibility): Handle PHI nodes. (stmt_cost): Likewise. (extract_true_false_args_from_phi): New helper. (determine_max_movement): For PHI nodes verify we can hoist them and compute their cost. (determine_invariantness_stmt): Handle PHI nodes. (move_computations_stmt): Likewise. Hoist PHI nodes in if-converted form using COND_EXPRs. (move_computations): Return TODO_cleanup_cfg if we hoisted PHI nodes. (tree_ssa_lim): Likewise. * tree-flow.h (tree_ssa_lim): Adjust prototype. * tree-ssa-loop.c (tree_ssa_loop_im): Return todo. * gcc.dg/tree-ssa/ssa-lim-9.c: New testcase.
