Author: rguenth Date: Sun Apr 27 16:27:08 2008 New Revision: 134730 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=134730 Log: 2008-04-27 Richard Guenther <[EMAIL PROTECTED]> PR tree-optimization/18754 PR tree-optimization/34223 * tree-pass.h (pass_complete_unrolli): Declare. * tree-ssa-loop-ivcanon.c (try_unroll_loop_completely): Print loop size before and after unconditionally of UL_NO_GROWTH in effect. Rewrite loop into loop closed SSA form if it is not already. (tree_unroll_loops_completely): Re-structure to iterate over innermost loops with intermediate CFG cleanups. Unroll outermost loops only if requested or the code does not grow doing so. * tree-ssa-loop.c (gate_tree_vectorize): Don't shortcut if no loops are available. (tree_vectorize): Instead do so here. (tree_complete_unroll): Also unroll outermost loops. (tree_complete_unroll_inner): New function. (gate_tree_complete_unroll_inner): Likewise. (pass_complete_unrolli): New pass. * tree-ssa-loop-manip.c (find_uses_to_rename_use): Only record uses outside of the loop. (tree_duplicate_loop_to_header_edge): Only verify loop-closed SSA form if it is available. * tree-flow.h (tree_unroll_loops_completely): Add extra parameter. * passes.c (init_optimization_passes): Schedule complete inner loop unrolling pass before the first CCP pass after final inlining. * gcc.dg/tree-ssa/loop-36.c: New testcase. * gcc.dg/tree-ssa/loop-37.c: Likewise. * gcc.dg/vect/vect-118.c: Likewise. * gcc.dg/Wunreachable-8.c: XFAIL bogus warning. * gcc.dg/vect/vect-66.c: Increase loop trip count. * gcc.dg/vect/no-section-anchors-vect-66.c: Likewise. * gcc.dg/vect/no-section-anchors-vect-69.c: Likewise. * gcc.dg/vect/vect-76.c: Likewise. * gcc.dg/vect/vect-outer-6.c: Likewise. * gcc.dg/vect/vect-outer-1.c: Likewise. * gcc.dg/vect/vect-outer-1a.c: Likewise. * gcc.dg/vect/vect-11a.c: Likewise. * gcc.dg/vect/vect-shift-1.c: Likewise. * gcc.target/i386/vectorize1.c: Likewise.
