(tree_can_merge_blocks_p, remove_bb, tree_forwarder_block_p): Respect loop structure. * tree-flow.h (cleanup_tree_cfg_loop): Declare. (rewrite_into_loop_closed_ssa): Declaration changed. * tree-loop-linear.c (linear_transform_loops): Add argument to rewrite_into_loop_closed_ssa call. * tree-ssa-loop-ch.c (copy_loop_headers): Ditto. * tree-ssa-loop-im.c (move_computations): Ditto. * tree-ssa-loop.c (tree_loop_optimizer_init): Ditto. * tree-vectorizer.c (vectorize_loops): Ditto. * tree-optimize.c: Include cfgloop.h. (execute_todo): Choose whether to call cleanup_tree_cfg or cleanup_tree_cfg_loop. * tree-ssa-loop-ivcanon.c (canonicalize_loop_induction_variables, (tree_unroll_loops_completely): Enable cleanup_tree_cfg_loop call. * tree-ssa-loop-unswitch.c (tree_ssa_unswitch_loops): Enable cleanup_tree_cfg_loop call. * tree-ssa-loop-manip.c (find_uses_to_rename_bb): New function. (find_uses_to_rename, rewrite_into_loop_closed_ssa): Support work on part of cfg. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@96232 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/tree-loop-linear.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'gcc/tree-loop-linear.c') diff --git a/gcc/tree-loop-linear.c b/gcc/tree-loop-linear.c index 03333046129..860fafbd1de 100644 --- a/gcc/tree-loop-linear.c +++ b/gcc/tree-loop-linear.c @@ -272,7 +272,7 @@ linear_transform_loops (struct loops *loops) ... } } */ - if (!loop_nest->inner) + if (!loop_nest || !loop_nest->inner) continue; depth = 1; for (temp = loop_nest->inner; temp; temp = temp->inner) @@ -374,7 +374,7 @@ linear_transform_loops (struct loops *loops) free_df (); scev_reset (); rewrite_into_ssa (false); - rewrite_into_loop_closed_ssa (); + rewrite_into_loop_closed_ssa (NULL); #ifdef ENABLE_CHECKING verify_loop_closed_ssa (); #endif -- cgit v1.2.1
