--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Could you try this patch which disables ifcombine (since there is a known miscompile in some cases caused by one of the patches in the range you listed, see PR 118409): ``` [apinski@xeond2 gcc]$ git diff tree-ssa-ifcombine.cc diff --git a/gcc/tree-ssa-ifcombine.cc b/gcc/tree-ssa-ifcombine.cc index f791994e3b9..b3812123631 100644 --- a/gcc/tree-ssa-ifcombine.cc +++ b/gcc/tree-ssa-ifcombine.cc @@ -1379,6 +1379,7 @@ pass_tree_ifcombine::execute (function *fun) basic_block *bbs; bool cfg_changed = false; int i; + return 0; bbs = single_pred_before_succ_order (); calculate_dominance_info (CDI_DOMINATORS); ``` This is more to see if something is being miscompiled by ifcombine.
