From: "glisse at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/54346] combine permutations Date: Tue, 11 Oct 2022 06:21:53 +0000 [thread overview] Message-ID: <bug-54346-4-jQQrWnJwBR@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-54346-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54346 --- Comment #6 from Marc Glisse <glisse at gcc dot gnu.org> --- The log says that this breaks tree-ssa/forwprop-19.c, but I don't see any xfail or anything. Does it only fail because gimple-simplify leaves some dead code around, so you could update the test to scan the next DCE pass dump instead of forwprop1? Or are we missing a transformation that just detects a VEC_PERM_EXPR with an identity permutation?
