From: "rguenth at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug bootstrap/97502] [11 Regression] PGO bootstrap failure on s390x-linux with -march=z13 starting with r11-3426 Date: Tue, 20 Oct 2020 13:53:32 +0000 [thread overview] Message-ID: <bug-97502-4-3FCTi3DFdM@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-97502-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97502 --- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- So the following is problematic: vector(16) <signed-boolean:8> _12; vector(16) <signed-boolean:8> _14; vector(16) <signed-boolean:8> _32; _14 = vect__1.7_3 != { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }; _12 = vect__2.10_15 == { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }; _32 = VEC_COND_EXPR <_12, _14, { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }>; using a VEC_COND_EXPR to combine two vector bools to another vector bool. The above could be folded to ~_12 & _14 instead.
