Bug ID: 115493 Summary: gcc.c-torture/execute/pr94734.c fails on MVE after gcc-15-1054-g202a9c8fe7d Product: gcc Version: 13.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: clyon at gcc dot gnu.org Target Milestone: --- Created attachment 58428 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=58428&action=edit Code generated before the offending GCC commit (works) As reported in https://linaro.atlassian.net/browse/GNU-1255, we are seeing FAIL: gcc.c-torture/execute/pr94734.c -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer -finline-functions execution test FAIL: gcc.c-torture/execute/pr94734.c -O3 -g execution test after g:202a9c8fe7d with GCC configured with: --disable-multilib --with-mode=thumb --with-arch=armv8.1-m.main+mve.fp+fp.dp --with-float=hard --target=arm-eabi and the testsuite executed with: qemu/-mthumb/-march=armv8.1-m.main+mve.fp+fp.dp/-mtune=cortex-m55/-mfloat-abi=hard/-mfpu=auto I'm attaching the annotated generated asm, the offending code is when calling if (baz (25, 4, 7) != 22) Maybe it's a problem with how we model predicates for MVE.
