Bug ID: 96858 Summary: Many i386 testcases failed with different configured gcc on different hosts. Product: gcc Version: 11.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c Assignee: unassigned at gcc dot gnu.org Reporter: crazylht at gmail dot com CC: hjl.tools at gmail dot com Target Milestone: --- Created attachment 49158 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=49158&action=edit compare_tests result for default arch -march=skylake-avx512 vs -march=x86-64 on i386 backend testcases For gcc version 11.0.0 20200831 (experimental) (GCC) If gcc is built with default config, there's no unexpected failures for all i386 backend testcases. but when gcc is built with --with-arch=skylake-avx512, there would be lots of unexpected failures --- Tests that now fail, but worked before (469 tests): --- It would be nice to adjust those testcases as we have regression tests for i386 backend with different gcc config.
