            Bug ID: 96858
           Summary: Many i386 testcases failed with different configured
                    gcc on different hosts.
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal

compare_tests result for default arch -march=3Dskylake-avx512 vs -march=3Dx=
86-64 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=3Dskylake-avx512, there would be lot=
s 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.=
