gcc 11 with flags + i686 x86/{sse,sse2} test_simde_mm_cvt* failures
On the latest master branch commit: df63f88a364da6be3963b4924c327b12f88d7748 with gcc 11 with the following flags on Fedora rawhide (= 35), I faced the following failures. This failures do not happen with the gcc 11 without flags (no CFLAGS and no CXXFLAGS).
Could you take a look? Thanks.

This failures also do not happen with the gcc 11 + only -O2 flags (CFLAGS="-O2" CXXFLAGS="-O2").
This failures also do not happen with the gcc 11 + only -O2 flags (CFLAGS="-O2" and no CXXFLAGS="-O2").
They don't? i686 is a mess on my system, even without any optimization flags. Maybe because I'm just running the i686 executables on an x86_64 system… I'll have to try installing an i686 VM to see if it's any different.
Yes, they don't. OK. I will share the full log of the 2 cases (-O2 + other flags vs only -O2) later.
Here is the full-log by building the simde RPM spec file.
In the result log,
- The test case "=== 1.2. tests on gcc with O2 flag ===" is with only -O2 flag.
- The test case "=== 1.3. tests on gcc with flags macro ===" is with -O2 + other flags.
You can see only the "1.3" shows the failures.
I noticed in the above full-log by the builds, which I executed on minutes ago, the gcc version is 11.0.1, not 11.0.0.

@junaruga can you re-run your tests against the latest code?
Would be nice to have a Dockefile that reproduced this
Thanks!
