Same issue, osX github CI

It seems i686-unknown-linux-gnu github CI has some problems?

[minybot]

stdarch-test bugs?

[Amanieu]

_mm_cvt_roundi64_ss and _mm_cvt_roundsi64_ss are only available on x86_64, not x86.

[Amanieu]

Check against the Clang headers to see which intrinsics are wrapped in #ifdef __x86_64__.

Thanks. Before we put "epi64" and "pd" tests on x86_64. Should we move those back to x86?

[Amanieu]

The tests for intrinsics defined in x86 should be in x86, and the tests for intrinsics defined in x86_64 should be in x86_64. That way x86_64 runs tests in both x86 and x86_64.

[Amanieu]

Considering how large these files are already, maybe you should split the tests off into a separate file.

Yes, but all test will be around 20000 lines.
The intrinsic for avx512f is still around 40000 lines.
Do you think which one is better? (one 60000 lines file or two 40000 and 20000 line files)

[Amanieu]

I guess it doesn't really make a difference.
