commit b989a899bb39d05a6ee9b2dec87bd5223aa10543
Author: Fangrui Song <maskray@google.com>
Date:   Sun Oct 10 14:38:00 2021 -0700

    x86: Define __HAVE_FLOAT128 for Clang and use __builtin_*f128 code path
    
    Clang supports __builtin_fabsf128 (despite not supporting _Float128) but
    _not _builtin_fabsq.
    By falling back to `typedef __float128 _Float128;`, the float128 code
    will be buildable with Clang.

commit 0d61efe1f49a12db89d827f73ad1c94ba5747a93
Author: Fangrui Song <maskray@google.com>
Date:   Sun Oct 10 14:38:00 2021 -0700

    x86: Define __HAVE_FLOAT128 for Clang and use __builtin_*f128 code path
    
    Clang supports __builtin_fabsf128 (despite not supporting _Float128) but
    _not _builtin_fabsq.
    By falling back to `typedef __float128 _Float128;`, the float128 code
    will be buildable with Clang.

commit f7fa7d334ec5dc15379735390f7071e2f2218e4e

Date:   Sun Oct 10 14:38:00 2021 -0700

    x86: Define __HAVE_FLOAT128 for Clang and use __builtin_*f128 code path
    
    Clang supports __builtin_fabsf128 (despite not supporting _Float128) but
    _not _builtin_fabsq.
    By falling back to `typedef __float128 _Float128;`, the float128 code
    will be buildable with Clang.
