            Bug ID: 26133
           Summary: Incorrect need_arch_feature_F16C
           Product: glibc
           Version: 2.32
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: hjl.tools at gmail dot com
                CC: drepper.fsp at gmail dot com
  Target Milestone: ---
            Target: i386,x86-64

cpu-features.h has

#define need_arch_feature_F16C        0

Since F16C requires AVX, it is usable only when AVX is usable.
