--- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> ---
Confirmed, we probably miss all:

      {"avx512vl",F_AVX512VL},
      {"avx512bw",F_AVX512BW},
      {"avx512dq",F_AVX512DQ},
      {"avx512cd",F_AVX512CD},
      {"avx512er",F_AVX512ER},
      {"avx512pf",F_AVX512PF},
      {"avx512vbmi",F_AVX512VBMI},
      {"avx512ifma",F_AVX512IFMA},
      {"avx5124vnniw",F_AVX5124VNNIW},
      {"avx5124fmaps",F_AVX5124FMAPS},
      {"avx512vpopcntdq",F_AVX512VPOPCNTDQ},
      {"avx512vbmi2", F_AVX512VBMI2},
      {"avx512vnni", F_AVX512VNNI},
      {"avx512bitalg", F_AVX512BITALG}

I can add all of these, buy I would like to have a comment of an i386 port
maintainer. Does it make sense to add all of them? And how should I prioritize
among them?
