--- Comment #6 from Dimitry Andric <dim@FreeBSD.org> ---
FWIW, clang defines __F16C__ for the following -march=3D settings:

alderlake, arrowlake, arrowlake-s, bdver2, bdver3, bdver4, broadwell, btver=
2,
cannonlake, cascadelake, clearwaterforest, cooperlake, core-avx-i, core-avx=
2,
emeraldrapids, gracemont, grandridge, graniterapids, graniterapids-d, haswe=
ll,
icelake-client, icelake-server, ivybridge, knl, knm, lunarlake, meteorlake,
pantherlake, raptorlake, rocketlake, sapphirerapids, sierraforest, skx,
skylake, skylake-avx512, tigerlake, x86-64-v3, x86-64-v4, znver1, znver2,
znver3, znver4.

I'm unsure if these names correspond exactly to what is in bsd.cpu.mk now.
Also, I don't see much use of the bsd.cpu.mk features in the src tree, but
maybe it is used more often in the ports tree?
