Subject: x86: consistently use scalar_mode for AVX512-FP16 scalar insns
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=928c8d70c82feea45683b43e324cd2079d4ee31d;p=binutils-gdb.git

x86: consistently use scalar_mode for AVX512-FP16 scalar insns

For some reason the original AVFX512F insns were not taken as a basis
here, causing unnecessary divergence. While not an active issue, it is
still relevant to note that OP_XMM() has special treatment of e.g.
scalar_mode (marking broadcast as invalid). Such would better be
consistent for all sufficiently similar insns.
