Subject: x86emul: fix SIMD test overriding of VBROADCASTS{S,D}
X-Git-Tag: archive/raspbian/4.17.0-1+rpi1^2~33^2~1039
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=94334d854bd358bd1d9c61d5e3306e4d903b120b;p=xen.git

x86emul: fix SIMD test overriding of VBROADCASTS{S,D}

Despite their suffixes these aren't scalar instructions, and hence the
128- and 256-bit EVEX forms may not be used without AVX512VL. Gcc11 ends
up generating such instances for simd-sg.c.
