Subject: meson: disable sse4.1 optimizations with msvc
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d2cb0a59cedbc9f7b54b68c36e025f0c948ad846;p=mesa.git

meson: disable sse4.1 optimizations with msvc

There isn't an obvious command line switch here, /arch:AVX *might* be
the right thing, but meson doesn't know what to do here either and
leaves the -msse4.1 and -mstackrealign.
