Subject: microsoft/compiler: Support up to shader model 6.5
X-Git-Tag: upstream/22.3.5~4253
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d4b964b546405fe3d9009fe3e19ab1e453251f63;p=platform%2Fupstream%2Fmesa.git

microsoft/compiler: Support up to shader model 6.5

We don't actually use any of the new features, but that's okay, it's
still valid DXIL at the higher shader models.
