Subject: nv40: do full swtnl fallback when edge flags present.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=58b1bcaa094ed07a54bd7e4cdbddbcdcf1f629a7;p=mesa.git

nv40: do full swtnl fallback when edge flags present.

This isn't necessary, with some effort we can do this on the hw.  However,
until I encounter something "real" that uses them there's not a lot of
point.
