Subject: vc4: When doing algebraic optimization into a MOV, use the right MOV.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e3efc4b02334897e0103f8cf926f376159ca1293;p=mesa.git

vc4: When doing algebraic optimization into a MOV, use the right MOV.

If there were src unpacks, changing to the integer MOV instead of float
(for example) would change the unpack operation.
