Subject: nv50/ir: fix imad emission when dst == src2
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=603d28f32c1083921ea9d54a0a606dd832e44aaa;p=mesa.git

nv50/ir: fix imad emission when dst == src2

Commit fb63df22151f added 4-byte mad support, but only supported
emission for floats. Disable it for ints for now.
