Subject: mesa: when negating scalar src args, use NEGATE_XYZW, not NEGATE_X
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bedb93e989340a2d65ed2fb28af7410983cb484d;p=mesa.git

mesa: when negating scalar src args, use NEGATE_XYZW, not NEGATE_X

This makes things easier on the back-end when generating GPU code.
