Subject: when negating scalar src args, use NEGATE_XYZW, not NEGATE_X
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=21454f86369e3290a4667037263399b1217d74b6;p=mesa.git

when negating scalar src args, use NEGATE_XYZW, not NEGATE_X

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