Subject: gk110/ir: fix imad sat/hi flag emission for immediate args
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1d708aacb7631833b0f04e704481854428f60ba3;p=mesa.git

gk110/ir: fix imad sat/hi flag emission for immediate args

According to nvdisasm both the immediate and non-imm cases use the same
bits. Both of these flags are quite rarely set though.
