Subject: pan/midgard: Add OP_R27_ONLY helper
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f55a760d0c10cefe4725ab116c53272dc604d648;p=mesa.git

pan/midgard: Add OP_R27_ONLY helper

While load/store ops like st_vary can take an argument in either
r26/r27, ops like those for perspective projection must specifically
take their argument in r27.
