Subject: vc4: R4 is not a valid register for clamped direct texturing.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=507f3e708cbd10a4272aeffa0f066f1a80b48239;p=mesa.git

vc4: R4 is not a valid register for clamped direct texturing.

Our array only goes to R3, and R4 is a special case that shouldn't be
used.
