Subject: ir_to_mesa: Fix up array indexing.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4a1bd916e79659abfa9dfdcf013eaff2daa66c29;p=mesa.git

ir_to_mesa: Fix up array indexing.

The grammar for array_reference_vec4_vec4 was set up wrong, so we
weren't generating instructions if necessary for the array index.
