Subject: i965: Delete send-from-GRF only opcodes from implied_mrf_writes().
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=192813e50ee8888a9012f5adce3003d0ca2aee22;p=mesa.git

i965: Delete send-from-GRF only opcodes from implied_mrf_writes().

These only exist post-Sandybridge, and always use send-from-GRF.
So inst->base_mrf will be -1, and we will have already returned 0.
