From: Jason Ekstrand Date: Thu, 2 Oct 2014 23:04:57 +0000 (-0700) Subject: i965/fs: Use the correct base_mrf for spilling pairs in SIMD8 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=493bfa54a57e2feddd887ba0ec3d5ef139e82f3b;p=mesa.git i965/fs: Use the correct base_mrf for spilling pairs in SIMD8 Before, we were hard-coding the base_mrf based on dispatch width not number of registers spilled at a time. This caused us to emit instructions with a base_mrf or 14 and a mlen of 3 so we used the magical non-existant m16 register. This fixes the problem.
