From: Jordan Justen Date: Fri, 20 Feb 2015 20:12:25 +0000 (-0800) Subject: i965/fs: Use fs_reg for CS/VS atomics pixel mask immediate data X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=49a938a265f5959c9b558995cc658f80acb6eb18;p=mesa.git i965/fs: Use fs_reg for CS/VS atomics pixel mask immediate data The brw_imm_ud will yield a HW_REG which then will introduce a barrier for certain optimization opportunities. No piglit regressions seen with gen8 (simd8vs).
