From: Connor Abbott Date: Mon, 3 Aug 2015 21:53:05 +0000 (-0700) Subject: i965/fs: don't propagate 64-bit immediates X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0f2e227d5ce6de4697ba94ed57f5ff7ca2d86f69;p=mesa.git i965/fs: don't propagate 64-bit immediates They can only be used with 1-src instructions, which practically (since we should've constant-propagated away all 1-src instructions with 64-bit immediates in NIR) means that they must be kept in separate MOV's and can't be propagated.
