From 0f2e227d5ce6de4697ba94ed57f5ff7ca2d86f69 Mon Sep 17 00:00:00 2001 From: Connor Abbott Date: Mon, 3 Aug 2015 14:53:05 -0700 Subject: 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.
