From 634abbf7b2e6ea21db30aafc0de9472ee31d4173 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Tue, 5 Oct 2010 10:25:22 -0700 Subject: i965: Also do constant propagation for the second operand of CMP. We could do the first operand as well by flipping the comparison, but this covered several CMPs in code I was looking at. --- src/mesa/drivers/dri/i965/brw_fs.cpp | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'src/mesa') diff --git a/src/mesa/drivers/dri/i965/brw_fs.cpp b/src/mesa/drivers/dri/i965/brw_fs.cpp index 0c9f17f8fd..914141a397 100644 --- a/src/mesa/drivers/dri/i965/brw_fs.cpp +++ b/src/mesa/drivers/dri/i965/brw_fs.cpp @@ -2607,6 +2607,11 @@ fs_visitor::propagate_constants() scan_inst->src[1] = inst->src[0]; } break; + case BRW_OPCODE_CMP: + if (i == 1) { + scan_inst->src[i] = inst->src[0]; + progress = true; + } } } -- cgit v1.2.3
