From eb9f040f0d07e2fa9b3b5ef46d5ee32511d28811 Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Mon, 14 Feb 2011 23:15:38 +0000 Subject: Move more fragments of spill weight calculation into CalcSpillWeights.h Simplify the spill weight calculation a bit by bypassing getApproximateInstructionCount() and using LiveInterval::getSize() directly. This changes the computed spill weights, but only by a constant factor in each function. It should not affect how spill weights compare against each other, and so it shouldn't affect code generation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125530 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/CalcSpillWeights.cpp | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'lib/CodeGen/CalcSpillWeights.cpp') diff --git a/lib/CodeGen/CalcSpillWeights.cpp b/lib/CodeGen/CalcSpillWeights.cpp index 6b57a07500..76bb3d148b 100644 --- a/lib/CodeGen/CalcSpillWeights.cpp +++ b/lib/CodeGen/CalcSpillWeights.cpp @@ -174,8 +174,7 @@ void VirtRegAuxInfo::CalculateWeightAndHint(LiveInterval &li) { totalWeight *= 0.5F; } - li.weight = totalWeight; - lis_.normalizeSpillWeight(li); + li.weight = normalizeSpillWeight(totalWeight, li.getSize()); } void VirtRegAuxInfo::CalculateRegClass(unsigned reg) { -- cgit v1.2.3
