From b4566a999970b514d7c6973d99e293a6625d3f70 Mon Sep 17 00:00:00 2001 From: Andrew Trick Date: Wed, 22 Feb 2012 06:08:11 +0000 Subject: Initialize SUnits before DAG building. Affect on SD scheduling and postRA scheduling: Printing the DAG will display the nodes in top-down topological order. This matches the order within the MBB and makes my life much easier in general. Affect on misched: We don't need to track virtual register uses at all. This is awesome. I also intend to rely on the SUnit ID as a topo-sort index. So if A < B then we cannot have an edge B -> A. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151135 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/LatencyPriorityQueue.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/CodeGen/LatencyPriorityQueue.cpp') diff --git a/lib/CodeGen/LatencyPriorityQueue.cpp b/lib/CodeGen/LatencyPriorityQueue.cpp index 0eb009ddac..0578229432 100644 --- a/lib/CodeGen/LatencyPriorityQueue.cpp +++ b/lib/CodeGen/LatencyPriorityQueue.cpp @@ -46,7 +46,7 @@ bool latency_sort::operator()(const SUnit *LHS, const SUnit *RHS) const { // Finally, just to provide a stable ordering, use the node number as a // deciding factor. - return LHSNum < RHSNum; + return RHSNum < LHSNum; } -- cgit v1.2.3-70-g09d2
