From a92afc18a8ff72b905902d75a2a4920d5438ca0c Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Wed, 3 Aug 2011 23:16:09 +0000 Subject: Enable compact region splitting by default. This helps generate better code in functions with high register pressure. The previous version of compact region splitting caused regressions because the regions were a bit too large. A stronger negative bias applied in r136832 fixed this problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136836 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/RegAllocGreedy.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/CodeGen/RegAllocGreedy.cpp') diff --git a/lib/CodeGen/RegAllocGreedy.cpp b/lib/CodeGen/RegAllocGreedy.cpp index 4c130d0..87b12c6 100644 --- a/lib/CodeGen/RegAllocGreedy.cpp +++ b/lib/CodeGen/RegAllocGreedy.cpp @@ -52,7 +52,7 @@ STATISTIC(NumGlobalSplits, "Number of split global live ranges"); STATISTIC(NumLocalSplits, "Number of split local live ranges"); STATISTIC(NumEvicted, "Number of interferences evicted"); -cl::opt CompactRegions("compact-regions"); +cl::opt CompactRegions("compact-regions", cl::init(true)); static RegisterRegAlloc greedyRegAlloc("greedy", "greedy register allocator", createGreedyRegisterAllocator); -- cgit v1.1
