From e60f103d2d3541e57a6ca8d788e959e03b615e5f Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Sat, 23 Jul 2011 03:10:19 +0000 Subject: Add a simple method for marking blocks with interference in and out. This method matches addLinks - All the listed blocks are considered to have interference, so they add a negative bias to their bundles. This could also be done by addConstraints, but that requires building a separate BlockConstraint array. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135844 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/SpillPlacement.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'lib/CodeGen/SpillPlacement.h') diff --git a/lib/CodeGen/SpillPlacement.h b/lib/CodeGen/SpillPlacement.h index 6952ad8009..9a4fc6dc97 100644 --- a/lib/CodeGen/SpillPlacement.h +++ b/lib/CodeGen/SpillPlacement.h @@ -96,6 +96,10 @@ public: /// live out. void addConstraints(ArrayRef LiveBlocks); + /// addPrefSpill - Add PrefSpill constraints to all blocks listed. + /// @param Blocks Array of block numbers that prefer to spill in and out. + void addPrefSpill(ArrayRef Blocks); + /// addLinks - Add transparent blocks with the given numbers. void addLinks(ArrayRef Links); -- cgit v1.2.3-70-g09d2
