With this change, all of MultiSource/Applications passes on Darwin/X86 under FastISel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55982 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/SelectionDAG/FastISel.cpp | 2 ++ 1 file changed, 2 insertions(+) diff --git a/lib/CodeGen/SelectionDAG/FastISel.cpp b/lib/CodeGen/SelectionDAG/FastISel.cpp index 33f4591b66a..d73bce74e6b 100644 --- a/lib/CodeGen/SelectionDAG/FastISel.cpp +++ b/lib/CodeGen/SelectionDAG/FastISel.cpp @@ -39,6 +39,8 @@ unsigned FastISel::getRegForValue(Value *V) { MBB->getParent()->getConstantPool()); // Don't cache constant materializations.
