From 5dd9c2e9aea7294c184609aff7f2fe82eaea4eb0 Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Thu, 25 Sep 2008 17:22:52 +0000 Subject: [PATCH] Support for i1 XOR in FastISel. It is actually safe because i1 operands are assumed to already by zero-extended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56615 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/SelectionDAG/FastISel.cpp | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/lib/CodeGen/SelectionDAG/FastISel.cpp b/lib/CodeGen/SelectionDAG/FastISel.cpp index 254b1fe42cc..dcb30ad1882 100644 --- a/lib/CodeGen/SelectionDAG/FastISel.cpp +++ b/lib/CodeGen/SelectionDAG/FastISel.cpp @@ -135,10 +135,11 @@ bool FastISel::SelectBinaryOp(User *I, ISD::NodeType ISDOpcode) { // under the assumption that i64 won't be used if the target doesn't // support it. if (!TLI.isTypeLegal(VT)) { - // MVT::i1 is special.
