From 977a76fbb6ea1b87dfd7fbbe2ae2afb63e982ff3 Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Wed, 13 Feb 2008 22:28:48 +0000 Subject: Simplify some logic in ComputeMaskedBits. And change ComputeMaskedBits to pass the mask APInt by value, not by reference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47096 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/CodeGen/SelectionDAG.h | 2 +- include/llvm/Target/TargetLowering.h | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) (limited to 'include') diff --git a/include/llvm/CodeGen/SelectionDAG.h b/include/llvm/CodeGen/SelectionDAG.h index 560e0fca13..22487dd5c3 100644 --- a/include/llvm/CodeGen/SelectionDAG.h +++ b/include/llvm/CodeGen/SelectionDAG.h @@ -556,7 +556,7 @@ public: /// bitsets.
