From f6811274e18a73e7ba84a820a28cc2549a4fab44 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Sat, 10 Oct 2009 08:27:29 +0000 Subject: [PATCH] add some WeakVH::operator='s. Without these, assigning a Value* to a WeakVH was constructing a temporary WeakVH (due to the implicit assignment operator). This avoids that cost. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83704 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/Support/ValueHandle.h | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/include/llvm/Support/ValueHandle.h b/include/llvm/Support/ValueHandle.h index d22b30af489..a8f2bdba552 100644 --- a/include/llvm/Support/ValueHandle.h +++ b/include/llvm/Support/ValueHandle.h @@ -54,6 +54,8 @@ private: PointerIntPair PrevPair; ValueHandleBase *Next; Value *VP; + + explicit ValueHandleBase(const ValueHandleBase&); // DO NOT IMPLEMENT. public: explicit ValueHandleBase(HandleBaseKind Kind) : PrevPair(0, Kind), Next(0), VP(0) {} @@ -131,6 +133,13 @@ public: WeakVH(const WeakVH &RHS) : ValueHandleBase(Weak, RHS) {} + Value *operator=(Value *RHS) { + return ValueHandleBase::operator=(RHS); + } + Value *operator=(const ValueHandleBase &RHS) { + return ValueHandleBase::operator=(RHS); + } + operator Value*() const { return getValPtr(); }
