From f32a960fd32b32f84bb486458ccbc905af490da9 Mon Sep 17 00:00:00 2001 From: Eric Christopher Date: Wed, 15 Feb 2012 09:09:29 +0000 Subject: Add a way to replace a field inside a metadata node. This can be used to incrementally update a created node without needing a temporary node and RAUW. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150571 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/VMCore/Metadata.cpp | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'lib/VMCore/Metadata.cpp') diff --git a/lib/VMCore/Metadata.cpp b/lib/VMCore/Metadata.cpp index 5d6eb144c3..0fc2a2534d 100644 --- a/lib/VMCore/Metadata.cpp +++ b/lib/VMCore/Metadata.cpp @@ -87,6 +87,11 @@ static MDNodeOperand *getOperandPtr(MDNode *N, unsigned Op) { return reinterpret_cast(N+1)+Op; } +void MDNode::replaceOperandWith(unsigned i, Value *Val) { + MDNodeOperand *Op = getOperandPtr(this, i); + replaceOperand(Op, Val); +} + MDNode::MDNode(LLVMContext &C, ArrayRef Vals, bool isFunctionLocal) : Value(Type::getMetadataTy(C), Value::MDNodeVal) { NumOperands = Vals.size(); -- cgit v1.2.3-70-g09d2
