From 2f9dac721d6b015fd16730bd51bffc86e29e6fdf Mon Sep 17 00:00:00 2001 From: Victor Hernandez Date: Mon, 7 Dec 2009 19:36:34 +0000 Subject: Introduce the "@llvm.dbg.value" debug intrinsic. The semantics of llvm.dbg.value are that starting from where it is executed, an offset into the specified user source variable is specified to get a new value. An example: call void @llvm.dbg.value(metadata !{ i32 7 }, i64 0, metadata !2) Here the user source variable associated with metadata #2 gets the value "i32 7" at offset 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90788 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Analysis/DebugInfo.cpp | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) (limited to 'lib/Analysis/DebugInfo.cpp') diff --git a/lib/Analysis/DebugInfo.cpp b/lib/Analysis/DebugInfo.cpp index 4a012ce484..74d9e1e179 100644 --- a/lib/Analysis/DebugInfo.cpp +++ b/lib/Analysis/DebugInfo.cpp @@ -1050,6 +1050,35 @@ Instruction *DIFactory::InsertDeclare(Value *Storage, DIVariable D, return CallInst::Create(DeclareFn, Args, Args+2, "", InsertAtEnd); } +/// InsertValue - Insert a new llvm.dbg.value intrinsic call. +Instruction *DIFactory::InsertValue(Value *V, Value *Offset, DIVariable D, + Instruction *InsertBefore) { + assert(V && "no value passed to dbg.value"); + assert(Offset->getType() == Type::getInt64Ty(V->getContext()) && + "offset must be i64"); + if (!ValueFn) + ValueFn = Intrinsic::getDeclaration(&M, Intrinsic::dbg_value); + + Value *Elts[] = { V }; + Value *Args[] = { MDNode::get(V->getContext(), Elts, 1), Offset, + D.getNode() }; + return CallInst::Create(ValueFn, Args, Args+3, "", InsertBefore); +} + +/// InsertValue - Insert a new llvm.dbg.value intrinsic call. +Instruction *DIFactory::InsertValue(Value *V, Value *Offset, DIVariable D, + BasicBlock *InsertAtEnd) { + assert(V && "no value passed to dbg.value"); + assert(Offset->getType() == Type::getInt64Ty(V->getContext()) && + "offset must be i64"); + if (!ValueFn) + ValueFn = Intrinsic::getDeclaration(&M, Intrinsic::dbg_value); + + Value *Elts[] = { V }; + Value *Args[] = { MDNode::get(V->getContext(), Elts, 1), Offset, + D.getNode() }; + return CallInst::Create(ValueFn, Args, Args+3, "", InsertAtEnd); +} //===----------------------------------------------------------------------===// // DebugInfoFinder implementations. -- cgit v1.2.3
