示例1: IncrementTimeCounter
static void IncrementTimeCounter(Value* Inc, Value* calle, unsigned Index, GlobalVariable* Counters, IRBuilder<>& Builder, Value* Point)
{
LLVMContext &Context = Inc->getContext();
//In order to insert instruction after Point, we use the nextIns function.
Value* nextIns = getNextIns(Point);
Builder.SetInsertPoint(dyn_cast<Instruction>(nextIns));
// Create the getelementptr constant expression
std::vector<Constant*> Indices(2);
Indices[0] = Constant::getNullValue(Type::getInt32Ty(Context));
Indices[1] = ConstantInt::get(Type::getInt32Ty(Context), Index);
Constant *ElementPtr =
ConstantExpr::getGetElementPtr(Counters, Indices);
// Load, increment and store the value back.
// Use this formula: a = a + end_time - start_time
ArrayRef<Value*> args;
CallInst* Inc_end = Builder.CreateCall(calle, args, "");
Value* OldVal = Builder.CreateLoad(ElementPtr, "OldTimeCounter");
Value* TmpVal = Builder.CreateFSub(OldVal, Inc, "TmpTimeCounter");
Value* NewVal = Builder.CreateFAdd(TmpVal, Inc_end, "NewTimeCounter");
Builder.CreateStore(NewVal, ElementPtr);
