示例1: createCmpXchgInstFun
static void createCmpXchgInstFun(IRBuilder<> &Builder, Value *Addr,
Value *Loaded, Value *NewVal,
AtomicOrdering MemOpOrder,
Value *&Success, Value *&NewLoaded) {
Value* Pair = Builder.CreateAtomicCmpXchg(
Addr, Loaded, NewVal, MemOpOrder,
AtomicCmpXchgInst::getStrongestFailureOrdering(MemOpOrder));
Success = Builder.CreateExtractValue(Pair, 1, "success");
NewLoaded = Builder.CreateExtractValue(Pair, 0, "newloaded");
}示例2: if
Value*
code_emitter::convert_complex_return_value (Value *result)
{
/* The result is complex, whose representation
differs between archs, and we need to transform
it into another arch-dependent
representation. */
if (sizeof(gpointer) == 4)
{
Value *local = complex_copy_var;
Value *local_ptr = builder->CreateBitCast(local, PointerType::getUnqual(Type::Int64Ty));
builder->CreateStore(result, local_ptr);
result = builder->CreateLoad(local);
}
else if (sizeof(gpointer) == 8)
result = builder->CreateExtractValue(result, 0);
