示例1: assert
void XCoreFrameLowering::
processFunctionBeforeFrameFinalized(MachineFunction &MF,
RegScavenger *RS) const {
assert(RS && "requiresRegisterScavenging failed");
MachineFrameInfo *MFI = MF.getFrameInfo();
const TargetRegisterClass *RC = &XCore::GRRegsRegClass;
XCoreFunctionInfo *XFI = MF.getInfo<XCoreFunctionInfo>();
// Reserve slots close to SP or frame pointer for Scavenging spills.
// When using SP for small frames, we don't need any scratch registers.
// When using SP for large frames, we may need 2 scratch registers.
// When using FP, for large or small frames, we may need 1 scratch register.
if (XFI->isLargeFrame(MF) || hasFP(MF))
RS->addScavengingFrameIndex(MFI->CreateStackObject(RC->getSize(),
RC->getAlignment(),
