示例1: LowerSTACKMAP
// Lower a stackmap of the form:
// <id>, <shadowBytes>, ...
static void LowerSTACKMAP(MCStreamer &OS, StackMaps &SM,
const MachineInstr &MI, bool Is64Bit, const MCSubtargetInfo& STI) {
unsigned NumBytes = MI.getOperand(1).getImm();
SM.recordStackMap(MI);
// Emit padding.
// FIXME: These nops ensure that the stackmap's shadow is covered by
// instructions from the same basic block, but the nops should not be
// necessary if instructions from the same block follow the stackmap.
EmitNops(OS, NumBytes, Is64Bit, STI);
}
示例2: assert
void ARM64AsmPrinter::LowerSTACKMAP(MCStreamer &OutStreamer, StackMaps &SM,
const MachineInstr &MI) {
unsigned NumNOPBytes = MI.getOperand(1).getImm();
SM.recordStackMap(MI);
// Emit padding.
assert(NumNOPBytes % 4 == 0 && "Invalid number of NOP bytes requested!");
for (unsigned i = 0; i < NumNOPBytes; i += 4)
EmitToStreamer(OutStreamer, MCInstBuilder(ARM64::HINT).addImm(0));
