示例1: EmitInstruction
void MCObjectStreamer::EmitInstruction(const MCInst &Inst,
const MCSubtargetInfo &STI) {
// @LOCALMOD-BEGIN
if (getAssembler().isBundlingEnabled() &&
getAssembler().getBackend().CustomExpandInst(Inst, *this)) {
return;
}
// @LOCALMOD-END
MCStreamer::EmitInstruction(Inst, STI);
MCSectionData *SD = getCurrentSectionData();
SD->setHasInstructions(true);
// Now that a machine instruction has been assembled into this section, make
// a line entry for any .loc directive that has been seen.
MCLineEntry::Make(this, getCurrentSection().first);
// If this instruction doesn't need relaxation, just emit it as data.
MCAssembler &Assembler = getAssembler();
if (!Assembler.getBackend().mayNeedRelaxation(Inst)) {
EmitInstToData(Inst, STI);
return;
}
// Otherwise, relax and emit it as data if either:
// - The RelaxAll flag was passed
// - Bundling is enabled and this instruction is inside a bundle-locked
// group. We want to emit all such instructions into the same data
// fragment.
if (Assembler.getRelaxAll() ||
(Assembler.isBundlingEnabled() && SD->isBundleLocked())) {

}
// Otherwise emit to a separate fragment.

// Scan for values.
