示例1: scratch
void
MacroAssemblerX64::branchValueIsNurseryObject(Condition cond, ValueOperand value, Register temp,
Label* label)
{
MOZ_ASSERT(cond == Assembler::Equal || cond == Assembler::NotEqual);
const Nursery& nursery = GetJitContext()->runtime->gcNursery();
// Avoid creating a bogus ObjectValue below.
if (!nursery.exists())
return;
// 'Value' representing the start of the nursery tagged as a JSObject
Value start = ObjectValue(*reinterpret_cast<JSObject*>(nursery.start()));
ScratchRegisterScope scratch(asMasm());
