示例1: IonFrameIterator
IonBailoutIterator::IonBailoutIterator(const IonActivationIterator &activations,
BailoutStack *bailout)
: IonFrameIterator(activations),
machine_(bailout->machine())
{
uint8_t *sp = bailout->parentStackPointer();
uint8_t *fp = sp + bailout->frameSize();
current_ = fp;
type_ = IonFrame_OptimizedJS;
topFrameSize_ = current_ - sp;
topIonScript_ = script()->ion;
if (bailout->frameClass() == FrameSizeClass::None()) {
snapshotOffset_ = bailout->snapshotOffset();
return;
}
// Compute the snapshot offset from the bailout ID.
IonActivation *activation = activations.activation();
JSCompartment *jsCompartment = activation->compartment();
IonCompartment *ionCompartment = jsCompartment->ionCompartment();
IonCode *code = ionCompartment->getBailoutTable(bailout->frameClass());
uintptr_t tableOffset = bailout->tableOffset();
uintptr_t tableStart = reinterpret_cast<uintptr_t>(code->raw());
JS_ASSERT(tableOffset >= tableStart &&
tableOffset < tableStart + code->instructionsSize());
JS_ASSERT((tableOffset - tableStart) % BAILOUT_TABLE_ENTRY_SIZE == 0);
uint32_t bailoutId = ((tableOffset - tableStart) / BAILOUT_TABLE_ENTRY_SIZE) - 1;
JS_ASSERT(bailoutId < BAILOUT_TABLE_SIZE);
snapshotOffset_ = topIonScript_->bailoutToSnapshot(bailoutId);
