示例1: if
MIRType
TypeInferenceOracle::elementWrite(UnrootedScript script, jsbytecode *pc)
{
StackTypeSet *objTypes = script->analysis()->poppedTypes(pc, 2);
MIRType elementType = MIRType_None;
unsigned count = objTypes->getObjectCount();
for (unsigned i = 0; i < count; i++) {
if (objTypes->getSingleObject(i))
return MIRType_None;
if (TypeObject *object = objTypes->getTypeObject(i)) {
types::HeapTypeSet *elementTypes = object->getProperty(cx, JSID_VOID, false);
if (!elementTypes)
return MIRType_None;
MIRType type = getMIRType(elementTypes);
if (type == MIRType_None)
return MIRType_None;
if (elementType == MIRType_None)
elementType = type;
else if (elementType != type)
return MIRType_None;
}
}
return elementType;
}示例2:
bool
TypeInferenceOracle::propertyReadIdempotent(HandleScript script, jsbytecode *pc, HandleId id)
{
if (script->analysis()->getCode(pc).notIdempotent)
return false;
if (id != MakeTypeId(cx, id))
return false;

if (types->getSingleObject(i))
return false;
if (TypeObject *obj = types->getTypeObject(i)) {
if (obj->unknownProperties())
return false;
// Check if the property has been reconfigured or is a getter.
HeapTypeSet *propertyTypes = obj->getProperty(cx, id, false);
if (!propertyTypes || propertyTypes->isOwnProperty(cx, obj, true))
return false;
}
