Instead of checking for map_set.size() == 1, how about always doing
this
optimization for the last element of the map_set?
Something along the lines:
ASSERT(map_set.size() > 0);
int i = 0;
for (; i + 1 < map_set.size(); i++) {
...
__ B(eq, &success);
}
Handle<Map> map = map_set.at(i).handle();
__ CompareMap(map_reg, map);
deoptimize if ne
Done.
