It's failing with "unresolved external symbol" and I kind of expected that it would. Torque is, to the best of my understanding, a closed-world compiler (i.e., needs to see all inputs) and therefore not amenable to a staggered approach.

I think the best way to approach this is by teaching torque to read from a resource file (a file that lists all the inputs) but that patch should be sent to upstream V8 first if the diff is more than a few lines because I don't want to carry complex patches.
