Probably not. I have lots of experience with assembly in general, but not so much with x86. But the changes work and passes extensive tests, and some of them would be complex on any platform. I'm sure there will be cleanups and refinements needed, but I do know asm well enough to say that the fixes aren't horrific by any means - they're likely to be suboptimal, but supoptimal beats crashing or not compiling at all any day.
