ARM ints

I can tell you one huge difference when it comes to ARM code, and it may apply to other architectures.

When you are using C in ARM, you should have all autos be 32 bits. If you use shorts or chars then after every operation it will do a shift-left, shift-right to either zero-extend or sign-extend the word to an int so that it is always a proper 32 bit int. This is of course horribly inefficient. If your autos...
