I guess the reason I choose .S is for debug-ability and maintenance if
I thought this work should be C I would have made it that. However you
can't debug these codes too well as inline asm.  I do agree that it
would be nice if I could have made these just straight C however much
like the ARM and ALPHA ports there is a place for straight assembler.

I/we really need to be able to debug this down to the last detail and
in C its just obfuscated too much.
