Would you mind to avoid yasm and use gcc asm instead ?

I have no problem with yasm as such but gcc asm is more portable and
can be integrated with C code if we ever want that.
The existig yasm files are just ported from other projects and that way
to make porting changes forward and backward easier

If you prefer yasm, say so and ill review this.
