Great. (seriously) Using 16-byte stack alignment? More? Keeping .text in the low 2 GB? Other stuff? Keeping anything in a 48-bit range? (One less opcode than full 64-bit) That TOC? Still using "funtion pointers" that aren't? Anything left to improve? BTW, failure to have a prototype in scope had ought to be an error these days. I think C99 allows that.
