Being new to gcc, I'm not particularly familiar with the __builtins available (for example: while finding ffs was pretty straightforward, finding the match for BitScanReverse took more creativity). Is this something you know well? Also (exposing my ignorance here), how do the built-ins for gcc get created? If (as I'm saying to kai) the definitions in winnt.h are wrong, could that same code be what's used in the __builtins? dw ------------------------------------------------------------------------------ Own the Future-Intel(R) Level Up Game Demo Contest 2013 Rise to greatness in Intel's independent game demo contest.
