Hi all,

Im porting a code from PowerPc to Intel, and I have some assembly code to port, my problem is at the cntlzw instruction, that count the number of leading zeros from a 32bits word.
So I want to know if the Intel has a similar intruction to do this or how would be the best way to port it.

Tks
Bruno
