It uses 2 general registers, two mmx registers, and has only one branch. Can be modified easly to scan for another bytes. Here is the fasm macro: macro strlen Param { mov ecx, Param pxor mm1,mm1 sub ecx, 8 bucle: add ecx, 8 movq mm0, [ecx] pcmpeqb mm0,mm1 pmovmskb eax,mm0 test eax, eax jz bucle sub ecx, Param bsf eax, eax add eax, ecx } Posted: Tue Feb 07, 2006 7:54 pm erg0t Valuable expert Joined: Apr 08, 2005 Posts: 55 Location: Uruguay I optimized a little the rutine.
