Surely not. It checks 16 bytes. The first 'iteration' compares offset 1 to 0; the 2nd, 2 with 1, and so on, until the 15th 'compare' checks offset 15 with offset 14.
In total, offset 0 would be compared (for equality) with all bytes up to offset 15. 0 .. 15 = 16. Trivially, CLC 1(1,R5),0(R5) compares whether the two bytes are the same. > -----Original Message----- > From: [email protected] > Sent: Thu, 30 Sep 2010 15:35:49 -0400 > To: [email protected] > Subject: Re: Help jog my memory (16-bytes the same) > > This statement checks only 15 bytes, not 16 bytes (starting at the > second byte pointed to by R5).
