Subject: Re: xor as a lazy comparison
Date: Wed, 27 Jul 2005 11:24:42 -0700 [thread overview]
Message-ID: <1122488682.7051.239374398@webmail.messagingengine.com> (raw)
Is not xor (^) typically compiled to a
one cycle instruction regardless of
requested optimization level? (May not
always have been the case on every
target architecture for != equality
tests.)

PS:
Anyone know where I can get
a waterproof, battery powered gps that will fit inside the handle of a Fenwick?
