A more efficient optimization would use a forward for-loop. Modern processors are better suited for "normal" loops*, and the most compilers optimize them better. * For instance, the P4 has "data stream detection", which means that it can pre-cache data used in a first-to-last-byte manner, but not last-to-first-byte. -- Regards, Christian Iversen _______________________________________________ fpc-devel maillist - [email protected] http://lists.freepascal.org/mailman/listinfo/fpc-devel
