Do you think people will bother? Nobody mentioned to the original poster so far: - that the used FPC is outdated - that only -O2 is used instead of -O3 (or -O4 with 3.0.0) - that even FPC 2.6.4 has a -Ooloopunroll option which is never enabled by default and which is worth a try I do not know if the points above really effect the example, but it tells me enough not to bother either :) _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
