Not using pld gives a speed penalty of 500-1000% (!) for ARMv5 :) > > I would suggest to use conditional compilation to separate between the > different ARM architectures. At least this is no good solution because it would require that we build two completly different releases. _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
