It will not be included if you  compile the RTL for an architecture that does not support this  instruction. The Cortex-A5 is an ARMv7 class cpu, so adding -Cparmv7  to your cross-options when building the RTL should work.Jonas_______________________________________________fpc-pascal maillist  -  fpc-pascal at lists.freepascal.orghttp://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
