With this suggestion, it always returns 0 instead of 1. Shouldn't pushl place 4 bytes on the stack? It translates into the instruction 0x6A (pushes only one byte). BTW, when I assemble it with as(1), there is always an extra instruction after my code, and it's a different one each time (and it's always one that effectively does nothing). Who ordered that? Is it because of alignment constraints in the ELF file? _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
