It's certainly possible to have an n32 mode a-la MIPS, but then you have to have 3 copies of all your libraries, when 2 were confusing enough. The Intel compiler has a funny mode in which it tries to implement ILP32 but extend pointers and longs when making system calls or calls to 64-bit libraries. It looks like an overly-heroic attempt to improve SPECint to me. -- greg _______________________________________________ Beowulf mailing list, [email protected] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
