Potentially. It allows the compiler to use x64 features such as W^X, which relies on there being an NX bit in the page table entry. This wasn't part of the x86 design, but was added by AMD for the x64. Then Intel backported it to the Prescott architecture for the Pentium-4. But unless you can guarantee you'll never run on pre-Prescott chips, you can't rely on W^X. True, W^X is an OS-level feature and not a GnuPG feature. But it should work as an example of how the two instruction sets could be different in ways important for computer security. _______________________________________________ Gnupg-users mailing list [email protected] http://lists.gnupg.org/mailman/listinfo/gnupg-users
