in thread Module for 128-bit integer math?

You could try to go down the interesting route of compiling a Perl with an IV size of 128 bit, but that'll likely make the XS libraries crash and burn as they likely suppose that sizeof(void *) == sizeof(int) == sizeof(IV). But it might be worth a try to just see whether Perl compiles and tests OK with an enlarged IV.

    I don't think that would work because there are no 128-bit native C data types in the compiler.

    The support is via the XMM registers, and they require special treatment.

      Hey, if there's a developer version of GCC that does handle 128-bit integers like salva mentions down below in 887024 then could this work? Or likely to be too experimental or still too many other problems?

        I've read and responded to salva's very useful post.

        Are we done now?
