I'm not entirely clear on what you're asking.

For x86_64-nacl, x32 will be the primary model (and the only one supported
by gcc and glibc, when that work is eventually done).  So it just seemed
right that bare x86_64-nacl-as default to --x32.

But there are existing binaries from a past toolchain port (never
integrated upstream, and not very good quality) that use ELFCLASS64, so it
seems worthwhile that target=x86_64-nacl binutils know how to handle those
too.  Hence, target=x86_64-nacl and target=i?86-nacl builds have all three
BFD target flavors.

Does that answer your question?


Thanks,
