I'm not sure I've completely understood the discussion (it has jumped
around a bit between mailing lists), but I think I agree with David
here. Architecture is a term that implies general common features, not
While hotspot and the rest of the jdk build is not currently in sync
with this terminology, in the common configure and makefiles we use the
terminology "target cpu" (which can be for instance "x86_64" or
"sparcv9" and "target cpu arch" (which can be for instance "x86" or
Regarding ppc, we currently define the target cpu arch "ppc" and two
target cpus, "ppc" and "ppc64".
Perhaps it would be more approriate to consider this a separate target
cpu ("ppc64le"), but not a separate target cpu architecture? But that
would be on the top-level -- I'm not sure how that would map properly to
the current hotspot build system.
