--- Comment #4 from Mark Millard <markmi at dsl-only.net> ---
(In reply to Pedro F. Giffuni from comment #3)

TARGET_ARCH=powerpc and TARGET_ARCH=powerpc64 of tier 2 are are still gcc 4.2.1
and libstdc++ based as far as built-in system compilers go.

Are they now libcxxrt based: Is libstdc++ now working on top of libcxxrt
instead of on libsupc++ ? (Clang is not sufficient yet for powerpc64 or
powerpc.)

powerpc64-xtoolchain-gcc and its powerpc64-gcc might be considered as covering
powerpc64, allowing libc++ (and libcxxrt). Are they considered as covering the
issue for powerpc64?

But there is no equivalent for powerpc (non-64).

[I do not claim to know much about the status for the likes of mips and sparc
but might some of them also have such issues?]

Should this report be left open but only for some tier 2 architectures?
