llvm's bugzilla reports that the stack-handling SVR4 ABI violation for TARGET_ARCH=powerpc has been fixed r280705 (likely on trunk)! See below. This still leaves some problems in the C++ Itanium ABI exception handling support for both powerpc64 and powerpc. Also powerpc64 does not have softfloat available --which blocks libstand from building. Overall the META llvm bug 25780 still lists 3 "depends on" defects pending. One has a partial fix out for review.
