llvm's bugzilla reports that the stack-handling SVR4 ABI violation for = TARGET_ARCH=3Dpowerpc 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.
