[LLVMdev] PowerPC codegen experts looking for challenges?

at my paid job I am pushing the Clang/LLVM combo into evaluation (we
currently use a gcc3.4 generation toolchain). Since we produce for the
embedded domain we need a reliable
host (i.e. simulation i686) / target (PPC) dual setup. To this end I
almost succeeded grinding through our large(ish) codebase but found
some PPC snags.
I filed these bugs, complete with repro IR code:
I gather that the FreeBSD project is aiming at production use of LLVM
for PPC also, so these might have interesting fixes for those folks
Another thing, it appears that thread-global data is not yet supported
by the PPC backend. Is there a tracking bug for this or any plans to
fill this gap?
