Need help debugging a PowerPC problem

Hi,

I need help debugging a problem a problem that only shows up on PowerPC with one of my commits in the generic CodeGen parts of llvm.
I’d apreciate it if someone with access to a PowerPC system could take a look at this: https://reviews.llvm.org/D23097

I’ll look tomorrow. What are the symptoms?

The bot only told me that the lnt tests "MultiSource/Benchmarks/mediabench/gsm/toast
" and "SingleSource/Benchmarks/Adobe-C++/loop_unroll.cpp" failed. They hopefully just have crashed or they computed results different from the expected reference results.

This is hopefully enough to reproduce with the cmake/lit test-suite mode:

mkdir build
cmake -GNinja -DCMAKE_C_COMPILER=/path/to/my/clang $TEST_SUITE_PATH
ninja toast loop_unroll
llvm-lit MultiSource/Benchmarks/mediabench/gsm/toast SingleSource/Benchmarks/Adobe-C++/loop_unroll.test

Thanks,
  Matthias
