@delcypher I am having a problem with my internal build after this change have gone in. Can you please help to determine what went wrong? Previously I was able to do the following:
$ cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_ASSERTIONS=On '-DLLVM_ENABLE_PROJECTS=clang;llvm;compiler-rt;clang-tools-extra;openmp;lld' -DCMAKE_C_COMPILER=/home/llvm/gcc/7.3.0/bin/gcc -DCMAKE_CXX_COMPILER=/home/llvm/gcc/7.3.0/bin/g++ -DLLVM_BINUTILS_INCDIR=/usr/include $LLVM_SRC $ ninja -j 20 $ ninja check-libomptarget check-openmp

lei added a comment to D22435: Fix pruned jump table basic blocks causing compilation failure (Bug 28102).
PR39124 has a reduced IR that seem to be the same issue this fixes. However I think Chri's suggested fix in PR28102 to remove the MBB references from the jump tables is a better way to go. Can you please give that a try?

For PPC this needs to be done for both tsan and msan.

lei added a comment to rL335514: [PowerPC] Fix incorrectly encoded wait instruction.
I am not sure why this has changed since ISA 2.07. But I have verified the new encoding on pwr8/pwr9 and that the old encoding produces an illegal instruction.
LGTM. Please feel free to fix the nit comments before committing.
