LLVM not building this morning (for me) on Mac OS X

Here’s the error:

(on a different machine, I get that error for i386 as well)

Here’s my cmake invocation:

$ cmake $LLVM/llvm -DLLVM_ENABLE_LIBCXX=On -DCMAKE_INSTALL_PREFIX=$LLVM/bin -DCMAKE_BUILD_TYPE=Release

Any ideas?

I think this was me. https://reviews.llvm.org/rL291068
I’ll roll back.

Rolled back in https://reviews.llvm.org/rL291141
Sorry for the breakage.

Thanks!

P.S. If you need someone to test out a patch, let me know.
