[llvm] r329355 - [RuntimeDyld][PowerPC] Add a test case for r329335.

[Galina Kistanova via llvm-commits]

Hello Lang,

This commit added broken test to one of our builders:
http://lab.llvm.org:8011/builders/llvm-clang-x86_64-expensive-checks-win/builds/8885

Failing Tests:
. . .
    LLVM :: ExecutionEngine/RuntimeDyld/PowerPC/ppc64_elf.s
. . .
Please have a look?

The builder was red and did not send notifications.

Thanks

Galina
