(Reposting the request to llvm-dev for better visibility)
I had to revert a change today, due to test errors on some buildbots. The errors did seem to only happen on the ppc64be and aarch64 buildbots. I don't have access to a ppc64be setup to test on, but I've tried to build and run in a setup very similar to the one on the aarch64 buildbot, but I can't reproduce the errors there.
The failing test was present in SVN r351801 to r351810, in test/tools/llvm-objcopy/COFF/add-gnu-debuglink.test. The failing test looked like this:
Can someone with access to the buildbots (or similar systems) help reproducing the issue? The test output files and the full output of the commands in the tests would be helpful.
