buildbot failure in LLVM on llvm-mips-linux

This buildbot seems to have been failing continuously for a couple of weeks now ( http://lab.llvm.org:8011/builders/llvm-mips-linux/builds/14658 ) - is anyone watching it/caring about it?

David,

Yes, we have people looking into this. The board it was originally on
has failed. We moved it to a similar board, but that one has failed as
well. Now we're on a third board that only has two cores and we're
trying to get it working on that. Since this latest board only has two
cores, it will run slower and it will need to have the -j6 changed to -j2.

The failure is a bit odd. LLVM is ignoring $PWD because it doesn’t have the same inode as ‘.’. This causes the test failure because DW_AT_comp_dir and $PWD differ. However, $PWD and ‘.’ should be the same inode since $PWD is a symlink to the current directory and stat() looks through symlinks.

Since this latest board only has two cores, it will run slower and it will need to have the -j6 changed to -j2.

I’ll make that change in the morning.

This builder is now green. The problem turned out to be that the symlink was actually pointing at the path the original board was using and the test wasn’t re-creating it.

Thanks!

Hopefully we can figure out some way to make this sort of thing more
transparent/less spammy for the community of developers when an issue is
alerady known/triaged/owned by someone for investigation. (see Renato's
recent thread to llvm-dev about possibly improvements/ways to address some
of these buildbot use cases/situations)
