clang/lnt buildbot on F20 "lnt: error: no such option: -m" ...

Hi
Since the buildbot host was updated to Fedora F20 levels, the clang
buildbot has been failing with the following:

$ /home/clangbuild/clang-ppc64-1/lnt.venv/bin/lnt runtest --verbose --submit http://llvm.org/perf/submitRun --commit=1 nt --sandbox nt --no-timestamp --cc /home/clangbuild/clang-ppc64-1/llvm.install.1/bin/clang --cxx /home/clangbuild/clang-ppc64-1/llvm.install.1/bin/clang++ --without-llvm --test-suite /home/clangbuild/clang-ppc64-1/test-suite --no-machdep-info chinook-clangslave1__O3-plain --multisample=3 -mcpu=native

lnt: error: no such option: -m

I have removed the clang-ppc64-1 subdirectory, and the buildbot has
entirely recreated and refreshed it's contents. I'm wondering if
there is a python version or other incompatibility that has been
introduced here, but it's not obvious to me.

Any suggestions on how to (easily?) identify the issue?
Host is currently running python-2.7.5-9.fc20,
python-virtualenv-1.10.1-1.

Thanks,

Hi,

Will, is this still a problem?

For these, we need to figure out if these are test problems or miscompiles.

Hi,

I've just moved the bots to a different box, and cleaned up a bunch (~
20G worth) of core.* files, so the disk space issue should be cleared
up, at least for the moment.

Not sure if the F20/LNT issue will magically clear up on this new host,
or not. If it' doesn't, i'll need to dig in.

Once the current builds finish, i'll have a better feel for whats
broken..

Failing Tests (4):
    Clang :: CodeGenCXX/debug-info-same-line.cpp

    Clang :: Modules/cxx-irgen.cpp
    Clang :: OpenMP/parallel_codegen.cpp

IIRC the fail for those two is due to a signext attribute showing up for
ppc*. I'll see if I can verify that and get something pushed soonish.
