It looks like 'make check-acceptance' creates directories in build/clang/tests/results which are huge and which it never cleans up. For example one of my build directories (configured just for arm targets) has over 350 'job-[timestamp]' directories, many of which are 2.5GB or more in size.
I assume most of this is artefacts (disk images etc) needed to rerun the tests. That's useful to keep around so you can manually run a test. However, we should be sharing this between runs, not creating a fresh copy for every time check-acceptance is run, surely ? I just freed 72 GB (!) of disk on my local box just by doing rm -rf build/arm-clang/tests/results/ ... thanks -- PMM
