ygao added a comment. In llvm/utils/lit/lit/TestRunner.py line#202 inside function executeShCmd(), the test is spawned by subprocess.Popen(command, ..., stdout = subprocess.PIPE, stderr = subprocess.PIPE, ...) And the test passes. I can verify with a small python script doing just a subprocess.Popen.
If the test is spawned with stdout = None instead, the test will crash as expected. I could not find a way to trick TestRunner into leaving stdout as None. Is there supposed to be a command-line option to lit? Or maybe a special redirection mark on the RUN line? Maybe a lit expert can help me here. http://reviews.llvm.org/D15705 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
