[LLVMdev] Deadlock in llvm-lit on windows 7
...> procData = [None] * len(procs)
> procData[-1] = procs[-1].communicate()
I am invoking python directly on windows to run the unit tests.
C:\Python27\python.exe C:\build\llvm\Release\bin\llvm-lit.py -v -j 12
--param build_mode=Release --param build_config=Win32
llvm_site_config=C:\llvm_on_win\nightly\build\llvm\tools\polly\test\lit.site
.cfg test
Note: If I invoke with "-j 1" , the unit tests finish but took a lot of
time. There is no deadlock. I am using python version 2.7.6.
At this moment, I believe the issue is caused by stdout filling the OS
buffer there by blocking...
