I followed the LNT quickstart guide ( http://llvm.org/docs/lnt/quickstart.html) on my debian machine, and it seems to have a problem running. When I consult test.log, every single test has a section like this # Pretend that the reference output was produced instantaneously.> cp /home/jeremy/hardware/llvm/test-suite/instant.txt > Output/sse.expandfft.out-nat.time > /home/jeremy/hardware/llvm/test-suite/DiffOutput.sh > "/home/jeremy/hardware/llvm/mysandbox/test-2014-06-24_20-20-59/tools/fpcmp > -r 0.016" simple sse.expandfft > rm -f Output/sse.expandfft.exe-simple > cp Output/sse.expandfft.diff-simple Output/sse.expandfft.exe-simple > /bin/sh: 7: test: 0: unexpected operator > if test -f Output/sse.expandfft.extra-results.txt; then \ > /home/jeremy/hardware/llvm/test-suite/ParseMultipleResults > /home/jeremy/hardware/llvm/mysandbox/test-2014-06-24_20-20-59/SingleSource/UnitTests/Vector/SSE/sse.expandfft > Output/sse.expandfft.extra-results.txt >> > Output/sse.expandfft.simple.exec.report.txt; \ > fi > cat Output/sse.expandfft.simple.compile.report.txt > Output/sse.expandfft.simple.exec.report.txt >> > Output/sse.expandfft.simple.report.txt >Notice the line "/bin/sh: 7: test: 0: unexpected operator". Although I don't understand how the LNT infrastructure works exactly, I'm pretty sure that this is an error due to the difference between bash and dash, the default /bin/sh on debian. When I tried running one of the make commands that LNT runs with the additional option SHELL=/bin/bash I got similar output, but without the error. I'm not sure what bash specific features are being used. I'd want LNT to use bash as a workaround, but I'm not sure how to change which shell LNT uses (export SHELL=/bin/bash doesn't work). Any help with this would be appreciated. Jeremy -------------- next part -------------- An HTML attachment was scrubbed...

The attached patch didn't fix it, but when I also changed another == to = a few lines further down it seemed to work.
