Automatic scan-build on the LLVM toolchain
After setting an automatic code coverage tool, I just plugged an automatic scan-build on the LLVM toolchain trunk:
- polly is currently not analyzed. I had to disable the build until the new version of cloog is available.
- compiler-rt is not analyzed because it does not respect the CC/CXX argument to use the clang built locally . Not sure it is a bug here.
This work is done through the Debian/LLVM jenkins instance.
The report is updated twice a day.
The scan-build/clang used to produce the report is the one published on http://llvm.org/apt/. That means that a new feature/fix done on scan-build will appear only about a day after on report. As a side effect, it tests automatically the packages distributed on llvm.org/apt/.
For a project of this size, the number of reported errors / warnings is pretty low. At time of writing, only 329 errors are reported and many of them are in generated code (AttrDump.inc and LLDBWrapPython.cpp for example) or in unit tests.
