This patch flips the default value for -gcolumn-info to be on by default. I discussed the rationale and provided compile/size data in: http://lists.cs.uiuc.edu/pipermail/llvmdev/2014-June/074290.html This also updates the documentation and some tests that relied on the lack of column information. Some tests had column information in the expected output, but it was wrong (the tsan tests). Others were using the driver to execute. llvm-svn: 212781
