See http://lists.llvm.org/pipermail/llvm-dev/2017-June/113975.html for a related previous discussion. Many tools install signal handlers to print stack traces and optionally symbolize the addresses with an external program 'llvm-symbolizer' (when searching for 'llvm-symbolizer', the directory containg the executable is preferred over PATH). 'llvm-symbolizer' can be slow if the executable is large and/or if llvm-symbolizer' itself is under-optimized. For example, my 'llvm-lto2' from a -DCMAKE_BUILD_TYPE=Debug build is 443MiB. The 'llvm-symbolizer' from the same build takes ~2s to symbolize it. (An optimized 'llvm-symbolizer' takes 0.34s). A crashed clang may take more than 5s to symbolize a stack trace. If a test file has several `not --crash` RUN lines. It can be very slow in a Debug build. This patch makes `not --crash` set an environment variable to suppress symbolization. This is similar to D33804 which uses a command line option. I pick 'symbolization' instead of 'symbolication' because the former is used much more commonly and its stem matches 'llvm-symbolizer'. Also set LLVM_DISABLE_CRASH_REPORT=1, which is currently only applicable on `__APPLE__`. Reviewed By: dblaikie, aganea Differential Revision: https://reviews.llvm.org/D86170 |
