[RFC] Tooling for parsing and symbolication of Sanitizer reports
...thoughts on this RFC on the patch would be appreciated. # Issues with the existing solutions * An official parser for sanitizer reports does not exist. Currently we just tell our users to implement their own (e.g. [1]). This creates an unnecessary duplication of effort. * The existing symbolizer (asan_symbolize.py) only works with ASan reports and doesn’t support other sanitizers like TSan. * The architecture of the existing symbolizer makes it cumbersome to support inline frames. * The architecture of the existing symbolizer is sequential which prevents performing batched symbolication of stack frames....

For me, UBsan fails with clang 3.2 and passes with clang 3.3. Using a fixed version allows you to build all clang/llvm/compiler-rt with one compiler. It simplifies the build process quite a bit. Also better for isolating regressions in compiler-rt, especially if you use git-bisect. Greg On May 29, 2013, at 12:30 AM, Alexey Samsonov <samsonov at google.com> wrote: > UBsan tests work
