`ubsan_minimal` makes use of the `_sanitizer::atomic_load` function. This function uses the `DCHECK` macro which in debug builds will use the `_sanitizer::CheckFailed` function. This function is part of `sanitizer_common` but `ubsan_minimal` doesn't use this so the implementation is missing which leads to link failures on macOS when trying to link `libclang_rt.ubsan_minimal_osx_dynamic.dylib`. This is in contrast to the BFD linker on Linux which doesn't seem to care about the missing symbol. A basic implementation of `_sanitizer::CheckFailed` has been added to the `ubsan_minimal` debug build to avoid the link error. The implementation could definitely be improved but I don't know which functions can be used in this context so I decided to restrict myself to functions only being used in `ubsan_minimal` already. llvm-svn: 326032 |
