...sans-paille/fortify-test-suite And indeed, clang doesn't pass it, mostly because it turns call to __builtin__(.*)_chk into calls to __builtin__\1. We need to support the runtime behavior of the following builtins: - __builtin___memcpy_chk - __builtin___memmove_chk - __builtin___mempcpy_chk - __builtin___memset_chk - __builtin___snprintf_chk - __builtin___sprintf_chk - __builtin___stpcpy_chk - __builtin___strcat_chk - __builtin___strcpy_chk - __builtin___strncat_chk - __builtin___strncpy_chk - __builtin___vsnprintf_chk - __builtin___vsprintf_chk And I'd like to implement them at clang level, leveraging t...
