There are generally three such parts: - address space memory mappings - setjmp mapping of stack pointer - setjmp/longjmp assembly code I noted that not all ATF TSan tests pass for GCC amd64. I suspect that the runtime is still too old (even older than Clang-7 2 years ago, when we added the ATF tests). Another difference is that LLVM by default links the runtime statically and GCC dynamically. There is a crash with dl_iterate_phdr(3). This is possibly related to the crash with -pg. GCC requires to deliver .spec files for static linking of sanitizers. We need to generate libsanitizer.spec and install it to /usr/lib/. I will have a look into it. GCC9 also wants to install libasan_preinit.o, liblsan_preinit.o, libtsan_preinit.o. I'm going to prepare appropriate build rules for them.
