[Sanitizer] Change driver behavior when linking with -fsanitize=thread and -fsanitize=memory. TSan/MSan also provide their versions of new/delete and should use the same strategy as ASan. Share the code that sets linker flags for all sanitizers. llvm-svn: 176178

If a .syms file is available alongside a sanitizer runtime, pass it to the linker via --dynamic-list instead of using --export-dynamic. This reduces the size of the dynamic symbol table, and thus of the binary (in some cases by up to ~30%). llvm-svn: 177783

Add -lrt to sanitizer link arguments. Sanitizer runtime intercepts functions from librt. Not doing this will fail if the librt dependency is not present at program startup (ex. comes from a dlopen()ed library). llvm-svn: 182645

Split ubsan runtime into three pieces (clang part): * libclang_rt-san-* is sanitizer_common, and is linked in only if no other sanitizer runtime is present. * libclang_rt-ubsan-* is the piece of the runtime which doesn't depend on a C++ ABI library, and is always linked in. * libclang_rt-ubsan_cxx-* is the piece of the runtime which depends on a C++ ABI library, and is only linked in when linking a C++ binary. This change also switches us to using -whole-archive for the ubsan runtime (which is made possible by the above split), and switches us to only linking the sanitizer runtime into the main binary and not into DSOs (which is made possible by using -whole-archive). The motivation for this is to only link a single copy of sanitizer_common into any binary. This is becoming important now because we want to share more state between multiple sanitizers in the same process (for instance, we want a single shared output mutex). The Darwin ubsan runtime is unchanged; because we use a DSO there, we don't need this complexity. llvm-svn: 177605

Update link strategy for sanitizer runtime libraries on Linux: 1. Always put static sanitizer runtimes to the front of the linker invocation line. This was already done for all sanitizers except UBSan: in case user provides static libstdc++ we need to make sure that new/delete operator definitions are picked from sanitizer runtimes instead of libstdc++. We have to put UBSan runtime first for similar reasons: it depends on some libstdc++ parts (e.g. __dynamic_cast function), and has to go first in link line to ensure these functions will be picked up from libstdc++. 2. Put sanitizer libraries system dependencies (-ldl, -lpthread etc.) right after sanitizer runtimes. This will ensure these libraries participate in the link even if user provided -Wl,-as-needed flag. This should fix PR15823. 3. In case we link in several sanitizer runtimes (e.g. "ubsan", "ubsan_cxx" and "san"), add system dependencies (-ldl, -lpthread, ...) only once. llvm-svn: 215940

Add -link-cxx-sanitizer driver flag. Summary: This flag can be used to force linking of CXX-specific parts of sanitizer runtimes into the final executable. It gives more precise control than --driver-mode=g++ and comes handy when user links several object files with sanitized C++ code into an executable, but wants to provide libstdc++ himself, instead of relying on Clang dirver's behavior.
