Yes. We can already do that for TSan and MSan - sanitize_memory and
sanitize_thread
attrs are not added to functions by Clang if the functions are blacklisted.
There's still some
stuff to do in ASan w.r.t. global variables.
BTW, are we still inter...

[LLVMdev] Unifying TSan blacklist and no_sanitize_thread
Hi,
I consider reducing the usage of blacklist in sanitizer instrumentation
passes and doing the necessary work in frontend (Clang) instead.
Some of it is already implemented: e.g. Clang will attach an attribute
"sanitize_address" to function definition only if this function is not
blacklisted. In this case we won't instrument the memory accesses in this
function in ASan
