When building with Clang, I am getting many warnings from the selftests/rseq tree. Here's one such example from rseq tree: | param_test.c🔢10: error: address argument to atomic operation must be a pointer to _Atomic type ('intptr_t *' (aka 'long *') invalid) | 1234 | while (!atomic_load(&args->percpu_list_ptr)) {} | | ^ ~~~~~~~~~~~~~~~~~~~~~~ | /usr/local/google/home/justinstitt/repos/tc-build/build/llvm/final/lib/clang/18/include/stdatomic.h:140:29: note: expanded from macro 'atomic_load' | 140 | #define atomic_load(object) __c11_atomic_load(object, __ATOMIC_SEQ_CST) | | ^ ~~~~~~ Use compiler builtins `__atomic_load_n()` and `__atomic_store_n()` with accompanying __ATOMIC_ACQUIRE and __ATOMIC_RELEASE, respectively. This will fix the warnings because the compiler builtins do not expect their arguments to have _Atomic type. This should also make TSAN happier.
