I can confirm that C (GCC and Clang) will generate this:
7e2f0: f3 0f 1e fa endbr64
7e2f4: 64 48 8b 04 25 f8 ff mov %fs:0xfffffffffffffff8,%rax
7e2fb: ff ff
7e2fd: c3 ret
7e2fe: 66 90 xchg %ax,%ax
But they did not inline the function that does that, even with `__attribute__((always_inline))` and link-time optimization. I need to investigate that.
Is this from a shared library (compiled with -fPIC and linked with -shared) though? That's where the big troubles start and I think C isn't better than C++ here
I am grateful that I only use one multi-call executable (built from a monorepo made partially because of your post, btw) because I think shared libraries in C might have the same sort of problems, just without constructors.
