Possibly, at least when we know it doesn't expand to a libatomic call? OTOH
even then a function just wrapping such call should probably be inlined,
so the question is whether the problem that
_3 = &MEM[(const struct __atomic_base *)this_1(D)]._M_i;
freq:1.00 size: 0 time: 0
_4 = __atomic_load_1 (_3, 0);
freq:1.00 size: 4 time: 13
_5 = (char) _4;
freq:1.00 size: 0 time: 0
return _5;
freq:1.00 size: 1 time: 2
is estimated as too big compared to the call calling the function
(OTOH a1.test () has no arguments while __atomic_load_1 has two).
