--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
struct SomeClass {
unsigned cfg1 : 1;
unsigned cfg2 : 1;
unsigned cfg3 : 1;
bool check() const noexcept { return cfg1 || cfg2 || cfg3; }
};
bool check(const SomeClass& rt) {
return rt.check();
}
works, but .original already exposed BIT_FIELD_REF <...> & CST for the
tests, but doesn't combine anything. That's premature and we should see
to get rid of it next stage1 as well (and make the ifcombine logic work
for the bool case which we refrain from touching in fold).
