--- Comment #11 from Antony Polukhin <antoshkka at gmail dot com> --- Seems perfect https://godbolt.org/g/GX3GQd The mov is not generated for any constructor and the following code: extern struct A a; struct A { int m, n; A(const A &v); }; A::A(const A &v) : m(v.m), n((a.m = 1, v.m)) {} Is not optimized to "A::A(int, const A &v) : m(v.m), n(v.m) { a.m = 1; }" (which is a mistake). Are there some tests to make sure that the `mov` won't appear again?
