Add flag to configure `noalias` on `Box<T>` To aid making an informed decision about the aliasing rules of box, give users an option to remove `noalias` from box. 2022-07-18 16:17:27 +00:00			`// compile-flags: -O -Z box-noalias=no`

make noalias-box-off filecheck more precise The CHECK, -NOT, -SAME pattern ensures that the `CHECK-NOT: noalias` is limited to only one line, and won't match unrelated lines further down in the file. Explicit drop call added to preserve the `foo` argument name, since names of unused arguments are not preserved. 2023-05-20 23:41:28 +00:00			`// CHECK-NOT: noalias`
