This looks reasonable to me, but I'm not so familiar with the MIR design choices, so it'd be good for someone to double-check. r? @oli-obk |

lgtm. r=me after a rebase sorry about taking so long |
Cast type may be a subtype of the destination type. There is a later assertion that they have the same layout.
Fixes an ICE for the following code:
fn foo(_ : &()) {}
static X: fn(&'static ()) = foo;
This avoids some unnecessary moves

…p, r=oli-obk MIR generation cleanup * Handle the case where the body of a constant is a subtype of the type of the constant (see `mir_static_subtype.rs`). * Move the evaluation of `ExprKind::Use` into `into.rs`, saving an unnecessary copy.
