Subject: Emit fake borrows for all tests
X-Git-Url: https://git.lizzy.rs/?a=commitdiff_plain;h=b5643f1a490d6aa5f90fc45fd92ac34d6e8a05d8;p=rust.git

Emit fake borrows for all tests

I was incorrectly under the impression that this would only lead to
duplicates. See `mir-opt/match-arm-scope.rs` (upcomming commit) for a
case where we didn't emit a fake borrow of `items.1`.
