Yuki Okushi f8539221d0 Rollup merge of #78524 - tmiasko:source-files-borrow, r=Aaron1011 ... Avoid BorrowMutError with RUSTC_LOG=debug ```console $ touch empty.rs $ env RUSTC_LOG=debug rustc +stage1 --crate-type=lib empty.rs ``` Fails with a `BorrowMutError` because source map files are already borrowed while `features_query` attempts to format a log message containing a span. Release the borrow before the query to avoid the issue.		2020-10-30 18:00:54 +09:00
