Matthias Krüger 3b276cbe04 Rollup merge of #93603 - connorff:compute-polonius-liveness-facts-flag, r=ecstatic-morse ... Populate liveness facts when calling `get_body_with_borrowck_facts` without `-Z polonius` For a new feature of [Flowistry](https://github.com/willcrichton/flowistry), a static-analysis tool, we need to obtain a `mir::Body`'s liveness facts using `get_body_with_borrowck_facts` (added in #86977). We'd like to do this without passing `-Z polonius` as a compiler arg to avoid borrow checking the entire crate. Support for doing this was added in #88983, but the Polonius input facts used for liveness analysis are empty. This happens because the liveness input facts are populated in `liveness::generate` depending only on the value of `AllFacts::enabled` (which is toggled via compiler args). This PR propagates the [`use_polonius`](8b09ba6a5d/compiler/rustc_borrowck/src/nll.rs (L168)) flag to `liveness::generate` to support populating liveness facts without requiring the `-Z polonius` flag. This fix is somewhat patchy - if it'd be better to add more widely-accessible state (like `AllFacts::enabled`) I'd be open to ideas!		2022-02-26 00:49:20 +01:00
