Track drop points in generator_interior This change adds the basic infrastructure for tracking drop ranges in generator interior analysis, which allows us to exclude dropped types from the generator type. Not yet complete, but many of the async/await and generator tests pass. The main missing piece is tracking branching control flow (e.g. around an `if` expression). The patch does include support, however, for multiple yields in th e same block. Issue #57478 2021-10-20 18:42:53 -05:00			`// check-pass`
Enable drop-tracking tests behind -Zdrop-tracking These were still disabled from the soft revert of drop tracking, which meant we were not catching regressions that were introduced while trying to fix drop tracking. 2022-02-28 14:55:50 -06:00			`// compile-flags: -Zdrop-tracking`
Disable drop range tracking in generators Generator drop tracking caused an ICE for generators involving the Never type (Issue #93161). Since this breaks miri, we temporarily disable drop tracking so miri is unblocked while we properly fix the issue. 2022-01-21 11:36:24 -06:00
