* Refactor LoggerSylvain Henry2021-02-131-0/+6
| | | | | | | | | | | | | | | | | | | | | Before this patch, the only way to override GHC's default logging behavior was to set `log_action`, `dump_action` and `trace_action` fields in DynFlags. This patch introduces a new Logger abstraction and stores it in HscEnv instead. This is part of #17957 (avoid storing state in DynFlags). DynFlags are duplicated and updated per-module (because of OPTIONS_GHC pragma), so we shouldn't store global state in them. This patch also fixes a race in parallel "--make" mode which updated the `generatedDumps` IORef concurrently. Bump haddock submodule The increase in MultilayerModules is tracked in #19293. Metric Increase: MultiLayerModules
* Use mutable update to defer out-of-scope errorsRichard Eisenberg2020-12-251-1/+7
| | | | | | | | | | | | | Previously, we let-bound an identifier to use to carry the erroring evidence for an out-of-scope variable. But this failed for levity-polymorphic out-of-scope variables, leading to a panic (#17812). The new plan is to use a mutable update to just write the erroring expression directly where it needs to go. Close #17812. Test case: typecheck/should_compile/T17812
