Marge Bot pushed to branch wip/marge_bot_batch_merge_job at Glasgow Haskell Compiler / GHC Commits: bf902a1d by Fendor at 2025-10-15T16:00:59-04:00 Refactor distinct constructor tables map construction Adds `GHC.Types.Unique.FM.alterUFM_L`, `GHC.Types.Unique.DFM.alterUDFM_L` `GHC.Data.Word64Map.alterLookup` to support fusion of distinct constructor data insertion and lookup during the construction of the `DataCon` map in `GHC.Stg.Debug.numberDataCon`.

A distinct constructor table configuration is built from the combination of flags given, in order. For example, to only generate distinct constructor tables for a few specific constructors and no others, just pass `-fdistinct-constructor-tables-only=C1,...,CN`. This flag can be supplied multiple times to extend the set of constructors to generate a distinct info table for. You can disable generation of distinct constructor tables for all configurations by passing `-fno-distinct-constructor-tables`. The various configurations of these flags is included in the `DynFlags` fingerprints, which should result in the expected recompilation logic. Adds a test that checks for distinct tables for various given or omitted constructors. Updates CountDepsAst and CountDepsParser tests to account for new dependencies.

This accommodates the fact that pattern synonym declarations without a type signature can contain unfilled metavariables, e.g. if the RHS of the pattern synonym involves view-patterns whose type mentions promoted (level 0) metavariables. Just like we do for ordinary function bindings, we should allow these metavariables to be settled later, instead of eagerly performing a final zonk-to-type. Now, the final zonking-to-type for pattern synonyms is performed in GHC.Tc.Module.zonkTcGblEnv. Fixes #26465 - - - - - def2832f by Matthew Pickering at 2025-10-17T06:50:18-04:00 driver: Properly handle errors during LinkNode steps Previously we were not properly catching errors during the LinkNode step (see T9930fail test). This is fixed by wrapping the `LinkNode` action in `wrapAction`, the same handler which is used for module compilation.
