[Git][ghc/ghc][wip/fendor/t23703] 2 commits: Refactor distinct constructor tables map construction
Hannes Siebenhandl pushed to branch wip/fendor/t23703 at Glasgow Haskell Compiler / GHC Commits: 62f51fad by Finley McIlwaine at 2025-09-01T10:56:54+02:00 Refactor distinct constructor tables map construction Adds `GHC.Types.Unique.Map.alterUniqMap_L`, `GHC.Types.Unique.FM.alterUFM_L`, `GHC.Data.Word64Map.alterLookupWithKey` to support fusion of distinct constructor data insertion and lookup during the construction of the data con map in `GHC.Stg.Debug.numberDataCon`. - - - - - 561a1835 by Finley McIlwaine at 2025-09-01T10:57:59+02:00 Allow per constructor refinement of distinct-constructor-tables Introduce `-fno-distinct-constructor-tables`. A distinct constructor table configuration is built from the combination of flags given, in order. For example, to create distinct constructor tables for all constructors except for a specific few named `C1`,..., `CN`, pass `-fdistinct-contructor-tables` followed by `fno-distinct-constructor-tables=C1,...,CN`. To only generate distinct constuctor tables for a few specific constructors and no others, just pass `-fdistinct-constructor-tables=C1,...,CN`. 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.
