Brandon Chinn pushed to branch wip/bchinn-argparse-filetype at Glasgow Haskell Compiler / GHC Commits: 4be32153 by Teo Camarasu at 2025-10-15T08:06:09-04:00 Add submodules for template-haskell-lift and template-haskell-quasiquoter These two new boot libraries expose stable subsets of the template-haskell interface. This is an implemenation of the GHC proposal https://github.com/ghc-proposals/ghc-proposals/pull/696 Work towards #25262 - - - - - 0c00c9c3 by Ben Gamari at 2025-10-15T08:06:51-04:00 rts: Eliminate uses of implicit constant arrays Folding of `const`-sized variable-length arrays to a constant-length array is a gnu extension which clang complains about. Closes #26502. - - - - - 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 - - - - - ba3e5bdd by Rodrigo Mesquita at 2025-10-18T16:57:18-04:00 Move code-gen aux symbols from ghc-internal to rts These symbols were all previously defined in ghc-internal and made the dependency structure awkward, where the rts may refer to some of these symbols and had to work around that circular dependency the way described in #26166. Moreover, the code generator will produce code that uses these symbols! Therefore, they should be available in the rts: PRINCIPLE: If the code generator may produce code which uses this symbol, then it should be defined in the rts rather than, say, ghc-internal. That said, the main motivation is towards fixing #26166. Towards #26166.

One source of such references in the RTS is the many symbols referenced in ghc-internal. To mitigate #26166, we make these references dynamic, as described in Note [RTS/ghc-internal interface].
