The `-fvia-C` part is now a deprecated no-op because GHC can't fall back to the C backend on a non-unregisterised build, and `-optc-msse3` might actually cause the test to fail on non x86/x64 platforms, e.g. recent builds of wasi-sdk would report `wasm32-wasi-clang: error: unsupported option '-msse3' for target 'wasm32-unknown-wasi'`. So this patch cleans up this historical cruft. `-fvia-C` is removed, and `-optc-msse3` is only passed when cpuid contains `pni` (which indicates support of SSE3). - - - - - 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.

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.
