Cheng Shao pushed to branch wip/deepseq-primop at Glasgow Haskell Compiler / GHC Commits: c72ddabf by Cheng Shao at 2025-12-23T16:13:23-05:00 hadrian: fix bootstrapping with ghc-9.14 This patch fixes bootstrapping GHC with ghc-9.14, tested locally with ghc-9.14.1 release as bootstrapping GHC. - - - - - 0fd6d8e4 by Cheng Shao at 2025-12-23T16:14:05-05:00 hadrian: pass -keep-tmp-files to test ghc when --keep-test-files is enabled This patch makes hadrian pass `-keep-tmp-files` to test ghc when `--keep-test-files` is enabled, so you can check the ghc intermediate files when debugging certain test failures. Closes #26688. - - - - - 81d10134 by Cheng Shao at 2025-12-24T06:11:52-05:00 configure: remove dead code in configure scripts This patch removes dead code in our configure scripts, including: - Variables and auto-detected programs that are not used - autoconf functions that are not used, or export a variable that's not used - `AC_CHECK_HEADERS` invocations that don't have actual corresponding `HAVE_XXX_H` usage - Other dead code (e.g. stray `AC_DEFUN()`) Co-authored-by: Codex - - - - - fb1381c3 by Wolfgang Jeltsch at 2025-12-24T06:12:34-05:00 Remove unused known keys and names for list operations This removes the known-key and corresponding name variables for `concat`, `filter`, `zip`, and `(++)`, as they are apparently nowhere used in GHC’s source code. - - - - - 7b9c20f4 by Recursion Ninja at 2025-12-24T10:35:36-05:00 Decoupling Language.Haskell.Syntax.Binds from GHC.Types.Basic by transferring InlinePragma types between the modules. * Moved InlinePragma data-types to Language.Haskell.Syntax.Binds.InlinePragma * Partitioned of Arity type synonyms to GHC.Types.Arity * InlinePragma is now extensible via Trees That Grow * Activation is now extensible via Trees That Grow * Maybe Arity change to more descriptive InlineSaturation data-type * InlineSaturation information removed from InlinePragma during GHS parsing pass * Cleaned up the exposed module interfaces of the new modules - - - - - a3afae0c by Simon Peyton Jones at 2025-12-25T15:26:36-05:00 Check for rubbish literals in Lint Addresses #26607.

Some numeric bugs only surface with optimization, omitting this can hide these bugs and even make them slip into release!
