Marge Bot pushed to branch wip/marge_bot_batch_merge_job at Glasgow Haskell Compiler / GHC Commits: 52d00c05 by Simon Peyton Jones at 2026-01-07T10:24:21-05:00 Add missing InVar->OutVar lookup in SetLevels As #26681 showed, the SetLevels pass was failing to map an InVar to an OutVar. Very silly! I'm amazed it hasn't broken before now. I have improved the type singatures (to mention InVar and OutVar) so it's more obvious what needs to happen. - - - - - ab0a5594 by Cheng Shao at 2026-01-07T10:25:04-05:00 hadrian: drop deprecated pkgHashSplitObjs code path This patch drops deprecated `pkgHashSplitObjs` code path from hadrian, since GHC itself has removed split objs support many versions ago and this code path is unused. - - - - - bb3a2ba1 by Cheng Shao at 2026-01-07T10:25:44-05:00 hadrian: remove linting/assertion in quick-validate flavour The `quick-validate` flavour is meant for testing ghc and passing the testsuite locally with similar settings to `validate` but faster. This patch removes the linting/assertion overhead in `quick-validate` to improve developer experience. I also took the chance to simplify redundant logic of rts/library way definition in `validate` flavour. - - - - - 7971f5dd by Cheng Shao at 2026-01-07T10:26:26-05:00 deriveConstants: clean up unused constants This patch cleans up unused constants from `deriveConstants`, they are not used by C/Cmm code in the RTS, nor compiler-generated code.

It's a sane default when you care about debugging and reliable backtraces, and makes debugging/profiling with bpf easier. - - - - - 8a3900a3 by Aaron Allen at 2026-01-07T10:27:57-05:00 [26705] Include TyCl instances in data fam iface entry Ensures dependent modules are recompiled when the class instances for a data family instance change. resolves #26705 - - - - - a0b980af by Cheng Shao at 2026-01-07T10:28:38-05:00 hadrian: remove unused Hp2Ps/Hpc builders This patch removes the Hp2Ps/Hpc builders from hadrian, they are unused in the build system. Note that the hp2ps/hpc programs are still built and not affected. - - - - - 50a58757 by Cheng Shao at 2026-01-07T10:29:20-05:00 hadrian: only install js files to libdir for wasm/js targets There are certain js files required for wasm/js targets to work, and previously hadrian would install those js files to libdir unconditionally on other targets as well. This could be a minor annoyance for packagers especially when the unused js files contain shebangs that interfere with the packaging process. This patch makes hadrian only selectively install the right js files for the right targets.

This patch changes the driver to use `-O3` as LLVM optimization level when compiling with `-O2`, which is a better default when we're willing to trade compilation time for faster generated code. - - - - - 36 changed files: - compiler/GHC/Core/Opt/SetLevels.hs - compiler/GHC/Driver/Pipeline/Execute.hs - compiler/GHC/Driver/Session.hs - compiler/GHC/Iface/Recomp.hs - − docs/Makefile - − docs/storage-mgt/Makefile - − docs/users_guide/Makefile - − driver/Makefile - − driver/ghc/Makefile - − driver/ghci/Makefile - − driver/haddock/Makefile - − ghc/Makefile - hadrian/doc/flavours.md - hadrian/src/Base.hs - hadrian/src/Builder.hs - hadrian/src/Flavour.hs - hadrian/src/Hadrian/Haskell/Hash.hs - hadrian/src/Oracles/Setting.hs - hadrian/src/Rules/Register.hs - hadrian/src/Settings/Flavours/Validate.hs - − libraries/Makefile - − libraries/doc/Makefile - − linters/lint-codes/Makefile - − linters/lint-notes/Makefile - llvm-passes - − rts/Makefile - − rts/include/Makefile - + testsuite/tests/driver/recomp26705/M.hs - + testsuite/tests/driver/recomp26705/M2A.hs - + testsuite/tests/driver/recomp26705/M2B.hs - + testsuite/tests/driver/recomp26705/Makefile - + testsuite/tests/driver/recomp26705/all.T - + testsuite/tests/driver/recomp26705/recomp26705.stderr - + testsuite/tests/simplCore/should_compile/T26681.hs - testsuite/tests/simplCore/should_compile/all.T - utils/deriveConstants/Main.hs The diff was not included because it is too large.
