Simon Peyton Jones pushed to branch wip/T26331 at Glasgow Haskell Compiler / GHC Commits: 5b5d9d47 by Ben Gamari at 2025-08-25T14:29:35-04:00 Revert "STM: don't create a transaction in the rhs of catchRetry# (#26028)" This reverts commit 0a5836891ca29836a24c306d2a364c2e4b5377fd - - - - - 10f06163 by Cheng Shao at 2025-08-25T14:30:16-04:00 wasm: ensure setKeepCAFs() is called in ghci This patch is a critical bugfix for #26106, see comment and linked issue for details. - - - - - bedc1004 by Cheng Shao at 2025-08-26T09:31:18-04:00 compiler: use zero cost coerce in hoopl setElems/mapToList This patch is a follow-up of !14680 and changes setElems/mapToList in GHC/Cmm/Dataflow/Label to use coerce instead of mapping mkHooplLabel over the keys. - - - - - 13250d97 by Ryan Scott at 2025-08-26T09:31:59-04:00 Reject infix promoted data constructors without DataKinds In the rename, make sure to apply the same `DataKinds` checks for both `HsTyVar` (for prefix promoted data constructors) and `HsOpTy` (for infix promoted data constructors) alike. Fixes #26318. - - - - - 37655c46 by Teo Camarasu at 2025-08-26T15:24:51-04:00 tests: disable T22859 under LLVM This test was failing under the LLVM backend since the allocations differ from the NCG. Resolves #26282 - - - - - 2cbba9d6 by Teo Camarasu at 2025-08-26T15:25:33-04:00 base-exports: update version numbers As the version of the compiler has been bumped, a lot of the embedded version numbers will need to be updated if we ever run this test with `--test-accept` so let's just update them now, and keep future diffs clean. - - - - - f9f2ffcf by Alexandre Esteves at 2025-08-27T07:19:14-04:00 Import new name for 'utimbuf' on windows to fix #26337 Fixes an `-Wincompatible-pointer-types` instance that turns into an error on recent toolchains and surfaced as such on nixpkgs when doing linux->ucrt cross. This long-standing warning has been present at least since 9.4: ``` C:\GitLabRunner\builds\0\1709189\tmp\ghc16652_0\ghc_4.c:26:115: error: warning: incompatible pointer types passing 'struct utimbuf *' to parameter of type 'struct _utimbuf *' [-Wincompatible-pointer-types] | 26 | HsInt32 ghczuwrapperZC9ZCbaseZCSystemziPosixziInternalsZCzuutime(char* a1, struct utimbuf* a2) {return _utime(a1, a2);} | ^ HsInt32 ghczuwrapperZC9ZCbaseZCSystemziPosixziInternalsZCzuutime(char* a1, struct utimbuf* a2) {return _utime(a1, a2);} ^~ C:\GitLabRunner\builds\0\1709189\_build\stage0\lib\..\..\mingw\x86_64-w64-mingw32\include\sys\utime.h:109:72: error: note: passing argument to parameter '_Utimbuf' here | 109 | __CRT_INLINE int __cdecl _utime(const char *_Filename,struct _utimbuf *_Utimbuf) { | ^ __CRT_INLINE int __cdecl _utime(const char *_Filename,struct _utimbuf *_Utimbuf) { ``` - - - - - ae89f000 by Hassan Al-Awwadi at 2025-08-27T07:19:56-04:00 Adds the fucnction addDependentDirectory to Q, resolving issue #26148. This function adds a new directory to the list of things a module depends upon. That means that when the contents of the directory change, the recompilation checker will notice this and the module will be recompiled. Documentation has also been added for addDependentFunction and addDependentDirectory in the user guide. - - - - - be2fdbbf by Simon Peyton Jones at 2025-08-27T16:39:49+01:00 Fix deep subsumption again This commit fixed #26255: commit 56b32c5a2d5d7cad89a12f4d74dc940e086069d1 Author: sheaf <sam.derbyshire@gmail.com> Date: Mon Aug 11 15:50:47 2025 +0200 Improve deep subsumption This commit improves the DeepSubsumption sub-typing implementation in GHC.Tc.Utils.Unify.tc_sub_type_deep by being less eager to fall back to unification. But alas it still wasn't quite right for view patterns: #26133. This MR does a generalisation to fix it. A bit of a sledgehammer to crack a nut, but nice. * Add a field `ir_inst :: InferInstFlag` to `InferResult`, where ``` data InferInstFlag = IIF_Sigma | IIF_ShallowRho | IIF_DeepRho ``` * The flag says exactly how much `fillInferResult` should instantiate before filling the hole. * We can also use this to replace the previous very ad-hoc `tcInferSigma` that was used to implement GHCi's `:type` command. - - - - - 53 changed files: - compiler/GHC/Cmm/Dataflow/Label.hs - compiler/GHC/HsToCore/Usage.hs - compiler/GHC/Iface/Make.hs - compiler/GHC/Iface/Recomp.hs - compiler/GHC/Iface/Recomp/Types.hs - compiler/GHC/Rename/HsType.hs - compiler/GHC/Tc/Gen/App.hs - compiler/GHC/Tc/Gen/Bind.hs - compiler/GHC/Tc/Gen/Expr.hs - compiler/GHC/Tc/Gen/Expr.hs-boot - compiler/GHC/Tc/Gen/Head.hs - compiler/GHC/Tc/Gen/HsType.hs - compiler/GHC/Tc/Gen/Match.hs - compiler/GHC/Tc/Gen/Pat.hs - compiler/GHC/Tc/Gen/Splice.hs - compiler/GHC/Tc/Module.hs - compiler/GHC/Tc/Types.hs - compiler/GHC/Tc/Utils/Monad.hs - compiler/GHC/Tc/Utils/TcMType.hs - compiler/GHC/Tc/Utils/TcType.hs - compiler/GHC/Tc/Utils/Unify.hs - compiler/GHC/Unit/Finder.hs - compiler/GHC/Unit/Finder/Types.hs - compiler/GHC/Unit/Module/Deps.hs - docs/users_guide/9.16.1-notes.rst - docs/users_guide/separate_compilation.rst - libraries/ghc-internal/src/GHC/Internal/System/Posix/Internals.hs - libraries/ghc-internal/src/GHC/Internal/TH/Syntax.hs - libraries/ghci/GHCi/Message.hs - libraries/ghci/GHCi/TH.hs - libraries/template-haskell/Language/Haskell/TH/Syntax.hs - rts/PrimOps.cmm - rts/RaiseAsync.c - rts/STM.c - testsuite/.gitignore - testsuite/tests/interface-stability/base-exports.stdout - testsuite/tests/interface-stability/base-exports.stdout-javascript-unknown-ghcjs - testsuite/tests/interface-stability/base-exports.stdout-mingw32 - testsuite/tests/interface-stability/base-exports.stdout-ws-32 - testsuite/tests/interface-stability/template-haskell-exports.stdout - − testsuite/tests/lib/stm/T26028.hs - − testsuite/tests/lib/stm/T26028.stdout - − testsuite/tests/lib/stm/all.T - testsuite/tests/rts/all.T - testsuite/tests/th/Makefile - + testsuite/tests/th/TH_Depends_Dir.hs - + testsuite/tests/th/TH_Depends_Dir.stdout - + testsuite/tests/th/TH_Depends_Dir_External.hs - testsuite/tests/th/all.T - + testsuite/tests/typecheck/should_fail/T26318.hs - + testsuite/tests/typecheck/should_fail/T26318.stderr - testsuite/tests/typecheck/should_fail/all.T - utils/jsffi/dyld.mjs The diff was not included because it is too large.
