Therefore we need to persist the choice made at this time into the installation bindist as well so we look for the right tools, with the right prefixes at install time. In the future, we want to provide a bit more control about what kind of bindist we produce so the logic about what the host/target will have to be written by hadrian rather than persisted by the configure script. In particular with cross compilers we want to either build a normal stage 2 cross bindist or a stage 3 bindist, which creates a bindist which has a native compiler for the target platform.

Thus, these paramenters aren't required any longer. - - - - - fef35216 by Sven Tennie at 2026-04-08T04:37:30-04:00 ci: Define USER_CONF_CC_OPTS_STAGE2 for aarch64/mingw ghc-toolchain doesn't see $CONF_CC_OPTS_STAGE2 when the bindist gets configured. So, the hack to override the compiler gets lost. - - - - - 8dd6f453 by Cheng Shao at 2026-04-08T04:38:11-04:00 ghci: use ShortByteString for LookupSymbol/LookupSymbolInDLL/LookupClosure messages This patch refactors ghci to use `ShortByteString` for `LookupSymbol`/`LookupSymbolInDLL`/`LookupClosure` messages as the first part of #27147.

The `%m` syntax of linear types is now accepted in more places, to allow use by future extensions, though so far linear types is still the only consumer. This may break existing code where it * Uses -XLinearTypes. * Has code of the form `a %m -> b`, where `m` can't be inferred to be kind Multiplicity. The code can be fixed either by adding a kind annotation, or by setting `-XLinearTypes -XNoModifiers`.

Since we only build one version of each package, we don't need the hash to disambiguate anything, we can just remove it.

These functions are converted to using `upsert`: alter :: (Maybe a -> Maybe a) -> Key -> Map a -> Map a upsert :: (Maybe a -> a) -> Key -> Map a -> Map a `upsert` variants are also added to APIs of the various Word64Map wrapper types. The precedent for this `upsert` operation is in the containers library: see https://github.com/haskell/containers/pull/1145 Metrics: compile_time/bytes allocated ------------------------------------- geo. mean: -0.1% minimum: -0.5% maximum: +0.0% Resolves #27140. - - - - - da7e82f4 by Cheng Shao at 2026-04-08T20:54:49-04:00 testsuite: fix testsuite run for +ipe again This patch makes the +ipe flavour transformer pass the entire testsuite again by dropping stdout/stderr checks of certain tests that are sensitive to stack layout changes with `+ipe`.

Contributors add a file in changelog.d/ for each user-facing change. At release time, these are assembled into release notes for sphinx (in RST) format, using the tool. New hadrian `changelog` target to generate changelogs CI job to validate changelog entries for MRs unless skipped with ~"no-changelog" label Teach sphinx about ghc-mr: extlink to link to MRs Remove `ghc-package-list` from sphinx, and implement it in changelog-d instead (Fixes #26476).

This is silently wrong when cross-compiling from a 32-bit host to a 64-bit target: the host Int is 32 bits while the target Int is 64 bits. See Note [TargetInt] in GHC.Platform. Also used the opportunity to make DynTag = Word8.

The particular changes are as follows: * In `GHC.Unit.Module.Graph`, `ModuleGraph` is extended with a new field `mg_home_map`, exposed as `mgHomeModuleMap`. This is a data structure that caches the following: - The set of home units for which the graph has a complete module listing - For each module name, the set of home unit IDs that define it Operations that construct module graphs are updated such that this cache stays synchronized. * In `GHC.Unit.Finder`, `findImportedModule` is changed to pull `mgHomeModuleMap` from `hsc_mod_graph` and pass it to `findImportedModuleNoHsc`, which now does not search all home units that the current unit depends on but first searches those of them that the cache mentions as potential providers of the requested module and, if this fails, only those for which the module graph is incomplete. The practical effect is that for unqualified and this-package imports, the finder never blindly searches every home unit on which the current unit depends when the current module graph already states which units may provide the requested module. This is a performance optimization, especially for multi-home-unit builds. Resolves #27055.

[Git][ghc/ghc][master] Introduce TargetInt to represent target's Int (#15973)
by Marge Bot (＠marge-bot) 11 Apr '26

11 Apr '26

Marge Bot pushed to branch master at Glasgow Haskell Compiler / GHC Commits: 2df604e9 by Sylvain Henry at 2026-04-11T02:19:30-04:00 Introduce TargetInt to represent target's Int (#15973) GHC was using host 'Int' in several places to represent values that live in the target machine's 'Int' type. This is silently wrong when cross-compiling from a 32-bit host to a 64-bit target: the host Int is 32 bits while the target Int is 64 bits. See Note [TargetInt] in GHC.Platform. Also used the opportunity to make DynTag = Word8.

[Git][ghc/ghc][wip/marge_bot_batch_merge_job] 20 commits: Implement modifiers syntax.
by Marge Bot (＠marge-bot) 10 Apr '26

10 Apr '26

Marge Bot pushed to branch wip/marge_bot_batch_merge_job at Glasgow Haskell Compiler / GHC Commits: 4a122bb6 by Phil Hazelden at 2026-04-08T20:49:42-04:00 Implement modifiers syntax. The `%m` syntax of linear types is now accepted in more places, to allow use by future extensions, though so far linear types is still the only consumer. This may break existing code where it * Uses -XLinearTypes. * Has code of the form `a %m -> b`, where `m` can't be inferred to be kind Multiplicity. The code can be fixed either by adding a kind annotation, or by setting `-XLinearTypes -XNoModifiers`.

Since we only build one version of each package, we don't need the hash to disambiguate anything, we can just remove it.

Fixes #27106. - - - - - b7a084cc by Simon Jakobi at 2026-04-08T20:53:27-04:00 Documentation fixes for demand signature notation Fixes #27115. - - - - - 59391132 by Simon Jakobi at 2026-04-08T20:54:08-04:00 Use upsert for non-deleting map updates Some compiler functions were using `alter`, despite never removing any entries: they only update an existing entry or insert a new one. These functions are converted to using `upsert`: alter :: (Maybe a -> Maybe a) -> Key -> Map a -> Map a upsert :: (Maybe a -> a) -> Key -> Map a -> Map a `upsert` variants are also added to APIs of the various Word64Map wrapper types. The precedent for this `upsert` operation is in the containers library: see https://github.com/haskell/containers/pull/1145 Metrics: compile_time/bytes allocated ------------------------------------- geo. mean: -0.1% minimum: -0.5% maximum: +0.0% Resolves #27140. - - - - - da7e82f4 by Cheng Shao at 2026-04-08T20:54:49-04:00 testsuite: fix testsuite run for +ipe again This patch makes the +ipe flavour transformer pass the entire testsuite again by dropping stdout/stderr checks of certain tests that are sensitive to stack layout changes with `+ipe`.

Contributors add a file in changelog.d/ for each user-facing change. At release time, these are assembled into release notes for sphinx (in RST) format, using the tool. New hadrian `changelog` target to generate changelogs CI job to validate changelog entries for MRs unless skipped with ~"no-changelog" label Teach sphinx about ghc-mr: extlink to link to MRs Remove `ghc-package-list` from sphinx, and implement it in changelog-d instead (Fixes #26476).

This is silently wrong when cross-compiling from a 32-bit host to a 64-bit target: the host Int is 32 bits while the target Int is 64 bits. See Note [TargetInt] in GHC.Platform. Also used the opportunity to make DynTag = Word8.
