Zubin pushed to branch wip/9.12.3-backports at Glasgow Haskell Compiler / GHC Commits: 91db1d51 by Zubin Duggal at 2025-09-16T08:52:56+00:00 QuickLook: do a shape test before unifying This commit ensures we do a shape test before unifying.

[Git][ghc/ghc][wip/az/ghc-cpp] 154 commits: Move ModuleGraph into UnitEnv
by Alan Zimmerman (＠alanz) 15 Sep '25

15 Sep '25

Alan Zimmerman pushed to branch wip/az/ghc-cpp at Glasgow Haskell Compiler / GHC Commits: 0fb37893 by Matthew Pickering at 2025-06-23T13:55:10-04:00 Move ModuleGraph into UnitEnv The ModuleGraph is a piece of information associated with the ExternalPackageState and HomeUnitGraph. Therefore we should store it inside the HomeUnitEnv. - - - - - 3bf6720e by soulomoon at 2025-06-23T13:55:52-04:00 Remove hptAllFamInstances usage during upsweep Fixes #26118 This change eliminates the use of hptAllFamInstances during the upsweep phase, as it could access non-below modules from the home package table. The following updates were made: * Updated checkFamInstConsistency to accept an explicit ModuleEnv FamInstEnv parameter and removed the call to hptAllFamInstances. * Adjusted hugInstancesBelow so we can construct ModuleEnv FamInstEnv from its result, * hptAllFamInstances and allFamInstances functions are removed. - - - - - 83ee7b78 by Ben Gamari at 2025-06-24T05:02:07-04:00 configure: Don't force value of OTOOL, etc. if not present Previously if `otool` and `install_name_tool` were not present they would be overridden by `fp_settings.m4`. This logic was introduced in 4ff93292243888545da452ea4d4c1987f2343591 without explanation. - - - - - 9329c9e1 by Ben Gamari at 2025-06-24T05:02:07-04:00 ghc-toolchain: Add support for otool, install_name_tool Fixes part of ghc#23675. - - - - - 25f5c998 by Ben Gamari at 2025-06-24T05:02:08-04:00 ghc-toolchain: Add support for llc, opt, llvm-as Fixes #23675. - - - - - 51d150dd by Rodrigo Mesquita at 2025-06-24T05:02:08-04:00 hadrian: Use settings-use-distro-mingw directly The type `ToolchainSetting` only made sense when we had more settings to fetch from the system config file. Even then "settings-use-distro-mingw" is arguably not a toolchain setting. With the fix for #23675, all toolchain tools were moved to the `ghc-toolchain` `Toolchain` format. Therefore, we can inline `settings-use-distro-mingw` accesses and delete `ToolchainSetting`. - - - - - dcf68a83 by Rodrigo Mesquita at 2025-06-24T05:02:08-04:00 configure: Check LlvmTarget exists for LlvmAsFlags If LlvmTarget was empty, LlvmAsFlags would be just "--target=". If it is empty now, simply keep LlvmAsFlags empty. ghc-toolchain already does this right. This fix makes the two configurations match up. - - - - - 580a3353 by Ben Gamari at 2025-06-24T05:02:51-04:00 rts/linker/LoadArchive: Use bool Improve type precision by using `bool` instead of `int` and `StgBool`. - - - - - 76d1041d by Ben Gamari at 2025-06-24T05:02:51-04:00 rts/linker/LoadArchive: Don't rely on file extensions for identification Previously archive members would be identified via their file extension, as described in #13103. We now instead use a more principled approach, relying on the magic number in the member's header. As well, we refactor treatment of archive format detection to improve code clarity and error handling.

We add a new utility function which allows us to find a `HomeUnitModule` instead of a `Module`. Further, we introduce the `GhciCommandError` type which can be used to abort the execution of a GHCi command. This error is caught and printed in a human readable fashion. - - - - - b3d97bb3 by fendor at 2025-06-25T17:06:25-04:00 Implement `-fno-load-initial-targets` flag We add the new flag `-fno-load-initial-targets` which doesn't load all `Target`s immediately but only computes the module graph for all `Target`s. The user can then decide to load modules from that module graph using the syntax: ghci> :reload <Mod> This will load everything in the module graph up to `Mod`. The user can return to the initial state by using the builtin target `none` to unload all modules. ghci> :reload none Is in principle identical to starting a new session with the `-fno-load-initial-targets` flag. The `-fno-load-initial-targets` flag allows for faster startup time of GHCi when a user has lots of `Target`s. We additionally extend the `:reload` command to accept multiple `ModuleName`s. For example: ghci> :reload <Mod1> <Mod2> Loads all modules up to the modules `Mod1` and `Mod2`. - - - - - 49f44e52 by Teo Camarasu at 2025-06-26T04:19:51-04:00 Expose ghc-internal unit id through the settings file This in combination with the unit id of the compiler library allows cabal to know of the two unit ids that should not be reinstalled (in specific circumstances) as: - when using plugins, we want to link against exactly the compiler unit id - when using TemplateHaskell we want to link against exactly the package that contains the TemplateHaskell interfaces, which is `ghc-internal` See: <https://github.com/haskell/cabal/issues/10087> Resolves #25282 - - - - - 499c4efe by Bryan Richter at 2025-06-26T04:20:33-04:00 CI: Fix and clean up capture of timings * Fixes the typo that caused 'cat ci-timings' to report "no such file or directory" * Gave ci_timings.txt a file extension so it may play better with other systems * Fixed the use of time_it so all times are recorded * Fixed time_it to print name along with timing - - - - - 86c90c9e by Bryan Richter at 2025-06-26T04:20:33-04:00 CI: Update collapsible section usage The syntax apparently changed at some point. - - - - - 04308ee4 by Bryan Richter at 2025-06-26T04:20:33-04:00 CI: Add more collapsible sections - - - - - 6ac906a1 by Alan Zimmerman at 2025-06-26T18:37:53+01:00 GHC-CPP: first rough proof of concept Processes #define FOO #ifdef FOO x = 1 #endif Into [ITcppIgnored [L loc ITcppDefine] ,ITcppIgnored [L loc ITcppIfdef] ,ITvarid "x" ,ITequal ,ITinteger (IL {il_text = SourceText "1", il_neg = False, il_value = 1}) ,ITcppIgnored [L loc ITcppEndif] ,ITeof] In time, ITcppIgnored will be pushed into a comment - - - - - fe321296 by Alan Zimmerman at 2025-06-26T18:37:53+01:00 Tidy up before re-visiting the continuation mechanic - - - - - e02bec42 by Alan Zimmerman at 2025-06-26T18:37:53+01:00 Switch preprocessor to continuation passing style Proof of concept, needs tidying up - - - - - 44112223 by Alan Zimmerman at 2025-06-26T18:37:53+01:00 Small cleanup - - - - - b94f4af1 by Alan Zimmerman at 2025-06-26T18:37:53+01:00 Get rid of some cruft - - - - - 175d73a2 by Alan Zimmerman at 2025-06-26T18:37:53+01:00 Starting to integrate.
