Rodrigo Mesquita pushed to branch wip/T23675 at Glasgow Haskell Compiler / GHC Commits: 51837035 by Rodrigo Mesquita at 2025-06-17T11:26:31+01:00 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`. - - - - - 3 changed files: - hadrian/src/Builder.hs - hadrian/src/Oracles/Setting.hs - hadrian/src/Rules/Generate.hs Changes: ===================================== hadrian/src/Builder.hs ===================================== @@ -34,7 +34,6 @@ import Base import Context import Oracles.Flag import Oracles.Setting (setting, Setting(..)) -import Oracles.Setting (settingsFileSetting, ToolchainSetting(..)) import Packages import GHC.IO.Encoding (getFileSystemEncoding) @@ -240,7 +239,7 @@ instance H.Builder Builder where Ghc _ st -> do root <- buildRoot unlitPath <- builderPath Unlit - distro_mingw <- settingsFileSetting ToolchainSetting_DistroMinGW + distro_mingw <- lookupSystemConfig "settings-use-distro-mingw" libffi_adjustors <- useLibffiForAdjustors use_system_ffi <- flag UseSystemFfi ===================================== hadrian/src/Oracles/Setting.hs ===================================== @@ -75,19 +75,6 @@ data Setting = CursesIncludeDir | BourneShell | EmsdkVersion --- TODO compute solely in Hadrian, removing these variables' definitions --- from aclocal.m4 whenever they can be calculated from other variables --- already fed into Hadrian. - --- | All 'ToolchainSetting's are computed by the ghc-toolchain utility for configuring toolchains. --- This used to be defined by 'FP_SETTINGS' in aclocal.m4. --- --- TODO: We should be able to drop this completely, after moving all the toolchain settings to ghc-toolchain --- Move to ghc-toolchain and to the Target files generated by configure and ghc-toolchain --- * First we will get rid of DistroMinGW when we fix the windows build -data ToolchainSetting - = ToolchainSetting_DistroMinGW - -- | Look up the value of a 'Setting' in @cfg/system.config@, tracking the -- result. setting :: Setting -> Action String @@ -128,14 +115,6 @@ setting key = lookupSystemConfig $ case key of BourneShell -> "bourne-shell" EmsdkVersion -> "emsdk-version" --- | Look up the value of a 'SettingList' in @cfg/system.config@, tracking the --- result. --- See Note [tooldir: How GHC finds mingw on Windows] --- ROMES:TODO: This should be queryTargetTargetConfig -settingsFileSetting :: ToolchainSetting -> Action String -settingsFileSetting key = lookupSystemConfig $ case key of - ToolchainSetting_DistroMinGW -> "settings-use-distro-mingw" -- ROMES:TODO: This option doesn't seem to be in ghc-toolchain yet.
