Marge Bot pushed to branch wip/marge_bot_batch_merge_job at Glasgow Haskell Compiler / GHC Commits: 17839248 by Teo Camarasu at 2026-02-24T08:36:03-05:00 ghc-internal: avoid depending on GHC.Internal.Control.Monad.Fix This module contains the definition of MonadFix, since we want an instance for IO, that instance requires a lot of machinery and we want to avoid an orphan instance, this will naturally be quite high up in the dependency graph. So we want to avoid other modules depending on it as far as possible. On Windows, the IO manager depends on the RTSFlags type, which transtively depends on MonadFix. We refactor things to avoid this dependency, which would have caused a regression. Resolves #26875 Metric Decrease: T12227 - - - - - fa88d09a by Wolfgang Jeltsch at 2026-02-24T08:36:47-05:00 Refine the imports of `System.IO.OS` Commit 68bd08055594b8cbf6148a72d108786deb6c12a1 replaced the `GHC.Internal.Data.Bool` import by a `GHC.Internal.Base` import. However, while the `GHC.Internal.Data.Bool` import was conditional and partial, the `GHC.Internal.Base` import is unconditional and total. As a result, the import list is not tuned to import only the necessary bits anymore, and furthermore GHC emits a lot of warnings about redundant imports. This commit makes the `GHC.Internal.Base` import conditional and partial in the same way that the `GHC.Internal.Data.Bool` import was. - - - - - c951fef1 by Cheng Shao at 2026-02-25T20:58:28+00:00 wasm: add /assets endpoint to serve user-specified assets This patch adds an `/assets` endpoint to the wasm dyld http server, so that users can also fetch assets from the same host with sensible default MIME types, without needing a separate http server for assets that also introduces CORS headaches: - A `-fghci-browser-assets-dir` driver flag is added to specify the assets root directory (defaults to `$PWD`) - The dyld http server fetches `mime-db` on demand and uses it as source of truth for mime types.

I've refactored the code to simplify the generation of out-of-line Cmm code for the primop composed of some inline code + some call to an external Cmm function. - - - - - 32 changed files: - compiler/GHC/Builtin/Names.hs - compiler/GHC/Driver/Config/Interpreter.hs - compiler/GHC/Driver/DynFlags.hs - compiler/GHC/Driver/Session.hs - compiler/GHC/Runtime/Interpreter/Init.hs - compiler/GHC/Runtime/Interpreter/Types.hs - compiler/GHC/Runtime/Interpreter/Wasm.hs - compiler/GHC/StgToCmm/Prim.hs - docs/users_guide/wasm.rst - libraries/base/src/Control/Arrow.hs - libraries/base/src/System/IO.hs - libraries/ghc-internal/src/GHC/Internal/Control/Arrow.hs - libraries/ghc-internal/src/GHC/Internal/Control/Monad/Fix.hs - libraries/ghc-internal/src/GHC/Internal/Control/Monad/ST/Lazy/Imp.hs - libraries/ghc-internal/src/GHC/Internal/Data/Functor/Identity.hs - libraries/ghc-internal/src/GHC/Internal/Event/Windows/ManagedThreadPool.hs - libraries/ghc-internal/src/GHC/Internal/RTS/Flags/Test.hsc - libraries/ghc-internal/src/GHC/Internal/System/IO.hs - libraries/ghc-internal/src/GHC/Internal/System/IO/OS.hs - libraries/ghc-internal/src/GHC/Internal/TH/Monad.hs - + testsuite/tests/codeGen/should_fail/T26958.hs - testsuite/tests/codeGen/should_fail/all.T - testsuite/tests/ghci/scripts/ListTuplePunsPpr.stdout - testsuite/tests/ghci/scripts/T10963.stderr - testsuite/tests/ghci/scripts/T4175.stdout - 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/mdo/should_fail/mdofail006.stderr - utils/jsffi/dyld.mjs The diff was not included because it is too large.
