Marge Bot pushed to branch wip/marge_bot_batch_merge_job at Glasgow Haskell Compiler / GHC Commits: e36a5fcb by Matthew Pickering at 2025-12-05T16:25:57-05:00 Add support for building bytecode libraries A bytecode library is a collection of bytecode files (.gbc) and a library which combines together additional object files. A bytecode library is created by invoking GHC with the `-bytecodelib` flag. A library can be created from in-memory `ModuleByteCode` linkables or by passing `.gbc` files as arguments on the command line.

If a user enables `-fprefer-byte-code`, then if a package provides a bytecode library, that will be loaded and used to satisfy the dependency. The main change is to separate the relevant parts of the `LoaderState` into external and home package byte code. Bytecode is loaded into either the home package or external part (similar to HPT/EPS split), HPT bytecode can be unloaded. External bytecode is never unloaded. The unload function has also only been called with an empty list of "stable linkables" for a long time. It has been modified to directly implement a complete unloading of the home package bytecode linkables. At the moment, the bytecode libraries are found in the "library-dirs" field from the package description. In the future when `Cabal` implements support for "bytecode-library-dirs" field, we can read the bytecode libraries from there. No changes to the Cabal submodule are necessary at the moment. Four new tests are added in testsuite/tests/cabal, which generate fake package descriptions and test loading the libraries into GHCi.

This is not the case, e.g. in some situations involving exact names (see the test-case). The fix is to first check whether the node is present in the graph at all, instead of panicking, just to report that there is no path.

In some cases we construct an argument list too long for GHC to handle directly on windows. This happens when we generate the dependency file because the command line will contain references to a large number of .hs files. To avoid this we now invoke GHC using a response file when generating dependencies to sidestep length limitations. Note that we only pass the actual file names in the dependency file. Why? Because this side-steps #26560 - - - - - e7e53af4 by Marc Scholten at 2025-12-05T17:01:13-05:00 update xhtml to 3000.4.0.0 haddock-api: bump xhtml bounds haddock-api: use lazy text instead of string to support xhtml 3000.4.0.0 Bumping submodule xhtml to 3000.4.0.0 add xhtml to stage0Packages remove unused import of writeUtf8File Remove redundant import Update haddock golden files for xhtml 3000.4.0.0 Metric Decrease: haddock.Cabal haddock.base - - - - - 4da0f603 by Julian Ospald at 2025-12-05T17:01:25-05:00 rts: Fix object file format detection in loadArchive Commit 76d1041dfa4b96108cfdd22b07f2b3feb424dcbe seems to have introduced this bug, ultimately leading to failure of test T11788. I can only theorize that this test isn't run in upstream's CI, because they don't build a static GHC. The culprit is that we go through the thin archive, trying to follow the members on the filesystem, but don't re-identify the new object format of the member. This pins `object_fmt` to `NotObject` from the thin archive. Thanks to @angerman for spotting this. - - - - - 491937ec by mangoiv at 2025-12-05T17:01:31-05:00 users' guide: don't use f strings in the python script to ensure compatibility with python 3.5 - - - - - 91 changed files: - compiler/GHC/ByteCode/Linker.hs - compiler/GHC/ByteCode/Serialize.hs - compiler/GHC/CmmToAsm/LA64/CodeGen.hs - compiler/GHC/Driver/Backpack.hs - compiler/GHC/Driver/Downsweep.hs - compiler/GHC/Driver/DynFlags.hs - compiler/GHC/Driver/Errors/Ppr.hs - compiler/GHC/Driver/Errors/Types.hs - compiler/GHC/Driver/Make.hs - compiler/GHC/Driver/Phases.hs - compiler/GHC/Driver/Pipeline.hs - compiler/GHC/Driver/Session.hs - + compiler/GHC/Linker/ByteCode.hs - compiler/GHC/Linker/Loader.hs - compiler/GHC/Linker/Types.hs - compiler/GHC/Rename/Splice.hs - compiler/GHC/Runtime/Debugger.hs - compiler/GHC/Runtime/Eval.hs - compiler/GHC/Settings.hs - compiler/GHC/Tc/Solver/Monad.hs - compiler/GHC/Types/Error/Codes.hs - compiler/GHC/Unit/Home/PackageTable.hs - compiler/GHC/Unit/Info.hs - compiler/GHC/Unit/Module/Graph.hs - compiler/GHC/Unit/State.hs - compiler/ghc.cabal.in - docs/users_guide/conf.py - docs/users_guide/phases.rst - hadrian/src/Builder.hs - hadrian/src/Rules/ToolArgs.hs - hadrian/src/Settings/Builders/Ghc.hs - hadrian/src/Settings/Default.hs - libraries/ghc-boot/GHC/Unit/Database.hs - libraries/xhtml - rts/linker/LoadArchive.c - testsuite/config/ghc - testsuite/mk/boilerplate.mk - + testsuite/tests/cabal/Bytecode.hs - + testsuite/tests/cabal/BytecodeForeign.c - + testsuite/tests/cabal/BytecodeForeign.hs - testsuite/tests/cabal/Makefile - testsuite/tests/cabal/all.T - + testsuite/tests/cabal/bytecode.pkg - + testsuite/tests/cabal/bytecode.script - + testsuite/tests/cabal/bytecode_foreign.pkg - + testsuite/tests/cabal/bytecode_foreign.script - testsuite/tests/cabal/ghcpkg03.stderr - testsuite/tests/cabal/ghcpkg03.stderr-mingw32 - testsuite/tests/cabal/ghcpkg05.stderr - testsuite/tests/cabal/ghcpkg05.stderr-mingw32 - + testsuite/tests/cabal/pkg_bytecode.stderr - + testsuite/tests/cabal/pkg_bytecode.stdout - + testsuite/tests/cabal/pkg_bytecode_foreign.stderr - + testsuite/tests/cabal/pkg_bytecode_foreign.stdout - + testsuite/tests/cabal/pkg_bytecode_with_gbc.stderr - + testsuite/tests/cabal/pkg_bytecode_with_gbc.stdout - + testsuite/tests/cabal/pkg_bytecode_with_o.stderr - + testsuite/tests/cabal/pkg_bytecode_with_o.stdout - testsuite/tests/driver/bytecode-object/Makefile - testsuite/tests/driver/bytecode-object/all.T - testsuite/tests/driver/bytecode-object/bytecode_object19.stdout - + testsuite/tests/driver/bytecode-object/bytecode_object20.stdout - + testsuite/tests/driver/bytecode-object/bytecode_object21.stderr - + testsuite/tests/driver/bytecode-object/bytecode_object21.stdout - + testsuite/tests/driver/bytecode-object/bytecode_object23.stdout - + testsuite/tests/driver/bytecode-object/bytecode_object24.stdout - + testsuite/tests/th/T26568.hs - + testsuite/tests/th/T26568.stderr - testsuite/tests/th/all.T - utils/ghc-pkg/Main.hs - utils/haddock/cabal.project - utils/haddock/haddock-api/haddock-api.cabal - utils/haddock/haddock-api/src/Haddock/Backends/Hoogle.hs - utils/haddock/haddock-api/src/Haddock/Backends/Hyperlinker.hs - utils/haddock/haddock-api/src/Haddock/Backends/Hyperlinker/Renderer.hs - utils/haddock/haddock-api/src/Haddock/Backends/Xhtml.hs - utils/haddock/haddock-api/src/Haddock/Backends/Xhtml/Decl.hs - utils/haddock/haddock-api/src/Haddock/Backends/Xhtml/DocMarkup.hs - utils/haddock/haddock-api/src/Haddock/Backends/Xhtml/Layout.hs - utils/haddock/haddock-api/src/Haddock/Backends/Xhtml/Names.hs - utils/haddock/haddock-api/src/Haddock/Backends/Xhtml/Themes.hs - utils/haddock/haddock-api/src/Haddock/Backends/Xhtml/Utils.hs - utils/haddock/haddock-api/src/Haddock/Doc.hs - utils/haddock/haddock-api/src/Haddock/Utils.hs - utils/haddock/html-test/ref/Bug26.html - utils/haddock/html-test/ref/Bug298.html - utils/haddock/html-test/ref/Bug458.html - utils/haddock/html-test/ref/Nesting.html - utils/haddock/html-test/ref/TitledPicture.html - utils/haddock/html-test/ref/Unicode.html - utils/haddock/html-test/ref/Unicode2.html The diff was not included because it is too large.
