Matthew Pickering pushed to branch wip/gbc-files at Glasgow Haskell Compiler / GHC Commits: 2ce964e5 by Matthew Pickering at 2025-09-29T15:48:26+01:00 loader: Unify loadDecls and loadModuleLinkables functions These two functions nearly did the same thing. I have refactored them so that `loadDecls` now calls `loadModuleLinkables`. Fixes #26459 - - - - - 710df07e by Matthew Pickering at 2025-09-29T15:48:26+01:00 testsuite: Use ghci_ways to set ways in PackedDataCon/UnboxedTuples/UnliftedDataTypeInterp tests These tests reimplemented the logic from `valid_way` in order to determine what ways to run. It's easier to use this combination of `only_ways` and `extra_ways` to only run in GHCi ways and always run in GHCi ways. - - - - - 75ec53b1 by Matthew Pickering at 2025-09-29T15:48:26+01:00 Rename interpreterBackend to bytecodeBackend - - - - - 15caaadd by Cheng Shao at 2025-09-29T15:48:26+01:00 compiler: implement and test bytecode serialization logic - - - - - 45c182c1 by Matthew Pickering at 2025-09-29T15:48:26+01:00 Add support for generating bytecode objects This commit adds the `-fwrite-byte-code` option which makes GHC emit a `.gbc` file which contains a serialised representation of bytecode. The bytecode can be loaded by the compiler to avoid having to reinterpret a module when using the bytecode interpreter (for example, in GHCi). There are also the new options: * -gbcdir=<DIR>: Specify the directory to place the gbc files * -gbcsuf=<suffix>: Specify the suffix for gbc files The option `-fbyte-code-and-object-code` now implies `-fwrite-byte-code`. - - - - - dcf34e9b by Matthew Pickering at 2025-09-29T15:48:26+01:00 Remove LazyBCOs - - - - - 990f9017 by Matthew Pickering at 2025-09-29T15:48:26+01:00 Print path to .gbc file if it's generated. - - - - - b6e55e55 by Matthew Pickering at 2025-09-29T15:48:26+01:00 Normalised ghci output - - - - - a8a02f5b by Matthew Pickering at 2025-09-29T15:48:26+01:00 Fix loading of objects - - - - - 8daa6957 by Matthew Pickering at 2025-09-29T15:48:26+01:00 Add performance test for consuming bytecode files - - - - - f40fb19b by Matthew Pickering at 2025-09-29T15:48:26+01:00 gbc files - - - - - 73 changed files: - compiler/GHC.hs - compiler/GHC/Builtin/PrimOps.hs - compiler/GHC/ByteCode/Breakpoints.hs - + compiler/GHC/ByteCode/Serialize.hs - compiler/GHC/ByteCode/Types.hs - compiler/GHC/Data/FlatBag.hs - compiler/GHC/Data/SmallArray.hs - compiler/GHC/Driver/Backend.hs - compiler/GHC/Driver/Backend/Internal.hs - compiler/GHC/Driver/Backpack.hs - + compiler/GHC/Driver/ByteCode.hs - compiler/GHC/Driver/Config/Finder.hs - compiler/GHC/Driver/Downsweep.hs - compiler/GHC/Driver/DynFlags.hs - compiler/GHC/Driver/Flags.hs - compiler/GHC/Driver/Main.hs - compiler/GHC/Driver/Pipeline.hs - compiler/GHC/Driver/Pipeline/Execute.hs - compiler/GHC/Driver/Session.hs - compiler/GHC/HsToCore/Breakpoints.hs - compiler/GHC/HsToCore/Usage.hs - compiler/GHC/Linker/Deps.hs - compiler/GHC/Linker/Loader.hs - compiler/GHC/Linker/Types.hs - compiler/GHC/Types/SptEntry.hs - compiler/GHC/Types/Tickish.hs - compiler/GHC/Unit/Finder.hs - compiler/GHC/Unit/Finder/Types.hs - compiler/GHC/Unit/Module/Graph.hs - compiler/GHC/Unit/Module/Location.hs - compiler/GHC/Unit/Module/ModSummary.hs - compiler/GHC/Unit/Module/WholeCoreBindings.hs - compiler/GHC/Utils/Binary.hs - compiler/ghc.cabal.in - docs/users_guide/phases.rst - docs/users_guide/separate_compilation.rst - ghc/Main.hs - testsuite/driver/testglobals.py - testsuite/driver/testlib.py - testsuite/tests/count-deps/CountDepsAst.stdout - testsuite/tests/count-deps/CountDepsParser.stdout - testsuite/tests/driver/T5313.hs - + testsuite/tests/driver/bytecode-object/A.hs - + testsuite/tests/driver/bytecode-object/BytecodeForeign.c - + testsuite/tests/driver/bytecode-object/BytecodeForeign.hs - + testsuite/tests/driver/bytecode-object/BytecodeMain.hs - + testsuite/tests/driver/bytecode-object/BytecodeTest.hs - + testsuite/tests/driver/bytecode-object/Makefile - + testsuite/tests/driver/bytecode-object/all.T - + testsuite/tests/driver/bytecode-object/bytecode_object12.stderr - + testsuite/tests/driver/bytecode-object/bytecode_object13.stdout - + testsuite/tests/driver/bytecode-object/bytecode_object14.stdout - + testsuite/tests/driver/bytecode-object/bytecode_object15.stdout - + testsuite/tests/driver/bytecode-object/bytecode_object16.stdout - + testsuite/tests/driver/bytecode-object/bytecode_object17.stdout - + testsuite/tests/driver/bytecode-object/bytecode_object18.stdout - + testsuite/tests/driver/bytecode-object/bytecode_object19.script - + testsuite/tests/driver/bytecode-object/bytecode_object19.stdout - + testsuite/tests/driver/bytecode-object/bytecode_object25.script - + testsuite/tests/driver/bytecode-object/bytecode_object25.stdout - + testsuite/tests/driver/bytecode-object/bytecode_object4.stdout - + testsuite/tests/driver/bytecode-object/bytecode_object5.stdout - + testsuite/tests/driver/bytecode-object/bytecode_object6.stdout - testsuite/tests/ghc-api/T10052/T10052.hs - testsuite/tests/ghc-api/T8639_api.hs - testsuite/tests/ghc-api/apirecomp001/myghc.hs - testsuite/tests/ghci/linking/dyn/T3372.hs - testsuite/tests/ghci/should_run/PackedDataCon/packeddatacon.T - testsuite/tests/ghci/should_run/UnboxedTuples/unboxedtuples.T - testsuite/tests/ghci/should_run/UnliftedDataTypeInterp/unlifteddatatypeinterp.T - testsuite/tests/perf/compiler/Makefile - + testsuite/tests/perf/compiler/MultiLayerModulesDefsGhciWithBytecodeFiles.script - testsuite/tests/perf/compiler/all.T The diff was not included because it is too large.
