Matthew Pickering pushed to branch wip/gdc-files at Glasgow Haskell Compiler / GHC Commits: 6f56a971 by Matthew Pickering at 2025-08-21T17:41:50+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`. - - - - - 49 changed files: - compiler/GHC/ByteCode/Serialize.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/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/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/Utils/Binary.hs - compiler/ghc.cabal.in - docs/users_guide/phases.rst - docs/users_guide/separate_compilation.rst - testsuite/driver/testlib.py - testsuite/tests/driver/T5313.hs - + testsuite/tests/driver/bytecode-object/A.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_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 The diff was not included because it is too large.
