Matthew Pickering pushed to branch wip/gbc-files at Glasgow Haskell Compiler / GHC Commits: e8c5b20d by Matthew Pickering at 2025-10-02T14:11:10+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`.
