Marge Bot pushed to branch wip/marge_bot_batch_merge_job at Glasgow Haskell Compiler / GHC Commits: 5957a8ad by Wolfgang Jeltsch at 2026-01-27T06:11:40-05:00 Add operations for obtaining operating-system handles This contribution implements CLC proposal #369. It adds operations for obtaining POSIX file descriptors and Windows handles that underlie Haskell handles. Those operating system handles can also be obtained without such additional operations, but this is more involved and, more importantly, requires using internals. - - - - - 86a0510c by Greg Steuck at 2026-01-27T06:12:34-05:00 Move flags to precede patterns for grep and read files directly This makes the tests pass with non-GNU (i.e. POSIX-complicant) tools. There's no reason to use cat and pipe where direct file argument works. - - - - - eeabc098 by Cheng Shao at 2026-01-27T12:20:33-05:00 ci: update darwin boot ghc to 9.10.3 This patch updates darwin boot ghc to 9.10.3, along with other related updates, and pays off some technical debt here: - Update `nixpkgs` and use the `nixpkgs-25.05-darwin` channel. - Update the `niv` template. - Update LLVM to 21 and update `llvm-targets` to reflect LLVM 21 layout changes for arm64/x86_64 darwin targets. - Use `stdenvNoCC` to prevent nix packaged apple sdk from being used by boot ghc, and manually set `DEVELOPER_DIR`/`SDKROOT` to enforce the usage of system-wide command line sdk for macos. - When building nix derivation for boot ghc, run `configure` via the `arch` command so that `configure` and its subprocesses pick up the manually specified architecture. - Remove the previous horrible hack that obliterates `configure` to make autoconf test result in true. `configure` now properly does its job. - Remove the now obsolete configure args and post install settings file patching logic. - Use `scheme-small` for texlive to avoid build failures in certain unused texlive packages, especially on x86_64-darwin. - - - - - 7a6d9d44 by Matthew Pickering at 2026-01-27T12:20:34-05:00 Evaluate backtraces for "error" exceptions at the moment they are thrown See Note [Capturing the backtrace in throw] and Note [Hiding precise exception signature in throw] which explain the implementation. This commit makes `error` and `throw` behave the same with regard to backtraces. Previously, exceptions raised by `error` would not contain useful IPE backtraces. I did try and implement `error` in terms of `throw` but it started to involve putting diverging functions into hs-boot files, which seemed to risky if the compiler wouldn't be able to see if applying a function would diverge. CLC proposal: https://github.com/haskell/core-libraries-committee/issues/383 Fixes #26751 - - - - - 1516e93a by Teo Camarasu at 2026-01-27T12:20:35-05:00 ghc-internal: move all Data instances to Data.Data Most instances of Data are defined in GHC.Internal.Data.Data. Let's move all remaining instance there. This moves other modules down in the dependency hierarchy allowing for more parallelism, and it decreases the likelihood that we would need to load this heavy .hi file if we don't actually need it.
