Marge Bot pushed to branch wip/marge_bot_batch_merge_job at Glasgow Haskell Compiler / GHC Commits: 99cb9c39 by Luite Stegeman at 2026-05-28T03:10:49-04:00 Fixes for black holes - suspend duplicate work for eager black holes - detect eager black holes in checkBlockingQueues - don't overwrite existing black holes even if they're not in an eager blackhole frame - don't deadlock on self when thunk is already blackholed Fixes #26936 - - - - - 80264eb1 by Wolfgang Jeltsch at 2026-05-28T03:10:49-04:00 Allow `downsweep` to use nodes of an existing module graph To this end, `downsweep` has not been able to use the nodes of a module graph obtained from a previous downsweeping round. In some GHC API applications, downsweeping is performed somewhat incrementally and therefore could profit from reusing such existing results. This contribution makes this possible. Resolves #27054.

Note that nubOrd suffers from a small inefficiency, a fix for which will be included in the next containers release: https://github.com/haskell/containers/issues/1202 - - - - - 179e22a9 by Simon Jakobi at 2026-05-28T03:10:52-04:00 Add regression test for T11226 Closes #11226. - - - - - 35 changed files: - + changelog.d/fix-blackhole-handling - + changelog.d/module-graph-reuse-in-downsweep - compiler/GHC/CmmToAsm/BlockLayout.hs - compiler/GHC/Driver/Backpack.hs - compiler/GHC/Driver/Downsweep.hs - compiler/GHC/Driver/Make.hs - compiler/GHC/Driver/Session/Units.hs - compiler/GHC/HsToCore/Usage.hs - compiler/GHC/Linker/Unit.hs - compiler/GHC/Rename/Pat.hs - compiler/GHC/Unit/Info.hs - compiler/GHC/Unit/State.hs - compiler/GHC/Utils/Misc.hs - ghc/GHCi/UI.hs - rts/Messages.c - rts/ThreadPaused.c - rts/Threads.c - rts/Updates.h - rts/include/rts/storage/ClosureMacros.h - + testsuite/tests/ghc-api/downsweep/IncrementalDownsweep.hs - + testsuite/tests/ghc-api/downsweep/IncrementalDownsweep.modules/A.hs - + testsuite/tests/ghc-api/downsweep/IncrementalDownsweep.modules/B.hs - + testsuite/tests/ghc-api/downsweep/IncrementalDownsweep.modules/C.hs - + testsuite/tests/ghc-api/downsweep/IncrementalDownsweep.modules/D.hs - + testsuite/tests/ghc-api/downsweep/IncrementalDownsweep.modules/X.hs - + testsuite/tests/ghc-api/downsweep/IncrementalDownsweep.modules/Y.hs - + testsuite/tests/ghc-api/downsweep/IncrementalDownsweep.modules/Z.hs - + testsuite/tests/ghc-api/downsweep/IncrementalDownsweep.stdout - testsuite/tests/ghc-api/downsweep/OldModLocation.hs - testsuite/tests/ghc-api/downsweep/PartialDownsweep.hs - testsuite/tests/ghc-api/downsweep/all.T - testsuite/tests/ghc-api/fixed-nodes/InterfaceModuleGraph.hs - + testsuite/tests/perf/should_run/T11226.hs - + testsuite/tests/perf/should_run/T11226.stdout - testsuite/tests/perf/should_run/all.T The diff was not included because it is too large.
