Marge Bot pushed to branch wip/marge_bot_batch_merge_job at Glasgow Haskell Compiler / GHC Commits: 6d058a69 by Andrea Bedini at 2025-05-21T16:00:51-04:00 Don't fail when ghcversion.h can't be found (#26018) If ghcversion.h can't be found, don't try to include it. This happens when there is no rts package in the package db and when -ghcversion-file argument isn't passed.

This resulted in extremely poor complexity while linking objects with lots of small sections (e.g. objects built with split sections). Rework the mechanism to instead use a simple interval set implemented via binary search. Fixes #26009. - - - - - 25358735 by Ben Gamari at 2025-05-22T20:02:19-04:00 testsuite: Add simple functional test for ProddableBlockSet - - - - - e2a354fa by Ben Gamari at 2025-05-22T20:02:19-04:00 rts/linker/PEi386: Drop check for LOAD_LIBRARY_SEARCH_*_DIRS The `LOAD_LIBRARY_SEARCH_USER_DIRS` and `LOAD_LIBRARY_SEARCH_DEFAULT_DIRS` were introduced in Windows Vista and have been available every since. As we no longer support Windows XP we can drop this check.

This ended up constituting over 40% of the runtime of `ghc --interactive -e 42` on Windows. Avoid this by maintaining a hash-set of loaded DLL names, skipping the call if we have already loaded the requested DLL.
