Alan Zimmerman pushed to branch wip/az/ghc-cpp at Glasgow Haskell Compiler / GHC Commits: e650ec3e by Ben Gamari at 2025-05-23T03:42:46-04:00 base: Forward port changelog language from 9.12 - - - - - 94cd9ca4 by Ben Gamari at 2025-05-23T03:42:46-04:00 base: Fix RestructuredText-isms in changelog - - - - - 7722232c by Ben Gamari at 2025-05-23T03:42:46-04:00 base: Note strictness changes made in 4.16.0.0 Addresses #25886. - - - - - 3f4b823c by Ben Gamari at 2025-05-23T03:43:28-04:00 rts/linker: Factor out ProddableBlocks machinery - - - - - 6e23fef2 by Ben Gamari at 2025-05-23T03:43:28-04:00 rts/linker: Improve efficiency of proddable blocks structure Previously the linker's "proddable blocks" check relied on a simple linked list of spans. 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. - - - - - ea74860c by Ben Gamari at 2025-05-23T03:43:28-04:00 testsuite: Add simple functional test for ProddableBlockSet - - - - - 74c4db46 by Ben Gamari at 2025-05-23T03:43:28-04:00 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. Addresses #26009. - - - - - 972d81d6 by Ben Gamari at 2025-05-23T03:43:28-04:00 rts/linker/PEi386: Clean up code style - - - - - 8a1073a5 by Ben Gamari at 2025-05-23T03:43:28-04:00 rts/Hash: Factor out hashBuffer This is a useful helper which can be used for non-strings as well. - - - - - 44f509f2 by Ben Gamari at 2025-05-23T03:43:28-04:00 rts/linker/PEi386: Fix incorrect use of break in nested for Previously the happy path of PEi386 used `break` in a double-`for` loop resulting in redundant calls to `LoadLibraryEx`. Fixes #26052. - - - - - bfb12783 by Ben Gamari at 2025-05-23T03:43:28-04:00 rts: Correctly mark const arguments - - - - - 08469ff8 by Ben Gamari at 2025-05-23T03:43:28-04:00 rts/linker/PEi386: Don't repeatedly load DLLs Previously every DLL-imported symbol would result in a call to `LoadLibraryEx`. 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. Addresses #26009. - - - - - 823d1ccf by Ben Gamari at 2025-05-23T03:43:28-04:00 rts/linker: Expand comment describing ProddableBlockSet - - - - - e9de9e0b by Sylvain Henry at 2025-05-23T15:12:34-04:00 Remove emptyModBreaks Remove emptyModBreaks and track the absence of ModBreaks with `Maybe ModBreaks`.
