[Git][ghc/ghc][wip/marge_bot_batch_merge_job] 14 commits: StgToByteCode: Don't assume that data con workers are nullary

Marge Bot pushed to branch wip/marge_bot_batch_merge_job at Glasgow Haskell Compiler / GHC Commits: d1d9e39e by Ben Gamari at 2025-09-19T18:24:52-04:00 StgToByteCode: Don't assume that data con workers are nullary Previously StgToByteCode assumed that all data-con workers were of a nullary representation. This is not a valid assumption, as seen in #23210, where an unsaturated application of a unary data constructor's worker resulted in invalid bytecode. Sadly, I have not yet been able to reduce a minimal testcase for this. Fixes #23210. - - - - - 3eeecd50 by Ben Gamari at 2025-09-19T18:24:53-04:00 testsuite: Mark T23146* as unbroken - - - - - 2e73f342 by sheaf at 2025-09-19T18:24:53-04:00 Add test for #26216 - - - - - c2efb912 by Sven Tennie at 2025-09-19T18:25:36-04:00 Generate correct test header This increases convenience when copying & pasting... - - - - - d2fb811e by Sven Tennie at 2025-09-19T18:25:36-04:00 foundation test: Fix shift amount (#26248) Shift primops' results are only defined for shift amounts of 0 to word size - 1. The approach is similar to testing div-like operations (which have a constraint regarding zero operands.) This was partly vibe coded (https://github.com/supersven/ghc/pull/1) but then heavily refactored. - - - - - a62ce115 by Andreas Klebinger at 2025-09-19T18:26:18-04:00 Tweak jspace test I've given it a longer timeout, and tweaked the test file generation to speed it up a bit. Hopefully that is enough to make it constentily pass. Last but not least it now also always uses three threads. - - - - - 0f034942 by Cheng Shao at 2025-09-19T18:26:59-04:00 rts: remove obsolete CC_SUPPORTS_TLS logic This patch removes obsolete CC_SUPPORTS_TLS logic throughout the rts, given __thread is now uniformly supported by C toolchains of all platforms we currently support. - - - - - ef705655 by Cheng Shao at 2025-09-19T18:27:41-04:00 rts: remove obsolete HAS_VISIBILITY_HIDDEN logic This patch removes obsolete HAS_VISIBILITY_HIDDEN logic throughout the rts, given __attribute__((visibility("hidden"))) is uniformly supported by C toolchains of all platforms we currently support. - - - - - 9fdc1f7d by Cheng Shao at 2025-09-19T18:28:21-04:00 rts: remove -O3 pragma hack in Hash.c This patch removes an obsolete gcc pragma to specify -O3 in Hash.c. Hadrian already passes the right flag. - - - - - b8cfa8f7 by Cheng Shao at 2025-09-19T18:29:01-04:00 rts: remove obsolete COMPILING_WINDOWS_DLL logic This patch removes obsolete COMPILING_WINDOWS_DLL logic throughout the rts. They were once used for compiling to win32 DLLs, but we haven't been able to compile Haskell units to win32 DLLs for many years now, due to PE format's restriction of no more than 65536 exported symbols in a single DLL. - - - - - bb760611 by Cheng Shao at 2025-09-19T18:29:42-04:00 wasm: bump browser_wasi_shim to 0.4.2 This patch bumps the browser_wasi_shim dependency of wasm dyld script to 0.4.2. - - - - - b3a1a0ab by Cheng Shao at 2025-09-19T19:02:29-04:00 compiler: move Binary instance of Map to GHC.Utils.Binary This patch moves `Binary` instance of `Map` from `haddock-api` to `GHC.Utils.Binary`. This also allows us to remove a redundant instance defined for `NameEntityInfo`, which is a type synonym for `Map`. - - - - - c77d889a by Vladislav Zavialov at 2025-09-19T19:02:30-04:00 Fix keyword in ExplicitNamespaces error message (#26418) Consider this module header and the resulting error: {-# LANGUAGE NoExplicitNamespaces #-} module T26418 (data HeadC) where -- error: [GHC-47007] -- Illegal keyword 'type' Previously, the error message would mention 'type' (as shown above), even though the user wrote 'data'. This has now been fixed. The error location has also been corrected: it is now reported at the keyword position rather than at the position of the associated import/export item. - - - - - 88f159e2 by Cheng Shao at 2025-09-19T19:02:31-04:00 wasm: fix dyld handling for forward declared GOT.func items This patch fixes wasm shared linker's handling of forward declared GOT.func items, see linked issue for details. Also adds T26430 test to witness the fix. Fixes #26430.
