Ticket #24768 showed that the Simplifier was accidentally destroying a join point. It turned out to be that we were sending a bottoming join point to the top, accidentally abstracting over /other/ join points. Easily fixed.

Unboxed sum constructors are now defined in the `GHC.Types` module, so if you manually quote an unboxed sum (e.g., `''Sum2#`), you will get a `Name` like: ```hs GHC.Types.Sum2# ``` The `unboxedSumTypeName` function in `template-haskell`, however, mistakenly believes that unboxed sum constructors are defined in `GHC.Prim`, so `unboxedSumTypeName 2` would return an entirely different `Name`: ```hs GHC.Prim.(#|#) ``` This is a problem for Template Haskell users, as it means that they can't be sure which `Name` is the correct one. (Similarly for `unboxedSumDataName`.) This patch fixes the implementations of `unboxedSum{Type,Data}Name` to use `GHC.Types` as the module. For consistency with `unboxedTupleTypeName`, the `unboxedSumTypeName` function now uses the non-punned syntax for unboxed sums (`Sum<N>#`) as the `OccName`. Fixes #24750. -

These are testing things which are sometimes out the control of a GHC developer. Therefore we shouldn't fail CI if something about these dependencies change because we can't do anything about it. It is still useful to have these statistics for visualisation in grafana though. Ticket #24759

This patch makes use of scheduler.postTask() for JSFFI context switch when it's available. It's a more principled approach than our MessageChannel based setImmediate() implementation, and it's available in latest version of Chromium based browsers.

This patch makes the driver always merge objects with `ld -r` when possible, and only fall back to calling `ar -L` when merge objects command is unavailable. This completely reverts !8887 and !12313, given more fixes in Cabal seems to be needed to avoid breaking certain configurations and the maintainence cost is exceeding the behefits in this case :/

This small patch fixes #24726, by tracking in-scope variables properly in -drule-check. Not hard to do!

When a breakpoint is inlined, its context may change (e.g. tyvars in scope). We must take this into account and not used the breakpoint tick index as its sole identifier. Each instance of a breakpoint (even with the same tick index) now gets a different "info" index. We also need to distinguish modules: - tick module: module with the break array (tick counters, status, etc.) - info module: module having the CgBreakInfo (info at occurrence site)

- closes #24191 - adds windows_skip, wasm_skip, wasm_arch, find_so, _find_so - path_from_ghcPkg, collect_size_ghc_pkg, collect_object_size, find_non_inplace functions to testsuite - adds on_windows and req_dynamic_ghc predicate to testsuite The design is to not make the testsuite too smart and simply offload to ghc-pkg for locations of object files and directories.

In instance SDecide Nat where SZero %~ (SSucc _) = Disproved (\case) Ensure the span for the HsLam covers the full construct. Closes #24748 -
* Don't lock tvars when performing non-committal validation. * If we encounter a locked tvar don't consider it a failure. This means in-flight validation will only fail if committing at the moment of validation is *guaranteed* to fail. This prevents in-flight validation from failing spuriously if it happens in parallel on multiple threads or parallel to thread comitting.

The STM code had a coarse grained locking mode guarded by #defines that was unused. This commit removes the code.

When `framework_fail` is called before initialising testdir, it would fail with an exception reporting the testdir not being initialised instead of the actual failure. Ensure we report the actual reason for the failure instead of failing in this way. One way this can manifest is when trying to run a test that doesn't exist using `--only`

This patch enables wasm jobs for MRs with wasm label. Previously the wasm label didn't actually have any effect on the CI pipeline, and full-ci needed to be applied to run wasm jobs which was a waste of runners when working on the wasm backend, hence the fix here.
