This modifies `splitHsApps` (a key function used in typechecking function applications) to look through untyped TH splices and quasiquotes. Not doing so was the cause of #21077. This builds on !7821 by making `splitHsApps` match on `HsUntypedSpliceTop`, which contains the `ThModFinalizers` that must be run as part of invoking the TH splice. See the new `Note [Looking through Template Haskell splices in splitHsApps]` in `GHC.Tc.Gen.Head`. Along the way, I needed to make the type of `splitHsApps.set` slightly more general to accommodate the fact that the location attached to a quasiquote is a `SrcAnn NoEpAnns` rather than a `SrcSpanAnnA`. Fixes #21077.

When the Win32 threaded IO manager shuts down, `ioManagerDie` sends an `IO_MANAGER_DIE` event to the IO manager thread using the `io_manager_event` event object. Finally, it will closes the event object, and invalidate `io_manager_event`. Previously, `readIOManagerEvent` would see that `io_manager_event` is invalid and return `0`, suggesting that everything is right with the world. This meant that if `ioManagerDie` invalidated the handle before the event manager was blocked on the event we would end up in a situation where the event manager would never realize it was asked to shut down. Fix this by ensuring that `readIOManagerEvent` instead returns `IO_MANAGER_DIE` when we detect that the event object has been invalidated by `ioManagerDie`. Fixes #23691.

This reverts commit 522bd584. And takes care of the case that I missed in my previous attempt. Namely the case of an AbsBinds with no type variables and no dictionary variable. Ironically, the comment explaining why non-recursive lets were desugared to recursive lets were pointing specifically at this case as the reason. I just failed to understand that it was until Simon PJ pointed it out to me. See #23550 for more discussion.

Warnings when building Hadrian can end up cluttering the output of HLS, and we've had bug reports in the past about these warnings when building Hadrian. It would be nice to turn on -Werror on at least one build of Hadrian in CI to avoid a patch introducing warnings when building Hadrian. Fixes #23638

This commits adds more performant Enum Int64 and Enum Word64 instances for 32-bit platforms, replacing the Integer-based implementation. These instances are a copy of the Enum Int and Enum Word instances with minimal changes to manipulate Int64 and Word64 instead. On i386 this yields a 1.5x performance increase and for the JavaScript back end it even yields a 5.6x speedup. Metric Decrease: T18964 -

When the offset doesn't fit into the immediate we now just reuse the general getRegister' code path which is well optimized to compute the offset into a register instead of a special case for CmmRegOff. This means we generate a lot less code under certain conditions which is why performance metrics for these improve. ------------------------- Metric Decrease: T4801 T5321FD T5321Fun ------------------------- -

Previously we would perform a redundant load in the non-threaded RTS in atomicModifyMutVar2# implementation for the benefit of the non-moving GC's write barrier. Eliminate this.

This allows fine-grained ignoring of warnings.
