[Git][ghc/ghc][wip/warning-for-last-and-init] 33 commits: Extend record-selector usage ticking to all binds using a record field

Bodigrim pushed to branch wip/warning-for-last-and-init at Glasgow Haskell Compiler / GHC Commits: 62899117 by Florian Ragwitz at 2025-08-13T21:01:34-04:00 Extend record-selector usage ticking to all binds using a record field This extends the previous handling of ticking for RecordWildCards and NamedFieldPuns to all var bindings that involve record selectors. Note that certain patterns such as `Foo{foo = 42}` will currently not tick the `foo` selector, as ticking is triggered by `HsVar`s. Closes #26191. - - - - - b37b3af7 by Florian Ragwitz at 2025-08-13T21:01:34-04:00 Add release notes for 9.16.1 and move description of latest HPC changes there. - - - - - a5e4b7d9 by Ben Gamari at 2025-08-13T21:02:18-04:00 rts: Clarify rationale for undefined atomic wrappers Since c06e3f46d24ef69f3a3d794f5f604cb8c2a40cbc the RTS has declared various atomic operation wrappers defined by ghc-internal as undefined. While the rationale for this isn't clear from the commit message, I believe that this is necessary due to the unregisterised backend. Specifically, the code generator will reference these symbols when compiling RTS Cmm sources. - - - - - 50842f83 by Andreas Klebinger at 2025-08-13T21:03:01-04:00 Make unexpected LLVM versions a warning rather than an error.

This API is exposed via `ghc-experimental`. By overriding how we collect `Backtraces`, we can control how the `Backtraces` are displayed to the user by newtyping `Backtraces` and giving a different instance for `ExceptionAnnotation`. A concrete use-case for this feature is allowing us to experiment with alternative stack decoders, without having to modify `base`, which take additional information from the stack frames. This commit does not modify how `Backtraces` are currently collected or displayed. - - - - - 66024722 by fendor at 2025-08-13T21:03:43-04:00 Expose Backtraces internals from ghc-experimental Additionally, expose the same API `base:Control.Exception.Backtrace` to make it easier to use as a drop-in replacement. - - - - - a766286f by Reed Mullanix at 2025-08-13T21:04:36-04:00 ghc-internal: Fix naturalAndNot for NB/NS case When the first argument to `naturalAndNot` is larger than a `Word` and the second is `Word`-sized, `naturalAndNot` will truncate the result: ```

...

...

naturalAndNot ((2 ^ 65) .|. (2 ^ 3)) (2 ^ 3) 0

In contrast, `naturalAndNot` does not truncate when both arguments are larger than a `Word`, so this appears to be a bug.
Luckily, the fix is pretty easy: we just need to call `bigNatAndNotWord#` instead of truncating.

Fixes #26230

Refactoring: Don't misuse `MCDiagnostic` for lint messages

`MCDiagnostic` is meant to be used for compiler diagnostics.

Any code that creates `MCDiagnostic` directly, without going through
`GHC.Driver.Errors.printMessage`, side steps `-fdiagnostics-as-json`
(see e.g. !14475, !14492 !14548).

To avoid this in the future I want to control more narrowly who creates
`MCDiagnostic` (see #24113).

Some parts of the compiler use `MCDiagnostic` purely for formatting
purposes, without creating any real compiler diagnostics.  This change
introduces a helper function, `formatDiagnostic`, that can be used in
such cases instead of constructing `MCDiagnostic`.

rts: ensure MessageBlackHole.link is always a valid closure

We turn a MessageBlackHole into an StgInd in wakeBlockingQueue().
Therefore it's important that the link field, which becomes the
indirection field, always points to a valid closure.

It's unclear whether it's currently possible for the previous behaviour
to lead to a crash, but it's good to be consistent about this invariant nonetheless.

rts: spin if we see a WHITEHOLE in messageBlackHole

When a BLACKHOLE gets cancelled in raiseAsync, we indirect to a THUNK.
GC can then shortcut this, replacing our BLACKHOLE with a fresh THUNK.

This THUNK is not guaranteed to have a valid indirectee field.

If at the same time, a message intended for the previous BLACKHOLE is
processed and concurrently we BLACKHOLE the THUNK, thus temporarily
turning it into a WHITEHOLE, we can get a segfault, since we look at the
undefined indirectee field of the THUNK

The fix is simple: spin if we see a WHITEHOLE, and it will soon be
replaced with a valid BLACKHOLE.

Resolves #26205

Allow defining HasField instances for naughty fields

Resolves #26295

... as HasField solver doesn't solve for fields with "naughty"

fields.

Make injecting implicit bindings into its own pass

Previously we were injecting "impliicit bindings" (data constructor
worker and wrappers etc)

  - both at the end of CoreTidy,
  - and at the start of CorePrep

This is unpleasant and confusing.  This patch puts it it its own pass,
addImplicitBinds, which runs between the two.

The function `GHC.CoreToStg.AddImplicitBinds.addImplicitBinds` now takes /all/
TyCons, not just the ones for algebraic data types.  That change ripples
through to
     - corePrepPgm
     - doCodeGen
     - byteCodeGen
All take [TyCon] which includes all TyCons

Implement unary classes

The big change is described exhaustively in

   Note [Unary class magic] in GHC.Core.TyCon

Other changes

* We never unbox class dictionaries in worker/wrapper.  This has been true for some
  time now, but the logic is now centralised in functions in
  GHC.Core.Opt.WorkWrap.Utils, namely `canUnboxTyCon`, and `canUnboxArg`
  See Note [Do not unbox class dictionaries] in GHC.Core.Opt.WorkWrap.Utils.

* Refactored the `notWorthFloating` logic in GHc.Core.Opt.SetLevels.
  I can't remember if I actually changed any behaviour here, but if so it's
  only in a corner cases.

* Fixed a bug in `GHC.Core.TyCon.isEnumerationTyCon`, which was wrongly returning
  True for (##).

* Remove redundant Role argument to `liftCoSubstWithEx`.  It was always
  Representational.

* I refactored evidence generation in the constraint solver:
  * Made GHC.Tc.Types.Evidence contain better abstactions for evidence
    generation.
  * I deleted the file `GHC.Tc.Types.EvTerm` and merged its (small) contents
    elsewhere. It wasn't paying its way.
  * Made evidence for implicit parameters go via a proper abstraction.

* Fix inlineBoringOk; see (IB6) in Note [inlineBoringOk]
  This fixes a slowdown in `countdownEffectfulDynLocal`
  in the `effectful` library.

Smaller things

* Rename `isDataTyCon` to `isBoxedDataTyCon`.
* GHC.Core.Corecion.liftCoSubstWithEx was only called with Representational role,
  so I baked that into the function and removed the argument.
* Get rid of `GHC.Core.TyCon.tyConSingleAlgDataCon_maybe` in favour of calling
  `not isNewTyCon` at the call sites; more explicit.
* Refatored `GHC.Core.TyCon.isInjectiveTyCon`; but I don't think I changed its
  behaviour
* Moved `decomposeIPPred` to GHC.Core.Predicate

Compile time performance changes:
  geo. mean        +0.1%
    minimum        -6.8%
    maximum       +14.4%

The +14% one is in T21839c, where it seems that a bit more inlining
is taking place.  That seems acceptable; and the average change is small

Metric Decrease:
    LargeRecord
    T12227
    T12707
    T16577
    T21839r
    T5642

template-haskell: move some identifiers from ghc-internal to template-haskell

These identifiers are not used internally by the compiler. Therefore we
have no reason for them to be in ghc-internal.

By moving them to template-haskell, we benefit from it being easier to
change them and we avoid having to build them in stage0.

hadrian: enforce have_llvm=False for wasm32/js

This patch fixes hadrian to always pass have_llvm=False to the
testsuite driver for wasm32/js targets. These targets don't really
support the LLVM backend, and the optllvm test way doesn't work. We
used to special-case wasm32/js to avoid auto-adding optllvm way in
testsuite/config/ghc, but this is still problematic if someone writes
a new LLVM-related test and uses something like when(have_llvm(),
extra_ways(["optllvm"])). So better just enforce have_llvm=False for
these targets here.

Re CLC issue 292 Warn GHC.Internal.List.{init,last} are partial

Also corrects the warning for `tail` to refer to `Data.List.uncons` (like the existing warning for `head`).

In module `Settings.Warnings`, applies `-Wno-unrecognised-warning-flags` `-Wno-x-partial` to the `Cabal`, `filepath`, `hsc2hs`, `hpc`, `parsec`, `text` and `time` packages (outside GHC's repository).

Also bumps submodules.
