We used to check the divergence and that the number of arguments > arity.
But arity zero represents unknown arity so this was subtly broken for a long time!
We would check if the saturated function diverges, and if we applied >=arity arguments.
But for unknown arity functions any number of arguments is >=idArity.
This fixes #21440.

See the new `Note [SubDemand denotes at least one evaluation]`.
A demand `n :* sd` on a let binder `x=e` now means
> "`x` was evaluated `n` times and in any program trace it is evaluated, `e` is
> evaluated deeply in sub-demand `sd`."
The "any time it is evaluated" premise is what this patch adds. As a result,
we get better nested strictness. For example (T21081)
```hs
f :: (Bool, Bool) -> (Bool, Bool)
f pr = (case pr of (a,b) -> a /= b, True)
-- before: <MP(L,L)>
-- after: <MP(SL,SL)>
g :: Int -> (Bool, Bool)
g x = let y = let z = odd x in (z,z) in f y
```
The change in demand signature "before" to "after" allows us to case-bind `z`
here.
Similarly good things happen for the `sd` in call sub-demands `Cn(sd)`, which
allows for more eta-reduction (which is only sound with `-fno-pedantic-bottoms`,
albeit).
We also fix #21085, a surprising inconsistency with `Poly` to `Call` sub-demand
expansion.
In an attempt to fix a regression caused by less inlining due to eta-reduction
in T15426, I eta-expanded the definition of `elemIndex` and `elemIndices`, thus
fixing #21345 on the go.
The main point of this patch is that it fixes #21081 and #21133.
Annoyingly, I discovered that more precise demand signatures for join points can
transform a program into a lazier program if that join point gets floated to the
top-level, see #21392. There is no simple fix at the moment, but !5349 might.
Thus, we accept a ~5% regression in `MultiLayerModulesTH_OneShot`, where #21392
bites us in `addListToUniqDSet`. T21392 reliably reproduces the issue.
Surprisingly, ghc/alloc perf on Windows improves much more than on other jobs, by
0.4% in the geometric mean and by 2% in T16875.
Metric Increase:
MultiLayerModulesTH_OneShot
Metric Decrease:
T16875

For expressions like `(scc<cc_name> primOp#) arg1` we should also look
at arg1 to determine if we call primOp# at a fixed runtime rep.
This is what corePrep already does but CoreLint didn't yet. This patch
will bring them in sync in this regard.
It also uses tickishFloatable in CorePrep instead of CorePrep having
it's own slightly differing definition of when a tick is floatable.

The LaTeX documentation generator does not seem to have been used for
quite some time, so the LaTeX-to-Haddock preprocessing step has become a
pointless complication that makes documenting the contents of GHC.Prim
needlessly difficult. This commit replaces the LaTeX syntax with the
Haddock it would have been converted into, anyway, though with an
additional distinction: it uses single quotes in places to instruct
Haddock to generate hyperlinks to bindings. This improves the quality of
the generated output.

The following is currently rejected:
```haskell
-- F is an Applicative but not a Monad
x :: F (Int, Int)
x = do
a <- pure 0
let b = 1
pure (a, b)
```
This has bitten me multiple times. This MR contains a simple fix:
only allow a "let only" segment to be merged with the next (and not
the previous) segment. As a result, when the last one or more
statements before pure/return are `LetStmt`s, there will be one
more segment containing only those `LetStmt`s.
Note that if the `let` statement mentions a name bound previously, then
the program is still rejected, for example
```haskell
x = do
a <- pure 0
let b = a + 1
pure (a, b)
```
or the example in #18559. To support this would require a more
complex approach, but this is IME much less common than the
previous case.

There is a mis-match between the TH representation of OPAQUE pragmas and
GHC's internal representation due to how OPAQUE pragmas disallow phase
annotations. It seemed most in keeping to just fix the wired in name
issue by adding a special case to the desugaring of INLINE pragmas
rather than making TH/GHC agree with how the representation should look.

It seems like it was just an oversight to use the incorrect DynFlags
(global rather than local) when implementing these two options. Using
the local flags allows users to request these intermediate files get
cleaned up, which works fine in --make mode because
1. Interface files are stored in memory
2. Object files are only cleaned at the end of session (after link)

The splitSections transformer has been broken since -dynamic-too support
was implemented in hadrian. This is because we actually build the
dynamic way when building the dynamic way, so the predicate would always
fail.
The fix is to just always pass `split-sections` even if it doesn't do
anything for a particular way.

Rather than make the hadrian and make bindists the same it was easier to

bindists.

Implements #21424.
The RTS macros get_itbl and friends are extremely helpful during debugging.
However only a select few of those were available in the compiled RTS as actual symbols
as the rest were INLINE macros.
This commit marks all of them as EXTERN_INLINE. This will still inline them at use sites
but allow us to use their compiled counterparts during debugging.
This allows us to use things like `p get_fun_itbl(ptr)` in the gdb shell
since `get_fun_itbl` will now be available as symbol!

This adds a CI job (hackage-doc-tarball) which generates the necessary
tarballs for uploading libraries and documentation to hackage. The
release script knows to download this folder and the upload script will
also upload the release to hackage as part of the release.
The `ghc_upload_libs` script is moved from ghc-utils into .gitlab/ghc_upload_libs
There are two modes, preparation and upload.
* The `prepare` mode takes a link to a bindist and creates a folder containing the
source and doc tarballs ready to upload to hackage.
* The `upload` mode takes the folder created by prepare and performs the upload to
hackage.

We were using defaultSDocContext for pprTrace, which suppresses
lots of useful infomation. This small MR adds
GHC.Utils.Outputable.traceSDocContext
and uses it for pprTrace and pprTraceUserWarning.
traceSDocContext is a global, and hence not influenced by flags,
but that seems unavoidable. But I made the sdocPprDebug bit
controlled by unsafeHasPprDebug, since we have the latter for
exactly this purpose.

This MR fixes a bad bug, where the withDict was inlined too
vigorously, which in turn made the type-class Specialiser generate
a bogus specialisation, because it saw the same overloaded function
applied to two /different/ dictionaries.
Solution: inline `withDict` later. See (WD8) of Note [withDict]
in GHC.HsToCore.Expr
See #21575, which is fixed by this change.

When generating an SRT for a recursive group, GHC.Cmm.Info.Build.oneSRT
filters out recursive references, as described in Note [recursive SRTs].
However, doing so for static functions would be unsound, for the reason
described in Note [Invalid optimisation: shortcutting].
However, the same argument applies to static data constructor
applications, as we discovered in #20959. Fix this by ensuring that
static data constructor applications are included in recursive SRTs.
The approach here is not entirely satisfactory, but it is a starting
point.
Fixes #20959.

LlvmConfig contains information read from llvm-passes and llvm-targets
files in GHC's top directory. Reading these files is done only when
needed (i.e. when the LLVM backend is used) and cached for the whole
compiler session. This patch changes the way this is done:
- Split LlvmConfig into LlvmConfig and LlvmConfigCache
- Store LlvmConfigCache in HscEnv instead of DynFlags: there is no
good reason to store it in DynFlags. As it is fixed per session, we
store it in the session state instead (HscEnv).
- Initializing LlvmConfigCache required some changes to driver functions
such as newHscEnv. I've used the opportunity to untangle initHscEnv
from initGhcMonad (in top-level GHC module) and to move it to
GHC.Driver.Main, close to newHscEnv.
- I've also made `cmmPipeline` independent of HscEnv in order to remove
the call to newHscEnv in regalloc_unit_tests.

We previously only checked the stage 1/2 compiler
for --target support. We got away with this for quite a while but it
eventually caught up with us in #21579, where `bytestring`'s new NEON
implementation was unbuildable on Darwin due to Rosetta's seemingly
random logic for determining which executable image to execute. This
lead to a confusing failure to build `bytestring`'s cbits, when `clang`
tried to compile NEON builtins while targetting x86-64.
Fix this by checking CC_STAGE0 for --target support.

This commit adds module `GHC.Cmm.Dominators`, which provides a wrapper
around two existing algorithms in GHC: the Lengauer-Tarjan dominator
analysis from the X86 back end and the reverse postorder ordering from
the Cmm Dataflow framework. Issue #20726 proposes that we evaluate
some alternatives for dominator analysis, but for the time being, the
best path forward is simply to use the existing analysis on
`CmmGraph`s.
This commit addresses a bullet in #21200.

This firstly caused spurious output to be emitted (as evidenced by
#21555) but even worse caused a massive coercion to be attempted to be
printed (> 200k terms) which would invariably eats up all the memory of
your computer.
The good news is that removing this trace allows the program to compile
to completion, the bad news is that the program exhibits a core lint
error (on 9.0.2) but not any other releases it seems.

With this change, `Backend` becomes an abstract type
(there are no more exposed value constructors).
Decisions that were formerly made by asking "is the
current back end equal to (or different from) this named value
constructor?" are now made by interrogating the back end about
its properties, which are functions exported by `GHC.Driver.Backend`.
There is a description of how to migrate code using `Backend` in the
user guide.
Clients using the GHC API can find a backdoor to access the Backend
datatype in GHC.Driver.Backend.Internal.

We were considering all Typeable evidence to be "BuiltinInstance"s which
meant the stage restriction was going unchecked. In-fact, typeable has
evidence and so we need to apply the stage restriction.
This is
complicated by the fact we don't generate typeable evidence and the
corresponding DFunIds until after typechecking is concluded so we
introcue a new `InstanceWhat` constructor, BuiltinTypeableInstance which
records whether the evidence is going to be local or not.

This patch addresses a relatively obscure situation that arose
when chasing perf regressions in !7847, which itself is fixing
It does two things:
* SpecConstr can specialise on ($df d1 d2) dictionary arguments
* FloatOut no longer checks argument strictness
See Note [Specialising on dictionaries] in GHC.Core.Opt.SpecConstr.
A test case is difficult to construct, but it makes a big difference
in nofib/real/eff/VSM, at least when we have the patch for #21286
installed. (The latter stops worker/wrapper for dictionary arguments).
There is a spectacular, but slightly illusory, improvement in
runtime perf on T15426. I have documented the specifics in
T15426 itself.

-haddock on GHC < 9.0 is quite fragile and can result in obtuse parse errors
when it encounters invalid haddock syntax.
This has started to affect users since 297156e0b8053a28a860e7a18e1816207a59547b
enabled -haddock by default on many flavours.
Furthermore, since we don't test bootstrapping with 8.10 on CI, this problem
managed to slip throught the cracks.

The simple optimiser would sometimes fail to
beta-reduce a lambda when there were casts
in between the lambda and its arguments.
This can cause problems because we rely on
representation-polymorphic lambdas getting
beta-reduced away (for example, those
that arise from newtype constructors with
representation-polymorphic arguments, with
UnliftedNewtypes).

This patch typechecks record updates by desugaring them inside
the typechecker using the HsExpansion mechanism, and then typechecking
this desugared result.
Example:
data T p q = T1 { x :: Int, y :: Bool, z :: Char }
| T2 { v :: Char }
| T3 { x :: Int }
| T4 { p :: Float, y :: Bool, x :: Int }
| T5
The record update `e { x=e1, y=e2 }` desugars as follows
e { x=e1, y=e2 }
===>
let { x' = e1; y' = e2 } in
case e of
T1 _ _ z -> T1 x' y' z
T4 p _ _ -> T4 p y' x'
The desugared expression is put into an HsExpansion, and we typecheck
that.
The full details are given in Note [Record Updates] in GHC.Tc.Gen.Expr.

The functions `pushCoValArg` and `pushCoercionIntoLambda` could
introduce bad representation-polymorphism. Example:
type RR :: RuntimeRep
type family RR where { RR = IntRep }
type F :: TYPE RR
type family F where { F = Int# }
co = GRefl F (TYPE RR[0])
:: (F :: TYPE RR)
~# (F |> TYPE RR[0] :: TYPE IntRep)
f :: F -> ()
`pushCoValArg` would transform the unproblematic application
(f |> (co -> <()>)) (arg :: F |> TYPE RR[0])
into an application in which the argument does not have a fixed
`RuntimeRep`:
f ((arg |> sym co) :: (F :: TYPE RR))

The executablePath test strips the file extension (if any) when
comparing the query result with the expected value. This is to
handle platforms where GHC adds a file extension to the output
program file (e.g. .exe on Windows).
After the initial check, the file gets deleted (if supported).
However, it tries to delete the *stripped* filename, which is
incorrect. The test currently passes only because Windows does not
allow deleting the program while any process created from it is
alive.
Make the test program correct in general by deleting the
*non-stripped* executable filename.

executablePath support for NetBSD was added in
a172be07e3dce758a2325104a3a37fc8b1d20c9c, but the test was not
updated.
Update the test so that it works for NetBSD. This requires handling
some quirks:
- The result of getExecutablePath could include "./" segments.
Therefore use System.FilePath.equalFilePath to compare paths.
- The sysctl(2) call returns the original executable name even after
it was deleted. Add `canQueryAfterDelete :: [FilePath]` and
adjust expectations for the post-delete query accordingly.
Also add a note to the `executablePath` haddock to advise that
NetBSD behaves differently from other OSes when the file has been
deleted.
Also accept a decrease in memory usage for T16875. On Windows, the
metric is -2.2% of baseline, just outside the allowed ±2%. I don't
see how this commit could have influenced this metric, so I suppose
it's something in the CI environment.

The function breakTyVarCycle_maybe has been installed
in a dark corner of GHC to catch some gremlins (a.k.a.
occurs-check failures) who lurk
there. But it previously only caught gremlins of the
form (a ~ ... F a ...), where some of our intrepid users
have spawned gremlins of the form (G a ~ ... F (G a) ...).
This commit improves breakTyVarCycle_maybe (and renames
it to breakTyEqCycle_maybe) to catch the new gremlins.
Happily, the change is remarkably small.
The gory details are in Note [Type equality cycles].

Commit acb188e0 introduced a regression in the computation of free
variables in mdo statements, as the logic in
GHC.Rename.Expr.segmentRecStmts was slightly different depending on
whether the recursive do block corresponded to an mdo statement or
a rec statment.
This patch restores the previous computation for mdo blocks.

ARM64_RELOC_SUBTRACTOR relocations are paired with an
AMR64_RELOC_UNSIGNED relocation to implement: addend + sym1 - sym2
The linker was doing it in two steps, basically:
*addend <- *addend - sym2
*addend <- *addend + sym1
The first operation was likely to overflow. For example when the
relocation target was 32-bit and both sym1/sym2 were 64-bit addresses.
With the small memory model, (sym1-sym2) would fit in 32 bits but
(*addend-sym2) may not.
Now the linker does it in one step:
*addend <- *addend + sym1 - sym2

This patch concerns #20155, part (1)
The general idea is that since primops have curried bindings
(currently in PrimOpWrappers.hs) we don't need to eta-expand
them. But we /do/ need to eta-expand the levity-polymorphic ones,
because they /don't/ have bindings.
This patch makes a start in that direction, by identifying the
levity-polymophic primops in the PrimOpId IdDetails constructor.
For the moment, I'm still eta-expanding all primops (by saying
that hasNoBinding returns True for all primops), because of the
bug reported in #20155. But I hope that before long we can
tidy that up too, and remove the TEMPORARILY stuff in hasNoBinding.

This is a large collection of changes all relating to eta
reduction, originally triggered by #18993, but there followed
a long saga.
Specifics:
* Move state-hack stuff from GHC.Types.Id (where it never belonged)
to GHC.Core.Opt.Arity (which seems much more appropriate).
* Add a crucial mkCast in the Cast case of
GHC.Core.Opt.Arity.eta_expand; helps with T18223
* Add clarifying notes about eta-reducing to PAPs.
See Note [Do not eta reduce PAPs]
* I moved tryEtaReduce from GHC.Core.Utils to GHC.Core.Opt.Arity,
where it properly belongs. See Note [Eta reduce PAPs]
* In GHC.Core.Opt.Simplify.Utils.tryEtaExpandRhs, pull out the code for
when eta-expansion is wanted, to make wantEtaExpansion, and all that
same function in GHC.Core.Opt.Simplify.simplStableUnfolding. It was
previously inconsistent, but it's doing the same thing.
* I did a substantial refactor of ArityType; see Note [ArityType].
This allowed me to do away with the somewhat mysterious takeOneShots;
more generally it allows arityType to describe the function, leaving
its clients to decide how to use that information.
I made ArityType abstract, so that clients have to use functions
to access it.
* Make GHC.Core.Opt.Simplify.Utils.rebuildLam (was stupidly called
mkLam before) aware of the floats that the simplifier builds up, so
that it can still do eta-reduction even if there are some floats.
(Previously that would not happen.) That means passing the floats
to rebuildLam, and an extra check when eta-reducting (etaFloatOk).
* In GHC.Core.Opt.Simplify.Utils.tryEtaExpandRhs, make use of call-info
in the idDemandInfo of the binder, as well as the CallArity info. The
occurrence analyser did this but we were failing to take advantage here.
In the end I moved the heavy lifting to GHC.Core.Opt.Arity.findRhsArity;
see Note [Combining arityType with demand info], and functions
idDemandOneShots and combineWithDemandOneShots.
(These changes partly drove my refactoring of ArityType.)
* In GHC.Core.Opt.Arity.findRhsArity
* I'm now taking account of the demand on the binder to give
extra one-shot info. E.g. if the fn is always called with two
args, we can give better one-shot info on the binders
than if we just look at the RHS.
* Don't do any fixpointing in the non-recursive
case -- simple short cut.
* Trim arity inside the loop. See Note [Trim arity inside the loop]
* Make SimpleOpt respect the eta-reduction flag
(Some associated refactoring here.)
* I made the CallCtxt which the Simplifier uses distinguish between
recursive and non-recursive right-hand sides.
data CallCtxt = ... | RhsCtxt RecFlag | ...
It affects only one thing:
- We call an RHS context interesting only if it is non-recursive
see Note [RHS of lets] in GHC.Core.Unfold
* Remove eta-reduction in GHC.CoreToStg.Prep, a welcome simplification.
See Note [No eta reduction needed in rhsToBody] in GHC.CoreToStg.Prep.
Other incidental changes
* Fix a fairly long-standing outright bug in the ApplyToVal case of
GHC.Core.Opt.Simplify.mkDupableContWithDmds. I was failing to take the
tail of 'dmds' in the recursive call, which meant the demands were All
Wrong. I have no idea why this has not caused problems before now.
* Delete dead function GHC.Core.Opt.Simplify.Utils.contIsRhsOrArg

This fixes two bugs which were adding dependencies on alex/happy when
building from a source dist.
* When we try to pass `--with-alex` and `--with-happy` to cabal when
configuring but the builders are not set. This is fixed by making them
optional.
* When we configure, cabal requires alex/happy because of the
build-tool-depends fields. These are now made optional with a cabal
flag (build-tool-depends) for compiler/hpc-bin/genprimopcode.

These executables (such as hsc2hs) are built using the boot compiler and
crucially, most libraries from the global package database.
We also move other build-time executables to be built in this stage such
as linters which also cleans up which libraries end up in the global
package database. This allows us to remove hacks where linters-common is
removed from the package database when a bindist is created.
This fixes issues caused by infinite recursion due to bytestring adding
a dependency on template-haskell.

Progress towards #17957
Because of `CoreM`, I did not move the `DynFlags` and `HscEnv` to other
modules as thoroughly as I usually do. This does mean that risk of
`DynFlags` "creeping back in" is higher than it usually is.
After we do the same process to the other Core passes, and then figure
out what we want to do about `CoreM`, we can finish the job started
here.
That is a good deal more work, however, so it certainly makes sense to
land this now.

This commit redefines the structure of Splices in the AST.
We get rid of `HsSplice` which used to represent typed and untyped
splices, quasi quotes, and the result of splicing either an expression,
a type or a pattern.
Instead we have `HsUntypedSplice` which models an untyped splice or a
quasi quoter, which works in practice just like untyped splices.
The `HsExpr` constructor `HsSpliceE` which used to be constructed with
an `HsSplice` is split into `HsTypedSplice` and `HsUntypedSplice`. The
former is directly constructed with an `HsExpr` and the latter now takes
an `HsUntypedSplice`.
Both `HsType` and `Pat` constructors `HsSpliceTy` and `SplicePat` now
take an `HsUntypedSplice` instead of a `HsSplice` (remember only
/untyped splices/ can be spliced as types or patterns).
The result of splicing an expression, type, or pattern is now
comfortably stored in the extension fields `XSpliceTy`, `XSplicePat`,
`XUntypedSplice` as, respectively, `HsUntypedSpliceResult (HsType
GhcRn)`, `HsUntypedSpliceResult (Pat GhcRn)`, and `HsUntypedSpliceResult
(HsExpr GhcRn)`
Overall the TTG extension points are now better used to
make invalid states unrepresentable and model the progression between
stages better.
See Note [Lifecycle of an untyped splice, and PendingRnSplice]
and Note [Lifecycle of an typed splice, and PendingTcSplice] for more
details.

As proposed in
https://gitlab.haskell.org/ghc/ghc/-/merge_requests/7508#note_432877 and
https://gitlab.haskell.org/ghc/ghc/-/merge_requests/7508#note_434676,
`GHC.HsToCore.Ticks` is about ticks, breakpoints are separate and
backend-specific (only for the bytecode interpreter), and mix entry
writing is just for HPC.
With this split we separate out those interpreter- and HPC-specific
its, and keep the main `GHC.HsToCore.Ticks` agnostic.
Also, instead of passing the reversed list and count around, we use
`SizedSeq` which abstracts over the algorithm. This is much nicer to
avoid noise and prevents bugs.
(The bugs are not just hypothetical! I missed up the reverses on an
earlier draft of this commit.)

We used to process the rhs of non-recursive bindings and their body
using the same env. If we had something like
let x = ... x ...
this caused trouble because the two xs refer to different binders
but we would substitute both for a new binder x2 causing out of scope
errors.
We now simply use two different envs for the rhs and body in cse_bind.
It's all explained in the Note [Separate envs for let rhs and body]

This patch refactors hasFixedRuntimeRep_remainingValArgs, renaming it
to tcRemainingValArgs. The logic is moved to rebuildHsApps, which
ensures consistent behaviour across tcApp and quickLookArg1/tcEValArg.
This patch also refactors the treatment of stupid theta for data
constructors, changing the place we drop stupid theta arguments
from dsConLike to mkDataConRep (now the datacon wrapper drops these
arguments).
We decided not to implement PHASE 2 of the FixedRuntimeRep plan for
these remaining ValArgs. Future directions are outlined on the wiki:

Configure's --enable-ld-override functionality is intended to ensure
that we don't rely on ld.bfd, which tends to be slow and buggy, on
Linux and Windows. However, on Darwin the lack of sensible package
management makes it extremely easy for users to have awkward mixtures of
toolchain components from, e.g., XCode, the Apple Command-Line Tools
package, and homebrew. This leads to extremely confusing problems
like #21712.
Here we avoid this by simply giving up on linker selection on Darwin
altogether. This isn't so bad since the Apple ld64 linker has decent
performance and AFAICT fairly reliable.
Closes #21712.

The install_includes for the RTS package used to be put in the top-level
./include folder but this would lead to confusing things happening if
you installed multiple GHC versions side-by-side.
We don't need this folder anymore because install-includes
is honoured properly by cabal and the relevant header files already
copied in by the cabal installation process.
If you want to depend on the header files for the RTS in a Haskell
project then you just have to depend on the `rts` package and the
correct include directories will be provided for you.
If you want to depend on the header files in a standard C project then
you should query ghc-pkg to get the right paths.
```
ghc-pkg field rts include-dirs --simple-output
```

Previously we could construct a `Box` of a NULL pointer from the `link`
field of `StgWeak`. Now we take care to avoid ever introducing such
pointers in `collect_pointers` and ensure that the `link` field is
represented as a `Maybe` in the `Closure` type.
Fixes #21622

The recursive DFun in the reproducer for #20836 also triggered a bug in CprAnal
that is observable in a debug build. The CPR signature of a recursive DFunId
was never updated and hence the optimistic arity 0 bottom signature triggered a
mismatch with the arity 1 of the binding in WorkWrap. We never miscompiled any
code because WW doesn't exploit bottom CPR signatures.

In #20836 we have optimised a terminating program into an endless loop,
because we speculated the self-recursive call of a recursive DFun.
Now we track the set of enclosing recursive binders in CorePrep to prevent
speculation of such self-recursive calls.
See the updates to Note [Speculative evaluation] for details.

Similar to the fix to #20836 in CorePrep, we now track the set of enclosing
recursive binders in the SimplEnv and SimpleOptEnv.
See Note [Eta reduction in recursive RHSs] for details.
I also updated Note [Arity robustness] with the insights Simon and I had in a
call discussing the issue.
Fixes #21652.
Unfortunately, we get a 5% ghc/alloc regression in T16577. That is due to
additional eta reduction in GHC.Read.choose1 and the resulting ANF-isation
of a large list literal at the top-level that didn't happen before (presumably
because it was too interesting to float to the top-level). There's not much we
can do about that.

The main fix for #21667 is the new call to tcInstTypeBnders
in tcHsPartialSigType. It was really a simple omission before.
I also moved the decision about whether we need to apply the
Monomorphism Restriction, from `decideGeneralisationPlan` to
`tcPolyInfer`. That removes a flag from the InferGen constructor,
which is good.
But more importantly, it allows the new function,
checkMonomorphismRestriction
called from `tcPolyInfer`, to "see" the `Types` involved rather than
the `HsTypes`. And that in turn matters because we invoke the MR for
partial signatures if none of the partial signatures in the group have
any overloading context; and we can't answer that question for HsTypes.
See Note [Partial type signatures and the monomorphism restriction]
in GHC.Tc.Gen.Bind.
This latter is really a pre-existing bug.

These flags affect the behaviour of local let floating.
If `-flocal-float-out` is disabled (the default) then we disable all
local floating.
```
…(let x = let y = e in (a,b) in body)...
===>
…(let y = e; x = (a,b) in body)...
```
Further to this, top-level local floating can be disabled on it's own by
passing -fno-local-float-out-top-level.
```
x = let y = e in (a,b)
===>
y = e; x = (a,b)
```
Note that this is only about local floating, ie, floating two adjacent
lets past each other and doesn't say anything about the global floating
pass which is controlled by `-fno-float`.

For one by mistake I had been checking against the kind of runtime rep

This uncovered another bug, namely that we tried to generate the

a register, so this could never have worked to begin with.
This fixes #21729 and both of the above issues.

We used to put OtherCon unfoldings on lambda binders of workers
and sometimes also join points/specializations with with the
assumption that since the wrapper would force these arguments
once we execute the RHS they would indeed be in WHNF.
This was wrong for reasons detailed in #21472. So now we purge
evaluated unfoldings from *all* lambda binders.
This fixes #21472, but at the cost of sometimes not using as efficient a
calling convention. It can also change inlining behaviour as some
occurances will no longer look like value arguments when they did
before.
As consequence we also change how we compute CBV information for
arguments slightly. We now *always* determine the CBV convention
for arguments during tidy. Earlier in the pipeline we merely mark
functions as candidates for having their arguments treated as CBV.
As before the process is described in the relevant notes:
Note [CBV Function Ids]
Note [Attaching CBV Marks to ids]
Note [Never put `OtherCon` unfoldigns on lambda binders]

Previously the output from test compilations used to determine whether,
e.g., profiling libraries are available was shown with verbosity
levels >= 2. However, the default level is 2, meaning that most users
were often spammed with confusing errors. Fix this by bumping the
verbosity threshold for this output to >=3.

Noticed missing target directory dependency as a build failure in
`make --shuffle` mode (added in https://savannah.gnu.org/bugs/index.php?62100):
"cp" libraries/base/./GHC/Stack/CCS.hs-boot libraries/base/dist-install/build/GHC/Stack/CCS.hs-boot
cp: cannot create regular file 'libraries/base/dist-install/build/GHC/Stack/CCS.hs-boot': No such file or directory
libraries/haskeline/ghc.mk:4: libraries/haskeline/dist-install/build/.depend-v-p-dyn.haskell: No such file or directory
make[1]: *** [libraries/base/ghc.mk:4: libraries/base/dist-install/build/GHC/Stack/CCS.hs-boot] Error 1 shuffle=1656129254
make: *** [Makefile:128: all] Error 2 shuffle=1656129254
Note that `cp` complains about inability to create target file.
The change adds order-only dependency on a target directory (similar to
the rest of rules in that file).
The bug is lurking there since 2009 commit 34cc75e1a (`GHC new build
system megapatch`.) where upfront directory creation was never added to
`.hs-boot` files.

I think it's a recent regression caused by 0ef249aa where `system-cxx-std-lib-1.0.conf`

The fix is to consistently use `mk/system-cxx-std-lib-1.0.conf` everywhere.

BuiltInSyntax is for things which are directly constructed by the parser

We were not updating the [copied,any_work,scav_find_work, max_n_todo_overflow]

To fix this we add an `else` clause to the `if (is_par_gc())`.
The par_* counters do not need to be updated in the sequential case
because they must be 0.
