ghc-toolchain: Toolchain Selection
This commit integrates ghc-toolchain, the brand new way of configuring
toolchains for GHC, with the Hadrian build system, with configure, and
extends and improves the first iteration of ghc-toolchain.
The general overview is
* We introduce a program invoked `ghc-toolchain --triple=...` which, when run,
produces a file with a `Target`. A `GHC.Toolchain.Target.Target`
describes the properties of a target and the toolchain (executables
and configured flags) to produce code for that target
* Hadrian was modified to read Target files, and will both
* Invoke the toolchain configured in the Target file as needed
* Produce a `settings` file for GHC based on the Target file for that stage
* `./configure` will invoke ghc-toolchain to generate target files, but
it will also generate target files based on the flags configure itself
configured (through `.in` files that are substituted)
* By default, the Targets generated by configure are still (for now) the ones used by Hadrian
* But we additionally validate the Target files generated by
ghc-toolchain against the ones generated by configure, to get a head
start on catching configuration bugs before we transition
completely.
* When we make that transition, we will want to drop a lot of the
toolchain configuration logic from configure, but keep it otherwise.
* For each compiler stage we should have 1 target file (up to a stage compiler we can't run in our machine)
* We just have a HOST target file, which we use as the target for stage0
* And a TARGET target file, which we use for stage1 (and later stages, if not cross compiling)
* Note there is no BUILD target file, because we only support cross compilation where BUILD=HOST
* (for more details on cross-compilation see discussion on !9263)

* Note [How we configure the bundled windows toolchain]

Split ghc-toolchain executable to new packge
In light of #23690, we split the ghc-toolchain executable out of the
library package to be able to ship it in the bindist using Hadrian.
Ideally, we eventually revert this commit.

Kill off gen_bytearray_addr_access_ops.py
The relevant primop descriptions are now
generated directly by genprimopcode.
This makes progress toward fixing #23490, but it is not
a complete fix since there is more than one way in which
cabal-reinstall (hadrian/build build-cabal) is broken.

Fix pretty printing of WARNING pragmas
There is still something quite unsavoury going on with WARNING pragma
printing because the printing relies on the fact that for decl
deprecations the SourceText of WarningTxt is empty. However, I let that
lion sleep and just fixed things directly.

compiler: make -ddump-asm work with wasm backend NCG
Fixes #23503.
Now the `-ddump-asm` flag is respected in the wasm backend
NCG, so developers can directly view the generated ASM instead of
needing to pass `-S` or `-keep-tmp-files` and manually find & open
the assembly file.
Ideally, we should be able to output the assembly files in smaller
chunks like in other NCG backends. This would also make dumping assembly
stats easier. However, this would require a large refactoring, so for
short-term debugging purposes I think the current approach works fine.

configure: Default missing options to False when preparing ghc-toolchain Targets
This commit fixes building ghc with 9.2 as the boostrap compiler.
The ghc-toolchain patch assumed all _STAGE0 options were available, and
forgot to account for this missing information in 9.2.
Ghc 9.2 does not have in settings whether ar supports -l, hence can't
report it with --info (unliked 9.4 upwards).
The fix is to default the missing information (we default "ar supports
-l" and other missing options to False)

This MR is an implementation of the proposal #516.
It adds a warning -Wincomplete-record-selectors for usages of a record
field access function (either a record selector or getField @"rec"),
while trying to silence the warning whenever it can be sure that a constructor
without the record field would not be invoked (which would otherwise cause
the program to fail). For example:
data T = T1 | T2 {x :: Bool}
f a = x a -- this would throw an error
g T1 = True
g a = x a -- this would not throw an error
h :: HasField "x" r Bool => r -> Bool
h = getField @"x"
j :: T -> Bool
j = h -- this would throw an error because of the `HasField`
-- constraint being solved
See the tests DsIncompleteRecSel* and TcIncompleteRecSel for more examples of the warning.
See Note [Detecting incomplete record selectors] in GHC.HsToCore.Expr for implementation details

ci: Test bootstrapping configurations with full-ci and on marge batches
There have been two incidents recently where bootstrapping has been
broken by removing support for building with 9.2.*.
The process for bumping the minimum required version starts with bumping
the configure version and then other CI jobs such as the bootstrap jobs
have to be updated. We must not silently bump the minimum required
version.
Now we are running a slimmed down validate pipeline it seems worthwile
to test these bootstrap configurations in the full-ci pipeline.

Update Match Datatype
EquationInfo currently contains a list of the equation's patterns together with a CoreExpr that is to be evaluated after a successful match on this equation.
All the match-functions only operate on the first pattern of an equation - after successfully matching it, match is called recursively on the tail of the pattern list.
We can express this more clearly and make the code a little more elegant by updating the datatype of EquationInfo as follows:
data EquationInfo
= EqnMatch { eqn_pat = Pat GhcTc, eqn_rest = EquationInfo }
| EqnDone { eqn_rhs = MatchResult CoreExpr }
An EquationInfo now explicitly exposes its first pattern which most functions operate on, and exposes the equation that remains after processing the first pattern. An EqnDone signifies an empty equation where the CoreExpr can now be evaluated.

ghc-prim: Use C11 atomics
Previously `ghc-prim`'s atomic wrappers used the legacy `__sync_*`
family of C builtins. Here we refactor these to rather use the

about the expected ordering semantics.

Make the occurrence analyser smarter about join points
This MR addresses #22404. There is a big Note
Note [Occurrence analysis for join points]
that explains it all. Significant changes
* New field occ_join_points in OccEnv
* The NonRec case of occAnalBind splits into two cases:
one for existing join points (which does the special magic for
Note [Occurrence analysis for join points], and one for other
bindings.
* mkOneOcc adds in info from occ_join_points.
* All "bring into scope" activity is centralised in the
new function `addInScope`.
* I made a local data type LocalOcc for use inside the occurrence analyser
It is like OccInfo, but lacks IAmDead and IAmALoopBreaker, which in turn
makes computationns over it simpler and more efficient.
* I found quite a bit of allocation in GHC.Core.Rules.getRules
so I optimised it a bit.
More minor changes
* I found I was using (Maybe Arity) a lot, so I defined a new data
type JoinPointHood and used it everwhere. This touches a lot of
non-occ-anal files, but it makes everything more perspicuous.
* Renamed data constructor WithUsageDetails to WUD, and
WithTailUsageDetails to WTUD
This also fixes #21128, on the way.
--------- Compiler perf -----------
I spent quite a time on performance tuning, so even though it
does more than before, the occurrence analyser runs slightly faster

In fact these figures seem to vary between platforms; generally worse
on i386 for some reason. The Windows numbers vary by 1% espec in
benchmarks where the total allocation is low. But the geom mean stays
solidly negative, which is good. The "increase/decrease" list below
covers all platforms.
The big win on T13253-spj comes because it has a big nest of join
points, each occurring twice in the next one. The new occ-anal takes
only one iteration of the simplifier to do the inlining; the old one
took four. Moreover, we get much smaller code with the new one:
New: Result size of Tidy Core
= {terms: 429, types: 84, coercions: 0, joins: 14/14}
Old: Result size of Tidy Core
= {terms: 2,437, types: 304, coercions: 0, joins: 10/10}
--------- Runtime perf -----------
No significant changes in nofib results, except a 1% reduction in
compiler allocation.

Implementation of the Deprecated Instances proposal #575
This commit implements the ability to deprecate certain instances,
which causes the compiler to emit the desired deprecation message
whenever they are instantiated. For example:
module A where
class C t where
instance {-# DEPRECATED "dont use" #-} C Int where
module B where
import A
f :: C t => t
f = undefined
g :: Int
g = f -- "dont use" emitted here
The implementation is as follows:
- In the parser, we parse deprecations/warnings attached to instances:
instance {-# DEPRECATED "msg" #-} Show X
deriving instance {-# WARNING "msg2" #-} Eq Y
(Note that non-standalone deriving instance declarations do not support
this mechanism.)
- We store the resulting warning message in `ClsInstDecl` (respectively, `DerivDecl`).
In `GHC.Tc.TyCl.Instance.tcClsInstDecl` (respectively, `GHC.Tc.Deriv.Utils.newDerivClsInst`),
we pass on that information to `ClsInst` (and eventually store it in `IfaceClsInst` too).
- Finally, when we solve a constraint using such an instance, in
`GHC.Tc.Instance.Class.matchInstEnv`, we emit the appropriate warning
that was stored in `ClsInst`.
Note that we only emit a warning when the instance is used in a different module
than it is defined, which keeps the behaviour in line with the deprecation of
top-level identifiers.

Aarch ncg: Optimize immediate use for address calculations
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.

Native 32-bit Enum Int64/Word64 instances
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.

Desugar non-recursive lets to non-recursive lets (take 2)
This reverts commit 522bd584f71ddeda21efdf0917606ce3d81ec6cc. 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.

rts/win32: Ensure reliability of IO manager shutdown
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.

Look through TH splices in splitHsApps
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.

Adjust and clarify handling of primop effects
Fixes #17900; fixes #20195.
The existing "can_fail" and "has_side_effects" primop attributes
that previously governed this were used in inconsistent and
confusingly-documented ways, especially with regard to raising
exceptions. This patch replaces them with a single "effect"
attribute, which has four possible values: NoEffect, CanFail,
ThrowsException, and ReadWriteEffect. These are described in
Note [Classifying primop effects].
A substantial amount of related documentation has been re-drafted
for clarity and accuracy.
In the process of making this attribute format change for literally
every primop, several existing mis-classifications were detected and
corrected. One of these mis-classifications was tagToEnum#, which
is now considered CanFail; this particular fix is known to cause a
regression in performance for derived Enum instances. (See #23782.)
Fixing this is left as future work.
New primop attributes "cheap" and "work_free" were also added,
and used in the corresponding parts of GHC.Core.Utils.
In view of their actual meaning and uses, `primOpOkForSideEffects`
and `exprOkForSideEffects` have been renamed to `primOpOkToDiscard`
and `exprOkToDiscard`, respectively.

Update inert_solved_dicts for ImplicitParams
When adding an implicit parameter dictionary to the inert set, we must
make sure that it replaces any previous implicit parameter dictionaries
that overlap, in order to get the appropriate shadowing behaviour, as in
let ?x = 1 in let ?x = 2 in ?x
We were already doing this for inert_cans, but we weren't doing the same
thing for inert_solved_dicts, which lead to the bug reported in #23761.
The fix is thus to make sure that, when handling an implicit parameter
dictionary in updInertDicts, we update **both** inert_cans and
inert_solved_dicts to ensure a new implicit parameter dictionary
correctly shadows old ones.

This removes the zonk in GHC.Tc.Gen.App.tc_inst_forall_arg and its
accompanying Note [Visible type application zonk]. Indeed, this zonk
is no longer necessary, as we no longer maintain the invariant that
types are well-kinded without zonking; only that typeKind does not
crash; see Note [The Purely Kinded Type Invariant (PKTI)].
This commit removes this zonking step (as well as a secondary zonk),
and replaces the aforementioned Note with the explanatory
Note [Type application substitution], which justifies why the

this zonking step.

JS: Improve compatibility with recent emsdk
The JavaScript code in libraries/base/jsbits/base.js had some
hardcoded offsets for fields in structs, because we expected
the layout of the data structures to remain unchanged. Emsdk
3.1.42 changed the layout of the stat struct, breaking this
assumption, and causing code in .hsc files accessing the
stat struct to fail.
This patch improves compatibility with recent emsdk by
removing the assumption that data layouts stay unchanged:
1. offsets of fields in structs used by JavaScript code are
now computed by the configure script, so both the .js and
.hsc files will automatically use the new layout if anything
changes.
2. the distrib/configure script checks that the emsdk version
on a user's system is the same version that a bindist was
booted with, to avoid data layout inconsistencies

tcExpr: Push expected types for untyped TH splices inwards
In !10911, I deleted a `tcExpr` case for `HsUntypedSplice` in favor of a much
simpler case that simply delegates to `tcApp`. Although this passed the test
suite at the time, this was actually an error, as the previous `tcExpr` case
was critically pushing the expected type inwards. This actually matters for
programs like the one in #23796, which GHC would not accept with type inference
alone—we need full-blown type _checking_ to accept these.
I have added back the previous `tcExpr` case for `HsUntypedSplice` and now
explain why we have two different `HsUntypedSplice` cases (one in `tcExpr` and
another in `splitHsApps`) in `Note [Looking through Template Haskell splices in
splitHsApps]` in `GHC.Tc.Gen.Head`.
Fixes #23796.

Compute all emitted diagnostic codes
This commit introduces in GHC.Types.Error.Codes the function
constructorCodes :: forall diag. (...) => Map DiagnosticCode String
which computes a collection of all the diagnostic codes that correspond
to a particular type. In particular, we can compute the collection of
all diagnostic codes emitted by GHC using the invocation
constructorCodes @GhcMessage
We then make use of this functionality in the new "codes" test which
checks consistency and coverage of GHC diagnostic codes.
It performs three checks:
- check 1: all non-outdated GhcDiagnosticCode equations
are statically used.
- check 2: all outdated GhcDiagnosticCode equations
are statically unused.
- check 3: all statically used diagnostic codes are covered by
the testsuite (modulo accepted exceptions).

numberToRangedRational: fix edge cases for exp ≈ (maxBound :: Int)
Currently a negative exponent less than `minBound :: Int` results in
Infinity, which is very surprising and obviously wrong.
```
λ> read "1e-9223372036854775808" :: Double
0.0
λ> read "1e-9223372036854775809" :: Double
Infinity
```
There is a further edge case where the exponent can overflow when
increased by the number of tens places in the integer part, or
underflow when decreased by the number of leading zeros in the
fractional part if the integer part is zero:
```
λ> read "10e9223372036854775807" :: Double
0.0
λ> read "0.01e-9223372036854775808" :: Double
Infinity
```
To resolve both of these issues, perform all arithmetic and
comparisons involving the exponent in type `Integer`. This approach
also eliminates the need to explicitly check the exponent against
`maxBound :: Int` and `minBound :: Int`, because the allowed range
of the exponent (i.e. the result of `floatRange` for the target
floating point type) is certainly within those bounds.

exprIsTrivial: Factor out shared implementation
The duplication between `exprIsTrivial` and `getIdFromTrivialExpr_maybe` has
been bugging me for a long time.
This patch introduces an inlinable worker function `trivial_expr_fold` acting
as the single, shared decision procedure of triviality. It "returns" a
Church-encoded `Maybe (Maybe Id)`, so when it is inlined, it fuses to similar
code as before.
(Better code, even, in the case of `getIdFromTrivialExpr` which presently
allocates a `Just` constructor that cancels away after this patch.)

CorePrep: Eliminate EmptyCase and unsafeEqualityProof in CoreToStg instead
We eliminate EmptyCase by way of `coreToStg (Case e _ _ []) = coreToStg e` now.
The main reason is that it plays far better in conjunction with eta expansion
(as we aim to do for arguments in CorePrep, #23083), because we can discard
any arguments, `(case e of {}) eta == case e of {}`, whereas in `(e |> co) eta`
it's impossible to discard the argument.
We do also give the same treatment to unsafeCoerce proofs and treat them as
trivial iff their RHS is trivial.
It is also both much simpler to describe than the previous mechanism of emitting
an unsafe coercion and simpler to implement, removing quite a bit of commentary
and `CorePrepProv`.
In the ghc/alloc perf test `LargeRecord`, we introduce an additional Simplifier
iteration due to #17910. E.g., FloatOut produces a binding
```
lvl_s6uK [Occ=Once1] :: GHC.Types.Int
[LclId]
lvl_s6uK = GHC.Types.I# 2#
lvl_s6uL [Occ=Once1] :: GHC.Types.Any
[LclId]
lvl_s6uL
= case Unsafe.Coerce.unsafeEqualityProof ... of
{ Unsafe.Coerce.UnsafeRefl v2_i6tr -> lvl_s6uK `cast` (... v2_i6tr ...)
}
```
That occurs once and hence is pre-inlined unconditionally in the next Simplifier
pass. It's non-trivial to find a way around that, but not really harmful
otherwise. Hence we accept a 1.2% increase on some architectures.
Metric Increase:
LargeRecord

CorePrep: Eta expand arguments (#23083)
Previously, we'd only eta expand let bindings and lambdas,
now we'll also eta expand arguments such as in T23083:
```hs
g f h = f (h `seq` (h $))
```
Unless `-fpedantic-bottoms` is set, we'll now transform to
```hs
g f h = f (\eta -> h eta)
```
in CorePrep.
See the new `Note [Eta expansion of arguments in CorePrep]` for the details.
We only do this optimisation with -O2 because we saw 2-3% ghc/alloc regressions
in T4801 and T5321FD.
Fixes #23083.

Make closure boxing pure
There seems to be no need to do something complicated. However, the

Document entertainGC in test
It wasn't obvious why it's there and what its role is.
Also, increase the "entertainment level" a bit.
I checked in STG and Cmm dumps that this really generates closures (and
is not e.g. constant folded away.)

Add -finfo-table-map-with-fallback -finfo-table-map-with-stack
The -fno-info-table-map-with-stack flag omits STACK info tables from the info
table map, and the -fno-info-table-map-with-fallback flag omits info tables
with defaulted source locations from the map. In a test on the Agda codebase
the build results were about 7% smaller when both of those types of tables
were omitted.
Adds a test that verifies that passing each combination of these flags
results in the correct output for -dipe-stats, which is disabled for the js
backend since profiling is not implemented.
This commit also refactors a lot of the logic around extracting info tables
from the Cmm results and building the info table map.
This commit also fixes some issues in the users guide rst source to fix
warnings that were noticed while debugging the documentation for these flags.
Fixes #23702

changes.
Bumps haddock submodule

xhtml is added to the stage0 packages because we need a newer version to
build stage1 haddock. In normal situations we shouldn't be building
stage0 haddock but in case someone attempts to..

testsuite: Don't need haddock executable when testing stage1 compiler
This causes some unecessary things to be built when testing stage1.
Ideally we want to move to a place where a test properly declares if it
depends on an executable so we only build the ones we actually need
rather than everything.
