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.

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.

Previously the way-specific compilation flags (e.g. `-DDEBUG`,
`-DTHREADED_RTS`) would not be passed to the CC invocations. This meant
that C dependency files would not correctly reflect
dependencies predicated on the way, resulting in the rather
painful #23554.

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:

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.
See #23550 for more discussion.

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 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.

Previously we incorrectly interpreted PE section numbers as signed
values. However, this isn't the case; rather, it's an unsigned 16-bit number
with a few special bit-patterns (0xffff and 0xfffe). This resulted in #22941
as the linker would conclude that the sections were invalid.
Fixing this required quite a bit of refactoring.
Closes #22941.

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.

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
substitution performed in tc_inst_forall_arg remains valid without
this zonking step.

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

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.

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).

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.

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.)

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:

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.

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.

We were installing two copies of the manpage:
* One useless one in the `share/doc` folder, because we copy the doc/
folder into share/
* The one we deliberately installed into `share/man` etc
The solution is to build the manpage into the `manpage` directory when
building the bindist, and then just install it separately.

This commit ensures that we emit the appropriate warnings when
a deprecated record field bound by a record wildcard is used.
For example:
module A where
data Foo = Foo {x :: Int, y :: Bool, z :: Char}
{-# DEPRECATED x "Don't use x" #-}
{-# WARNING y "Don't use y" #-}
module B where
import A
foo (Foo {..}) = x
This will cause us to emit a "Don't use x" warning, with location the
location of the record wildcard. Note that we don't warn about `y`,
because it is unused in the RHS of `foo`.

* We now represent a job group a triple of Maybes, which makes it easier
to work out when jobs are enabled/disabled on certain pipelines.
```
data JobGroup a = StandardTriple { v :: Maybe (NamedJob a)
, n :: Maybe (NamedJob a)
, r :: Maybe (NamedJob a) }
```
* `jobs-metadata.json` generation is reworked using the following
algorithm.
- For each pipeline type, find all the platforms we are doing builds
for.
- Select one build per platform
- Zip together the results
This way we can choose different pipelines for validate/nightly/release
which makes the metadata also useful for validate pipelines. This
feature is used by the test-primops downstream CI in order to select the
right bindist for testing validate pipelines.
This makes it easier to inspect which jobs are going to be enabled on a
particular pipeline.

In particular we now distinguish between whether we are dealing with a
Nightly/Release pipeline (which labels don't matter for) and a validate
pipeline where labels do matter.
The overall goal here is to allow a disjunction of labels for validate
pipelines, for example,
> Run a job if we have the full-ci label or test-primops label
Therefore the "ValidateOnly" rules are treated as a set of disjunctions
rather than conjunctions like before.
What this means in particular is that if we want to ONLY run a job if a
label is set, for example, "FreeBSD" label then we have to override the
whole label set.

At the moment we need ghc-toolchain to precisely match the output as
provided by the normal configure script. The normal configure script
(FP_HSCPP_CMD_WITH_ARGS) branches on whether we are using clang or gcc
so we match that logic exactly in ghc-toolchain.
The old implementation (which checks if certain flags are supported) is
better but for now we have to match to catch any potential errors in the
configuration.

The current user interface to configuring target toolchains is `./configure`.
In !9263 we added a new tool to configure target toolchains called
`ghc-toolchain`, but the blessed way of creating these toolchains is
still through configure.
However, we were not passing the user-specified options given with the
`./configure` invocation to the ghc-toolchain tool.
This commit remedies that by storing the user options and environment
variables in USER_* variables, which then get passed to GHC-toolchain.
The exception to the rule is the windows bundled toolchain, which
overrides the USER_* variables with whatever flags the windows bundled
toolchain requires to work.
We consider the bundled toolchain to be effectively the user specifying
options, since the actual user delegated that configuration work.
Closes #23678

On javascript there isn't a choice of toolchain but some of the
configure checks were not accurately providing the correct answer.
1. The linker was reported as gnu LD because the --version output
mentioned gnu LD.
2. The --target flag makes no sense on javascript but it was just
ignored by the linker, so we add a special case to stop ghc-toolchain
thinking that emcc supports --target when used as a linker.

On some platforms - ie darwin, javascript etc we really do not want to

a different linker.

The "format" mode takes an "--input" and "--ouput" target file and
formats it.
This is intended to be useful on windows where the
configure/ghc-toolchain target files can't be diffed very easily because
the path separators are different.

In ghc-toolchain, we were only /not/ configuring required flags when the
user specified any flags at all for the of the HsCpp and Cpp tools.
Otherwise, the linker takes into consideration the user specified flags
to determine whether to search for a better linker implementation, but
already configured the remaining GHC and platform-specific flags
regardless of the user options.
Other Tools consider the user options as a baseline for further
configuration (see `findProgram`), so #23689 is not applicable.
Closes #23689

When a class instance has an Unsatisfiable constraint in its context
and the user has not explicitly provided an implementation of a method,
we now always provide a RHS of the form `unsatisfiable @msg`, even
if the method has a default definition available. This ensures that,
when deferring type errors, users get the appropriate error message
instead of a possible runtime loop, if class default methods were
defined recursively.

The AnnSortKey is used to keep track of the order of declarations for
printing when the container has split them apart.
This applies to HsValBinds and ClassDecl, ClsInstDecl.
When making modifications to the list of declarations, the new order
must be captured for when it must be printed. For each list of
declarations (binds and sigs for a HsValBind) we can just store the
list in order.
To recreate the list when printing, we must merge them, and this is
what the AnnSortKey records. It used to be indexed by SrcSpan, we now
simply index by a marker as to which list to take the next item from.

This module defines CoreExprF -- the base functor of CoreExpr, and
equality and ordering operations on the debruijnized CoreExprF.
Furthermore, it provides a function to represent a CoreExpr in an
e-graph.
This is a requirement to represent, reason about equality, and
manipulate CoreExprs in e-graphs. E-graphs are going to be used in the
pattern match checker (#19272), and potentially for type family
rewriting (#TODO) -- amongst other oportunities that are unlocked by
having them available.

but this time with a cleaner story, since in PhiCt we already only have
ClassIds.
It works for the first two examples in #19272, but it does not solve the

of rebuilding.
RE rebuilding: It doesn't look like usually there are many/any things in
the worklist, meaning it's probably quite cheap to rebuild often.
