compiler: use `UniqMap` instead of `Map` for `BCEnv` in bytecode compiler
The bytecode compiler maintains a `BCEnv` which was previously `Map Id
StackDepth`. Given `Id` is `Uniquable`, we might as well use `UniqMap`
here as a more efficient data structure, hence this patch.

Don't warn unused-imports with used generated imports
Fixes #21730
* The old notion of "implicit" import has been renamed to "generated". See Note [Generated imports] in GHC.Hs.ImpExp.
* ImportMap now keeps track of generated and user-written imports separately. This avoids the fake SrcSpan we used to give the implicit Prelude import, and the hack that went with it.
* -ddump-minimal-imports now considers generated imports (but still only
warns on + prints user-written imports)
* bestImport considers generated imports to take priority over user-written imports.

Add primop to annotate the call stack with arbitrary data
We introduce a new primop `annotateStack#` which allows us to push
arbitrary data onto the call-stack.
This allows us to extract the data later when decoding the stack, for
example when an exception is thrown, showing more information to the
user without having to annotate the full call-stack with `HasCallStack`
constraints.
A new stack frame value is introduced `AnnFrame`, which consists of
nothing but a generic payload.
The primop has a small wrapper API that allows users to annotate their
call-stack in programs.
There is a pure API and an IO-based one. The former is a little bit
dubious, as it affects the evaluation of a program, so use with care.
The latter is "safe", as it doesn't change the evaluation of the
program.
The stack annotation mechanism is similarly implemented to the
`ExceptionAnnotation` and `Exception`, there is a typeclass to indicate
something can be pushed onto the call-stack and all values are wrapped
in the existential `SomeStackAnnotation`, which recover the type of the
annotation payload.
There is currently no builtin way to show the stack annotations when
`Backtraces` are displayed (i.e., when showing stack traces to the user),
which we will address in a follow-up MR.

compiler: only use `Name` instead of `Id` in `SptEntry`
As a part of #26298, this patch refactors `SptEntry` to only carry a
`Name` instead of `Id`: we do not care about extra information like
caffyness or type at all in any static pointer related codegen logic.
This is necessary to make `SptEntry` serializable, as a part of the
grand plan of serializable bytecode.

Also refactor fetch_ghc logic in ci.sh, renaming the GHC_VERSION enviorment configuration variable to FETCH_GHC_VERSION,
making it clear that it is intended for use on platforms like Windows and FreeBSD where we don't want to use the GHC
excecutable from the platform environment and instead need to download and install GHC-$FETCH_GHC_VERSION from a release
bindist.

compiler: use zero cost coerce in GHC.CmmToAsm.CFG.loopInfo
This patch refactors GHC.CmmToAsm.CFG.loopInfo to use zero cost coerce
and thus addresses the TODO. For coerce to work, constructors of
Label/LabelMap/LabelSet from GHC.Cmm.Dataflow.Label are exposed,
though I believe it's a worthy tradeoff to avoid unnecessary runtime
cost without using unsafeCoerce, since the latter could be a landmine
for future refactoring.

Serialize wired-in names as external names when creating HIE files
Note that the domain of de-serialized names stays the same.
Specifically, for known-key names, before `lookupKnownKeyName` was used,
while now this is handled by `lookupOrigNameCache` which captures the
same range provided that the OrigNameCache has been initialized with
`knownKeyNames` (which is the case by default).

compiler: fix closure C type in SPT init code
This patch fixes the closure C type in SPT init code to StgClosure,
instead of the previously incorrect StgPtr. Having an incorrect C type
makes SPT init code not compatible with other foreign stub generation
logic, which may also emit their own extern declarations for the same
closure symbols and thus will clash with the incorrect prototypes in
SPT init code.

Adds the fucnction addDependentDirectory to Q, resolving issue #26148.
This function adds a new directory to the list of things a module depends upon. That means that when the contents of the directory change, the recompilation checker will notice this and the module will be recompiled. Documentation has also been added for addDependentFunction and addDependentDirectory in the user guide.

Generalise thNameToGhcName by adding HasHscEnv
There were multiple single monad-specific `getHscEnv` across codebase.
HasHscEnv is modelled on HasDynFlags.
My first idea was to simply add thNameToGhcNameHsc and
thNameToGhcNameTc, but those would been exactly the same
as thNameToGhcName already.
Also add an usage example to thNameToGhcName and mention that it's
recommended way of looking up names in GHC plugins

Fix deep subsumption again

Improve deep subsumption
This commit improves the DeepSubsumption sub-typing implementation
in GHC.Tc.Utils.Unify.tc_sub_type_deep by being less eager to fall back
to unification.
But alas it still wasn't quite right for view patterns: #26331
This MR does a generalisation to fix it. A bit of a sledgehammer to crack
a nut, but nice.
* Add a field `ir_inst :: InferInstFlag` to `InferResult`, where
```
data InferInstFlag = IIF_Sigma | IIF_ShallowRho | IIF_DeepRho
```
* The flag says exactly how much `fillInferResult` should instantiate
before filling the hole.
* We can also use this to replace the previous very ad-hoc `tcInferSigma`
that was used to implement GHCi's `:type` command.

Move stack decoding logic from ghc-heap to ghc-internal
The stack decoding logic in `ghc-heap` is more sophisticated than the one
currently employed in `CloneStack`. We want to use the stack decoding
implementation from `ghc-heap` in `base`.
We cannot simply depend on `ghc-heap` in `base` due do bootstrapping
issues.
Thus, we move the code that is necessary to implement stack decoding to
`ghc-internal`. This is the right location, as we don't want to add a
new API to `base`.
Moving the stack decoding logic and re-exposing it in ghc-heap is
insufficient, though, as we have a dependency cycle between.
* ghc-heap depends on stage1:ghc-internal
* stage0:ghc depends on stage0:ghc-heap
To fix this, we remove ghc-heap from the set of `stage0` dependencies.
This is not entirely straight-forward, as a couple of boot dependencies,
such as `ghci` depend on `ghc-heap`.
Luckily, the boot compiler of GHC is now >=9.10, so we can migrate `ghci`
to use `ghc-internal` instead of `ghc-heap`, which already exports the
relevant modules.
However, we cannot 100% remove ghc's dependency on `ghc-heap`, since
when we compile `stage0:ghc`, `stage1:ghc-internal` is not yet
available.
Thus, when we compile with the boot-compiler, we still depend on an
older version of `ghc-heap`, and only use the modules from `ghc-internal`,
if the `ghc-internal` version is recent enough.

size_hello_artifact
size_hello_artifact_gzip
size_hello_unicode

-------------------------
These metric increases are unfortunate, they are most likely caused by
the larger (literally in terms of lines of code) stack decoder implementation
that are now linked into hello-word binaries.
On linux, it is almost a 10% increase, which is considerable.

Fix a long standing bug in the coercion optimiser
We were mis-optimising ForAllCo, leading to #26345
Part of the poblem was the tricky tower of abstractions leading to
the dreadful
GHC.Core.TyCo.Subst.substForAllCoTyVarBndrUsing
This function was serving two masters: regular substitution, but also
coercion optimsation. So tricky was it that it did so wrong.
In this MR I locate all the fancy footwork for coercion optimisation
in GHC.Core.Coercion.Opt, where it belongs. That leaves substitution
free to be much simpler.

Expose Stack Annotation frames in IPE backtraces by default
When decoding the Haskell-native call stack and displaying the IPE information
for the stack frames, we print the `StackAnnotation` of the `AnnFrame` by default.
This means, when an exception is thrown, any intermediate stack annotations will
be displayed in the `IPE Backtrace`.
Example backtrace:
```
Exception: ghc-internal:GHC.Internal.Exception.ErrorCall:
Oh no!

Only use active rules when simplifying rule RHSs
When we are simplifying the RHS of a rule, we make sure to only apply
rewrites from rules that are active throughout the original rule's
range of active phases.
For example, if a rule is always active, we only fire rules that are
themselves always active when simplifying the RHS. Ditto for inline
activations.
This is achieved by setting the simplifier phase to a range of phases,
using the new SimplPhaseRange constructor. Then:
1. When simplifying the RHS of a rule, or of a stable unfolding,
we set the simplifier phase to a range of phases, computed from
the activation of the RULE/unfolding activation, using the
function 'phaseFromActivation'.
The details are explained in Note [What is active in the RHS of a RULE?]
in GHC.Core.Opt.Simplify.Utils.
2. The activation check for other rules and inlinings is then:
does the activation of the other rule/inlining cover the whole
phase range set in sm_phase? This continues to use the 'isActive'
function, which now accounts for phase ranges.
On the way, this commit also moves the exact-print SourceText annotation
from the Activation datatype to the ActivationAnn type. This keeps the
main Activation datatype free of any extra cruft.

debugger: Allow BRK_FUNs to head case continuation BCOs
When we start executing a BCO, we may want to yield to the scheduler:
this may be triggered by a heap/stack check, context switch, or a
breakpoint. To yield, we need to put the stack in a state such that
when execution is resumed we are back to where we yielded from.
Previously, a BKR_FUN could only head a function BCO because we only
knew how to construct a valid stack for yielding from one -- simply add
`apply_interp_info` + the BCO to resume executing. This is valid because
the stack at the start of run_BCO is headed by that BCO's arguments.
However, in case continuation BCOs (as per Note [Case continuation BCOs]),
we couldn't easily reconstruct a valid stack that could be resumed
because we dropped too soon the stack frames regarding the value
returned (stg_ret) and received (stg_ctoi) by that continuation.
This is especially tricky because of the variable type and size return
frames (e.g. pointer ret_p/ctoi_R1p vs a tuple ret_t/ctoi_t2).
The trick to being able to yield from a BRK_FUN at the start of a case
cont BCO is to stop removing the ret frame headers eagerly and instead
keep them until the BCO starts executing. The new layout at the start of
a case cont. BCO is described by the new Note [Stack layout when entering run_BCO].
Now, we keep the ret_* and ctoi_* frames when entering run_BCO.
A BRK_FUN is then executed if found, and the stack is yielded as-is with
the preserved ret and ctoi frames.
Then, a case cont BCO's instructions always SLIDE off the headers of the
ret and ctoi frames, in StgToByteCode.doCase, turning a stack like
| .... |
+---------------+
| fv2 |
+---------------+
| fv1 |
+---------------+
| BCO |
+---------------+
| stg_ctoi_ret_ |
+---------------+
| retval |
+---------------+
| stg_ret_..... |
+---------------+
into
| .... |
+---------------+
| fv2 |
+---------------+
| fv1 |
+---------------+
| retval |
+---------------+
for the remainder of the BCO.
Moreover, this more uniform approach of keeping the ret and ctoi frames
means we need less ad-hoc logic concerning the variable size of
ret_tuple vs ret_p/np frames in the code generator and interpreter:
Always keep the return to cont. stack intact at the start of run_BCO,
and the statically generated instructions will take care of adjusting
it.
Unlocks BRK_FUNs at the start of case cont. BCOs which will enable a
better user-facing step-out (#26042) which is free of the bugs the
current BRK_ALTS implementation suffers from (namely, using BRK_FUN
rather than BRK_ALTS in a case cont. means we'll never accidentally end
up in a breakpoint "deeper" than the continuation, because we stop at
the case cont itself rather than on the first breakpoint we evaluate
after it).

BRK_FUN with InternalBreakLocs for code-generation time breakpoints
At the start of a case continuation BCO, place a BRK_FUN.
This BRK_FUN uses the new "internal breakpoint location" -- allowing us
to come up with a valid source location for this breakpoint that is not associated with a source-level tick.
For case continuation BCOs, we use the last tick seen before it as the
source location. The reasoning is described in Note [Debugger: Stepout internal break locs].
Note how T26042c, which was broken because it displayed the incorrect
behavior of the previous step out when we'd end up at a deeper level
than the one from which we initiated step-out, is now fixed.
As of this commit, BRK_ALTS is now dead code and is thus dropped.
Note [Debugger: Stepout internal break locs]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Step-out tells the interpreter to run until the current function
returns to where it was called from, and stop there.
This is achieved by enabling the BRK_FUN found on the first RET_BCO
frame on the stack (See [Note Debugger: Step-out]).
Case continuation BCOs (which select an alternative branch) must
therefore be headed by a BRK_FUN. An example:
f x = case g x of <--- end up here
1 -> ...
2 -> ...
g y = ... <--- step out from here
- `g` will return a value to the case continuation BCO in `f`
- The case continuation BCO will receive the value returned from g
- Match on it and push the alternative continuation for that branch
- And then enter that alternative.
If we step-out of `g`, the first RET_BCO on the stack is the case
continuation of `f` -- execution should stop at its start, before
selecting an alternative. (One might ask, "why not enable the breakpoint
in the alternative instead?", because the alternative continuation is
only pushed to the stack *after* it is selected by the case cont. BCO)
However, the case cont. BCO is not associated with any source-level
tick, it is merely the glue code which selects alternatives which do
have source level ticks. Therefore, we have to come up at code
generation time with a breakpoint location ('InternalBreakLoc') to
display to the user when it is stopped there.
Our solution is to use the last tick seen just before reaching the case
continuation. This is robust because a case continuation will thus
always have a relevant breakpoint location:
- The source location will be the last source-relevant expression
executed before the continuation is pushed
- So the source location will point to the thing you've just stepped
out of
- Doing :step-local from there will put you on the selected
alternative (which at the source level may also be the e.g. next
line in a do-block)
Examples, using angle brackets (<<...>>) to denote the breakpoint span:
f x = case <<g x>> {- step in here -} of
1 -> ...
2 -> ...>
g y = <<...>> <--- step out from here
...
f x = <<case g x of <--- end up here, whole case highlighted
1 -> ...
2 -> ...>>
doing :step-local ...
f x = case g x of
1 -> <<...>> <--- stop in the alternative
2 -> ...
A second example based on T26042d2, where the source is a do-block IO
action, optimised to a chain of `case expressions`.
main = do
putStrLn "hello1"
<<f>> <--- step-in here
putStrLn "hello3"
putStrLn "hello4"
f = do
<<putStrLn "hello2.1">> <--- step-out from here
putStrLn "hello2.2"
...
main = do
putStrLn "hello1"
<<f>> <--- end up here again, the previously executed expression
putStrLn "hello3"
putStrLn "hello4"
doing step/step-local ...
main = do
putStrLn "hello1"
f
<<putStrLn "hello3">> <--- straight to the next line
putStrLn "hello4"
Finishes #26042

debugger: Re-use the last BreakpointId whole in step-out
Previously, to come up with a location to stop at for `:stepout`, we
would store the location of the last BreakpointId surrounding the
continuation, as described by Note [Debugger: Stepout internal break locs].
However, re-using just the location from the last source breakpoint
isn't sufficient to provide the necessary information in the break
location. Specifically, it wouldn't bind any variables at that location.
Really, there is no reason not to re-use the last breakpoint wholesale,
and re-use all the information we had there. Step-out should behave just
as if we had stopped at the call, but s.t. continuing will not
re-execute the call.
This commit updates the CgBreakInfo to always store a BreakpointId, be
it the original one or the one we're emulating (for step-out).
It makes variable bindings on :stepout work

bytecode: Don't PUSH_L 0; SLIDE 1 1
While looking through bytecode I noticed a quite common unfortunate
pattern:
...
PUSH_L 0
SLIDE 1 1
We do this often by generically constructing a tail call from a function
atom that may be somewhere arbitrary on the stack.
However, for the special case that the function can be found directly on
top of the stack, as part of the arguments, it's plain redundant to push
then slide it.
In this commit we add a small optimisation to the generation of
tailcalls in bytecode. Simply: lookahead for the function in the stack.
If it is the first thing on the stack and it is part of the arguments
which would be dropped as we entered the tail call, then don't push then
slide it.
In a simple example (T26042b), this already produced a drastic
improvement in generated code (left is old, right is with this patch):

ghc-internal: invert dependency of GHC.Internal.TH.Syntax on Data.Data
This means that Data.Data no longer blocks building TH.Syntax, which
allows greater parallelism in our builds.
We move the Data.Data.Data instances to Data.Data. Quasi depends on
Data.Data for one of its methods, so,
we split the Quasi/Q, etc definition out of GHC.Internal.TH.Syntax
into its own module. This has the added benefit of splitting up this
quite large module.
Previously TH.Syntax was a bottleneck when compiling ghc-internal. Now
it is less of a bottle-neck and is also slightly quicker to
compile (since it no longer contains these instances) at the cost of
making Data.Data slightly more expensive to compile.
TH.Lift which depends on TH.Syntax can also compile quicker and no
longer blocks ghc-internal finishing to compile.

Handle heap allocation failure in I/O primops
The current I/O managers do not use allocateMightFail, but future ones
will. To support this properly we need to be able to return to the
primop with a failure. We simply use a bool return value.
Currently however, we will just throw an exception rather than calling
the GC because that's what all the other primops do too.

Reduce detail in printThreadBlockage I/O blocking cases
The printThreadBlockage is used in debug tracing output.
For the cases BlockedOn{Read,Write,Delay} the output previously included
the fd that was being waited on, and the delay target wake time.
Superficially this sounds useful, but it's clearly not that useful
because it was already wrong for the Win32 non-threaded I/O manager. In
that situation it will print garbage (the async_result pointer, cast to
a fd or a time).
So given that it apparently never mattered that the information was
accurate, then it's hardly a big jump to say it doesn't matter if it is
present at all.
A good reason to remove it is that otherwise we have to make a new
API and a per-I/O manager implementation to fetch the information. And
for some I/O manager implementations, this information is not available.
It is not available in the win32 non-threaded I/O manager. And for some
future Linux ones, there is no need for the fd to be stored, so storing
it would be just extra space used for very little gain.
So the simplest thing is to just remove the detail.

Add TimeoutQueue.{c,h} and corresponding tests
A data structure used to efficiently manage a collection of timeouts.
It is a priority queue based on absolute expiry time. It uses 64bit
high-precision Time for the keys. The values are normal closures which
allows for example using MVars for unblocking.
It is common in many applications for timeouts to be created and then
deleted or altered before they expire. Thus the choice of data structure
for timeouts should support this efficiently. The implementation choice
here is a leftist heap with the extra feature that it supports deleting
arbitrary elements, provided the caller retain a pointer to the element.
While the deleteMin operation takes O(log n) time, as in all heap
structures, the delete operation for arbitrary elements /typically/
takes O(1), and only O(log n) in the worst case. In practice, when
managing thousands of timeouts it can be a factor of 10 faster to delete
a random timeout queue element than to remove the minimum element. This
supports the common use case.
The plan is to use it in some of the RTS-side I/O managers to support
their timer functionality. In this use case the heap value will be an
MVar used for each timeout to unblock waiting threads.

Add ClosureTable.{c,h} and corresponding tests
A table of pointers to closures on the GC heap with stable indexes.
It provides O(1) alloc, free and lookup. The table can be expanded
using a simple doubling strategy: in which case allocation is typically
O(1) and occasionally O(n) for overall amortised O(1). No shrinking is
used.
The table itself is heap allocated, and points to other heap objects.
As such it's necessary to use markClosureTable to ensure the table is
used as a GC root to keep the table entries alive, and maintain proper
pointers to them as the GC moves heap objects about.
It is designed to be allocated and accesses exclusively from a single
capability, enabling it to work without any locking. It is thus similar
to the StablePtr table, but per-capability which removes the need for
locking. It _should_ also provide lower GC pause times with the
non-moving GC by spending only O(1) time in markClosureTable, vs O(n)
for markStablePtrTable.
The plan is to use it in some of the I/O managers to keep track of
in-flight I/O operations (but not timers). This allows the tracking
info to be kept on the (unpinned) GC heap, and shared with Haskell
code, and by putting a pointer to the tracking information in a table,
the index remains stable and can be passed via foreign code (like the
kernel).

This is intended to be used by multiple I/O managers to help with
tracking in-flight I/O operations.
It is called asynchronous because from the point of view of the RTS we
have many such operations in progress at once. From the point of view of
a Haskell thread of course it can look synchronous.

Add a new I/O manager based on poll()
This is a proof of concept I/O manager, to show how to add new ones
neatly, using the ClosureTable and TimeoutQueue infrastructure.
It uses the old unix poll() API, so it is of course limited in
performance by that, but it should have the benefit of wide
compatibility. Also we neatly avoid a name clash with the existing
select() I/O manager.
Compared to the select() I/O manager:
1. beause it uses poll() it is not limited to 1024 file descriptors
(but it's still O(n) so don't expect great performance);
2. it should have much faster threadDelay (when using it in lots of
threads at once) because it's based on the new TimeoutQueue which is
O(log n) rather than O(n).
Some of the code related to timers/timouts is put into a shared module
rts/posix/Timeout.{h,c} since it is intended to be shared with other
similar I/O managers.

Use the poll() I/O manager by default

legacy select() one, if both can be enabled.
This patch is primarily for CI testing, so we should probably remove
this patch before merging. We can change defaults later after wider
testing and feedback.

Read Toolchain.Target files rather than 'settings'
This commit makes GHC read `lib/targets/default.target`, a file with a
serialized value of `ghc-toolchain`'s `GHC.Toolchain.Target`.
Moreover, it removes all the now-redundant entries from `lib/settings`
that are configured as part of a `Target` but were being written into
`settings`.
This makes it easier to support multiple targets from the same compiler
(aka runtime retargetability). `ghc-toolchain` can be re-run many times
standalone to produce a `Target` description for different targets, and,
in the future, GHC will be able to pick at runtime amongst different
`Target` files.
This commit only makes it read the default `Target` configured in-tree
or configured when installing the bindist.
The remaining bits of `settings` need to be moved to `Target` in follow
up commits, but ultimately they all should be moved since they are
per-target relevant.
Fixes #24212
On Windows, the constant overhead of parsing a slightly more complex
data structure causes some small-allocation tests to wiggle around 1 to
2 extra MB (1-2% in these cases).

ghc-toolchain: Move UseLibdw to per-Target file
To support DWARF unwinding, the RTS must be built with the -f+libdw flag
and with the -DUSE_LIBDW macro definition. These flags are passed on
build by Hadrian when --enable-dwarf-unwinding is specified at configure
time.
Whether the RTS was built with support for DWARF is a per-target
property, and as such, it was moved to the per-target
GHC.Toolchain.Target.Target file.
Additionally, we keep in the target file the include and library paths
for finding libdw, since libdw should be checked at configure time (be
it by configure, or ghc-toolchain, that libdw is properly available).
Preserving the user-given include paths for libdw facilitates in the
future building the RTS on demand for a given target (if we didn't keep
that user input, we couldn't)

Solve forall-constraints via an implication, again

Solve forall-constraints immediately, or not at all
I used a all-or-nothing strategy for quantified constraints
(aka forall-constraints). But alas that fell foul of #26315,
and #26376.
So this MR goes back to solving a quantified constraint by
turning it into an implication; UNLESS we are simplifying
constraints from a SPECIALISE pragma, in which case the
all-or-nothing strategy is great. See:
Note [Solving a Wanted forall-constraint]
Other stuff in this MR:
* TcSMode becomes a record of flags, rather than an enumeration
type; much nicer.
* Some fancy footwork to avoid error messages worsening again
(The above MR made them better; we want to retain that.)

When hadrian builds in-tree gmp, it should build the shared objects

logic in ghc-internal and shouldn't be exported by the ghc-internal
shared library. We should always strive to keep shared library symbol
table lean, which benefits platforms with slow dynamic linker or even
hard limits about how many symbols can be exported (e.g. macos dyld,
win32 dll and wasm dyld).

Use showUnique in internalAnchorIdent
Showing the key of Unique as a number is generally not a great idea.
GHC Unique has a tag in high bits, so the raw number is unnecessarily
big.
So now we have
```html
<a href="#l-rvgK"><span class="hs-identifier hs-var hs-var">bar</span></a>
```
instead of
```html
<a href="#local-6989586621679015689"><span class="hs-identifier hs-var hs-var">bar</span></a>
```
Together with previous changes of shorter intra-module links the effect
on compressed files is not huge, that is expected as we simply remove
repetitive contents which pack well.
```
12_694_206 Agda-2.9.0-docs-orig.tar.gz
12_566_065 Agda-2.9.0-docs.tar.gz
```
However when unpacked, the difference can be significant,
e.g. Agda's largest module source got 5% reduction:
```
14_230_117 Agda.Syntax.Parser.Parser.html
13_422_109 Agda.Syntax.Parser.Parser.html
```
The whole hyperlinked source code directory got similar reduction
```
121M Agda-2.9.0-docs-orig/src
114M Agda-2.9.0-docs/src
```
For the reference, sources are about 2/3 of the generated haddocks
```
178M Agda-2.9.0-docs-old
172M Agda-2.9.0-docs
```
so we get around 3.5% size reduction overall. Not bad for a small local
changes.

rts: Fix alignment for gen_workspace #26334
After a0fa4941903272c48b050d24e93eec819eff51bd bootstrap is broken on
s390x and errors out with
rts/sm/GCThread.h:207:5: error:
error: alignment of array elements is greater than element size
207 | gen_workspace gens[];
| ^~~~~~~~~~~~~
The alignment constraint is applied via the attribute to the type
gen_workspace and leaves the underlying type struct gen_workspace_
untouched. On Aarch64, x86, and s390x the struct has a size of 128
bytes. On Aarch64 and x86 the alignments of 128 and 64 are divisors of
the size, respectively, which is why the type is a viable member type
for an array. However, on s390x, the alignment is 256 and therefore is
not a divisor of the size and hence cannot be used for arrays.
Basically I see two fixes here. Either decrease the alignment
requirement on s390x, or by applying the alignment constraint on the
struct itself. The former might affect performance as noted in
a0fa4941903272c48b050d24e93eec819eff51bd. The latter introduces padding
bits whenever necessary in order to ensure that
sizeof(gen_workspace[N])==N*sizeof(gen_workspace) holds which is done by
this patch.

This patch adds a new :shell command to ghci which works similarly to
:!, except it guarantees to run the command via sh -c. On POSIX hosts
the behavior is identical to :!, but on Windows it uses the msys2
shell instead of system cmd.exe shell. This is convenient when writing
simple ghci scripts that run simple POSIX commands, and the behavior
can be expected to be coherent on both Windows and POSIX.

In particular, this ensures that the pattern-match checker, which calls

enabled. This matters for situations like:
merge :: Vec n a -> Vec n a -> Vec (2 * n) a
merge Nil Nil = Nil
merge (a <: as) (b <: bs) = a :< (b <: merge as bs)
in which we need the typechecker plugin to run in order to tell us that
the Givens would be inconsistent in the additional equation
merge (_ <: _) Nil
and thus that the equation is not needed.

InstanceMatching 4,086,884,584 1,181,767,232 -71.1% GOOD
Why? Because before we got a GIGANTIC error message that took
ages to pretty-print; now we get this much more civilised message
(I have removed some whitespace.)
Match.hs:1007:1: error:

The main payload is
* At the start of `pprExpr`
* In the defn of `pprApp`
A little bit of refactoring:
* It turned out that we were setting the default cut-off depth to a
fixed value in two places, so changing one didn't change the other.
See defaultSDocDepth and defaultSDocCols
* I refactored `pprDeeperList` a bit so I could understand it better.
Because the depth calculation has changed, there are lots of small
error message wibbles.

deriveConstants: automatically pass -fcommon CC flag (#26393)
By mistake we tried to use deriveConstants without passing
`--gcc-flag -fcommon` (which Hadrian does) and it failed.
This patch:
1. adds parsing support for constants stored in the .bss section (i.e.
when -fcommon isn't passed)
2. enables passing `-fcommon` automatically to the C compiler because
Windows requires this for subtle reasons
3. Documents the subtle reasons
(1) isn't strictly necessary because we always do (2) but it does no
harm and it is still useful if the CC flags ever contain -fno-common

This updates the user's guide section on INLINABLE pragmas to explain how

Fix tabs in string gaps (#26415)
Tabs in string gaps were broken in bb030d0d because previously, string gaps were manually parsed, but now it's lexed by the usual Alex grammar and post-processed after successful lexing.
It broke because of a discrepancy between GHC's lexer grammar and the Haskell Report. The Haskell Report includes tabs in whitechar:
whitechar → newline | vertab | space | tab | uniWhite
$whitechar used to include tabs until 18 years ago, when it was removed in order to exclude tabs from $white_no_nl in order to warn on tabs: 6e202120. In this MR, I'm adding \t back into $whitechar, and explicitly excluding \t from the $white_no_nl+ rule ignoring all whitespace in source code, which more accurately colocates the "ignore all whitespace except tabs, which is handled in the next line" logic.
As a side effect of this MR, tabs are now allowed in pragmas; currently, a pragma written as {-# \t LANGUAGE ... #-} is interpreted as the tab character being the pragma name, and GHC warns "Unrecognized pragma". With this change, tabs are ignored as whitespace, which more closely matches the Report anyway.

Remove hptAllInstances usage during upsweep
Previously, during the upsweep phase when
checking safe imports, we were loading the module
interface with runTcInteractive, which in turn calls
hptAllInstances. This accesses non-below modules
from the home package table.
Change the implementation of checkSafeImports
to use initTcWithGbl and loadSysInterface to load the
module interface, since we already have TcGblEnv at hand.
This eliminates the unnecessary use of runTcInteractive
and hptAllInstances during the upsweep phase.

rts: fix wasm JSFFI initialization constructor code
This commit fixes wasm JSFFI initialization constructor code so that
the constructor is self-contained and avoids invoking a fake
__main_argc_argv function. The previous approach of reusing
__main_void logic in wasi-libc saves a tiny bit of code, at the
expense of link-time trouble whenever GHC links a wasm module without
-no-hs-main, in which case the driver-generated main function would
clash with the definition here, resulting in a linker error. It's
simply better to avoid messing with the main function, and it would
additionally allow linking wasm32-wasi command modules that does make
use of synchronous JSFFI.

compiler/ghci: replace the LoadDLL message with LoadDLLs
As a part of #25407, this commit changes the LoadDLL message to
LoadDLLs, which takes a list of DLL paths to load and returns the list
of remote pointer handles. The wasm dyld is refactored to take
advantage of LoadDLLs and harvest background parallelism. On other
platforms, LoadDLLs is based on a fallback codepath that does
sequential loading.
The driver is not actually emitting singular LoadDLLs message with
multiple DLLs yet, this is left in subsequent commits.

- The upsweep phase sequentially loads these packages by calling
loadPackage

The lazy blackholing code in threadPaused could overwrite closures
that were already eagerly blackholed, and as such wouldn't have a

the contents of any existing blocking queue being lost.

cleanup: Drop obsolete comment about HsConDetails
HsConDetails used to have an argument representing the type of the
tyargs in a list:
data HsConDetails tyarg arg rec
= PrefixCon [tyarg] [arg]
This datatype was shared across 3 synonyms: HsConPatDetails,
HsConDeclH98Details, HsPatSynDetails. In the latter two cases, `tyarg`
was instanced to `Void` meaning the list was always empty for these
cases.
In 7b84c58867edca57a45945a20a9391724db6d9e4, this was refactored such
that HsConDetails no longer needs a type of tyargs by construction. The
first case now represents the type arguments in the args type itself,
with something like:
ConPat "MkE" [InvisP tp1, InvisP tp2, p1, p2]
So the deleted comment really is just obsolete.

`scavenge_one`, used to scavenge mutable list entries, may encounter
`WHITEHOLE`s when the non-moving GC is in use via two paths:
1. when an MVAR is being marked concurrently
2. when the object belongs to a chain of selectors being short-cutted.
Fixes #26204.

[Git][ghc/ghc][wip/fendor/t23703] Allow per constructor refinement of distinct-constructor-tables

Allow per constructor refinement of distinct-constructor-tables
Introduce `-fno-distinct-constructor-tables`. A distinct constructor table
configuration is built from the combination of flags given, in order. For
example, to only generate distinct constructor tables for a few specific
constructors and no others, just pass
`-fdistinct-constructor-tables-only=C1,...,CN`.
This flag can be supplied multiple times to extend the set of
constructors to generate a distinct info table for.
You can disable generation of distinct constructor tables for all
configurations by passing `-fno-distinct-constructor-tables`.
The various configurations of these flags is included in the `DynFlags`
fingerprints, which should result in the expected recompilation logic.
Adds a test that checks for distinct tables for various given or omitted
constructors.
Updates CountDepsAst and CountDepsParser tests to account for new dependencies.
Fixes #23703

[Git][ghc/ghc][wip/romes/26478] cleanup: Drop obsolete settings from config.mk.in

cleanup: Drop obsolete settings from config.mk.in
These values used to be spliced into the bindist's `config.mk` s.t. when
`make` was run, the values were read and written into the bindist installation `settings` file.
However, we now carry these values to the bindist directly in the
default.target toolchain file, and `make` writes almost nothing to
`settings` now (see #26227)
The entries deleted in this MR were already unused.
Fixes #26478
