Objects in the data section may be referenced via tagged pointers.
Thus, align those objects to a 4- or 8-byte boundary for 32- or 64-bit
platforms, respectively. Note, this may need to be reconsidered if
objects with a greater natural alignment requirement are emitted as e.g.
128-bit atomics.

EpaLocation is used to position things. It has two constructors,
EpaSpan holding a SrcSpan, and EpaDelta with a delta position and a
possible list of comments. The comment list is needed because the
location in EpaDelta has no absolute information to decide which
comments should be emitted before them when printing.
But it is also used for specifying the position of a comment. To
prevent the absurdity of a comment position having a list of comments
in it, we make EpaLocation parameterisable, using comments for the
normal case and a constant for within comments.

This patch implements the T2T (term-to-type) transformation in patterns.
Patterns that are checked against a visible forall can now be written
without the `type` keyword:
\(type t) (x :: t) -> ... -- old
\t (x :: t) -> ... -- new
The `t` binder is parsed and renamed as a term pattern (Pat), but
then undergoes a conversion to a type pattern (HsTyPat).

For expediency, the initial implementation of linear types in GHC
made it so that let and where binders would always be considered
unrestricted. This was rather unpleasant, and probably a big obstacle
to adoption. At any rate, this was not how the proposal was designed.
This patch fixes this infelicity. It was surprisingly difficult to
build, which explains, in part, why it took so long to materialise.
As of this patch, let or where bindings marked with %1 will be
linear (respectively %p for an arbitrary multiplicity p). Unmarked let
will infer their multiplicity.
Here is a prototypical example of program that used to be rejected and
is accepted with this patch:
```haskell
f :: A %1 -> B
g :: B %1 -> C
h :: A %1 -> C
h x = g y
where
y = f x
```
Exceptions:
- Recursive let are unrestricted, as there isn't a clear semantics of
what a linear recursive binding would be.
- Destructive lets with lazy bindings are unrestricted, as their
desugaring isn't linear (see also #23461).
- (Strict) destructive lets with inferred polymorphic type are
unrestricted. Because the desugaring isn't linear (See #18461
down-thread).
Closes #18461 and #18739

Apparently the check was essentially always (as far as I can trace back: d0d47ba76f8f0501cf3c4966bc83966ab38cac27),
and while it does catch some mismatches, the type-checker will catch
them too. OTOH, it prevents writing completely reasonable programs.

XCODE_VERSION calls out to `xcodebuild`, which is only available
when having `Xcode` installed. The CommandLineTools are not
sufficient. To install Xcode, you must have an apple id to download
the Xcode.xip from apple.
We do not use xcodebuild anywhere in our build explicilty. At best
it appears to be a proxy for checking the linker or the compiler.
These should rather be done with
```
xcrun ld -version
```
or similar, and not by proxy through Xcode. The CLR should be
sufficient for building software on macOS.

Previously we attempted to ensure soundness of concurrent thunk update
by synchronizing on the access of the thunk's info table pointer field.
This was believed to be sufficient since the indirectee (which may
expose a closure allocated by another core) would not be examined
until the info table pointer update is complete.
However, it turns out that this can result in data races in the presence
of multiple threads racing a update a single thunk. For instance,
consider this interleaving under the old scheme:
Thread A Thread B
--------- ---------
t=0 Enter t
1 Push update frame
2 Begin evaluation
4 Pause thread
5 t.indirectee=tso
6 Release t.info=BLACKHOLE
7 ... (e.g. GC)
8 Resume thread
9 Finish evaluation
10 Relaxed t.indirectee=x
11 Load t.info
12 Acquire fence
13 Inspect t.indirectee
14 Release t.info=BLACKHOLE
Here Thread A enters thunk `t` but is soon paused, resulting in `t`
being lazily blackholed at t=6. Then, at t=10 Thread A finishes
evaluation and updates `t.indirectee` with a relaxed store.
Meanwhile, Thread B enters the blackhole. Under the old scheme this
would introduce an acquire-fence but this would only synchronize with
Thread A at t=6. Consequently, the result of the evaluation, `x`, is not
visible to Thread B, introducing a data race.
We fix this by treating the `indirectee` field as we do all other
mutable fields. This means we must always access this field with
acquire-loads and release-stores.
See #23185.

Previously the remaining use of the C implementation on 32-bit platforms
resulted in a subtle bug, #24261. This was due to the C object (which
used the RTS's `atomic_inc64` macro) being compiled without `-threaded`
yet later being used in a threaded compiler.
Side-step this issue by using the pure Haskell `genSym` implementation on
all platforms. This required implementing `fetchAddWord64Addr#` in terms
of CAS on 64-bit platforms.

StgConApp stored a list of types. This list was used exclusively

However, this is at a wrong level of abstraction:
STG shouldn't be concerned with Haskell types, only PrimReps.
Update the code to store a [[PrimRep]]. Also, there's no point in storing
this list when we're not dealing with an unboxed sum.

Earlier, we used to pass all preprocessor flags to the c++ compiler.
This meant that -DPROFILING was passed to the c++ compiler because
it was a part of C++ flags
However, this was incorrect and the behaviour was changed in
8ff3134ed4aa323b0199ad683f72165e51a59ab6. See #21291.
But that commit exposed this bug where -DPROFILING was no longer being passed
when compiling c++ sources.
The fix is to explicitly include -DPROFILING in `opt_cxx` when profiling is
enabled to ensure we pass the correct options for the way to both C and C++
compilers

In #24296, we had a program in which we eta expanded away an error despite the
presence of `-fpedantic-bottoms`.
This was caused by turning called *at least once* lambdas into one-shot lambdas,
while with `-fpedantic-bottoms` it is only sound to eta expand over lambdas that
are called *exactly* once.
An example can be found in `Note [Combining arity type with demand info]`.

* Detect undefined labels. This can be tested by adding :ref:`nonexistent`
to a documentation rst file; attempting to build docs will fail.
Fixed the undefined label in `9.8.1-notes.rst`.
* Detect errors. While we have plenty of warnings, we can at least enforce
that Sphinx does not report errors.
Fixed the error in `required_type_arguments.rst`.
Unrelated change: I have documented that the `-dlint` enables
`-fcatch-nonexhaustive-cases`, as can be verified by checking
`enableDLint`.

Using the functionality provided by
d89deeba47ce04a5198a71fa4cbc203fe2c90794, this patch creates a new rts
flag `--no-automatic-time-samples` which disables the time profiling
when starting a program. It is then expected that the user starts it
whenever it is needed.

We were missing the extra_comma from the calculation of the size of the
payload of postIPE. This was causing assertion failures when the event
would overflow the buffer by one byte, as ensureRoomForVariable event
would report there was enough space for `n` bytes but then we would
write `n + 1` bytes into the buffer.

This MR makes three improvements to SpecConstr: see #24282
* It fixes an outright (and recently-introduced) bug in `betterPat`, which
was wrongly forgetting to compare the lengths of the argument lists.
* It enhances ConVal to inclue a boolean for work-free-ness, so that the
envt can contain non-work-free constructor applications, so that we
can do more: see Note [ConVal work-free-ness]
* It rejigs `subsumePats` so that it doesn't reverse the list. This can
make a difference because, when patterns overlap, we arbitrarily pick
the first. There is no "right" way, but this retains the old
pre-subsumePats behaviour, thereby "fixing" the regression in #24282.

The comment claims that `simpleUserHooks` decrease verbosity, and it
does, but only for the `postConf` phase. The other phases are too
verbose with `-V`.
At the moment > 5000 lines of the build log are devoted to output from
`cabal copy`.
So I take the simple approach and just decrease the verbosity level
again.
If the output of `postConf` is essential then it would be better to
implement our own `UserHooks` which doesn't decrease the verbosity for
`postConf`.

Each phase of the simplifier typically rewrites the majority of ModGuts,
so we want to be able to release the old ModGuts as soon as possible.
`name_ppr_ctxt` lives throught the whole optimiser phase and it was
retaining a reference to `ModGuts`, so we were failing to release the
old `ModGuts` until the end of the phase (potentially doubling peak
memory usage for that particular phase).
This was discovered using eras profiling (#24332)

On posix platforms, when performing read/write on FDs, we check the
nonblocking flag first. For FDs without this flag (e.g. stdout), we
call fdReady() first, which in turn calls poll() to wait for I/O to be
available on that FD. This is problematic for wasm32-wasi: although
select()/poll() is supported via the poll_oneoff() wasi syscall, that
syscall is rather heavyweight and runtime behavior differs in
different wasi implementations. The issue is even worse when targeting
browsers, given there's no satisfactory way to implement async I/O as
a synchronous syscall, so existing JS polyfills for wasi often give up
and simply return ENOSYS.
Before we have a proper I/O manager that avoids poll_oneoff() for
async I/O on wasm, this patch improves the status quo a lot by merely
pretending all FDs are "nonblocking". Read/write on FDs will directly
invoke read()/write(), which are much more reliably handled in
existing wasi implementations, especially those in browsers.

The wasm backend didn't properly make use of all Cmm global registers
due to #24347. Now that it is fixed, this patch re-enables full
register mapping for wasm32, and we can now generate smaller & faster
wasm modules that doesn't always spill arguments onto the stack. Fixes #22460 #24152.

We were emitting the wrong instructions for fused multiply-add
operations on LLVM:
- the instruction name is "llvm.fma.f32" or "llvm.fma.f64", not "fmadd"
- LLVM does not support other instructions such as "fmsub"; instead
we implement these by flipping signs of some arguments
- the instruction is an LLVM intrinsic, which requires handling it
like a normal function call instead of a machine instruction

A test *сс018* is attached (not sure about the naming convention though).
Note that without the fix, the test fails with the *dodgy-foreign-imports*
warning passed to stderr. The warning disappears after the fix.
GHC shouldn't warn on imports of natural function pointers from C by value
(which is feasible with CApiFFI), such as
```haskell
foreign import capi "cc018.h value f" f :: FunPtr (Int -> IO ())
```
where
```c
void (*f)(int);
```
See a related real-world use-case
[here](https://gitlab.com/daniel-casanueva/pcre-light/-/merge_requests/17).
There, GHC warns on import of C function pointer `pcre_free`.

This commit enables the generic cmm optimizations in other NCGs to be

optimization pass. The added optimizations do catch some corner cases

New syntax for WARNING and DEPRECATED pragmas was added,
namely namespace specifierss:
namespace_spec ::= 'type' | 'data' | {- empty -}
warning ::= warning_category namespace_spec namelist strings
deprecation ::= namespace_spec namelist strings
A new data type was introduced to represent these namespace specifiers:
data NamespaceSpecifier =
NoSpecifier |
TypeNamespaceSpecifier (EpToken "type") |
DataNamespaceSpecifier (EpToken "data")
Extension field XWarning now contains this NamespaceSpecifier.
lookupBindGroupOcc function was changed: it now takes NamespaceSpecifier
and checks that the namespace of the found names matches the passed flag.
With this change {-# WARNING data D "..." #-} pragma will only affect value
namespace and {-# WARNING type D "..." #-} will only affect type
namespace. The same logic is applicable to DEPRECATED pragmas.
Finding duplicated warnings inside rnSrcWarnDecls now takes into
consideration NamespaceSpecifier flag to allow warnings with the
same names that refer to different namespaces.

...mostly so that 16d6b7e835ffdcf9b894e79f933dd52348dedd0c
(which reworks unaligned writes in Builder) and the stuff in
https://github.com/haskell/bytestring/pull/631 can see wider testing.
The less-terrible code for unaligned writes used in Builder on
hosts not known to be ulaigned-friendly also takes less effort
for GHC to compile, resulting in a metric decrease for T21839c
on some platforms.
The metric increase on T21839r is caused by the unrelated commit
750dac33465e7b59100698a330b44de7049a345c. It perhaps warrants
further analysis and discussion (see #23822) but is not critical.
