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

On aarch64 fma is always on so the +fma flag doesn't exist for that
target. Hence no need to try and pass +fma to llvm.

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 moves GHC.CmmToAsm.cmmToCmm to a standalone module,
GHC.Cmm.GenericOpt. The main motivation is enabling this logic to be
run in the wasm backend NCG code, which is defined in other modules
that's imported by GHC.CmmToAsm, causing a cyclic dependency issue.

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

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.

In autoconf >=2.70, C11 is set by default for $CC and $CXX via the

- Fixes #18324 #20020 #23147 #22788 #15598 #22086 #21206
- The change is detailed in
- Note [Expanding HsDo with HsExpansion] in `GHC.Tc.Gen.Do`
- Note [Doing HsExpansion in the Renamer vs Typechecker] in `GHC.Rename.Expr`
expains the rational of doing expansions in type checker as opposed to in the renamer
- Adds new datatypes:
- `GHC.Hs.Expr.XXExprGhcRn`: new datatype makes this expansion work easier
1. Expansion bits for Expressions, Statements and Patterns in (`ExpandedThingRn`)
2. `PopErrCtxt` a special GhcRn Phase only artifcat to pop the previous error message in the error context stack
- `GHC.Basic.Origin` now tracks the reason for expansion in case of Generated
This is useful for type checking cf. `GHC.Tc.Gen.Expr.tcExpr` case for `HsLam`
- Kills `HsExpansion` and `HsExpanded` as we have inlined them in `XXExprGhcRn` and `XXExprGhcTc`
- Ensures warnings such as
1. Pattern match checks
2. Failable patterns
3. non-() return in body statements are preserved
- Kill `HsMatchCtxt` in favor of `TcMatchAltChecker`
- Testcases:
* T18324 T20020 T23147 T22788 T15598 T22086
* T23147b (error message check),
* DoubleMatch (match inside a match for pmc check)
* pattern-fails (check pattern match with non-refutable pattern, eg. newtype)
* Simple-rec (rec statements inside do statment)
* T22788 (code snippet from #22788)
* DoExpanion1 (Error messages for body statments)
* DoExpansion2 (Error messages for bind statements)
* DoExpansion3 (Error messages for let statements)
Also repoint haddock to the right submodule so that the test (haddockHypsrcTest) pass
Metric Increase 'compile_time/bytes allocated':
T9020
The testcase is a pathalogical example of a `do`-block with many statements that do nothing.
Given that we are expanding the statements into function binds, we will have to bear
a (small) 2% cost upfront in the compiler to unroll the statements.

This patch is a preparation for @a-binders implementation. The main changes are:
* Skolemisation is now prepared to deal with @binders.
See Note [Skolemisation overview] in GHC.Tc.Utils.Unify.
Most of the action is in
- Utils.Unify.matchExpectedFunTys
- Gen.Pat.tcMatchPats
- Gen.Expr.tcPolyExprCheck
- Gen.Binds.tcPolyCheck
Some accompanying refactoring:
* I found that funTyConAppTy_maybe was doing a lot of allocation, and

This fixes a bug in 8db8d2fd1c881032b1b360c032b6d9d072c11723, where we could lose
track of acyclic components at the start of an unresolved cycle. We now ensure we
never loose track of any of these components.
As T24275 demonstrates, a "cyclic" SCC might not really be a true SCC:
When viewed without boot files, we have a single SCC
```
[REC main:T24275B [main:T24275B {-# SOURCE #-},
main:T24275A {-# SOURCE #-}]
main:T24275A [main:T24275A {-# SOURCE #-}]]
```
But with boot files this turns into
```
[NONREC main:T24275B {-# SOURCE #-} [],
REC main:T24275B [main:T24275B {-# SOURCE #-},

```
Note that this is truly not an SCC, as no nodes are reachable from T24275B.hs-boot.
However, we treat this entire group as a single "SCC" because it seems so when we
analyse the graph without taking boot files into account.
Indeed, we must return a single ResolvedCycle element in the BuildPlan for this
as described in Note [Upsweep].
However, since after resolving this is not a true SCC anymore, `findCycle` fails
to find a cycle and we have a sub-optimal error message as a result.
To handle this, I extended `findCycle` to not assume its input is an SCC, and to
try harder to find cycles in its input.

In b521354216f2821e00d75f088d74081d8b236810 the testsuite gained the
capability to collect generic metrics. But this assumed that the test
was not linking and producing artifacts and we only wanted to track
object files, interface files, or build artifacts from the compiler
build. However, some backends, such as the JS backend, produce artifacts when
compiling, such as the jsexe directory which we want to track.
This patch:
- tweaks the testsuite to collect generic metrics on any build artifact
in the test directory.
- expands the exe_extension function to consider windows and adds the
ignore_extension flag.
- Modifies certain tests to add the ignore_extension flag. Tests such as
heaprof002 expect a .ps file, but on windows without ignore_extensions
the testsuite will look for foo.exe.ps. Hence the flag.
- adds the size_hello_artifact test

This logic appears to be incorrect as it would drop any dependency which
was not in a direct dependency of the package being linked.
In the ghc-internals split this started to cause errors because
`ghc-internal` is not a direct dependency of most packages, and hence
important symbols to keep which are hard coded into the js runtime were
getting dropped.

Here we move a good deal of the implementation of `base` into a new
package, `ghc-internal` such that it can be evolved independently
from the user-visible interfaces of `base`.
While we want to isolate implementation from interfaces, naturally, we
would like to avoid turning `base` into a mere set of module re-exports.
However, this is a non-trivial undertaking for a variety of reasons:
* `base` contains numerous known-key and wired-in things, requiring
corresponding changes in the compiler
* `base` contains a significant amount of C code and corresponding
autoconf logic, which is very fragile and difficult to break apart
* `base` has numerous import cycles, which are currently dealt with via
carefully balanced `hs-boot` files
* We must not break existing users
To accomplish this migration, I tried the following approaches:
* [Split-GHC.Base]: Break apart the GHC.Base knot to allow incremental
migration of modules into ghc-internal: this knot is simply too
intertwined to be easily pulled apart, especially given the rather
tricky import cycles that it contains)
* [Move-Core]: Moving the "core" connected component of base (roughly
150 modules) into ghc-internal. While the Haskell side of this seems
tractable, the C dependencies are very subtle to break apart.
* [Move-Incrementally]:
1. Move all of base into ghc-internal
2. Examine the module structure and begin moving obvious modules (e.g.
leaves of the import graph) back into base
3. Examine the modules remaining in ghc-internal, refactor as necessary
to facilitate further moves
4. Go to (2) iterate until the cost/benefit of further moves is
insufficient to justify continuing
5. Rename the modules moved into ghc-internal to ensure that they don't
overlap with those in base
6. For each module moved into ghc-internal, add a shim module to base
with the declarations which should be exposed and any requisite
Haddocks (thus guaranteeing that base will be insulated from changes
in the export lists of modules in ghc-internal
Here I am using the [Move-Incrementally] approach, which is empirically
the least painful of the unpleasant options above

Per #23966, I want the top-level configure to only generate
configuration data for Hadrian, not do any "real" tasks on its own.
This is part of that effort --- one less file generated by it.
(It is still done with a `.in` file, so in a future world non-Hadrian
also can easily create this file.)
Split modules:
- GHC.CmmToLlvm.Config
- GHC.CmmToLlvm.Version
- GHC.CmmToLlvm.Version.Bounds
- GHC.CmmToLlvm.Version.Type
This also means we can get rid of the silly `unused.h` introduced in
!6803 / 7dfcab2f4bcb7206174ea48857df1883d05e97a2 as temporary kludge.

The eras profiling mode is useful for tracking the life-time of
closures. When a closure is written, the current era is recorded in the
profiling header. This records the era in which the closure was created.
* Enable with -he
* User mode: Use functions ghc-experimental module GHC.Profiling.Eras to modify the era
* Automatically: --automatic-era-increment, increases the user era on major
collections
* The first era is era 1
* -he<era> can be used with other profiling modes to select a specific
era
If you just want to record the era but not to perform heap profiling you
can use `-he --no-automatic-heap-samples`.

Some Haskell codes unsafely cast StablePtr into ptr to compare against
NULL. E.g. in direct-sqlite:
if castStablePtrToPtr aggStPtr /= nullPtr then
where `aggStPtr` is read (`peek`) from zeroed memory initially.
We fix this by giving these StablePtr the same representation as other
null pointers. It's safe because StablePtr at offset 0 is unused (for
this exact reason).

Support linking C sources with JS output of the JavaScript backend.
See the added documentation in the users guide.
The implementation simply extends the JS linker to use the objects (.o)
that were already produced by the emcc compiler and which were filtered
out previously. I've also added some options to control the link with C
functions (see the documentation about pragmas).
With this change I've successfully compiled the direct-sqlite package
which embeds the sqlite.c database code. Some wrappers are still
required (see the documentation about wrappers) but everything generic
enough to be reused for other libraries have been integrated into
rts/js/mem.js.

Add support for heap profiling while using the nonmoving collector.
We greatly simply the implementation by disabling concurrent collection for
GCs when heap profiling is enabled. This entails that the marked objects on
the nonmoving heap are exactly the live objects.
Note that we match the behaviour for live bytes accounting by taking the size
of objects on the nonmoving heap to be that of the segment's block
rather than the object itself.

and emit a small complement JavaScript ESM module to be used with it
at runtime
- jsffi/prelude.js, a tiny bit of prelude code as the JavaScript side
of runtime logic
- jsffi/test-runner.mjs, run the jsffi test cases

This is used when testing the wasm backend's JSFFI functionality; the

Adds `sortOn` to `Data.List.NonEmpty`, and adds
comments describing when to use it, compared to
`sortWith` or `sortBy . comparing`.
The aim is to smooth out the API between
`Data.List`, and `Data.List.NonEmpty`.
This change has been discussed in the
[clc issue](https://github.com/haskell/core-libraries-committee/issues/227).

GHC Proposal 448 introduces binders for invisible type arguments
(@a-binders) in various contexts. This patch implements @-binders
in lambda patterns and function equations:
{-# LANGUAGE TypeAbstractions #-}
id1 :: a -> a
id1 @t x = x :: t -- @t-binder on the LHS of a function equation
higherRank :: (forall a. (Num a, Bounded a) => a -> a) -> (Int8, Int16)
higherRank f = (f 42, f 42)
ex :: (Int8, Int16)
ex = higherRank (\ @a x -> maxBound @a - x )
-- @a-binder in a lambda pattern in an argument
-- to a higher-order function
Syntax
------
To represent those @-binders in the AST, the list of patterns in Match
now uses ArgPat instead of Pat:
data Match p body
= Match {
...
- m_pats :: [LPat p],
+ m_pats :: [LArgPat p],
...
}
+ data ArgPat pass
+ = VisPat (XVisPat pass) (LPat pass)
+ | InvisPat (XInvisPat pass) (HsTyPat (NoGhcTc pass))
+ | XArgPat !(XXArgPat pass)
The VisPat constructor represents patterns for visible arguments,
which include ordinary value-level arguments and required type arguments
(neither is prefixed with a @), while InvisPat represents invisible type
arguments (prefixed with a @).
Parser
------
In the grammar (Parser.y), the lambda and lambda-cases productions of
aexp non-terminal were updated to accept argpats instead of apats:
aexp : ...
- | '\\' apats '->' exp
+ | '\\' argpats '->' exp
...
- | '\\' 'lcases' altslist(apats)
+ | '\\' 'lcases' altslist(argpats)
...
+ argpat : apat
+ | PREFIX_AT atype
Function left-hand sides did not require any changes to the grammar, as
they were already parsed with productions capable of parsing @-binders.
Those binders were being rejected in post-processing (isFunLhs), and now
we accept them.
In Parser.PostProcess, patterns are constructed with the help of
PatBuilder, which is used as an intermediate data structure when
disambiguating between FunBind and PatBind. In this patch we define
ArgPatBuilder to accompany PatBuilder. ArgPatBuilder is a short-lived
data structure produced in isFunLhs and consumed in checkFunBind.
Renamer
-------
Renaming of @-binders builds upon prior work on type patterns,
implemented in 2afbddb0f24, which guarantees proper scoping and
shadowing behavior of bound type variables.
This patch merely defines rnLArgPatsAndThen to process a mix of visible
and invisible patterns:
+ rnLArgPatsAndThen :: NameMaker -> [LArgPat GhcPs] -> CpsRn [LArgPat GhcRn]
+ rnLArgPatsAndThen mk = mapM (wrapSrcSpanCps rnArgPatAndThen) where
+ rnArgPatAndThen (VisPat x p) = ... rnLPatAndThen ...
+ rnArgPatAndThen (InvisPat _ tp) = ... rnHsTyPat ...
Common logic between rnArgPats and rnPats is factored out into the
rn_pats_general helper.
Type checker
------------
Type-checking of @-binders builds upon prior work on lazy skolemisation,
implemented in f5d3e03c56f.
This patch extends tcMatchPats to handle @-binders. Now it takes and
returns a list of LArgPat rather than LPat:
tcMatchPats ::
...
- -> [LPat GhcRn]
+ -> [LArgPat GhcRn]
...
- -> TcM ([LPat GhcTc], a)
+ -> TcM ([LArgPat GhcTc], a)
Invisible binders in the Match are matched up with invisible (Specified)
foralls in the type. This is done with a new clause in the `loop` worker
of tcMatchPats:
loop :: [LArgPat GhcRn] -> [ExpPatType] -> TcM ([LArgPat GhcTc], a)
loop (L l apat : pats) (ExpForAllPatTy (Bndr tv vis) : pat_tys)
...
-- NEW CLAUSE:
| InvisPat _ tp <- apat, isSpecifiedForAllTyFlag vis
= ...
In addition to that, tcMatchPats no longer discards type patterns. This
is done by filterOutErasedPats in the desugarer instead.

We must generate the hsc2hs wrapper at bindist installation time since
it must contain `--lflag` and `--cflag` arguments which depend upon the
installation path.
The solution here is to substitute these variables in the configure
script (see mk/hsc2hs.in). This is then copied over a dummy wrapper in
the install rules.

Namespace specifiers were added to syntax of fixity signatures:
- sigdecl ::= infix prec ops | ...
+ sigdecl ::= infix prec namespace_spec ops | ...
To preserve namespace during renaming MiniFixityEnv type
now has separate FastStringEnv fields for names that should be
on the term level and for name that should be on the type level.
makeMiniFixityEnv function was changed to fill MiniFixityEnv in the right way:
- signatures without namespace specifiers fill both fields
- signatures with 'data' specifier fill data field only
- signatures with 'type' specifier fill type field only
Was added helper function lookupMiniFixityEnv that takes care about
looking for a name in an appropriate namespace.

This commit removes the unused HAVE_C11_ATOMICS macro. We used to have
a few places that have fallback paths when HAVE_C11_ATOMICS is not
defined, but that is completely redundant, since the
FP_CC_SUPPORTS__ATOMICS configure check will fail when the C compiler
doesn't support C11 style atomics. There are also many places (e.g. in
unreg backend, SMP.h, library cbits, etc) where we unconditionally use
C11 style atomics anyway which work in even CentOS 7 (gcc 4.8), the
oldest distro we test in our CI, so there's no value in keeping
HAVE_C11_ATOMICS.

Currently `ghc -M` fails to account for `.hs-boot` files correctly,
leading to issues with cross-package one-shot builds failing. This
currently manifests in `GHC.Exception` due to the boot file for
`GHC.Internal.Stack`. Work around this by adding an explicit `import`,
ensuring that `GHC.Internal.Stack` is built before `GHC.Exception`.

This commit passes -j to hadrian in the hadrian/hie-bios scripts. When
the user starts HLS in a fresh clone that has just been configured, it
takes quite a while for hie-bios to pick up the ghc flags and start
actual indexing, due to the fact that the hadrian build step defaulted
to -j1, so -j speeds things up and improve HLS user experience in GHC.
Also add -j flag to .ghcid to speed up ghcid, and sets the Windows
build root to .hie-bios which also works and unifies with other
platforms, the previous build root _hie-bios was missing from
.gitignore anyway.

This commit enables parallelism when the hadrian/ghci scripts are
called in CI. The time bottleneck is in the hadrian build step, but
previously the build step wasn't parallelized.

When calling as `cc`, GCC does not outputs lowercased "gcc" at least in 13.2.1 version here.
```
$ cc --version
cc (GCC) 13.2.1 20230801
...
```
This fails the check and outputs the confusing message: `configure: $CC is not gcc; assuming it's a reasonably new C compiler`
This patch makes it check for upper-cased "GCC" too so that it works correctly:
```
checking version of gcc... 13.2.1

Its payload was used only for a small optimization in genAlts,
avoiding a few assignments for programs of this form:
case NormalDataCon arg1 arg2 of x { NormalDataCon x1 x2 -> ... ; }
But when compiling with optimizations, this sort of code is
generally eliminated by case-of-known-constructor in Core-to-Core.
So it doesn't seem worth tracking and cleaning up again in StgToJS.

In nonmovingTidyWeaks we want to check if the key of a weak pointer
lives in the non-moving heap. We do this by checking the flags of the
block the key lives in. But we need to be careful with values that live
outside the Haskell heap, since they will lack a block descriptor and
looking for one may lead to a segfault. In this case we should just
accept that it isn't on the non-moving heap.

T23540 is fragile on 32-bit platforms. The root cause is usage of
`getEvidenceTreesAtPoint`, which internally relies on `Name`'s `Ord`
instance, which is indeterministic. The solution is adding a
deterministic `Ord` instance for `EvidenceInfo` and sorting the
evidence trees before pretty printing. Fixes #24449.

This implements Proposal 0475, introducing the `ListTuplePuns` extension
which is enabled by default.
Disabling this extension makes it invalid to refer to list, tuple and
sum type constructors by using built-in syntax like `[Int]`,
`(Int, Int)`, `(# Int#, Int# #)` or `(# Int | Int #)`.
Instead, this syntax exclusively denotes data constructors for use with
`DataKinds`.
The conventional way of referring to these data constructors by
prefixing them with a single quote (`'(Int, Int)`) is now a parser
error.
Tuple declarations have been moved to `GHC.Tuple.Prim` and the `Solo`
data constructor has been renamed to `MkSolo` (in a previous commit).
Unboxed tuples and sums now have real source declarations in `GHC.Types`.
Unit and solo types for tuples are now called `Unit`, `Unit#`, `Solo`
and `Solo#`.
Constraint tuples now have the unambiguous type constructors `CTuple<n>`
as well as `CUnit` and `CSolo`, defined in `GHC.Classes` like before.
A new parser construct has been added for the unboxed sum data
constructor declarations.
The type families `Tuple`, `Sum#` etc. that were intended to provide
nicer syntax have been omitted from this change set due to inference
problems, to be implemented at a later time.

cmmToRawCmmHook was added 4 years ago in
d561c8f6244f8280a2483e8753c38e39d34c1f01. Its only user is the
Asterius project, which has been archived and deprecated in favor of
the ghc wasm backend. This patch starts deprecating cmmToRawCmmHook by
placing a DEPRECATED pragma, and actual removal shall happen in a
future GHC major release if no issue to oppose the deprecation has
been raised in the meantime.

Fix a bug in the x86 ncg where results would be wrong when the desired output
register and one of the input registers were the same global.
Also adds a tiny optimization to make use of the memory addressing
support when convenient.
Fixes #24496

isCross() was a misnamed because it assumed that all cross targets would
provide a target wrapper, but the two most common cross targets
(javascript, wasm) don't need a target wrapper.
Therefore we rename this predicate to `needsTargetWrapper()` so
situations in the testsuite where we can check whether running
executables requires a target wrapper or not.
