JS: add simple optimizer
The simple optimizer reduces the size of the code generated by the
JavaScript backend without the complexity and performance penalty
of the optimizer in GHCJS.

Fix C output for modern C initiative
GCC 14 on aarch64 rejects the C code written by GHC with this kind of
error:
error: assignment to ‘ffi_arg’ {aka ‘long unsigned int’} from ‘HsPtr’ {aka ‘void *’} makes integer from pointer without a cast [-Wint-conversion]
68 | *(ffi_arg*)resp = cret;
| ^
Add the correct cast.

compiler: add SEQ_CST fence support
In addition to existing Acquire/Release fences, this commit adds
SEQ_CST fence support to GHC, allowing Cmm code to explicitly emit a
fence that enforces total memory ordering. The following logic is
added:
- The MO_SeqCstFence callish MachOp
- The %prim fence_seq_cst() Cmm syntax and the SEQ_CST_FENCE macro in Cmm.h
- MO_SeqCstFence lowering logic in every single GHC codegen backend

testsuite: fix hs_try_putmvar002 for targets without pthread.h
hs_try_putmvar002 includes pthread.h and doesn't work on targets
without this header (e.g. wasm32). It doesn't need to include this
header at all. This was previously unnoticed by wasm CI, though recent
toolchain upgrade brought in upstream changes that completely removes
pthread.h in the single-threaded wasm32-wasi sysroot, therefore we
need to handle that change.

Parser, renamer, type checker for @a-binders (#17594)
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.

hadrian: Generate HSC2HS_EXTRAS variable in bindist installation
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.
Fixes #24050.

Namespacing for fixity signatures (#14032)
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.

rts: remove unused HAVE_C11_ATOMICS macro
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.

hadrian/hie-bios: pass -j to hadrian
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 fails the check and outputs the confusing message: `configure: $CC is not gcc; assuming it's a reasonably new C compiler`

StgToJS: Simplify ExprInline constructor of ExprResult
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.

rts: avoid checking bdescr of value outside of Haskell heap
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.
Resolves #24492

testsuite: fix T23540 fragility on 32-bit platforms
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.

hadrian: Improve parallelism in binary-dist-dir rule
I noticed that the "docs" target was needed after the libraries and
executables were built. We can improve the parallelism by needing
everything at once so that documentation can be built immediately after
a library is built for example.

Introduce ListTuplePuns extension
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.
See the MR discussion for more info.

Improve error messages coming from non-linear patterns
This enriched the `CtOrigin` for non-linear patterns to include data
of the pattern that created the constraint (which can be quite useful
if it occurs nested in a pattern) as well as an explanation why the
pattern is non-restricted in (at least in some cases).

compiler: start deprecating cmmToRawCmmHook
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.
