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.

emcc would sometime output messages like:
cache:INFO: generating system asset: symbol_lists/424b44514e43d789148e69e4e7d1c7fdc0350b79.json... (this will be cached in "/emsdk/upstream/emscripten/cache/symbol_lists/424b44514e43d789148e69e4e7d1c7fdc0350b79.json" for subsequent builds)
cache:INFO: - ok
Cf https://github.com/emscripten-core/emscripten/issues/18607
This breaks our tests matching the stderr output. We avoid this by setting EMCC_LOGGING=0

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.

- 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

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

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.
Fixes #24050.

Previously we were trying to use the FP_CC_SUPPORTS_TARGET with 4
arguments, when it only takes 3 arguments. Instead we need to use the
`FP_PROG_CC_LINKER_TARGET` function in order to set the linker flags.

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.
Updates haddock submodule.

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.

The `ghc-toolchain` overhaul will eventually replace all this stuff with
something much more cleaned up, but I think it is still worth making
this sort of cleanup in the meantime so other untanglings and dead code
cleaning can procede.
I was able to delete a fair amount of dead code doing this too.
