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.

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.

Here we extend the parser and AST to preserve docstrings following

export items. We then extend Haddock to parse `@since` annotations in

such docstrings, allowing changes in export structure to be properly

documented.

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.

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.

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.

Updates the submodule utils/haddock.

Updates the cabal submodule due to new language extension.

        haddock.base

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.

1. We were using the package id rather than the package name for the

   package links. This is fixed by now allowing the template to mention

   %pkg% or %pkgid% and substituing both appropiatly.

2. The `--haddock-base-url` flag is renamed to `--haddock-for-hackage`

   as the new base link works on a local or remote hackage server.

3. The "src" path including too much stuff, so cross-package source

   links were broken as the template was getting double expanded.

1. Make GHC.Core.Opt.SetLevels.lvlMFE behave better when there are

   many free variables.  See Note [Large free-variable sets].

2. Make GHC.Core.Opt.Arity.floatIn a bit lazier in its Cost argument.

   This benefits the common case where the ArityType turns out to

   be nullary. See Note [Care with nested expressions]

3. Make GHC.CoreToStg.Prep.cpeArg behave for deeply-nested

   expressions.  See Note [Eta expansion of arguments in CorePrep]

   wrinkle (EA2).

Compile times go down by up to 4.5%, and much more in artificial

cases. (Geo mean of compiler/perf changes is -0.4%.)

Here we introduce the `Backtraces` type and associated machinery for

attaching these via `ExceptionContext`. These has a few compile-time

regressions (`T15703` and `T9872d`) due to the additional dependencies

in the exception machinery.

As well, there is a surprisingly large regression in the

`size_hello_artifact` test. This appears to be due to various `Integer` and

`Read` bits now being reachable at link-time. I believe it should be

As noted by #24344, `strerror` is not necessarily thread-safe.

Thankfully, POSIX.1-2001 has long offered `strerror_r`, which is

safe to use.

Fixes #24344.
