GHC Proposal #425 "Invisible binders in type declarations" forbids
implicit quantification of type variables that occur free on the
right-hand side of a type synonym but are not mentioned on the left-hand side.
The users are expected to rewrite this using invisible binders:
type T1 :: forall a . Maybe a
type T1 = 'Nothing :: Maybe a -- old
type T1 @a = 'Nothing :: Maybe a -- new
Since the @k-binders are a new feature, we need to wait for three releases
before we require the use of the new syntax. In the meantime, we ought to
provide users with a new warning, -Wimplicit-rhs-quantification, that would
detect when such implicit quantification takes place, and include it in -Wcompat.

Prior to this change, `can_eq_nc` checked the visibility of the
outermost layer of foralls:
forall a. forall b. forall c. phi1
forall x. forall y. forall z. phi2
^^
up to here
Then it delegated the rest of the work to `can_eq_nc_forall`, which
split off all foralls:
forall a. forall b. forall c. phi1
forall x. forall y. forall z. phi2
^^
up to here
This meant that some visibility flags were completely ignored.
We fix this oversight by moving the check to `can_eq_nc_forall`.

Blocking IO used uninterruptibleMask which should make any thread
blocked on IO unreachable by async exceptions (such as those from
timeout). This changes it to a regular mask.
It's important to note that the nodejs runtime does not actually
interrupt the blocking IO when the Haskell thread receives an
async exception, and that file positions may be updated and buffers
may be written after the Haskell thread has already resumed.
Any file descriptor affected by an async exception interruption
should therefore be used with caution.

The Haskell runtime used to install a 'readable' handler on stdin
at startup in nodejs. This would cause the nodejs system to start
buffering the stream, causing data loss if the stdin file
descriptor is passed to another process.
This change delays installation of the 'readable' handler until
the first read of stdin by Haskell code.

This patch modifies the renamer to respect ScopedTypeVariables in kind
signatures. This means that kind variables bound by the outermost
`forall` now scope over the type:
type F = '[Right @a @() () :: forall a. Either a ()]
-- ^^^^^^^^^^^^^^^ ^^^
-- in scope here bound here
However, any use of such variables is a type error, because we don't
have type-level lambdas to bind them in Core. This is described in the
new Note [Type variable scoping errors during type check] in GHC.Tc.Types.

GHC Proposal #425 "Invisible binders in type declarations" restricts the
scope of type and data family instances as follows:
In type family and data family instances, require that every variable
mentioned on the RHS must also occur on the LHS.
For example, here are three equivalent type instance definitions accepted before this patch:
type family F1 a :: k
type instance F1 Int = Any :: j -> j
type family F2 a :: k
type instance F2 @(j -> j) Int = Any :: j -> j
type family F3 a :: k
type instance forall j. F3 Int = Any :: j -> j
- In F1, j is implicitly quantified and it occurs only on the RHS;
- In F2, j is implicitly quantified and it occurs both on the LHS and the RHS;
- In F3, j is explicitly quantified.
Now F1 is rejected with an out-of-scope error, while F2 and F3 continue to be accepted.

IPE data resulting from the `-finfo-table-map` flag may now be
compressed by configuring the GHC build with the
`--enable-ipe-data-compression` flag. This results in about a 20%
reduction in the size of IPE-enabled build results.
The compression library, zstd, may optionally be statically linked by
configuring with the `--enabled-static-libzstd` flag (on non-darwin
platforms)
libzstd version 1.4.0 or greater is required.

This prepares for having linear let expressions in the frontend.
When desugaring lets, SPECIALISE statements create more copies of a
let binding. Because of the rewrite rules attached to the bindings,
there are dependencies between the generated binds.
Before this commit, we simply wrapped all these in a mutually
recursive let block, and left it to the simplified to sort it out.
With this commit: we are careful to generate the bindings in
dependency order, so that we can wrap them in consecutive lets (if the
source is non-recursive).

Previously `shutdown_handler` would call `stg_exit` if the scheduler was
Oalready found to be in `SCHED_INTERRUPTING` state (or higher). However,
`stg_exit` is not signal-safe as it calls `exit` (which calls `atexit`
handlers). The only safe thing to do in this situation is to call
`_exit`, which terminates with minimal cleanup.

This requires changing the recomp007 test because now cabal passes
`this-unit-id` to executable components, and that unit-id contains a
hash which includes the ABI of the dependencies. Therefore changing the
dependencies means that -this-unit-id changes and recompilation is
triggered.
The spririt of the test is to test GHC's recompilation logic assuming
that `-this-unit-id` is constant, so we explicitly pass `-ipid` to
`./configure` rather than letting `Cabal` work it out.

Previously the `+werror` transformer would only pass `-Werror` to GHC,
which does not ensure that the same is passed to the C compiler when
building the RTS. Arguably this is itself a bug but for now we will just
work around this by passing `-optc-Werror` to GHC.
I tried to enable `-Werror` in all C compilations but the boot libraries
are something of a portability nightmare.

- Do not include `mi_globals` in the `NoBackend` backend. It was only included
for Haddock, but Haddock does not actually need it. This causes a 200MB
reduction in max residency when generating haddocks on the Agda codebase
(roughly 1GB to 800MB).

This is an implementation of the deprecated exports proposal #134.
The proposal introduces an ability to introduce warnings to exports.
This allows for deprecating a name only when it is exported from a specific
module, rather than always depreacting its usage. In this example:
module A ({-# DEPRECATED "do not use" #-} x) where
x = undefined
---
module B where
import A(x)
`x` will emit a warning when it is explicitly imported.
Like the declaration warnings, export warnings are first accumulated within
the `Warnings` struct, then passed into the ModIface, from which they are
then looked up and warned about in the importing module in the `lookup_ie`
helpers of the `filterImports` function (for the explicitly imported names)
and in the `addUsedGRE(s)` functions where they warn about regular usages
of the imported name.
In terms of the AST information, the custom warning is stored in the
extension field of the variants of the `IE` type (see Trees that Grow for
more information).
The commit includes a bump to the haddock submodule added in MR #28

Bytecode instructions like PUSH_L (push a local variable) contain
an operand that refers to the stack slot. Before this patch, the
operand type was SmallOp (Word16), limiting the maximum stack
offset to 65535 words. This could cause compiler panics in some
cases (See #22888).
This patch changes the operand type for stack offsets from
SmallOp to Op, removing the stack offset limit.

Tracking ticket: #23394
MR: !10448
* Add constructor `IfaceBreakpoint` to `IfaceTickish`
* Store breakpoint data in interface files
* Store `BreakArray` for the breakpoint's module, not the current module, in BCOs
* Store module name in BCOs instead of `Unique`, since the `Unique` from an `Iface` doesn't match the modules in GHCi's
state
* Allocate module name in `ModBreaks`, like `BreakArray`
* Lookup breakpoint by module name in GHCi
* Skip creating breakpoint instructions when no `ModBreaks` are available, rather than injecting `ModBreaks` in the
linker when breakpoints are enabled, and panicking when `ModBreaks` is missing

Arity inference in type declarations was introduced
as a workaround for the lack of @k-binders.
They were added in 4aea0a72040, so I simplified all
of this by simply removing arity inference altogether.

GHC has no direct dependence on the linker. Rather, we depend upon the C
compiler for linking and an object-merging program (which is typically
`ld`) for production of GHCi objects and merging of C stubs into final
object files.
Despite this, for historical reasons we still recorded information about
the linker into `settings`. Remove these entries from `settings`,
`hadrian/cfg/system.config`, as well as the `configure` logic
responsible for this information.
Closes #23566.

There is a distinction to be made between the Haskell Preprocessor and
the C preprocessor. The former is used to preprocess Haskell files,
while the latter is used in C preprocessing such as Cmm files.
In practice, they are both the same program (usually the C compiler) but
invoked with different flags.
Previously we would, at configure time, configure the haskell
preprocessor and save the configuration in the settings file, but,
instead of doing the same for CPP, we had hardcoded in GHC that the CPP
program was either `cc -E` or `cpp`.
This commit fixes that asymmetry by also configuring CPP at configure
time, and tries to make more explicit the difference between HsCpp and
Cpp (see Note [Preprocessing invocations]).
Note that we don't use the standard CPP and CPPFLAGS to configure Cpp,
but instead use the non-standard --with-cpp and --with-cpp-flags.
The reason is that autoconf sets CPP to "$CC -E", whereas we expect the
CPP command to be configured as a standalone executable rather than a
command. These are symmetrical with --with-hs-cpp and
--with-hs-cpp-flags.
Cleanup: Hadrian no longer needs to pass the CPP configuration for CPP
to be C99 compatible through -optP, since we now configure that
into settings.
Closes #23422

Hadrian's `topDirectory` is intended to provide an absolute path to the
root of the GHC tree. However, if the tree is reached via a symlink this
One question here is whether the `canonicalizePath` call is expensive
enough to warrant caching. In a quick microbenchmark I observed that
`canonicalizePath "."` takes around 10us per call; this seems
sufficiently low not to worry.
Alternatively, another approach here would have been to rather move the
canonicalization into `m4/fp_find_root.m4`. This would have avoided
repeated canonicalization but sadly path canonicalization is a hard
problem in POSIX shell.
Addresses #22451.

The `'[]` case in `tc_infer_hs_type` is smart enough to handle arity-0 uses of
`'[]` (see the newly added `T23543` test case for an example), but the `'[]`
case in `tc_hs_type` was not. We fix this by changing the `tc_hs_type` case to
invoke `tc_infer_hs_type`, as prescribed in `Note [Future-proofing the type
checker]`.
There are some benign changes to test cases' expected output due to the new
code path using `forall a. [a]` as the kind of `'[]` rather than `[k]`.
Fixes #23543.

The previous configuration script to test whether Ld supported response
files was
* Incorrect (see #23542)
* Used, in practice, to check if the *merge objects tool* supported
response files.
This commit modifies the macro to run the merge objects tool (rather
than Ld), using a response file, and checking the result with $NM

Polymorphic specialisation has led to a number of hard to diagnose
incorrect runtime result bugs (see #23469, #23109, #21229, #23445) so
this commit introduces a flag `-fpolymorhphic-specialisation` which
allows users to turn on this experimental optimisation if they are
willing to buy into things going very wrong.

We used to choose flags to pass to the toolchain at runtime based on the
platform running GHC, and in this commit we drop all of those runtime
linker checks
Ultimately, this represents a change in policy: We no longer adapt at
runtime to the toolchain being used, but rather make final decisions
about the toolchain used at /configure time/
(we have deleted Note [Run-time linker info] altogether!).
This works towards the goal of having all toolchain configuration logic
living in the same place, which facilities the work towards a
runtime-retargetable GHC (see #19877).
As of this commit, the runtime linker/compiler logic was moved to
autoconf, but soon it, and the rest of the existing toolchain
configuration logic, will live in the standalone ghc-toolchain program
(see !9263)
In particular, what used to be done at runtime is now as follows:
* The flags -Wl,--no-as-needed for needed shared libs are configured
into settings
* The flag -fstack-check is configured into settings
* The check for broken tables-next-to-code was outdated
* We use the configured c compiler by default as the assembler program
* We drop `asmOpts` because we already configure -Qunused-arguments flag
into settings (see !10589)
Fixes #23562

The libffi shipped with Apple's XCode toolchain does not contain a
definition of the FFI_GO_CLOSURES macro, despite containing references
to said macro. Work around this by defining the macro, following the
model of a similar workaround in OpenJDK [1].
