The patch from https://phabricator.haskell.org/D4865 introduces
go _ (HsParTy _ (dL->L l (HsStarTy _ isUni))) acc ann fix
= do { warnStarBndr l
; let name = mkOccName tcClsName (if isUni then "★" else "*")
; return (cL l (Unqual name), acc, fix, ann) }
which discards the parens annotations belonging to the HsParTy.

The parens around the kinded tyvars should be attached to the class
declaration as a whole, they are attached to the tyvar instead,
outside the span.
An annotation must always be within or after the span it is contained
in.

For an API annotation to be useful, it must not occur before the span
it is enclosed in.
So, for check-api-annotation output, a line such as
((Test16212.hs:3:22-36,AnnOpenP), [Test16212.hs:3:21]),
should be flagged as an error, as the AnnOpenP location of 3:21
precedes its enclosing span of 3:22-26.
This patch does this.

This also requires adapting `ghc-pkg` to use the new Cabal parsing API
as the old ReadP-based one has finally been evicted for good.

Summary:
This patch implements visible kind application (GHC Proposal 15/#12045), as well as #15360 and #15362.
It also refactors unnamed wildcard handling, and requires that type equations in type families in Template Haskell be
written with full type on lhs. PartialTypeSignatures are on and warnings are off automatically with visible kind
application, just like in term-level.
There are a few remaining issues with this patch, as documented in
ticket #16082.
Includes a submodule update for Haddock.

be using x86_64-unknown-freebsd. Not knowing which is correct I've left

Summary:
Currently, `ghc-in-ghci` is hard-coded to only support
the installation path of the `make`-based build system. There isn't
a fundamental reason why this must be the case, however—it's just a
matter of communicating which directories to look into.
For the time being, I've hacked `utils/ghc-in-ghci/run.sh` to just
check the default Hadrian installation path in addition to the `make`
one. Disclaimer: I'm not well-versed in `bash`-fu, so it's possible
that there is a better way to accomplish what I'm setting out to do.
Suggestions welcome.

Summary:
Currently, the version numbers for `libiserv`, `iserv`, and
`iserv-proxy` are hard-coded directly into their `.cabal` files.
These are easy to forget to update, and in fact, this has already
happened once (see #15866). Let's use `autoconf` to do this for us
so that it is not forgotten in the future.

This patch removes the ping-pong style from HsPat (only, for now),
using the plan laid out at
https://ghc.haskell.org/trac/ghc/wiki/ImplementingTreesThatGrow/HandlingSourceLocations (solution
A).
- the class `HasSrcSpan`, and its functions (e.g., `cL` and `dL`), are introduced
- some instances of `HasSrcSpan` are introduced
- some constructors `L` are replaced with `cL`
- some patterns `L` are replaced with `dL->L` view pattern
- some type annotation are necessarily updated (e.g., `Pat p` --> `Pat (GhcPass p)`)

This patch fixes a fairly long-standing bug (dating back to 2015) in
RdrName.bestImport, namely
commit 9376249b6b78610db055a10d05f6592d6bbbea2f
Author: Simon Peyton Jones <simonpj@microsoft.com>
Date: Wed Oct 28 17:16:55 2015 +0000
Fix unused-import stuff in a better way
In that patch got the sense of the comparison back to front, and
thereby failed to implement the unused-import rules described in
Note [Choosing the best import declaration] in RdrName
This led to Trac #13064 and #15393
Fixing this bug revealed a bunch of unused imports in libraries;
the ones in the GHC repo are part of this commit.
The two important changes are
* Fix the bug in bestImport
* Modified the rules by adding (a) in
Note [Choosing the best import declaration] in RdrName
Reason: the previosu rules made Trac #5211 go bad again. And
the new rule (a) makes sense to me.
In unravalling this I also ended up doing a few other things
* Refactor RnNames.ImportDeclUsage to use a [GlobalRdrElt] for the
things that are used, rather than [AvailInfo]. This is simpler
and more direct.
* Rename greParentName to greParent_maybe, to follow GHC
naming conventions
* Delete dead code RdrName.greUsedRdrName
Bumps a few submodules.

The format of hp file didn't allow double quotes inside strings, and
under prof build, we include args in JOB, which may have double quotes.
When this happens, the error message is confusing to the user. This can
also happen under normal build if the executable name contains double
quite, which is unlikely though.
We fix this issue by introducing escaping for double quotes inside a
string by repeating it twice.
We also fix a buffer overflow bug when the length of the string happen
to be multiple of 5000.
Test Plan:
new tests, which used to fail with error message:
```
hp2ps: "T15904".hp, line 2: integer must follow identifier
```
use new ghc and hp2ps to profile a simple program.

This is the first step of implementing:
https://github.com/ghc-proposals/ghc-proposals/pull/74
The main highlights/changes:
primops.txt.pp gets two new sections for two new primitive types for
signed and unsigned 8-bit integers (Int8# and Word8 respectively) along
with basic arithmetic and comparison operations. PrimRep/RuntimeRep get
two new constructors for them. All of the primops translate into the
existing MachOPs.
For CmmCalls the codegen will now zero-extend the values at call
site (so that they can be moved to the right register) and then truncate
them back their original width.
x86 native codegen needed some updates, since it wasn't able to deal
with the new widths, but all the changes are quite localized. LLVM
backend seems to just work.
This is the second attempt at merging this, after the first attempt in
D4475 had to be backed out due to regressions on i386.
Bumps binary submodule.

Summary:
This simply makes explicit what is already the case. Due to special
treatment in the parser, `->` has the lowest fixity. This patch propagates
that information to:
* GHCi, where `:info ->` now return the right fixity
* TH, where `reifyFixity` returns the right fixity
* the generated sources for `GHC.Prim`

Summary:
* Extended `genprimcode` to generate Haddock-compatible deprecations,
as well as displaying information about which functions are LLVM-only
and which functions can fail with an unchecked exception.
* Ported existing deprecations to the new format, and also added a
deprecation on `par#` (see Trac #15227).
* Emit an error on fixity/deprecation of builtins, unless we are
processing the module in which that name is defined (see Trac #15233).
That means the following is no longer accepted (outside of `GHC.Types`):
```
infixr 7 :
{-# DEPRECATED (:) "cons is deprecated" #-}
```
* Generate `data (->) a b` with docs and fixity in `GHC.Prim`. This
means: GHC can now parse `data (->) a b` and `infixr 0 ->` (only in
`GHC.Prim`) and `genprimcode` can digest `primtype (->) a b` (See Trac
#4861)
as well as some misc fixes along the way.

Summary:
The new filesystem code accidentally asks for write attributes
permissions when doing read-only access.
I believe this is what's causing the GHC 8.6.1 tarballs to fail
when installed to a privileged location.
I haven't been able to reproduce the issue yet, but this permission
bit is wrong anyway.
Test Plan: I'm still trying to workout how to test that this works,
changing the permissions on the folder doesn't seem to reproduce
the error on a tarball I made from before the change.

This patch corresponds to #15497.
According to https://ghc.haskell.org/trac/ghc/wiki/DependentHaskell/Phase2,
we would like to have coercion quantifications back. This will
allow us to migrate (~#) to be homogeneous, instead of its current
heterogeneous definition. This patch is (lots of) plumbing only. There
should be no user-visible effects.
An overview of changes:
- Both `ForAllTy` and `ForAllCo` can quantify over coercion variables,
but only in *Core*. All relevant functions are updated accordingly.
- Small changes that should be irrelevant to the main task:
1. removed dead code `mkTransAppCo` in Coercion
2. removed out-dated Note Computing a coercion kind and
roles in Coercion
3. Added `Eq4` in Note Respecting definitional equality in
TyCoRep, and updated `mkCastTy` accordingly.
4. Various updates and corrections of notes and typos.
- Haddock submodule needs to be changed too.

Long ago, the stable name table and stable pointer tables were one.
Now, they are separate, and have significantly different
implementations. I believe the time has come to finish the split
that began in #7674.
* Divide `rts/Stable` into `rts/StableName` and `rts/StablePtr`.
* Give each table its own mutex.
* Add FFI functions `hs_lock_stable_ptr_table` and
`hs_unlock_stable_ptr_table` and document them.
These are intended to replace the previously undocumented
`hs_lock_stable_tables` and `hs_lock_stable_tables`,
which are now documented as deprecated synonyms.
* Make `eqStableName#` use pointer equality instead of unnecessarily
comparing stable name table indices.

Summary:
This completes the work started in D4227 by using just 'getExecutablePath'
in ghc and ghc-pkg when building with base >= 4.11.0.
On the long term, we will be able to simply kill the existing code that
follows (or not) symlinks and just get this behaviour for free from
getExecutable. For now we however have to require base >= 4.11.0 to be able
to just use getExecutablePath under Windows, and use the current code when
building with an older base.
Original code by @alpmestan commandeering since patch has been stale
and bug remains open.

Calculating which modules to load based on the InteractiveContext means
maintaining a potentially very large GblRdrEnv.
In Haddock's case, it is much cheaper (from a memory perspective) to
just keep track of which modules interfaces we want loaded then hand
these off explicitly to 'getNameToInstancesIndex'.
Bumps haddock submodule.

When parsing a nested comment or nested doc comment in the lexer, if we
see a line starting with '#' we attempt to parse a #line pragma. This
fixes how ghc handles output of the C preproccesor (-cpp flag) when the
original source has C comments or pragmas inside haskell comments.
Updates haddock submodule.

This allows you to use the ghc-in-ghci script in Make even if you
haven't built stage2, and also with Hadrian. Because of the way -I
works, it will prefer Make/stage2.
