This is the following find and replace:
- `rts/dist` -> `rts/dist-install` # for paths
- `rts_dist` -> `rts_dist-install` # for make rules and vars
- `,dist` -> `,dist-install` # for make, just in rts/ghc.mk`
Why do this? Does it matter when the RTS is just built once? The answer
is, yes, I think it does, because I want the distdir--stage
correspondence to be consistent.
In particular, for #17191 and continuing from
d5de970dafd5876ef30601697576167f56b9c132 I am going to make the headers
(`rts/includes`) increasingly the responsibility of the RTS (hence their
new location). However, those headers are current made for multiple
stages. This will probably become unnecessary as work on #17191
progresses and the compiler proper becomes more of a freestanding cabal
package (e.g. a library that can be downloaded from Hackage and built
without any autoconf). However, until that is finished, we have will
transitional period where the RTS and headers need to agree on dirs for
multiple stages.
I know the make build system is going away, but it's not going yet, so I
need to change it to unblock things :).

This drops allocateExec for darwin, and replaces it with
a alloc, write, mark executable strategy instead. This prevents
us from trying to allocate an executable range and then write to
it, which X^W will prohibit on darwin.
This will *only* work if we can use mmap.

Now that GHC 9.0.1 is released, it is time to drop support for bootstrapping
with GHC 8.8, as we only support building with the previous two major GHC
releases. As an added bonus, this allows us to remove several bits of CPP that
are either always true or no longer reachable.

This requires bumping the `exceptions` and `text` submodules to bring
in commits that bump their respective upper version bounds on
`template-haskell`.
Fixes #17645. Fixes #17696.
Note that the new `text` commit includes a fair number of additions
to the Haddocks in that library. As a result, Haddock has to do more
work during the `haddock.Cabal` test case, increasing the number of
allocations it requires. Therefore,

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.

- Cabal-2.2 uses SPDX license identifiers, so I had to update
`cabal-version: 2.1` packages `license: BSD3` to `license: BSD-3-Clause`
- `ghc-cabal` used old ReadP parsec, now it uses `parsec` too
- InstalledPackageInfo pretty-printing have changed a little,
fields with default values aren't printed. This can be changed in
`Cabal` still, but I haven't found problems with omitting them.
Note: `BSD-3-Clause` is parsed as "name = BSD, version = 3" by old
parser (because 3-Clause looks like version 3 with tag Clause).
If you see *"BSD-3" is not a valid license*, then something is using
old parser still.
Fixes #9885.

I originally introduced this hack 3 years ago in
b0379819e46796047c1574a6abccf186afd27afa, and finally we can
retire it because starting with GHC 8.0 (which is the minimum
required version to bootstrap GHC 8.4) these macros are generated
natively by GHC.

This patch removes dll-split from the code base, the reason is dll-split
no longer makes any sense. It was designed to split a dll in two, but we
now already have many more symbols than would fit inside two dlls. So we
need a third one. This means there's no point in having to maintain this
list as it'll never work anyway and the solution isn't scalable.

Cabal's parser has been rewritten in terms of Parsec (which is not
enabled yet in Cabal-2.0 by default, but can be enabled by a cabal
flag). The plan for Cabal is to drop support for the non-parsec parser,
so we need to prepare GHC to cope with new situation.
However, this means that lib:Cabal requires three new library
dependency submodules,
- parsec
- text
- mtl
What complicates matters is that we need to build `ghc-cabal` early on
during the bootstrap phase which currently needs to invoke `ghc --make`
directly. So these additional dependencies need to be integrated into
the monolithic `ghc --make` invocation which produces the `ghc-cabal`
executable.
Test Plan: `./validate --fast` passed

Summary:
This is a complete fix based off of
ed7af26606b3a605a4511065ca1a43b1c0f3b51d for handling
shadowing and out-of-order -package-db flags simultaneously.
The general strategy is we first put all databases together,
overriding packages as necessary. Once this is done, we successfully
prune out broken packages, including packages which depend on a package
whose ABI differs from the ABI we need.
Our check gracefully degrades in the absence of abi-depends, as
we only check deps which are recorded in abi-depends.
Contains time and Cabal submodule update.

Summary:
Build systems / package managers want to be able to control the file
layout of installed libraries. In general they may want/need to be able
to put the static libraries and dynamic libraries in different places.
The ghc-pkg library regisrtation needs to be able to handle this.
This is already possible in principle by listing both a static lib dir
and a dynamic lib dir in the library-dirs field (indeed some previous
versions of Cabal did this for shared libs on ELF platforms).
The downside of listing both dirs is twofold. There is a lack of
precision, if we're not careful with naming then we could end up
picking up the wrong library. The more immediate problem however is
that if we list both directories then both directories get included
into the ELF and Mach-O shared object runtime search paths. On ELF this
merely slows down loading of shared libs (affecting prog startup time).
On the latest OSX versions this provokes a much more serious problem:
that there is a rather low limit on the total size of the section
containing the runtime search path (and lib names and related) and thus
listing any unnecessary directories wastes the limited space.
So the solution in this patch is fairly straightforward: split the
static and dynamic library search paths in the ghc-pkg db and its use
within ghc. This is a traditional solution: pkg-config has the same
static / dynamic split (though it describes in in terms of private and
public, but it translates into different behaviour for static and
dynamic linking).
Indeed it would make perfect sense to also have a static/dynamic split
for the list of the libraries to use i.e. to have dynamic variants of
the hs-libraries and extra-libraries fields. These are not immediately
required so this patch does not add it, but it is a reasonable
direction to follow.
To handle compatibility, if the new dynamic-library-dirs field is not
specified then its value is taken from the library-dirs field.
Contains Cabal submodule update.
Test Plan:
Run ./validate
Get christiaanb and carter to test it on OSX Sierra, in combination
with Cabal/cabal-install changes to the default file layout for
libraries.
