When the users guide fails to build (as in #17346), a
`docs/users_guide/.log` file will be generated with contents that
look something like this:
```

The full traceback has been saved in /tmp/sphinx-err-rDF2LX.log, if you want to report the issue to the developers.
```
This definitely should not be checked in to version control, so let's
add this to `.gitignore`.

The generated headers are now generated per stage, which means we can
skip hacks like `ghc_boot_platform.h` and just have that be the stage 0
header as proper. In general, stages are to be embraced: freely generate
everything in each stage but then just build what you depend on, and
everything is symmetrical and efficient. Trying to avoid stages because
bootstrapping is a mind bender just creates tons of bespoke
mini-mind-benders that add up to something far crazier.
Hadrian was pretty close to this "stage-major" approach already, and so
was fairly easy to fix. Make needed more work, however: it did know
about stages so at least there was a scaffold, but few packages except
for the compiler cared, and the compiler used its own counting system.
That said, make and Hadrian now work more similarly, which is good for
the transition to Hadrian. The merits of embracing stage aside, the
change may be worthy for easing that transition alone.

As of commit d37d91e9a444a7822eef1558198d21511558515e, the GHC build
now autogenerates a `includes/dist/build/settings` file. To avoid
dirtying the current `git` status, this adds `includes/dist` to
`.gitignore`.

The splitter is an evil Perl script that processes assembler code.
Its job can be done better by the linker's --gc-sections flag. GHC
passes this flag to the linker whenever -split-sections is passed on
the command line.
This is based on @DemiMarie's D2768.

This adds trace messages that include the processes name and as such
make debugging and following the communication easier.
It also adds a note regarding the fwd*Call proxy-communication logic
between the proxy and the slave.
The proxy will now also poll for 60s to wait for the remote iserv
to come up. (Alternatively you can start the remote process
beforehand; and just have iserv-proxy connect to it)

Along the way, I discovered that `template-haskell.cabal` was
hard-coding the GHC version (in the form of its `ghc-boot-th` version
bounds), so I decided to make life a little simpler in the future by
generating `template-haskell.cabal` with autoconf.

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.

Summary:
My very last commit to D4904 removed -fobject-code. I should have tested this
more thoroughly, because it is required to do a fresh ghci load, as some code
uses unboxed tuples.
One of my motivations for doing this was that if you run the script without
passing -odir / -hidir, it would pollute the source tree with .hi and .o files.
This also appeared to break subsequent builds. I've made it much less likely
that this will happen by instead specifying -odir and -hidir within the ghci
script rather than on the commandline.
I plan to open a separate diff which adds a test that these scripts work.
Until this patch is merged, the workaround is to do `./utils/ghc-in-ghci/run.sh -fobject-code`

Summary:
Implement the "Embrace Type :: Type" GHC proposal,
.../ghc-proposals/blob/master/proposals/0020-no-type-in-type.rst
GHC 8.0 included a major change to GHC's type system: the Type :: Type
axiom. Though casual users were protected from this by hiding its
features behind the -XTypeInType extension, all programs written in GHC
8+ have the axiom behind the scenes. In order to preserve backward
compatibility, various legacy features were left unchanged. For example,
with -XDataKinds but not -XTypeInType, GADTs could not be used in types.
Now these restrictions are lifted and -XTypeInType becomes a redundant
flag that will be eventually deprecated.
* Incorporate the features currently in -XTypeInType into the
-XPolyKinds and -XDataKinds extensions.
* Introduce a new extension -XStarIsType to control how to parse * in
code and whether to print it in error messages.

This is done for consistency. We usually call the package file the same name the
folder has. The move into `utils` is done so that we can move the library into
`libraries/iserv` and the proxy into `utils/iserv-proxy` and then break the
`iserv.cabal` apart. This will make building the cross compiler with TH
simpler, because we can build the library and proxy as separate packages.

This pulls parts of Joachim Breitner's ghc-heap-view library inside GHC.
The bits added are the C hooks into the RTS and a basic Haskell wrapper
to these C hooks. The main reason for these to be added to GHC proper
is that the code needs to be kept in sync with the closure types
defined by the RTS. It is expected that the version of HeapView shipped
with GHC will always work with that version of GHC and that extra
functionality can be layered on top with a library like ghc-heap-view
distributed via Hackage.

Summary:
This shims out fopen and sopen so that they use modern APIs under the hood
along with namespaced paths.
This lifts the MAX_PATH restrictions from Haskell programs and makes the new
limit ~32k.
There are only some slight caveats that have been documented.
Some utilities have not been upgraded such as lndir, since all these things are
different cabal packages I have been forced to copy the source in different places
which is less than ideal. But it's the only way to keep sdist working.

Overlap with commit 2f463873, resulted in `hooks/LongGCSync.c`
missing from the `rts.cabal.in` file. As the `rts.cabal` file is only
used by hadrian, this did not trigger with the make base build

Summary:
This tool can be used to generate dll's for any list of object files
given to it. It will then repartition them automatically to fit within
a dll and generates as many dll's as needed to do this. Cyclic dependencies
between these generated dlls are handle automatically so there is no need
to tell it how to partition.
It is also a lot more general than `dll-split` as it is able to split any
package not just `libGHC`. It also uses a trick using GNU style import libraries
to hide the splitting from the rest of the pipeline. Which means come linking time
you don't need to know which dll contains what symbol or how many split dlls were
created.
The import libraries are by default created with libtool. However since libtool is BFD
based it is very slow. So if present and detected by configure the `genlib` tool
from the msys2 project is used. This makes a difference of about ~45 minutes when compiling.
To install `genlib` run `pacman -Sy mingw-w64-$(uname -m)-tools-git`.

This removes all dependencies the users guide had on `mkUserGuidePart`.
The generation of the flag reference table and the various pieces of the
man page is now entirely contained within the Spinx extension
`flags.py`. You can see the man page generation on the orphan page
https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/ghc.html
The extension works by collecting all of the meta-data attached to the
`ghc-flag` directives and then formatting and displaying it at
`flag-print` directives. There is a single printing directive that can
be customized with two options, what format to display (table, list, or
block of flags) and an optional category to limit the output to
(verbosity, warnings, codegen, etc.).
New display formats can be added by creating a function
`generate_flag_xxx` (where `xxx` is a description of the format) which
takes a list of flags and a category and returns a new `xxx`. Then just
add a reference in the dispatch table `handlers`. That display can now
be run by passing `:type: xxx` to the `flag-print` directive.
`flags.py` contains two maps of settings that can be adjusted. The first
is a canonical list of flag categories, and the second sets default
categories for files.
The only functionality that Sphinx could not replace was the
`what_glasgow_exts_does.gen.rst` file. `mkUserGuidePart` actually just
reads the list of flags from `compiler/main/DynFlags.hs` which Sphinx
cannot do. As the flag is deprecated, I added the list as a static file
which can be updated manually.
Additionally, this patch updates every single documented flag with the
data from `mkUserGuidePart` to generate the reference table.
Fixes #11654 and, incidentally, #12155.

The `GHC.LanguageExtensions.Type` module is also re-exported by

Makes the needed changes to make RemoteGHCi work on Windows.
The approach passes OS Handles areound instead of the Posix Fd
as on Linux.
The reason is that I could not find any real documentation about
the behaviour of Windows w.r.t inheritance and Posix FDs.
The implementation with Fd did not seem to be able to find the Fd
in the child process. Instead I'm using the much better documented
approach of passing inheriting handles.
This requires a small modification to the `process` library.

In order to simplify the task, the version munging logic has
been radically simplified:
Previously, in cases where the version contained dates as version components,
the build-system would munge the version of the stage1 ghc package before
registering the `ghc` package.
However, this hack was already questionable at the time of its introduction
(c.f. 7b45c46cbabe1288ea87bd9b94c57e010ed17e60).
Simplifying the build-systems by avoiding such hacks may also help the
shaking-up-ghc effort.
So now we simply munge directly via the `.cabal` files, which gives a simpler
picture, as now every stage is munged the same. Munging is only active when
the first patch-level version component is a date. So stable snapshots and release
candidates are unaffacted (as those have the date in the second patch-level
version component)

Summary:
(Apologies for the size of this patch, I couldn't make a smaller one
that was validate-clean and also made sense independently)
(Some of this code is derived from GHCJS.)
This commit adds support for running interpreted code (for GHCi and
TemplateHaskell) in a separate process. The functionality is
experimental, so for now it is off by default and enabled by the flag
-fexternal-interpreter.
Reaosns we want this:
* compiling Template Haskell code with -prof does not require
building the code without -prof first
* when GHC itself is profiled, it can interpret unprofiled code, and
the same applies to dynamic linking. We would no longer need to
force -dynamic-too with TemplateHaskell, and we can load ordinary
objects into a dynamically-linked GHCi (and vice versa).
* An unprofiled GHCi can load and run profiled code, which means it
can use the stack-trace functionality provided by profiling without
taking the performance hit on the compiler that profiling would
entail.
Amongst other things; see
https://ghc.haskell.org/trac/ghc/wiki/RemoteGHCi for more details.
Notes on the implementation are in Note [Remote GHCi] in the new
module compiler/ghci/GHCi.hs. It probably needs more documenting,
feel free to suggest things I could elaborate on.
Things that are not currently implemented for -fexternal-interpreter:
* The GHCi debugger
* :set prog, :set args in GHCi
* `recover` in Template Haskell
* Redirecting stdin/stdout for the external process
These are all doable, I just wanted to get to a working validate-clean
patch first.
I also haven't done any benchmarking yet. I expect there to be slight hit
to link times for byte code and some penalty due to having to
serialize/deserialize TH syntax, but I don't expect it to be a serious
problem. There's also lots of low-hanging fruit in the byte code
generator/linker that we could exploit to speed things up.
Test Plan:
* validate
* I've run parts of the test suite with
EXTRA_HC_OPTS=-fexternal-interpreter, notably tests/ghci and tests/th.
There are a few failures due to the things not currently implemented
(see above).

We can't just solve CallStack constraints indiscriminately when they
occur in the RHS of a let-binder. The top-level given CallStack (if
any) will not be in scope, so I've re-worked the CallStack solver as
follows:
1. CallStacks are treated like regular IPs unless one of the following
two rules apply.
2. In a function call, we push the call-site onto a NEW wanted
CallStack, which GHC will solve as a regular IP (either directly from a
given, or by quantifying over it in a local let).
3. If, after the constraint solver is done, any wanted CallStacks
remain, we default them to the empty CallStack. This rule exists mainly
to clean up after rule 2 in a top-level binder with no given CallStack.
In rule (2) we have to be careful to emit the new wanted with an
IPOccOrigin instead of an OccurrenceOf origin, so rule (2) doesn't fire
again. This is a bit shady but I've updated the Note to explain the
trick.

With the move to RST-based documentation, there is no need to ignore XML files
in the source tree anymore.

Summary:
This reverts commit aecf4a5f96d0d3ffcf4cb2c67a20a610d7c64486.
It turns out the Simons are relying on 'mk/are-validating.mk', see
D1307.
The workflow they are using is:
* run ./validate
* find a bug in the compiler
* try to fix the bug, running 'make 1' (or 'make 2') repeatedly. Because
of 'mk/are-validating.mk', this uses the same build settings as validate.
* continue ./validate (--no-clean)
I suggested two alternatives:
A. run 'make 1 Validating=YES' instead of 'make 1'
Problem: when running `./validate --fast` or `./validate --hpc`
instead of a normal `./validate`, validate sets ValidateSpeed and
ValdateHpc in mk/are-validating.mk. You would for example have to run
'make 1 Validating=YES ValidateSpeed=FAST' instead of 'make 1' to get the
same build settings as `./validate --fast`, which is entirely too long and
error prone.
B. uncomment `#BuildFlavour=validate` in mk/build.mk, and include
'mk/validate.mk'.
Problems:
* any other settings you have in build.mk will also get used.
* the distinction between 'mk/validate.mk' and 'mk/build.mk' becomes less
clear.
* it is easy to forget to include 'mk/validate.mk'.
* the build system again doesn't have access to the ValidateSpeed and
ValdateHpc settings set by validate.
Neither of these two options is entirely satisfactory.
