Here we at long last remove the `make`-based build system, it having
been replaced with the Shake-based Hadrian build system. Users are
encouraged to refer to the documentation in `hadrian/doc` and this [1]
blog post for details on using Hadrian.

Closes #17527.

This is an improvement to HPC authored by Richard Wallace
(https://github.com/purefn) and myself. I have received permission from
him to attempt to upstream it. This improvement was originally
implemented as a patch to HPC via input-output-hk/haskell.nix:
https://github.com/input-output-hk/haskell.nix/pull/1464



Paraphrasing Richard, HPC currently requires all inputs as command line arguments.
With large projects this can result in an argument list too long error.
I have only seen this error in Nix, but I assume it can occur is a plain Unix environment.

This MR adds the standard response file syntax support to HPC. For
example you can now pass a file to the command line which contains the
arguments.

```
hpc @response_file_1 @response_file_2 ...

The contents of a Response File must have this format:
COMMAND ...

example:
report my_library.tix --include=ModuleA --include=ModuleB
```

Updates hpc submodule

Fixes #22050

Matthew Pickering authored 3 years ago and Marge Bot committed 3 years ago

This fixes two bugs which were adding dependencies on alex/happy when
building from a source dist.

* When we try to pass `--with-alex` and `--with-happy` to cabal when
  configuring but the builders are not set. This is fixed by making them
  optional.
* When we configure, cabal requires alex/happy because of the
  build-tool-depends fields. These are now made optional with a cabal
  flag (build-tool-depends) for compiler/hpc-bin/genprimopcode.

Fixes #21627

Zubin authored 3 years ago and Matthew Pickering committed 3 years ago

This patch allows ghc and its dependencies to be built using a normal
invocation of cabal-install. Each componenent which relied on generated
files or additional configuration now has a Setup.hs file.

There are also various fixes to the cabal files to satisfy
cabal-install.

There is a new hadrian command which will build a stage2 compiler and
then a stage3 compiler by using cabal.

```
./hadrian/build build-cabal
```

There is also a new CI job which tests running this command.

For the 9.4 release we will upload all the dependent executables to
hackage and then end users will be free to build GHC and GHC executables
via cabal.

There are still some unresolved questions about how to ensure soundness
when loading plugins into a reinstalled GHC (#20742) which will be
tighted up in due course.

Fixes #19896

* Make sure files are being read/written in UTF-8. Set encoding while writing
  HTML output. Also set encoding while writing and reading .tix files although
  we don't yet have a ticket complaining that this poses problems.
* Set encoding in html header to utf8
* Upgrade to new version of 'hpc' library and reuse `readFileUtf8`
  and `writeFileUtf8` functions
* Update git submodule for `hpc`
* Bump up `hpc` executable version

Updates hpc submodule.

Updates a number of submodules.

This fixes some hpc tests on Windows. Update submodule hpc.

And remove unused imports and language pragmas.

I checked that the minimum Happy and Alex version requirements, as
listed in aclocal.m4, don't have to change. Before building ghc, I ran:
  - cabal install happy==1.19.4 --with-ghc=ghc-7.8.4
  - cabal install alex==3.1.0 --with-ghc=ghc-7.6.3

Summary:
BAD: "." ++ "/" ++ "/absolute/path" == ".//absolute/path"
GOOD: "." </> "/absolute/path" == "/absolute path"

Also replace `++ ".ext"` with `<.> "ext"`. Although it doesn't fix any
bugs in this instance, it might in some other. As a general rule it's
better not to use (++) on FilePaths.

Summary:
All commands now have `--verbosity` flag, so one can configure
cabal package with `--hpc-options="--verbosity=0"`.

Right now it is used only in `hpc markup` to supress unnecessary

This finally exposes also the methods of these 3 classes in the Prelude
in order to allow to define basic class instances w/o needing imports.

This almost completes the primary goal of #9586

NOTE: `fold`, `foldl'`, `foldr'`, and `toList` are not exposed yet,
      as they require upstream fixes for at least `containers` and
      `bytestring`, and are not required for defining basic instances.

We now define _PROGNAME, and _PROG is automatically defined with
$(exeext). This will shortly automatically use the right exeext
depending on what stage it is being compiled with (exeext may be
different for different stages when cross-compiling).
