[Flang] Fix release blocker issue #46931 related to documentation.

[sameeranjoshi]

Summary

Support for sphinx builds.
This commit add a new flag -DLLVM_ENABLE_SPHINX=ON to cmake command to generate sphinx documentation, along with new targets docs-flang-html and docs-flang-man the latter target doesn't work currently, as the command line options are not yet documented for flang.

ninja docs-flang-html - generates sphinx documentation.
Generated release notes can be found in tools/flang/docs/html/ folder.

Should this date be changed? If so what should be the right date ?

Why do you need to copy files from llvm?

Sphinx comes with a set of built-in themes for webpages[1], I thought of sticking with the llvm style of release notes, so to add some custom theme not in built-in themes list you need respective files.

[DavidTruby]

Thanks for adding all this infrastructure!
I don't see any CMake changes here though, where is the new flag added?

Sticking to llvm style sounds good. But as soon as it is changed in llvm we won't match the llvm style any more. Does clang have copies like this too?

I believe clang uses some cmake infrastructure to get doxygen and sphinx to pick up the theming stuff from LLVM. I at least can't see copies in clang.

It was added with doxygen commits

I believe clang uses some cmake infrastructure to get doxygen and sphinx to pick up the theming stuff from LLVM. I at least can't see copies in clang.

There is a configuration variable html_theme in each sub-project supporting sphinx, I tried to grep "html_theme" -r here's the summary.
clang, libcxx, clang-tools-extra, libunwind - Use built-in theme haiku
llvm, flang, lld - Use custom llvm based theme llvm-theme
lldb - Uses alabaster as one of the built-in themes.

Checking the git blame logs for these files in llvm and in lld shows they weren't modified since 2012, so they seem to be pretty consistent since then.

[DavidTruby]

Oh I see, I didn't realise clang uses the default theme not the LLVM one! If lld also copies these files I think it is fine for us to do so as well.

Regarding the release note contents. My original review proposing these did not get any strong objections so I propose that once we are all happy with the code that this initial version of the release notes be committed alongside. I will make a follow up review with any further edits to it before release.

Alternative plan might be to add my master placeholder release note from https://reviews.llvm.org/D84867 instead of the version specific to the LLVM11 branch from https://reviews.llvm.org/D84864

[richard.barton.arm]

These changes build for me and I get a .html version of the flang release notes in the docs directory in the build. It is a shame there is not more content there and I suppose we'll need to convert the docs in /documentation over to .rst format to get them included in this set.

As pointed out in the developer call today. There does not seem to be much objection to this change, and it is successfully building so I am happy to approve it. Please wait a day or so to give a chance for others to intervene if they want further changes.

I think this should be 2017.

Updated copyright year.

Merged to 11.x in b0b18ec9e8a7e7c7ca6e01d1a6f636622fa59941. Thanks!

It would probably make sense to have an index.rst file too, to generate index.html.

+Flang 11.0.0 (In-Progress) Release Notes
+========================================
+
+.. contents::
+   :local:
+   :depth: 2
+
+.. warning::
+
+   These are in-progress notes for the upcoming LLVM 11.0.0 release.
+   Release notes for previous releases can be found on
+   `the Download Page <https://releases.llvm.org/download.html>`_.
+
+Introduction
+============
+
+This document contains the release notes for the Flang Fortran
+frontend, part of the LLVM Compiler Infrastructure, release 11.0.0. Here we
+describe the status of Flang in some detail, including major
+improvements from the previous release and new feature work. For the
+general LLVM release notes, see `the LLVM
+documentation <https://llvm.org/docs/ReleaseNotes.html>`_. All LLVM
+releases may be downloaded from the `LLVM releases web
+site <https://llvm.org/releases/>`_.
+
+Note that if you are reading this file from a Git checkout, this document
+applies to the *next* release, not
+the current one. To see the release notes for a specific release, please
+see the `releases page <https://llvm.org/releases/>`_.
+
+Known Issues
+============
+
+These are issues that couldn't be fixed before the release. See the bug reports for the latest status.
+
+- ...
+
+Introducing Flang
+=================
+
+Flang is LLVM's Fortran front end and is new for the LLVM 11 release.
+
+Flang is still a work in progress for this release and is included for
+experimentation and feedback.
+
+Flang status
+------------
+
+Flang is able to parse a comprehensive subset of the Fortran language
+and check it for correctness. Flang is not yet able to generate LLVM IR for
+the source code and thus is unable to compile a running binary. 
+
+Flang is able to unparse the input source code into a canonical form and emit
+it to allow testing. Flang can also invoke an external Fortran compiler on this
+canonical input.
+
+Flang's parser has comprehensive support for:
+- Fortran 2018
+- OpenMP 4.5
+- OpenACC 3.0
+
+Major missing features
+----------------------
+
+- Flang is not supported on Windows platforms.
+
+Using Flang
+===========
+
+Usage: ``flang hello.f90 -o hello.bin``
+
+Flang will parse the Fortran file ``hello.f90`` then unparse it to a canonical
+Fortran source file. Flang will then invoke an external Fortran compiler to
+compile this source file and link it, placing the resulting executable
+in ``hello.bin``.
+
+To specify the external Fortran compiler, set the ``F18_FC`` environment
+variable to the name of the compiler binary and ensure it is on your ``PATH``.
+The default value for ``F18_FC`` is ``gfortran``.
+
+When invoked with no source input, Flang will wait for input on standard in.
+When invoked in this way, Flang performs the same actions as if called with
+``-fdebug-measure-parse-tree -funparse`` and does not invoke ``F18_FC``.
+
+For a full list of options that Flang supports, run ``flang --help``.
+
+Additional Information
+======================
+
+Flang's documentation is located in the ``flang/docs/`` directory in
+the LLVM monorepo.
+
+If you have any questions or comments about Flang, please feel free to
+contact us via the `mailing
+list <https://lists.llvm.org/mailman/listinfo/flang-dev>`_.
