Summary: This addresses http://llvm.org/PR36790. The change Deprecates a number of functions and types in `include/xray/xray_log_interface.h` to recommend using string-based configuration of XRay through the __xray_log_init_mode(...) function. In particular, this deprecates the following: - `__xray_set_log_impl(...)` -- users should instead use the `__xray_log_register_mode(...)` and `__xray_log_select_mode(...)` APIs. - `__xray_log_init(...)` -- users should instead use the `__xray_log_init_mode(...)` function, which also requires using the `__xray_log_register_mode(...)` and `__xray_log_select_mode(...)` functionality. - `__xray::FDRLoggingOptions` -- in following patches, we'll be migrating the FDR logging implementations (and tests) to use the string-based configuration. In later stages we'll remove the `__xray::FDRLoggingOptions` type, and ask users to migrate to using the string-based configuration mechanism instead. - `__xray::BasicLoggingOptions` -- same as `__xray::FDRLoggingOptions`, we'll be removing this type later and instead rely exclusively on the string-based configuration API. We also update the documentation to reflect the new advice and remove some of the deprecated notes.

LLVM Documentation
==================
LLVM's documentation is written in reStructuredText, a lightweight
plaintext markup language (file extension `.rst`). While the
reStructuredText documentation should be quite readable in source form, it
is mostly meant to be processed by the Sphinx documentation generation
system to create HTML pages which are hosted on <http://llvm.org/docs/> and
updated after every commit. Manpage output is also supported, see below.
If you instead would like to generate and view the HTML locally, install
Sphinx <http://sphinx-doc.org/> and then do:
cd <build-dir>
cmake -DLLVM_ENABLE_SPHINX=true -DSPHINX_OUTPUT_HTML=true <src-dir>
make -j3 docs-llvm-html
$BROWSER <build-dir>/docs//html/index.html
The mapping between reStructuredText files and generated documentation is
`docs/Foo.rst` <-> `<build-dir>/docs//html/Foo.html` <-> `http://llvm.org/docs/Foo.html`.
If you are interested in writing new documentation, you will want to read
`SphinxQuickstartTemplate.rst` which will get you writing documentation
very fast and includes examples of the most important reStructuredText
markup syntax.
Manpage Output
===============
Building the manpages is similar to building the HTML documentation. The
primary difference is to use the `man` makefile target, instead of the
default (which is `html`). Sphinx then produces the man pages in the
directory `<build-dir>/docs/man/`.
cd <build-dir>
cmake -DLLVM_ENABLE_SPHINX=true -DSPHINX_OUTPUT_MAN=true <src-dir>
make -j3 docs-llvm-man
man -l >build-dir>/docs/man/FileCheck.1
The correspondence between .rst files and man pages is
`docs/CommandGuide/Foo.rst` <-> `<build-dir>/docs//man/Foo.1`.
These .rst files are also included during HTML generation so they are also
viewable online (as noted above) at e.g.
`http://llvm.org/docs/CommandGuide/Foo.html`.
Checking links
==============
The reachability of external links in the documentation can be checked by
running:
cd docs/
make -f Makefile.sphinx linkcheck
Doxygen page Output
==============
Install doxygen <http://www.stack.nl/~dimitri/doxygen/download.html> and dot2tex <https://dot2tex.readthedocs.io/en/latest>.
cd <build-dir>
cmake -DLLVM_ENABLE_DOXYGEN=On <llvm-top-src-dir>
make doxygen-llvm # for LLVM docs
make doxygen-clang # for clang docs
It will generate html in
<build-dir>/docs/doxygen/html # for LLVM docs
<build-dir>/tools/clang/docs/doxygen/html # for clang docs
