    Message : Import LLVM 8.0.1 release including clang, lld and lldb.

  • README.txt
  • 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
