The grammar for LLVM IR is not well specified in any document but seems to obey the following rules: - Attributes which have parenthesized arguments are never preceded by commas. This form of attribute is the only one which ever has optional arguments. However, not all of these attributes support optional arguments: 'thread_local' supports an optional argument but 'addrspace' does not. Interestingly, 'addrspace' is documented as being a "qualifier". What constitutes a qualifier? I cannot find a definition. - Some attributes use a space between the keyword and the value. Examples of this form are 'align' and 'section'. These are always preceded by a comma. - Otherwise, the attribute has no argument. These attributes do not have a preceding comma. Sometimes an attribute goes before the instruction, between the instruction and it's type, or after it's type. 'atomicrmw' has 'volatile' between the instruction and the type while 'call' has 'tail' preceding the instruction. With all this in mind, it seems most consistent for 'inalloca' on an 'inalloca' instruction to occur before between the instruction and the type. Unlike the current formulation, there would be no preceding comma. The combination 'alloca inalloca' doesn't look particularly appetizing, perhaps a better spelling of 'inalloca' is down the road. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203376 91177308-0d34-0410-b5e6-96231b3b80d8 |

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 docs/ make -f Makefile.sphinx $BROWSER _build/html/index.html The mapping between reStructuredText files and generated documentation is `docs/Foo.rst` <-> `_build/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/man/`. cd docs/ make -f Makefile.sphinx man man -l _build/man/FileCheck.1 The correspondence between .rst files and man pages is `docs/CommandGuide/Foo.rst` <-> `_build/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`.
