This patch modifies TableGen to generate a function in ${TARGET}GenInstrInfo.inc called getNamedOperandIdx(), which can be used to look up indices for operands based on their names. In order to activate this feature for an instruction, you must set the UseNamedOperandTable bit. For example, if you have an instruction like: def ADD : TargetInstr <(outs GPR:$dst), (ins GPR:$src0, GPR:$src1)>; You can look up the operand indices using the new function, like this: Target::getNamedOperandIdx(Target::ADD, Target::OpName::dst) => 0 Target::getNamedOperandIdx(Target::ADD, Target::OpName::src0) => 1 Target::getNamedOperandIdx(Target::ADD, Target::OpName::src1) => 2 The operand names are case sensitive, so $dst and $DST are considered different operands. This change is useful for R600 which has instructions with a large number of operands, many of which model single bit instruction configuration values. These configuration bits are common across most instructions, but may have a different operand index depending on the instruction type. It is useful to have a convenient way to look up the operand indices, so these bits can be generically set on any instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184879 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`.
