tblgen - Target Description To C++ Code Generator
|
|
=================================================
|
|
|
|
SYNOPSIS
|
|
--------
|
|
|
|
:program:`tblgen` [*options*] [*filename*]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
:program:`tblgen` translates from target description (``.td``) files into C++
|
|
code that can be included in the definition of an LLVM target library. Most
|
|
users of LLVM will not need to use this program. It is only for assisting with
|
|
writing an LLVM target backend.
|
|
|
|
The input and output of :program:`tblgen` is beyond the scope of this short
|
|
introduction; please see the :doc:`introduction to TableGen
|
|
<../TableGen/index>`.
|
|
|
|
The *filename* argument specifies the name of a Target Description (``.td``)
|
|
file to read as input.
|
|
|
|
OPTIONS
|
|
-------
|
|
