tblgen - Target Description To C++ Code Generator
|
|
=================================================
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
|
|
|
|
**tblgen** [*options*] [*filename*]
|
|
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
|
|
**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 **tblgen** is beyond the scope of this short
|
|
introduction. Please see the *CodeGeneration* page in the LLVM documentation.
|
|
|
|
The *filename* argument specifies the name of a Target Description (.td) file
|
|
to read as input.
|
|
|
|
|
