NAME

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.
