.SH SYNOPSIS
|
|
.sp
|
|
\fBtblgen\fP [\fIoptions\fP] [\fIfilename\fP]
|
|
.SH DESCRIPTION
|
|
.sp
|
|
\fBtblgen\fP 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.
|
|
.sp
|
|
The input and output of \fBtblgen\fP is beyond the scope of this short
|
|
introduction. Please see the \fICodeGeneration\fP page in the LLVM documentation.
|
|
.sp
|
|
The \fIfilename\fP argument specifies the name of a Target Description (.td) file
|
|
to read as input.
