\&\fBtblgen\fR translates from target description (.td) files into \*(C+ code that can
|
|
be included in the definition of an \s-1LLVM\s0 target library. Most users of \s-1LLVM\s0 will
|
|
not need to use this program. It is only for assisting with writing an \s-1LLVM\s0
|
|
target backend.

The input and output of \fBtblgen\fR is beyond the scope of this short
|
|
introduction. Please see the \fICodeGeneration\fR page in the \s-1LLVM\s0 documentation.
