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.

OPTIONS
       -help
           Print a summary of command line options.

       -o filename
           Specify the output file name.  If filename is "-", then tblgen
           sends its output to standard output.

       -I directory
           Specify where to find other target description files for inclusion.
           The directory value should be a full or partial path to a directory
           that contains target description files.

       -asmwriternum N
           Make -gen-asm-writer emit assembly writer number N.

       -class class Name
           Print the enumeration list for this class.

       -print-records
           Print all records to standard output (default).

       -print-enums
           Print enumeration values for a class

       -gen-emitter
           Generate machine code emitter.

       -gen-register-enums
           Generate the enumeration values for all registers.

       -gen-register-desc
           Generate a register info description for each register.

       occurs, it will exit with a non-zero value.
