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 introduction to TableGen.

       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.

       -asmparsernum N
	      Make -gen-asm-parser emit assembly writer number N.

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

       -class className
	      Print the enumeration list for this class.

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

       -print-enums
	      Print enumeration values for a class.

       -print-sets
	      Print expanded sets for testing DAG exprs.

       -gen-emitter
	      Generate machine code emitter.

       -gen-register-info
	      Generate registers and register classes info.

       -gen-instr-info
	      Generate instruction descriptions.

       -gen-asm-writer
	      Generate the assembly writer.

       -gen-disassembler
	      Generate disassembler.

       -gen-pseudo-lowering
	      Generate pseudo instruction lowering.

       -gen-dag-isel
	      Generate a DAG (Directed Acycle Graph) instruction selector.

       -gen-asm-matcher
	      Generate assembly instruction matcher.

       -gen-dfa-packetizer
	      Generate DFA Packetizer for VLIW targets.

       -gen-fast-isel
	      Generate a "fast" instruction selector.

       -gen-subtarget
	      Generate subtarget enumerations.

       -gen-intrinsic
	      Generate intrinsic information.

       -gen-tgt-intrinsic
	      Generate target intrinsic information.

       -gen-enhanced-disassembly-info
	      Generate enhanced disassembly info.

       -version
	      Show the version number of this program.

EXIT STATUS
       If tblgen succeeds, it will exit with 0.  Otherwise, if an error occurs, it will exit with a non-zero value.
