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 :program:`tblgen` is beyond the scope of this short +introduction. Please see :doc:`../TableGenFundamentals`. + +The *filename* argument specifies the name of a Target Description (``.td``) +file to read as input. + +OPTIONS +------- + +.. program:: tblgen + +.. option:: -help + + Print a summary of command line options. + +.. option:: -o filename + + Specify the output file name. If ``filename`` is ``-``, then + :program:`tblgen` sends its output to standard output. + +.. option:: -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. + +.. option:: -asmparsernum N + + Make -gen-asm-parser emit assembly writer number ``N``. + +.. option:: -asmwriternum N + + Make -gen-asm-writer emit assembly writer number ``N``. + +.. option:: -class className + + Print the enumeration list for this class. + +.. option:: -print-records + + Print all records to standard output (default). + +.. option:: -print-enums + + Print enumeration values for a class. + +.. option:: -print-sets + + Print expanded sets for testing DAG exprs. + +.. option:: -gen-emitter + + Generate machine code emitter. + +.. option:: -gen-register-info + + Generate registers and register classes info. + +.. option:: -gen-instr-info + + Generate instruction descriptions. + +.. option:: -gen-asm-writer + + Generate the assembly writer. + +.. option:: -gen-disassembler + + Generate disassembler. + +.. option:: -gen-pseudo-lowering + + Generate pseudo instruction lowering. + +.. option:: -gen-dag-isel + + Generate a DAG (Directed Acycle Graph) instruction selector. + +.. option:: -gen-asm-matcher + + Generate assembly instruction matcher. + +.. option:: -gen-dfa-packetizer + + Generate DFA Packetizer for VLIW targets. + +.. option:: -gen-fast-isel + + Generate a "fast" instruction selector. + +.. option:: -gen-subtarget + + Generate subtarget enumerations. + +.. option:: -gen-intrinsic + + Generate intrinsic information. + +.. option:: -gen-tgt-intrinsic + + Generate target intrinsic information. + +.. option:: -gen-enhanced-disassembly-info + + Generate enhanced disassembly info. + +.. option:: -version + + Show the version number of this program. + +EXIT STATUS +----------- + +If :program:`tblgen` succeeds, it will exit with 0. Otherwise, if an error +occurs, it will exit with a non-zero value.
