TBLGEN(1)

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.

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

-gen-instr-enums
    Generate enumeration values for instructions.

-gen-instr-desc
    Generate instruction descriptions.

-gen-asm-writer
    Generate the assembly writer.

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

-gen-subtarget
    Generate subtarget enumerations.

-gen-intrinsic
    Generate intrinsic information.

-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.
