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
