| tblgen - Target Description To C++ Code Generator | |
| ================================================= | |
| SYNOPSIS | |
| -------- | |
| :program:`tblgen` [*options*] [*filename*] | |
| DESCRIPTION | |
| ----------- | |
| :program:`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 :program:`tblgen` is beyond the scope of this short | |
| introduction; please see the :doc:`introduction to TableGen | |
| <../TableGen/index>`. | |
| 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:: -dump-json | |
| Print a JSON representation of all records, suitable for further | |
| automated processing. | |
| .. 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 | |

| .. 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-enums | |
| Generate intrinsic enums. | |
| .. option:: -gen-intrinsic-impl | |
| Generate intrinsic implementation. | |
| .. 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. |
