| 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. |
| |

| |
| .. option:: -I directory |
| |
| Specify where to find other target description files for inclusion. The |

| .. option:: -asmparsernum N |
| |
| Make -gen-asm-parser emit assembly writer number ``N``. |
| |
| .. option:: -asmwriternum N |
| |

| |
| .. option:: -print-enums |
| |
| Print enumeration values for a class. |
