| .IX Title "TBLGEN 1" |

| .SH "SYNOPSIS" |
| .IX Header "SYNOPSIS" |
| \&\fBtblgen\fR [\fIoptions\fR] [\fIfilename\fR] |
| .SH "DESCRIPTION" |
| .IX Header "DESCRIPTION" |
| \&\fBtblgen\fR translates from target description (.td) files into \*(C+ code that can |
| be included in the definition of an \s-1LLVM\s0 target library. Most users of \s-1LLVM\s0 will |
| not need to use this program. It is only for assisting with writing an \s-1LLVM\s0 |
| target backend. |
| .PP |
| The input and output of \fBtblgen\fR is beyond the scope of this short |
| introduction. Please see the \fICodeGeneration\fR page in the \s-1LLVM\s0 documentation. |
| .PP |
| The \fIfilename\fR argument specifies the name of a Target Description (.td) file |
| to read as input. |
| .SH "OPTIONS" |
| .IX Header "OPTIONS" |
| .IP "\fB\-\-help\fR" 4 |
| .IX Item "--help" |
| Print a summary of command line options. |
| .IP "\fB\-o\fR \fIfilename\fR" 4 |
| .IX Item "-o filename" |
| Specify the output file name. If \fIfilename\fR is \f(CW\*(C`\-\*(C'\fR, then \fBtblgen\fR |
| sends its output to standard output. |
| .IP "\fB\-I\fR \fIdirectory\fR" 4 |
| .IX Item "-I directory" |
| Specify where to find other target description files for inclusion. The |
| \&\fIdirectory\fR value should be a full or partial path to a directory that contains |
| target description files. |
| .IP "\fB\-asmwriternum\fR \fIN\fR" 4 |
| .IX Item "-asmwriternum N" |
| Make \-gen\-asm\-writer emit assembly writer number \fIN\fR. |

| .IX Item "-class class Name" |
| Print the enumeration list for this class. |
| .IP "\fB\-print\-records\fR" 4 |
| .IX Item "-print-records" |
| Print all records to standard output (default). |
| .IP "\fB\-print\-enums\fR" 4 |
| .IX Item "-print-enums" |
| Print enumeration values for a class |
| .IP "\fB\-gen\-emitter\fR" 4 |
| .IX Item "-gen-emitter" |
| Generate machine code emitter. |
| .IP "\fB\-gen\-register\-enums\fR" 4 |
| .IX Item "-gen-register-enums" |
| Generate the enumeration values for all registers. |

| Generate instruction descriptions. |
| .IP "\fB\-gen\-asm\-writer\fR" 4 |
| .IX Item "-gen-asm-writer" |
| Generate the assembly writer. |
| .IP "\fB\-gen\-dag\-isel\fR" 4 |
| .IX Item "-gen-dag-isel" |
| Generate a \s-1DAG\s0 (Directed Acycle Graph) instruction selector. |
| .IP "\fB\-gen\-subtarget\fR" 4 |
| .IX Item "-gen-subtarget" |
| Generate subtarget enumerations. |
