|  | NAME | 
|  | </h3> | 
|  |  | 
|  | extract | 
|  |  | 
|  | <h3> | 
|  | SYNOPSIS | 
|  | </h3> | 
|  |  | 
|  | extract [options] [filename] | 
|  | <h3> | 
|  | DESCRIPTION | 
|  | </h3> | 
|  |  | 
|  | The extract command takes the name of a function and extracts it from the | 
|  | specified LLVM bytecode file.  It is primarily used as a debugging tool to | 
|  | reduce test cases from larger programs that are triggering a bug. | 
|  | <p> | 
|  |  | 
|  | In addition to extracting the bytecode of the specified function, extract will | 
|  | also remove unreachable global variables, prototypes, and unused types. | 
|  | <p> | 
|  |  | 
|  | The extract command will read its input from standard input if filename is | 
|  | omitted or if filename is -.  The output is always written to standard output. | 
|  |  | 
|  | <h3> | 
|  | OPTIONS | 
|  | </h3> | 
|  |  | 
|  | <ul> | 
|  | <li>-func <function> |

|  | <li> -time-passes | 
|  | <br> |

|  |  | 
|  | <h3> | 
|  | EXIT STATUS | 
|  | </h3> |
