| 26 | </h3> |
| 27 | |
Brian Gaeke | 51b2ab8 | 2003-10-19 18:03:11 +0000 | [diff] [blame] | 28 | <tt>lli</tt> directly executes programs in LLVM format. |
| 29 | It takes a program in LLVM |
| 30 | bytecode format and executes it using a just-in-time |
| 31 | compiler, if one is available for the current architecture, or an interpreter. |
| 32 | <tt>lli</tt> takes all of the same code generator options as the |
| 33 | <tt><a href="llc.html">llc</a></tt> tool, but they are only applicable when |
| 34 | the just-in-time compiler is being used. |
John Criswell | 511a491 | 2003-09-29 20:10:08 +0000 | [diff] [blame] | 35 | <p> |
| 36 | |
Brian Gaeke | 51b2ab8 | 2003-10-19 18:03:11 +0000 | [diff] [blame] | 37 | If filename is not specified, then <tt>lli</tt> reads the LLVM bytecode for |
| 38 | the program from standard input. |
John Criswell | 511a491 | 2003-09-29 20:10:08 +0000 | [diff] [blame] | 39 | <p> |
Brian Gaeke | 51b2ab8 | 2003-10-19 18:03:11 +0000 | [diff] [blame] | 40 | The optional "args" specified on the command line are passed to the |
John Criswell | 511a491 | 2003-09-29 20:10:08 +0000 | [diff] [blame] | 41 | program as arguments. |

| 67 | <li> <tt>-march=<arch></tt> |
| 68 | <br> |
| 69 | Use the specified non-default architecture when selecting a code generator |
| 70 | for the just-in-time compiler. This may result in a crash if you pick an |
| 71 | architecture which is not compatible with the hardware you are running |
| 72 | <tt>lli</tt> on. |
| 73 | <p> |
| 74 | |
Brian Gaeke | 51b2ab8 | 2003-10-19 18:03:11 +0000 | [diff] [blame] | 75 | <li> <tt>-force-interpreter={false,true}</tt> |
| 76 | <br> |
| 77 | If set to true, use the interpreter even if a just-in-time compiler is |
| 78 | available for this architecture. Defaults to false. |
| 79 | <p> |
| 80 | |
Brian Gaeke | 51b2ab8 | 2003-10-19 18:03:11 +0000 | [diff] [blame] | 81 | <li> <tt>-f=<name></tt> |
| 82 | <br> |
| 83 | Call the function named <tt><name></tt> to start the program. |
| 84 | Note: The function is assumed to have the C signature <tt>int |
| 85 | <tt><name></tt> (int, char **, char **)</tt>. |
| 86 | If you try to use this option to call a function of incompatible type, |
| 87 | undefined behavior may result. Defaults to "main". |

| 97 | Otherwise, it will return the exit code of the program it executes. |
