| 25 | DESCRIPTION |
| 26 | </h3> |
| 27 | |
| 28 | The lli command is the LLVM interpreter. It takes a program in LLVM bytecode |
| John Criswell | 511a491 | 2003-09-29 20:10:08 +0000 | [diff] [blame^] | 29 | format and executes it using an interpreter or a Just In Time (JIT) compiler. |
| 30 | <p> |
| 31 | |
| 32 | If filename is not specified, then lli reads its input from standard input. |
| 33 | <p> |
| 34 | The optional arguments specified on the command line are passed to the executed |
| 35 | program as arguments. |
| 36 | <p> |
| 37 | |
| 38 | <h3> |
| 39 | MAIN FUNCTION |
| 40 | </h3> |
| 41 | |
| 42 | The main() function of the bytecode program is where execution starts. It |
| 43 | is passed three arguments: |
| 44 | |
| 45 | <ul> |
| 46 | <li> |
| 47 | int argc - The number of command line arguments. |
| 48 | <p> |
| 49 | |
| 50 | <li> |
| 51 | char ** argv - The arguments to the program. |
| 52 | <p> |
| 53 | |
| 54 | <li> |
| 55 | char ** envp - An array of environment variables used by the program. |
| 56 | </ul> |
| 57 | |
| 58 | The first argument to the program is the name of the executed bytecode file |
| 59 | (with the .bc suffix removed). |
