| 14 | NAME |
| 15 | </h3> |
| 16 | |
| 17 | llc |
| 18 | |
| 19 | <h3> |
| 20 | SYNOPSIS |
| 21 | </h3> |
| 22 | |
| 23 | llc [options] < filename> |
| 24 | <h3> |
| 25 | DESCRIPTION |
| 26 | </h3> |
| 27 | |
| 28 | The llc command compiles LLVM bytecode into assembly language for a specified |
| 29 | architecture. The assembly language output can then be passed through a native |
| 30 | assembler and linker to generate native code. |
| 31 | |
