1 | LLVMCodegen |
| 2 | =========== | |
| 3 | ||
| 4 | The <:LLVMCodegen:> is a <:Codegen:code generator> that translates the | |
| 5 | <:Machine:> <:IntermediateLanguage:> to <:LLVM:> assembly, which is | |
| 6 | further optimized and compiled to native object code by the <:LLVM:> | |
| 7 | toolchain. | |
| 8 | ||
| 9 | It requires <:LLVM:> version 3.7 or greater to be installed. | |
| 10 | ||
| 11 | In benchmarks performed on the <:RunningOnAMD64:AMD64> architecture, | |
| 12 | code size with this generator is usually slightly smaller than either | |
| 13 | the <:AMD64Codegen:native> or the <:CCodegen:C> code generators. Compile | |
| 14 | time is worse than <:AMD64Codegen:native>, but slightly better than | |
| 15 | <:CCodegen:C>. Run time is often better than either <:AMD64Codegen:native> | |
| 16 | or <:CCodegen:C>. | |

| 25 | The <:LLVMCodegen:> was initially developed by Brian Leibig (see | |
| 26 | <!Cite(Leibig13,An LLVM Back-end for MLton)>). |
