| 31 | <div class="paragraph"><p>The <a href="LLVMCodegen">LLVMCodegen</a> is a <a href="Codegen">code generator</a> that translates the\r | |
| 32 | <a href="Machine">Machine</a> <a href="IntermediateLanguage">IntermediateLanguage</a> to <a href="LLVM">LLVM</a> assembly, which is\r | |
| 33 | further optimized and compiled to native object code by the <a href="LLVM">LLVM</a>\r | |
| 34 | toolchain.</p></div>\r | |
| 35 | <div class="paragraph"><p>It requires <a href="LLVM">LLVM</a> version 3.7 or greater to be installed.</p></div>\r | |
| 36 | <div class="paragraph"><p>In benchmarks performed on the <a href="RunningOnAMD64">AMD64</a> architecture,\r | |
| 37 | code size with this generator is usually slightly smaller than either\r | |
| 38 | the <a href="AMD64Codegen">native</a> or the <a href="CCodegen">C</a> code generators. Compile\r | |
| 39 | time is worse than <a href="AMD64Codegen">native</a>, but slightly better than\r | |
| 40 | <a href="CCodegen">C</a>. Run time is often better than either <a href="AMD64Codegen">native</a>\r | |
