   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)>).
