| LLVM representation consists of two stages - layout independent |
| intermediate representation gallivm_ir and driver specific |
| gallivm_prog. TGSI is first being translated into gallivm_ir |
| after that driver can set number of options on gallivm_ir and |
| have it compiled into gallivm_prog. gallivm_prog can be either |
| executed (assuming there's LLVM JIT backend for the current |
| target) or machine code generation can be done (assuming there's |
| a LLVM code generator for thecurrent target) |
