Interesting news worth to spread about the commercial LabVIEW :
In LabVIEW 2010, the DFIR offers new compiler optimizations such as algebraic reassociation, common subexpression elimination, loop unrolling, and subVI inlining. This release also includes the adoption of a Low-Level Virtual Machine (LLVM) into the LabVIEW compiler chain. LLVM is an open-source compiler infrastructure used widely in industry. With LLVM, new optimizations were added such as instruction scheduling, loop unswitching, instruction combining, conditional propagation, and a more sophisticated register allocator.
