Behind the Scenes of the LabVIEW Compiler
summary
History of the LabVIEW compiler shows concrete moves: diagrams become a DFIR intermediate form, many transforms run there (type propagation, inlining, dead‑code elimination), and codegen switches to LLVM around 2010 so ARM and SSE arrive without bespoke backends. Execution groups called clumps and memory reuse called implaceness decide copies versus parallelism. Benchmarks can mislead because clumping, stomping and UI thread switches change behavior; compiled bits aim to be deterministic though EXE packaging can vary.
