The Three-Stage Compiler
Captions available
The idea
Compilation runs in stages — a front end deconstructing source, a middle end optimizing execution time and memory, a back end generating code — a symbol table tracking identifiers throughout.
In practice
A freight run of intake, repacking for efficiency, and final delivery mirrors the pipeline.
Where people slip
Optimization is a stage with a budget, not magic.
