Overview and industrial application of code generator generators

CGSS, BEG, TWIG and BURG are code generators finding increased industrial application. CGSS is an older Graham-Glanville style system based on pattern matching through parsing, whereas BEG, TWIG and BURG are more recent systems based on tree pattern matching combined with dynamic programming. The current technology of automatically generating code generators is viable in an industrial setting, although more research is needed regarding the problem of properly integrating register allocation and instruction scheduling with instruction selection, when both are generated from declarative specifications.
