Optimization aspects of compiler- compilers

A decade of experience with prototype versions of compiler-compilers, some of which have been successful and some of which have not been so successful, leads us to the conclusion that we can now engineer good compiler-compilers which can generate efficient compilers that generate efficient object code. This paper reviews the experience with compiler-compilers, documents reasons for believing that some compiler-compilers are good, and advocates the importation of compiler-compiler techniques by commercial firms and the production of well-engineered compiler-compilers as commercial products. Some unanswered questions about compiler-compiler techniques are explored in relation to the newly emerging discipline of software engineering.
