Interpreters and compilers are two different ways of implementing
programming languages. An interpreter directly executes its program
input. It is a concise definition of the semantics of a programming
language and is easily implemented. A compiler translates its program
input into another language. It is more difficult to construct, but
the code that it generates runs faster than interpreted code.
In this dissertation, we propose a transformation-based foundation for
deriving compilers from semantic specifications in the form of four
rules. These rules give apriori advice for staging, and allow
explicit compiler derivation that would be less succinct with partial
evaluation. When applied, these rules turn an interpreter that
directly executes its program input into a compiler that emits the
code that the interpreter would have executed.
We formalize the language syntax and semantics to be used for the
interpreter and the compiler, and also specify a notion of equality.
It is then possible to precisely state the transformation rules and to
prove both local and global correctness theorems. And although the
transformation rules were developed so as to apply to an interpreter
written in a denotational style, we consider how to modify
non-denotational interpreters so that the rules apply. Finally, we
illustrate these ideas by considering a larger example: a Prolog
implementation
