A Code Generation Interface for ANSI C is a retargetable, production
compiler for ANSI C; versions for the VAX, the Motorola 68020 and MIPS
have been in use for over a year and a half. It is smaller and faster
than generally available alternatives, and its local code is about as
good. This report describes the interface between the
target-independent front end and the target-dependent back ends. The
interface consists of shared data structures, a few functions, and a
dag language. While this approach couples the front and back ends
tightly, it results in an efficient, compact compiler. The interface
is illustrated by detailing a complete code generator that emits naive
VAS code.
