11.9 Retargetable Code Generation
Retargetable code generation is a step towards automatic code generation. The code
generator is designed so that it can be changed to produce code for a new machine.
These may be categorized (Ganapathi et al., 1982) as (1) interpretive code generators,
(2) pattern matching code generators and (3) table-driven code generators. In all
of these, an attempt is made to separate the code generation algorithm from the
machine code itself. This fits our model of a driver and the information on which the
driver operates with the code generation algorithm analogous to the driver.
