Pyster “describes the state of compiler art.” (Appeal
Br. at 11.) Figure 1-6 of the reference depicts the
transformation of source code into object code “by a series of
transformations of it ....” P. 11. The transformations
include scanning source code, Fig. 1-6, which has been input
into a compiler; generating an intermediate code representing
the source code, Id., processing the intermediate code to
generate an optimized intermediate representation, Figs. 1-6
and 1-14; and processing said optimized intermediate
representation to generate the object code. Fig. 1-6, P. 21.
