compiler or, rather, interposed with an optimizer. Claim 1 is
illustrative of the claimed invention, and it reads as
follows:
1. A method for optimizing and transforming a
compiler program in a computer system, the method
comprising the steps of:
(1) constructing a compiler having means for
utilizing global dependency information and
redundant expression elimination to augment
mathematical functions in a source program; and
(2) locating said augmentation means interposed
and internal to phases of the compiler standard
compilation process to access said global dependency
information.
