ABSTRACT:
In a compiler for processing a software program and generating machine executable code, a method for optimizing a plurality of variables that have their addresses taken. The method is comprised of the steps of processing source code in a front end of the compiler, to determine a plurality of variables that have their addresses taken. The compiler then analyzes local calls for the plurality of variable that have their addresses taken and determines which local variables may be safely optimized. The compiler then analyzes global calls for the plurality of variables that have their addresses taken and determines which global variables may be safely optimized. The compiler then optimizes the code by moving the code containing local variables and global variables outside of the code loops in the software program.
