Optimizing Code Size Through Procedural Abstraction

Abstract
Memory size is an important economic factor in the development of embedded systems. It is therefore desirable to find compiler optimization techniques that reduce the size of the generated code. One such code compression technique is procedural abstractions, where repeated occurances of equivalent code fragments are factored out into new subroutines. Previously, procedural abstractions has been applied at the machine code level in optimizing linkers or binary rewriting tools. We have investigate the prospects of applying procedural abstraction at the intermediate code level of a whole-program optimizing C compiler. Placing the optimization before register allocation makes it target independent, and will allow us to take advantage of powerful code selection, register allocation and code scheduling techniques.
