Abstract
A system and method for early platform dependency preparation of intermediate code representation during bytecode compilation in a virtual machine (VM), or other runtime environment, and particularly for use in a system that includes a Java Virtual Machine (JVM). Current techniques for separating the platform dependent intermediate representation from the platform independent intermediate representation using a watertight abstraction layer gives non-optimal side effects (such as compiler source code duplication or inefficiency in the generated code). Embodiments of the present invention enable the compiler to construct platform dependent idioms using medium level intermediate code, and maintain the platform dependent construct all the way to the final native code.
