Abstract
A developer's system compiles a source-language program by parsing it into an intermediate language (IL) program that is independent of the architecture or resources of any particular processor. This system generates a set of machine independent annotations that record attributes and structure of the IL program such as variable definitions and uses. The annotations are in the form of a unique graph structure. Further annotations are used to associate the machine specific optimization information with each of many different microprocessors. The IL program and all the annotations are distributed to multiple user systems having mutually different virtual machines that translate the IL program into object language for their respective different processors. Optimizers in the virtual machines select graph edges based on the machine specific annotations to generate an optimized object program. The translators are table-driven. Entities in the IL program are keyed to entries in a replaceable table in each virtual machine.
