Intermediate language format in an optimizing compiler.

摘要

An intermediate language representation of a program facilitates optimizing transformations on a computer program being compiled. The language representation is termed a "bag" which is a self describing piece of data that allows for a flexible, low cost, and accurate way of performing a desired operation. The bag carries computational information in a way that allows it to be reused later. In addition, it allows the final code generation to take advantage of the hardware for which the code is targeted.
