摘要：
Techniques for representing a program are provided. The techniques include creating one or more sub-variables for each of one or more variables in the program, and maintaining a single size of each of the one or more variables throughout a life-span of each of the one or more variables. Additionally, techniques for performing register allocation are also provided. The techniques include representing bit-width information of each of one or more variables in a powers-of-two representation, wherein the one or more variables comprise one or more variables in a program, coalescing the one or more variables, packing the one or more coalesced variables, and using the one or more packed variables to perform register allocation.
