Abstract:In a program, not all the bits of a variable are always used during execution. Identifying the minimum number of bits necessary to represent a variable in a program can potentially provide optimization opportunities. Providing the knowledge of bitwidths to a compilation and execution framework will be advantageous if it could use that information to optimize the execution of the program, for instance, being able to select instructions for SIMD vectorization. This paper introduces a framework to exploit the pot… Show more
