  • Estimation of bit widths of variables based on liveness
    Patent number: 10180826
    Abstract: A compiler generates transfer functions for blocks of a program during compilation of the program. The transfer functions estimate bit widths of variables in the blocks based on numbers of bits needed to carry out at least one instruction in the blocks and whether the variables are live in the blocks. For example, a transfer function may return a number indicating how many bits of a variable are needed to execute a current instruction as a function of the number of bits of the variable used by the program in subsequent instructions. Numbers of bits to represent the variables in the compiled program based on the transfer functions.
