  • Replacing a variable in a use of the variable with a variant of the variable
    Patent number: 8141062
    Abstract: A method for optimizing a code section prior to performing register allocation for variables referenced in the plurality of computer instructions. The method includes performing at least one of a full prematerialization or a partial prematerialization for a variable in the plurality of computer instructions. The full prematerialization replaces the variable in every use of the variable in the plurality of computer instructions with one or more variants of the variable and replaces a definition of the variable with a nop instruction. The partial prematerialization replaces some but not all occurrences of the variable in uses of the variable in the plurality of computer instructions with one or more variants of the variable without replacing the definition of the variable with the nop instruction.
