ABSTRACT:
A method and system for executing a non-native stack-based instruction within a computer system is disclosed. In accordance with the method and system of the present invention, a computer system capable of executing a set of non-native stack-access instructions is provided which includes a system memory, an instruction set convertor, and a processor. The system memory is utilized to store the non-native stack-access instructions, and part of the system memory is utilized as a stack. The instruction set convertor is utilized to convert the non-native stack-access instructions to a set of native instructions. When encountering a block of non-native stack-access instructions which include paired push and pop stack operations, the instruction set convertor produces a set of native instructions that ignores paired push and pop stack operations and retains all relevant number values in general purpose registers. The processor then processes the native instructions from the instruction set convertor, in which the immediate paired push and pop operations are eliminated.
