Abstract:
A technique for reducing stack pointer adjustment operations when stack dependent operations, which correspond to stack dependent instructions, are encountered includes setting a stack pointer to an initial value for a stack. A number of bytes associated with the stack dependent operation is determined. A stack pointer delta is then modified based upon the number of bytes associated with the stack dependent operation. A current location in the stack is determined based on the stack pointer and the stack pointer delta.
