Class SVM_DIST

java.lang.Object

svm.instruction.SVM_Instruction

svm.instruction.SVM_DIST

public class SVM_DIST
extends SVM_Instruction

SVM-INSTRUCTION: DIST

Runtime Stack
   ..., sos, tos →
   ..., result

The 'tos' and 'sos' are popped off the Runtime stack.
The 'result' is calculated as result = sos - tos.
Then the 'result' is pushed onto the Runtime Stack.

'tos' and 'sos' must be of the type oaddr.
