Write a leaf procedure with the following prototype long long int strlen(char buffer[]); It should return the number of characters in the character array buffer (by starting at index zero and looking at the characters in the array. The "sentinel" character at the end is '\0' which is also the number zero and this should not be counted) A good first step with this is to write the Java code that will do this calculation. Instruction Description Initialize counter register X9 to zero Compute the absolute address of buffer_i storing in X10 Load buffer_i into X10. Branch to STRLEN_RETURN label if buffer_i is zero. Increment counter register by 1. Label STRLEN STRLEN LOOP Branch to the STRLEN LOOP label. STRLEN RETURN Copy value of the counter to XO. Return to the caller
