The task for a function named foo is to increase the return value of the function bar (in register $v0) by 1 and return the result back to the caller. The code of the function_foo is shown below: _foo: jal_bar addi $v0, $v0, 1 jr $ra Assume that the function bar has been implemented. What is wrong with the function_foo above? a. Nothing is wrong. b. Function _foo cannot use $v0. c. It will not go back to the caller. d. The last instruction should be j $ra.Explanation / Answer
_foo: jal _bar //Jumps to the calculated address, and stored the return address in $ra.
addi $v0, $v0, 1 //Adds 1 to the value in $v0.
jr $ra //Jumps to address in register $ra.
So, nothing wrong with this function.
