Suppose you want to make a nested function call (i. e. a call to a function from inside of another function) using a jal rather than a call for performance reasons.

how would the push and pop pseudo-ops be proprely ordered along with the jal so that the previous return address isn't lost?

a) pop $ra
jal nested_function_label
nop
push $ra

b) push $ra
jal nested_function_label
nop
push $ra

c) push $ra
pop $ra
jal nested_function_label
nop

d) jal nested_function_label
nop
pop $ra
push $ra

Suppose that i have the following function declaration: struct x_struct my_function( struct x_struct val ); while this is legal, it suffers from an inefficiency. what is the problem? a. i have no idea. this is not the b. the function will execute slowly because "val", and the return value of the function will both require a lot of data copying. this is because c is call-by-value. c. the function can not alter the original value of "val", so passing it is not useful. d. the function can alter the original structure "val", making the code hard to follow. e. the function will execute slowly because "val", and the return value of the function will both require a lot of data copying. this is because c is call-by-reference.
