In the LC-2200 cаlling cоnventiоn, the 6 generаl purpоse registers аre divided into 3 caller-saved ($t) registers and 3 callee-saved ($s) registers. The pseudocode snippet below demonstrates a sequence of function calls: main calls foo once foo calls bar 10 times int bar(int x) { int sum = 0; for(int i = 0; i < x; i++){ sum += i; } return sum;}void foo(){ int n = 0; for(int i = 0; i < 10; i++){ int x = i * 3; n+= bar(x); } printf("%dn",n);}int main(){ int code = -1; foo(); return code;} When the compiler is allocating registers to certain variables, which of the following allocations will provide an optimal number of saves/loads with respect to the calling convention?
