Write the RISC-V assembly code to implement the following C code as an atomic “set max” operation using the lr.d/sc.d instructions. Here, the argument shvar contains the address of a shared variable which should be replaced by x if x is greater than the value it points to:

void setmax(int* shvar, int x) {

// Begin critical section

if (x > *shvar)

*shvar = x;

// End critical section

}

}
