Detailed Description

PhiTest1 class.

This function sets up an RVSDG representing the following code snippet:

static void
fib(uint64_t n, uint64_t result[])
{
  if (n < 2) {
    result[n] = n;
    return;
  }
 
  fib(n-1, result);
  fib(n-2, result);
  result[n] = result[n-1] + result[n-2];
}
 
void
test()
{
  uint64_t n = 10;
  uint64_t results[n];
 
  fib(n, results);
}

It uses a single memory state to sequentialize the respective memory operations.
