[Bug target/40473] New: -mno-sched-prolog breaks function parameter debug location lists

[amodra at bigpond dot net dot au]

/* When compiled with -g -O -mno-sched-prolog, the debug info location
   lists for p1 and p2 do not cover the start of f.  There are other
   inaccuracies, but not covering the start of the function is specific
   to -nno-sched-prolog.  */
int f (int p1, int p2)
{
  extern int bar (int);
  int x, y;
  for (x = p1, y = 0; x < p2; x++)
    y += bar (x);
  return y;
