             Bug #: 53640
           Summary: Missed cmove with stores
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: tree-optimization
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: pins...@gcc.gnu.org


Take:
int f(int a, int *b)
{
  if (a >= 2)
    *b = 1;
  else
    *b = 0;

  return *b;
}

int f1(int a, int *b)
{
  int t;
  if (a >= 2)
    t = 1;
  else
    t = 0;
  *b = t;

  return *b;
}

---- CUT ----
Both of these are the same.  f1 will produce better code.
