[tree-ssa] USE or VUSE bugs?

[Wei Liu]

I have a very simple kernel as follows. The problem is, for statement
a=b+c, there is no USE or VUSE I can get from get_ops and get_vops. So
this statement seems to me no use operands. It is really weird, because I
suppose I can all operands from get_ops and get_vops.

Any suggestions are greatly appreciated. Thanks.

---------------------------------------------
void foo1 (const char *);
int foo2(float *in, float *in2);
float a;


int func(int *in, int in2)
{
  float b, c;
  int i;

  for (i = 0; i < 10; i++)
    {
      foo1("yes");
      foo2 (&b, &c);

      *in = in2;
      a = b + c;
    }
}
