My brain's too small for such a big testcase.  Further reduced testcase, and

reduced arguments.



// ./cc1 -quiet -O2 a.c  -march=z10   -fPIC -I /tmp

static int glob_a, glob_b;



int foobar()

{

  char buffer[100];



  glob_a = 0;

  glob_b = 0;



  bar (buffer);



  __builtin_memcpy(buffer, "abc", 3);



  buffer[7] = (char)(glob_a >> 8);

  buffer[11] = (char)glob_b;

  buffer[13] = (char)glob_a;

  buffer[17] = (char)(glob_a >> 8);



  return foo(0, 0, 0, 0);

}
