--- Comment #6 from Hongtao Liu <liuhongt at gcc dot gnu.org> ---
Looks correct in the gimple

int main (int argc, char * * D.3685)
{
  <bb 2> [local count: 1073741824]:
  # DEBUG BEGIN_STMT
  # DEBUG val => __complex__ (1.0e+0, 0.0)
  # DEBUG INLINE_ENTRY fun1
  __builtin_dwarf_cfa (0);
  # DEBUG BEGIN_STMT
  # DEBUG BEGIN_STMT
  # DEBUG BEGIN_STMT
  # DEBUG BEGIN_STMT
  printf ("%f\n", 1.0e+0);
  # DEBUG val => NULL
  return 0;
}


but goes wrong at expand.

explictly add printf ("%f\n", 1.0f); in the main

got gimple like below

__attribute__((access ("^1[ ]", )))
int main (int argc, char * * D.3685)
{
  <bb 2> [local count: 1073741824]:
  # DEBUG BEGIN_STMT
  # DEBUG val => __complex__ (1.0e+0, 0.0)
  # DEBUG INLINE_ENTRY fun1
  __builtin_dwarf_cfa (0);
  # DEBUG BEGIN_STMT
  # DEBUG BEGIN_STMT
  # DEBUG BEGIN_STMT
  # DEBUG BEGIN_STMT
  printf ("%f\n", 1.0e+0);
  # DEBUG val => NULL
  # DEBUG BEGIN_STMT
  printf ("%f\n", 1.0e+0);
  return 0;

}

but printf 0.0 and 1.0 differently.
