[Bug tree-optimization/35806] New: Object code is bigger at -Os than at -O2

[mstein dot lists at googlemail dot com]

Hi,
the code below compiles to 60 byte when using -Os
and 4 byte when using -O2.

This is just one example of many from the test suite: 

extern void f(char *const *);
void g (char **o)
{
  static const char *const multilib_exclusions_raw[] = { 0 };
  const char *const *q = multilib_exclusions_raw;

  f (o);
  while (*q++)
    f (o);
}
