[Bug target/27758] New: [4.1 regression] -O0 -fpic link failure

[jakub at gcc dot gnu dot org]

/* { dg-do run { target fpic } } */
/* { dg-options "-O0 -fpic" } */

typedef int (*fn) (void);

static inline int
foo (void)
{
  return 1;
}

fn
test (void)
{
  return foo;
}

int
main (void)
{
  fn f = test ();
  return f () != 1;
}

doesn't link on i386/x86_64 in 4.1 (regression from 4.0) - function foo isn't
marked as referenced and therefore not emitted.
This was fixed on the trunk in PR25758.

Will not be fixed in 4.1.1; adjust target milestone to 4.1.2.
