[Bug middle-end/42674] [4.4/4.5 Regression] Bogus "no return statement in function returning non-void" warning

[jakub at gcc dot gnu dot org]

------- Comment #5 from jakub at gcc dot gnu dot org  2010-01-13 17:38 -------
The difference between C and C++ FE is just r138140, i.e. the && !TREE_PUBLIC
check.
Just try
extern void bar (void);
static int foo (void) __attribute__ ((__noreturn__, __used__));

static int
foo (void)
{
  while (1)
    bar ();
}

which warns both in C and C++.  I guess we should just add !TREE_THIS_VOLATILE
(fndecl) check to both C and C++ FE.
