[Bug c/32493] gcc-20070624 fails linux-kernel due to changed gcc-inlining

["rguenth at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #2 from rguenth at gcc dot gnu dot org  2007-06-27 14:17 -------
Reduced testcase:

static inline __attribute__((always_inline)) void __check_printsym_format(const
char *fmt, ...)
{
}
static inline __attribute__((always_inline)) void print_symbol(const char *fmt,
unsigned long addr)
{
 __check_printsym_format(fmt, "");
}
void do_initcalls(void **call)
{
   print_symbol(": %s()", (unsigned long) *call);
}

Now, if we make use of the passed variable arguments we would have hit

t2.i: In function '__check_printsym_format':
t2.i:2: sorry, unimplemented: function '__check_printsym_format' can never be
inlined because it uses variable argument lists

that we now hit this even if the varargs are unused is ... unfortunate.
