------- Comment #4 from aldot at gcc dot gnu dot org 2008-01-31 14:47 -------
Smaller testcase:
-----------------------------------
$ cat pr35034-1.c
/* PR 35034 - fails to mangle function names for different TUs. */
/* { dg-do compile } */
/* { dg-options "-combine -O0" } */
/* { dg-additional-sources pr35034-2.c } */
typedef int int_t;
static void
size_of_encoded_value (void)
{
};
extern int pthread_once (int_t *__once_control,
void (*__init_routine) (void));
static __typeof(pthread_once) __gthrw_pthread_once __attribute__
((__weakref__("pthread_once")));
-----------------------------------
$ cat pr35034-2.c
void size_of_encoded_value (void)
{
};
-----------------------------------
