Bug ID: 77674
Summary: ICE in binds_to_current_def_p with
-fkeep-inline-functions
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ipa
Assignee: unassigned at gcc dot gnu.org
Reporter: bernds at gcc dot gnu.org
Target Milestone: ---
Testcase:
typedef struct { } __fsid_t;
typedef unsigned long int pthread_t;
extern "C" {
extern __inline __attribute__ ((__gnu_inline__)) int pthread_equal (pthread_t
__thread1, pthread_t __thread2) throw () {
}
}
typedef pthread_t __gthread_t;
static __typeof (pthread_equal) __gthrw_pthread_equal __attribute__
((__weakref__ ("pthread_equal")));
static inline int __gthread_equal (__gthread_t __t1, __gthread_t __t2)
{
return __gthrw_pthread_equal (__t1, __t2);
}
Command line (with a normal x86_64-linux compiler):
./cc1plus red4.ii -fpreprocessed -O2 -fkeep-inline-functions -quiet
And the crash:
_ZL21__gthrw_pthread_equalmm/1 (int __gthrw_pthread_equal(pthread_t,
pthread_t)) @0x7f30053f8170
Type: function definition analyzed alias transparent_alias weakref
Visibility: weak
