--- Comment #8 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
> Well - when I build the test -O0,O1,Os it passes.
Confirmed when running the test suite. However the following reduced test
/* { dg-do run { target hppa*-*-hpux* *-*-linux* *-*-gnu* powerpc*-*-darwin*
*-*-darwin[912]* } } */
/* { dg-require-effective-target sync_long_long_runtime } */
/* { dg-options "-fexceptions -fnon-call-exceptions -O2" } */
/* Verify that the builtin functions are correctly marked as trapping
when using -fnon-call-exceptions. */
#include <stdlib.h>
#include <signal.h>
typedef int ditype __attribute__ ((mode (DI)));
#define FN(IDX, RET, CALL) \
static RET f ## IDX (void *p) __attribute__ ((noinline)); \
static RET \
f ## IDX (void *p) \
{ \
return CALL; \
} \
static void \
t ## IDX () \
{ \
try \
{ \
f ## IDX(0); \
} \
catch (...) \
{ \
return; \
} \
abort(); \
}
FN(18, void, (__atomic_clear((ditype*)p, __ATOMIC_SEQ_CST)))
static void
handler(int)
{
sigset_t clear;
sigfillset (&clear);
sigprocmask (SIG_UNBLOCK, &clear, NULL);
throw 0;
}
int
main ()
{
signal (SIGSEGV, handler);
signal (SIGBUS, handler);
t18();
exit(0);
}
fails with -O1, but not with -O0 (-m32 and -m64).
