            Bug ID: 106077
           Summary: Invalid IPA-SRA with non-call exceptions
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ipa
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hubicka at gcc dot gnu.org
                CC: marxin at gcc dot gnu.org
  Target Milestone: ---

Compiled with -O2 -fno-ipa-cp we make t() to trap instead of calling
non-call-exception from wrap

short e,f;
static __attribute__ ((noinline))
int a(int *b)
{
        return *b;
}
static __attribute__ ((noinline))
__attribute__ ((optimize("non-call-exceptions")))
int wrap(int *b,int e, int f)
{
        e/=f;
        return a(b)+e;
}

int
t()
{
        return wrap(0,1,0);
}
