------- Comment #3 from pinskia at gcc dot gnu dot org 2008-08-31 01:57 -------
Here is a short reduced testcase:
void f(int);
inline void _M_reset (int *a) throw()
{
f (*a);
}
bool _M_finished();
int _M_curr_index;
void _M_allocate_single_object()
{
if (__builtin_expect (_M_finished(), false))
{
_M_reset(&_M_curr_index);
_M_reset(&_M_curr_index);
}
}
So what is happening is that we are not inlining as the we find the basic block
containing the two _M_reset is cold (via the __builtin_expect) so we decide to
do IPA-CP instead as we have two calls to that function with the same argument.
We create an IPA-cp clone of the function of _M_reset, mark it as a local
function but don't clear DECL_WEAK. I will see what we can do for this decl
soon.
