--- Comment #11 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
C++17 and later has special new operators, so
typedef int V __attribute__((vector_size (64)));
int *
foo ()
{
return new int ();
}
V *
bar ()
{
return new V ();
}
int *
baz ()
{
return new int[32] ();
}
V *
qux ()
{
return new V[32] ();
}
in C++14 and earlier results in 2 _Znwm calls and 2 _Znam calls, while C++17
and later replaces one of the _Znwm calls with
_ZnwmSt11align_val_t and one of the _Znam calls with _ZnamSt11align_val_t and
asks for 64 byte alignment there.
But I have no idea what std::vector in the end uses and whether it can pass
align_val_t or not.
