--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
One quite visible change is that D has those stmts that clear the vars before
it is constructed, so e.g. in main:
SR.11_24 = 0;
_12 = SR.11_24;
MEM <uint128_t> [(unsigned char * {ref-all})&nrvo] = _12;
nrvo = nrvo101273 (); [return slot optimization]
instead of C++
nrvo = nrvo101273 (); [return slot optimization]
