I noticed that sometimes GCC generates:
_8 = memcpy (ret_6, s_2(D), len_4);
_8 = memcpy (ret_6, s_2(D), len_4);
memcpy (_17, buffer_12(D), add_16);
memcpy (_17, buffer_12(D), add_16);
memcpy (_25, _28, _27);
memcpy (_25, _28, _27);
memcpy (_39, buffer_2, len_4);
memcpy (_39, buffer_2, len_4);
memcpy (_16, &fillbuf, pad_1);
memcpy (_16, &fillbuf, pad_1);
...
