------- Comment #6 from pinskia at gcc dot gnu dot org 2006-11-18 18:05 -------
There are two SSE instructions for loading memory, one that does unaligned
loads and one that does aligned loads. And the default instruction used for
vectors pointers is the aligned one. This is standard SSE way of doing it and
not a GCC specific issue. Most likely because the data is aligned just off by
4 bytes.
