Hi Timo,
There are no changes in the logic, it's just to avoid a crash
("internal compiler error: in vect_transform_stmt, at
tree-vect-stmts.c:4887"). It's only in GCC versions 4.6.x.
Incidentally, was it through an oversight, or with a design, that
KiConvertToGuiThread (one which is in trap.s, committed in r52509),
does not save/restore EBX?
