Segher Boessenkool <segher at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |segher at gcc dot gnu.org --- Comment #3 from Segher Boessenkool <segher at gcc dot gnu.org> --- Since people still make this mistake, perhaps we need to make people more aware of this fact in the documentation? "The memory argument to vec_ld and vec_st has to be 16-byte aligned", something short like that. If people see it often enough it will finally click. Carl, can you add something maybe? In some place you would have seen it :-)
