------- Additional Comments From pinskia at gcc dot gnu dot org 2005-04-26 19:51 ------- The problem comes from dce but the problem is that IV OPT is making the pointer as "unsigned int *", because the field's type is just "unsigned int[]" but since the orginal type of the struct is volatile, we don't have a vop as it is volatile store. And since IV opts just copies the vops and not run aliasing (which right now causes a different issue on 4.0 branch), we don't get a vop.
