--- Comment #4 from Drea Pinski <pinskia at gcc dot gnu.org> ---
Note I think this actually was exposed by r16-26-g2d693c1ffd849e.
Before dse3:
MEM[(int32_t *)&vec0] = 0;
After:
MEM <char[2]> [(int32_t *)&vec0 + 2B] = {};
Note the issue is NOT in fre5 but rather execute_update_addresses_taken code.
or maybe it is in this:
rhs = fold_build1 (VIEW_CONVERT_EXPR,
TREE_TYPE (lhs), rhs);
Which for some reason is not folding into 0.
I will look into this more later.
