[Bug c/19976] integer division by zero in subexpression should be overflow

[manu at gcc dot gnu dot org]

------- Comment #9 from manu at gcc dot gnu dot org  2007-03-11 00:31 -------
I tried setting TREE_OVERFLOW on a new node created from the zero of the
division by zero and then replacing the zero in 1/0 by this new node. It didn't
work, it seems that somehow the node that represents the result of 1/0 is built
in some way that ignores TREE_OVERFLOW.
