Not all of them, say INT_MIN can't be negated.
Though,
int
foo (int n)
{
int i, d;
for (i = 0, d = 0; i < n; i++)
d -= -__INT_MAX__ - 1;
return d;
}
doesn't trigger it. And for constants I thought it would be better to
just fold it immediately.

Is make_temp_ssa_name (TREE_TYPE (rhs), NULL, NULL) preferrable over just
make_ssa_name (TREE_TYPE (rhs), NULL); ?
