Ok, I have that fixed locally at the place of the patch but I wonder if
initial_condition () shouldn't return for example
1ul for (unsigned long) { 1, +, 1 }_1
and
(int) i_2 for (int) { i_2, +, 1 }_1
and further (for short i_2)
i_2 for (short) { (int) { i_2, +, 1 }_2, +, 1 }_1
? Can the latter two happen all? Is it even correct to talk about a
general initial condition in this case? Consider
{ { 1, +, 1 }_2, +, 1 }_1
initial_condition will return 1 for the chrec even though that is not
correct because the initial condition is not constant in loop 1.
I suppose I'd only see that if instantiating the chrec at the point
where I placed the fix? So I really only see at most a single outer
conversion around the chrec?
