I don't think this bug is important. It never results in a wrong code generation. It might only change the allocation cost and the cost change in such case is insignificant. Changing int to int64_t would hurt the compilation speed because costs arrays can be quite big and the cost calculation is expensive. I have an experimental branch (ira-select) which contains rewriting all this code, it might solve the problem too. There is a possibility that the new code will be in gcc-9. If the problem exists on the branch I'll work on it. So I believe the bug should be P4 one and we can ignore it for now.
