I am confident in the correctness of the tests I wrote for overflow for C (gcc.dg/overflow-warn-[1234].c). This doesn't necessarily mean the present mixture of ways of indicating that an expression of integer constants is not an integer constant expression (for whatever combination of reasons involving overflow, division by zero, out-of-range shifts, etc.) is the best implementation approach.
