For C, it is definitely expected within the front end that anything that is an integer constant expression is an INTEGER_CST and that a NOP_EXPR wrapping an INTEGER_CST is something folded to an integer constant that is neither an integer constant expression nor can appear in one.
Right, but that doesn't apply to the C++ front end, which does additional folding at the point where we require a constant expression in order to handle constexpr.
