How should we set this? Via a configure check or based on compiler
version macros?
How about:
#if __ghs__
+// Define the macro for those compilers that would complain about
+// missing return statements in non-void functions.
+# define VSIP_IMPL_UNREACHABLE_RETURN(expr) return expr;
+#else
+# define VSIP_IMPL_UNREACHABLE_RETURN(expr)
+#endif
We should add a comment with our current knowledge of compiler state:
// GCC: doesn't care
// Intel C++: complains about unreachable returns
// GreenHills: complains about missing unreachable returns
