// This test makes sure that the enum declarations in section "5. Enum
// declarations" of the SVE ACLE [1] are not presented as typedefs in
// `arm_sve.h`. It does so by creating a typedef'd struct with the
// same identifier as the one defined in `arm_sve.h`, then checking that
// it does not overload the enum defined in `arm_sve.h`.
