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