/* The return-value jump tables in linux.S and hpux32.S are indexed by

   return type it does not handle explicitly -- including FFI_TYPE_COMPLEX and
   the 128-bit integer types FFI_TYPE_UINT128/FFI_TYPE_SINT128 -- falls through
   to the default case and is mapped to FFI_TYPE_INT, so cif->flags never
   exceeds FFI_TYPE_COMPLEX and the existing tables remain sufficient.  Bump
   FFI_PA_TYPE_LAST to the current FFI_TYPE_LAST once you have confirmed any
   newly added generic type is likewise handled (or the tables extended).

   FFI_TYPE_VECTOR (18) is likewise not reached here: PA does not define
   FFI_TARGET_HAS_VECTOR_TYPE, so ffi_prep_cif_core rejects any vector
   signature with FFI_BAD_TYPEDEF before machdep runs.  Bumping the tripwire
   past it is therefore safe.  */
