   1 /* BTF generation for variables with removed type.

   3    BTF does not support floating point types, so no representation for the type
   4    'float' will be emitted. In this test, we check to also ensure that the
   5    variable 'bar' is not emitted, as it references a type that is not supported
   6    in BTF.  */
