/* Test BTF generation for non-representable bitfields.
Due to the limitations of BTF, we only have 24 bits in which to store
the bitfield offset (in bits, from the beginning of the struct).
In this test, we construct a structure such that the bitfield will have
an offset so large as to be unrepresentable in BTF. We expect that the
resulting BTF will describe the rest of the structure, ignoring the
non-representable bitfield. */
