/* Basic tests for BTF bitfields.
The structure containing bitfield members should be marked with KIND_FLAG=1
The bitfield member offsets should be encoded as:
(bit_size << 24) | bit_offset
- (0xa << 24) | 0x20
- (0x7 << 24) | 0x2a
- (0x13 << 24) | 0x40 - note that this is aligned to 0x40.
- (0x13 << 24) | 0x31 - in case structures are packed. */
