--- Comment #9 from Mark Wielaard <mark at klomp dot org> ---
P.S. Note that the actual bit offset for the different attributes is defined
differently:

DW_AT_bit_offset: The bit offset attribute describes the offset in bits of =
the
high order bit of a value of the given type from the high order bit of the
storage unit used to contain that value.

DW_AT_data_bit_offset: the value is an integer constant that specifies the
number of bits from the beginning of the containing entity to the beginning=
 of
the data member.

DWARF5 has some example for big and little endian in D.2.8 C/C++ Bit-Field
