70 * bitfields, and by a series of [dword offset, bit mask, bit shift]
71 * definitions.
72 * The target should use the struct def, for simplicitly and clarity,
73 * but the host shall use the bit-mast + bit-shift defs, to be endian-
74 * neutral. Specifically, the host shall use the get/set macros built
