288 example, an i386 extended-precision floating point value really
289 only occupies ten bytes, but most ABI's declare its size to be
290 12 bytes, to preserve alignment. A `struct type' representing
291 such a floating-point type would have a `length' value of 12,

297 and such, meaning it must be in units of host bytes. Various
298 other places expect they can calculate addresses by adding it
299 and such, meaning it must be in units of target bytes. For
300 some DSP targets, in which HOST_CHAR_BIT will (presumably) be 8
301 and TARGET_CHAR_BIT will be (say) 32, this is a problem.
302
303 One fix would be to make this field in bits (requiring that it
304 always be a multiple of HOST_CHAR_BIT and TARGET_CHAR_BIT) ---
305 the other choice would be to make it consistently in units of
