284 such a floating-point type would have a `length' value of 12,

287 There's a bit of a host/target mess here, if you're concerned
288 about machines whose bytes aren't eight bits long, or who don't
289 have byte-addressed memory. Various places pass this to memcpy
290 and such, meaning it must be in units of host bytes. Various
291 other places expect they can calculate addresses by adding it
292 and such, meaning it must be in units of target bytes. For
293 some DSP targets, in which HOST_CHAR_BIT will (presumably) be 8
294 and TARGET_CHAR_BIT will be (say) 32, this is a problem.
295
296 One fix would be to make this field in bits (requiring that it
297 always be a multiple of HOST_CHAR_BIT and TARGET_CHAR_BIT) ---
298 the other choice would be to make it consistently in units of
