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

308 about machines whose bytes aren't eight bits long, or who don't

311 other places expect they can calculate addresses by adding it
312 and such, meaning it must be in units of target bytes. For
313 some DSP targets, in which HOST_CHAR_BIT will (presumably) be 8
314 and TARGET_CHAR_BIT will be (say) 32, this is a problem.
315
316 One fix would be to make this field in bits (requiring that it
317 always be a multiple of HOST_CHAR_BIT and TARGET_CHAR_BIT) ---
318 the other choice would be to make it consistently in units of
