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

269 about machines whose bytes aren't eight bits long, or who don't
270 have byte-addressed memory. Various places pass this to memcpy
271 and such, meaning it must be in units of host bytes. Various
272 other places expect they can calculate addresses by adding it
273 and such, meaning it must be in units of target bytes. For
274 some DSP targets, in which HOST_CHAR_BIT will (presumably) be 8
275 and TARGET_CHAR_BIT will be (say) 32, this is a problem.
277 One fix would be to make this field in bits (requiring that it
278 always be a multiple of HOST_CHAR_BIT and TARGET_CHAR_BIT) ---
279 the other choice would be to make it consistently in units of
280 HOST_CHAR_BIT. However, this would still fail to address
