212
213 There may be registers from different PowerPC variants assigned the

215 numbers in the context of a particular variant, so it's not
216 ambiguous.
217
218 We need to deviate from the naming pattern when variants have
219 special-purpose registers of the same name, but with different
220 numbers. Fortunately, this is rare: look below to see how we
221 handle the 'tcr' registers on the 403/403GX and 602. */
