-/* For power and powerpc we want an inline ldu/stu/bdnz loop for copying.
-   On ppc630 for instance this is optimal since it can sustain only 1 store
-   per cycle.
-
-   gcc 2.95.x (powerpc64 -maix64, or powerpc32) doesn't recognise the "for"
-   loop in the generic code below can become ldu/stu/bdnz.  The do/while
-   here helps it get to that.
-
-   In gcc -mpowerpc64 mode, without -maix64, __size seems to want to be an
-   mp_limb_t to get into the ctr register, and even then the loop is a
-   curious ldu/stu/bdz/b.  But let's not worry about that unless there's a
-   system using this.  An asm block could force what we want if necessary.
-
-   xlc 3.1 already generates ldu/stu/bdnz from the generic C, and does so
-   from this loop too.  */
