This wasn't meant to be documented, and it was not expected that anyone uses
it.
The more basic constraints ("wa", "d", "v") are easier to use and more correct.

See above. Those work in older compilers, too.

Old POWER is RIOS1. From the year 1990. (And RIOS2, from 1993). It has a
different assembler syntax and somewhat different semantics than the later
PowerPC. All machines you name are PowerPC. Which later was rebaptised to
"POWER Architecture" or "Power ISA" etc. "Old POWER" some of us use to refer
to the ancient systems.
[ "ws" needs at least a Power7, btw. ]
