--- Comment #37 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
just checking even the basic default examole square() with godbolt.org shows
that everything is covered, with the exceotion that reg 31 appears to be used
by convention as a Stack Pointer (SP).

to cover that possibility it would be good to remap Compressed RA=0b111 to
RA=0b11111 at least for LD/ST, and also to make sure that the commonly used
regs from ppc64 ABI are smack in the reduced range.
