Actually, it does for %g and %o registers. See section 2.1.1.
I've thought before about how to adjust the __sparcv8plus__ TCG
to use full 64-bit registers and operations when required, but
have not yet gotten around to it.
All of sparc, mips, ppc, and s390 have a mode with 32-bit pointers
running on a machine with 64-bit registers and operations available.
Unfortunately the hppa linux kernel doesn't save the full 64-bit
register on interrupt, so we're strictly limited to pa1.1 there,
even when running on a pa2 machine.
Something for the future...
