Where to go from here? If we want to clean up some old SPARC code,
then we have learnt that we to test the result on several key platforms.
We also don't want to create slower code, unless the old code is clearly
broken (in more than a hypothetical way).
For the 64bit case, it is safe to assume

Where to go from here?
Please run make -k in that tarball I posted for you last night, it's
very important.
None of what's happening makes any sense, and we can't make wise decisions
about how to proceed until we

We may well put data in the text segment rather than rodata to allow for
plainer code.
At least in theory, there should be little difference. PC-relative

I use rd %pc here, since moving forward that's what we're going to
use.
I checked in something similar, and also updated the other sparc64 files
to use rd %pc.
I tried to look into doing something like:
L(pc):rd %pc, %g2

Arrg, I didn't actually make a T3 simulated build.

Accomodating a negative offset means using sethi+xor with the
%hix22() and %lox10() relocs, which gets us potentially right back
into the area where we could hit Solaris
Let's take care of this while it's still fresh in our minds.
