While I'm still with Oracle I have time to work on the rest of my patches,
which pretty much means finalizing gcc toolchain detection thing:
    https://reviews.llvm.org/D35755

It was mostly LGTMed by Aaron and now just waits for somebody to answer the
Linux-related
question on a code touched by my cleanup.

If anybody helps me with access to other Solarii I would be glad to make
sure
this patch works for those other ones as well.

There are many rumors, which I'm not in position to comment, especially the
one about Studio group.
Released Studio products will most definitely be supported as promised.
Some say that future SPARC is dead, and a silent update to oracle public
roadmap hints that:

http://www.oracle.com/us/products/servers-storage/servers/sparc/oracle-sparc/sparc-roadmap-slide-2076743.pdf

(there is no SPARC.next+ there anymore, while you might find it in archived
versions of this doc).
Solaris 11.next is in the roadmap, so most likely Oracle Solaris 11 will be
maintained for a significant period of time.

best regards,
  Fedor.

  But hopefully they can be the basis to get a
