RTEMS for SPARCv9?

[Tito Costa]

hi guys!

I was wondering if anyone had developed a SPARCv9 version of RTEMS. It 
turns out that erc32 and leon version provided with the latest snapshots 
are targeted to SPARCv7.
Besides the fact that it is a 64-bit architecture, SPARCv9 has deeply 
changed with respect to register window management, state and control 
registers, trap management, privileged/user level switching; most of 
assembly routine for interrupts handling, syscalls and scheduling would 
have to be rewritten.

thank you
