The new Integrated Register Allocator is now in GCC trunk, and the old allocator is scheduled for removal on or shortly after 25 September. All GCC targets need updating for the new allocator; targets that have not been updated when the old allocator is removed will no longer work and will be added to the deprecation list for GCC 4.4. (After that date target maintainers may remove their targets from the deprecation list as part of the patches updating them for the new allocator; any remaining unconverted targets will be removed from trunk after GCC 4.4 branches along with the other targets deprecated in 4.4.)
I have a patch for Xtensa but I'm still tracking down a problem related to the IRA code. I'm sure I'll get it sorted out soon.
