I have bootstrapped the toolchain, and have run some preliminary tests on simulate-thread.exp. Everything looks fine.
Andrew, can you check this version out, and make sure everything (testwise) is as expected?
I have merged trunk->cxx-mem-model once again, so I can generate a
master diff to post to the list for the curious. And so we can make
sure there are no spurious changes unrelated to the branch.
