OK, thanks for info. I do not think I have those available.

One can test the number of registers in singlethreaded testcase and then run
the real test with multithreaded program.

A testcase would be nice, for example now the changes in
archer-jankratochvil-watchpoint3 and pre-requisite of non-stop compatibility
of hw watchpoints mean a lot of hw watchpoints rewrite in ppc-linux-nat.c.

But if you are not going to write a testcase then I find it OK for both HEAD
and 7.5.

Thanks,
