I have a feeling we discussed this already, but I don't remember what was the conclusion.
Was exposing debug registers to the user a conscious choice? Other OSes don't actually do that. Neither does gdb, afaict...
In think that allowing the user to see dr contents is a good idea -- allows him to check what the debugger has done. I'm not convinced about the writing aspect though -- seems like an easy way to confuse the debugger and make it crash...

+# XFAIL: system-windows
+# REQUIRES: native && (target-x86 || target-x86_64) && can-set-dbregs
+# RUN: %clangxx_host -g %p/Inputs/x86-db-read.cpp -o %t
Who sets `can-set-dbregs` ?
