What's the status of this? Did the GCC proposal go anywhere? I'd be happy to see this move forward if you're also pushing it on the GCC side.

Comment at: clang/lib/CodeGen/CGStmt.cpp:2077
+  // which one to emit.
+  // FIXME: Should we add one additional level of granulariy, where the compiler
+  // can forgive the user, if they mention the same register to be used through
I don't think the FIXME seems useful. I don't see any reason why anyone should validly use both at the same time.
