   As this patch has got approve from GCC, is it OK to install into 
binutils-gdb master?

   My understanding is "include/dwarf2.def" is shared between GDB and 
Binutils.

   This patch and the described AArch64 DWARF proposal has got GDB ack 
from https://sourceware.org/ml/gdb-patches/2016-11/msg01008.html which, 
from my understanding, is a conditional approval given there is follow 
up GDB patches on multiplexing DW_CFA_GNU_window_save.

   This patch still need Binutils approval.

   Thanks.
