Hi all,

Here's a proposed summary of the changes in the AArch64 backend for GCC 6.
If there's anything I've missed it's purely my oversight, feel free to add
entries or suggest improvements.

For me, I'm mostly happy with the wording below (I've tried to be
helpful inline). But I'm not as conscientious at checking grammar as others
in the community. So this is OK from an AArch64 target perspective with
the changes below, but wait a short while to give Gerald or Sandra a chance
to comment.

I haven't done a careful review of the whole section of existing text, but I did notice a few things in text not being touched by this patch:

+     <li>
         The new command line options <code>-march=native</code>,

s/command line options/command-line options/

         <code>-mcpu=native</code> and <code>-mtune=native</code> are now
         available on native AArch64 GNU/Linux systems.  Specifying
         these options will cause GCC to auto-detect the host CPU and

s/will cause/causes/

         rewrite these options to the optimal setting for that system.

-       <code>-fpic</code> is now supported by the AArch64 target when generating
+       <code>-fpic</code> is now supported when generating
         code for the small code model (<code>-mcmodel=small</code>).  The size of
         the global offset table (GOT) is limited to 28KiB under the LP64 SysV ABI
         , and 15KiB under the ILP32 SysV ABI.

Move the comma directly after "ABI", not separated by newline and whitespace.
