Hi Carrot,

Sorry if this has already been reported, but the patch breaks bootstrap
of arm-linux-gnueabi (or cross builds with --enable-werror).  The problem
is that this...

uses a statement expression -- i.e. ({ code; result; }) -- which is
a GNU extension.

I suppose a simple fix would be to put the code into an arm.c function.


Thank you for the report, I will add this fix to the second part of the patch.

It would be worth unbreaking bootstrap as a separate patch and not conflating it with a different set of improvements.
