Hi, Vladimir,
Apparently the issue that David mentioned has already been fixed earlier:

...
* lra-constraints.c (curr_insn_set): New.
...
(process_alt_operands): Use it. Use #if HAVE_ATTR_enabled instead
of #ifdef. Add code to remove cycling.

However, such change is only applied on trunk but not on 4.8 branch.
Since 4.8 branch is still open and this issue seems to be a bug,
perhaps it is a good idea to backport this part.
What do you think? :)
I guess it is worth to do. It should be safe so no any objections for this.
