We have a restriction in x86_64 targets on the no of memory references inside a

Hi Michael,
I am looking into this bug (card 418). Yes this does not occur with LRA.
However we want to fix it since it is in gcc 4.8 and people are using it.
I discussed with Maxim and having a conservative patch to test and check with
GCC community.
Regards,
Venkat.

This support is currently in trunk and not in gcc 4.8
It will be going to gcc4.9 and will be there when Linaro branches to 4.9.
I tested a patch and it worked

Hi Andrew,
I have not started on this task yet.

Thank you for the pointers and people who I can contact. I will take a look and
