[USRP-users] E310 RFNoC and Vivado 2015.2 Build Problem

>From the announcement in September it seemed like rfnoc-devel has been
updated to Vivado 2015.2, so I just upgraded. Now I am having difficulty
making E310_RFNOC from scratch (it worked fine under 2014.4). The problem
seems to be related to the divide_int16_int32 IP. Relevant error messages
from the log are below.

Seems like these errors occur when IP has been generated with an older
version of Vivado. The file usrp3/lib/ip/divide_int16_int32.xci indicates
it was made with 2014.4 - does it still need to be updated to 2015.2? If
not, any suggestions to get this working?
