Hi @franferrax ,
I couldn't find the use of abs in jdk11u in superword.cpp. For the safer side I have removed the use of abs and added the traditional way of doing the same. I have pushed the new code change and the testing for hotspot/jtreg is successful on aix-ppc didn't found any related failures. 
Thanks,
Varada
