I mean… I don’t have a power device to be able to look and help you. I do note that there’s a lot of bitmath going on in those functions that it wouldn’t surprise me if it turns out to be your problem. But otherwise you’re just going to need to step through what the optimized and non-optimized versions of this function are doing, and try to understand why they’re coming to a different answer.
@alexmiller I have commented out ‘add_subdirectory(bindings)’ line in CMakeLists.txt for building FDB on ppc64le.
Is it have any effect on tests results?
Bindings are for languages other than C/C++, such as Ruby, Python, Java. So commenting out those won’t affect your test results.
