sse2 is a intel cpu extention it is only available on x86 https://en.wi
kipedia.org/wiki/SSE2 it is also not available on all x86 cpu's the
code is question seems to have a bug in its design if it is relying on
the behavior, some supported 32 bit hardware will not run the code.
Taking advantage of such instructions should be a runtime decison and
on other arches the code should have a path that will work. https://fed
oraproject.org/wiki/Packaging:Guidelines#Architecture_Support lays out
the policy for excluding arches, please be sure to file the appropriate
bugs. It would be good to work with upstream to look into supporting
all architectures. The architecture teams can help you in getting
things working.
