Thanks a lot Stefan, that should completely explain my issues.
-fno-strict-aliasing -fwrapv for gcc
So, that means that you would get better performance if you applied on Python v2.7 what Python v3.5 did about Py_SIZE(x) .
However, there are probably other places where the aliasing issue still appears in v2.7 .
Hummm I'll use -qalias=noansi with XLC and see what happens. |
