Disable loop-reordering/ loop-interchange

[Paul_S_]

Hello, is it possible to disable loop-reordering/ loop-interchange while compiling with -O3? Thank you, Paul

I haven't seen a supported (publically documented) option for this specific purpose.  #pragma distribute point may have such an effect, probably between the loops you don't want swapped.  #pragma omp often suppresses loop interchanges.
