How to force the branch target to be 4 byte aligned? Any compiler options to do that? I am using arm A15.

Thank you very much Ronan for getting back to me on this!

Also, we are using a dual core A15 model pre-silicon. The question is why when this happens (slowness of the tight loop), the timer register slows down too? Ultimately, this function is waiting for a certain amount of timer increments to pass.  If there is efficiency lost in few cpu cycles, it seems like it should be a don’t care?  We’re looping around a *lot* of times just waiting for the timer to expire.

What we’d really be asking is “does this alignment inefficiency cause the ARM fast model to take inordinate amounts of time to simulate?"

Hello again, from a simple test I cannot replicate such behavior.

It is probably best to raise an official support case from the support menu above. You may need to share the code as well as the system you are running to help investigate thoroughly.

Okay, I will open an official case. Thank you very much Ronan!

Isn't this one official? I opened this case through the menu -> ...
