Hi, devs! I encounter some problems(which is similar to(https://github.com/harvard-acc/gem5-aladdin/issues/35. The message looks like an error not a waning) when i use gem5-aladdin with test_loop_sampling test

Error

Overlapping array address ranges can lead to incorrect behavior, such as DMA nodes trying to access the wrong arrays, ACP accessing the wrong memory, etc. Please check your Aladdin configuration file and the mapArrayToAccelerator() calls to verify that they are correct.
Global loop pipelining is not ON.
 Current power model supports trig functions running at 10 ns. 
 Cycle time: 2 is not supported yet. Use 10ns power model instead.

How to reproduce

1. get docker from docker pub
2. docker run image
3. python2.7 `which scons` build/X86/gem5.opt
4. cd /workspace/gem5-aladdin/src/aladdin/integration-test/with-cpu/test_loop_sampling
5. sh run.sh

Don't worry about it. The overlap detection logic has been broken for a long time but we just never got around to fixing it...
