From: Wang Nan
Date: Fri Nov 06 2015 - 08:50:26 EST


This patchset is based on Arnaldo's perf/core.

Previous version can be found from [1].

Patch 1/7 - 4/7 are error message related patches.

Patch 5/7 - 7/7 are testing related patches.

v1 -> v2:

- Use enum for error code.

- Eliminate for-loop, directly get error message from array using
array index.

- Classify error reason of program loading failure.

- Improve message when version mismatching.
