Hi,
Can you review the code changes and send in your comments or suggestions?
Patch Inlined:
---------------
The latest clang is emitting strx forms for strings earlier it was
emitting strp form. Due to this change, the readelf test case is failing,
fixing the regular expression in the test case fixes the issue. Similar
behavior is seen with addresses and fixed that as well.

The adjustments are okay, but please make at least one of title or
subject say which specific testcase it is that is failing. Feel
free to apply with the text adjustment.

Thanks Jan,
I made the changes you have suggested. Can I go ahead and merge the code changes ?
