The bug is not in the applications, since the application in question
(latency) is running fine on other platforms, including ARM ones. The
bug is in your port.

diff -u
git diff does it just fine. And if you do not use git, you should.

I do not think there is a general documentation on how to debug code. It
really depends on what code you debug, and what are the symptoms you
observe.
