Hi Shachar,
Interesting problem. Here are some thoughts:
Can you control the level of optimization used by the customer?
Does -O0 create identical object code?
Havn't tested yet, but my gut feeling is "yes".
What are the differences in code? Perhaps they're related to the
different paths? (If the lengths of the paths are different, and
they're stored somewhere in the object code, that'll change the
results)
The question is why should identical source code produce different
paths when compiled with the same compiler?
If the absolute path is included (I think -g does that). The mount
point in the two environments may be called differently.
That's why I'm using objdump -d, which does not print the source files,
and is path location agnostic. In essence, I'm comparing just the actual
assembly produced.
