#1 No profiling of optimized code???

No

I found it a very strong limitation that fnccheck
doesn't work at all with any kind of optimization
turned on. This is a real problem, IMHO, particularly
for a compiler like GCC, whose unoptimized code is
almost unbearably bad. Profiling such unoptimized code
may give results biassed enough to be unusable.

So, please, could we add support for profiling
optimized code, too?

    Please indicate the version of fnccheck you are
    talking about, as many versions exist.

    By the way (at least for the V3.0.* and the V2.0)
    it is possible to use -O option (even -O9 :o)
    without any problem. I try it for the test/ examples
    in V3.0.* and it runs without any problem, and the profile
    data files are correct and readable by the profile
    analyzer.
