The GCC manual mentions a -a option that generates code to
profile basic blocks. Unfortunately my program complains that 
the file "tt2.d" does not exist, when compiled with -a.
The source file is tt2.c.
I understand that no program exists that interpretes this profiling data.

Has this option been tested at all?
What does above error message mean?
Is there any information about the format of the generated profiling
data?

As I need a basic block profiler, I would eventually write a program
that interpretes this data, if it is feasible,
and I am grateful for any hint.
