Counting FLOPS

[Rouben Rostamian]

How does one count the number of floating point operations (flops) during
the execution of a C program?  I guess it is possible to trace manually all
loops and function calls and iterations and recursions, etc., and add them
up, but that will easily gets out of hand for a half-way complicated program.
Are there automatic tools for doing this?

I am primarily interested in a solution which will work under RISC Ultrix,
if that matters.
