Numerous people have pointed out that there exist tools to produce instructions counts, which would aid in the counting of integer / floating point operations. This is true (I have written a quick-and-dirty instruction counter myself, using ptrace), but such tools tend to be system/architecture dependent (even my single stepper didn't work on SPARC), cumbersome to use, and report with different granularity. For instance, what exactly would constitute a floating point operation, and how would the various tools report it? Benchmarks should be self-contained. Relying on extra system dependent hardware or software to analyze the results of a run will only serve to guarantee apples-to-oranges comparisons.
