He got this by comparing a -O0 run with a -02 run and then dividing, but the obvious problem with this is that even if a modern compiler is run with -O0 it&apos;s probably going to be in effect optimizing a lot just by all the architectural choices and default code generation. It would be interesting to see if one could take a more recent C compiler, say late &apos;70s and compare it to a heavily optimizing GCC run, and answer the question: how much have C compilers improved over the last 30-40 years?</text></comment>
