Okay. My question was along the lines of "is this a sane default or am I wandering into a minefield," your answer is pretty much what I was looking for. > Some of the current optimizations are so advanced and specific for each particular bit of code that it might not good to generalize from those output. If only it were possible for the compiler to concisely describe its "workings-out". I imagine compilers can generate trace information, but it's probably pages long. > I remember ICC generating different (but similar) code for each Intel CPU generation. I suppose it has to do with the decoder limitation (4-1-1-1, 4-2, 2-2, etc.) and exhausting execution port usage... That's amazing. Definitely keeping that in mind, thanks!
