- gradstudent 11y agoYeah, I came to post the same thing. What /exactly/ is this code doing that makes turning off optimisations faster? What does the assembly look like, with -ffast-math and without? Can these differences be used to draw a hypothesis, one that could be tested empirically? Despite the title, which promises an article with some interesting technical depth, I just don't feel like I learned anything. On the whole the piece comes off like a glib anecdote; lazy and not very informative.
