Dear GCC people, Greetings! Sorry to bother you with an idiotic question, but I might have misunderstood something rather profoundly. See GCC internals chapter 16.14 "Canonicalization of Instructions". In item #4 of the list of canonicalizations, it is stated: "(plus (mult (neg A) B) C) is canonicalized as (minus A (mult B C))." Now, that looks a bit strange. Does that mean that ((-a) * b) + c) is-equal-to (a - (b * c)) because it doesn't seem that way if I substitute a=3, b=5, c=7 I get ((-3) * 5) + 7) = (-15 + 7) = -8 and (3 - (5 * 7)) = (3 - (35)) = -32. Am I getting something wrong? To be sure, I checked this with my soviet made Elorg 801 LED calculator I bought from a flee-market at the price of one euro. Cheers, Panu
