...uot;wow". I've been looking through the analyses and passes code and have no clue what may be able to make such great optimizations -- I am really impressed by the derivation power of this. Any clue what can trigger such optimizations (I am totally new to llvm code...)? Cheers, Juliusz Sompolski

...mula * unrolling such polynomial-like expressions into a constant time formula, and discarding the loop at all. Even though it can perform such complicated tricks on one loop, it never unrolls two nested loop into a constant even in a simple case. Is there a way to make it do so? Cheers, Juliusz Sompolski

...%6 = mul nsw i32 %5, %4 %7 = mul nsw i32 %4, %4 %8 = sub i32 %6, %7 store i32 %8, i32* %scevgep5, align 4, !tbaa !0 It is interesting, that I get better compilation output when inputting clang with worse input source (creating redundant temporary tables on stack). Cheers, Juliusz Sompolski
