Chandler Carruth b9cb5b19d9 [unroll] Change the other worklist in the unroll analyzer to be a set ... vector. In addition to dramatically reducing the work required for contrived example loops, this also has to correct some serious latent bugs in the cost computation. Previously, we might add an instruction onto the worklist once for every load which it used and was simplified. Then we would visit it many times and accumulate "savings" each time. I mean, fortunately this couldn't matter for things like calls with 100s of operands, but even for binary operators this code seems like it must be double counting the savings. I just noticed this by inspection and due to the runtime problems it can introduce, I don't have any test cases for cases where the cost produced by this routine is unacceptable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@229059 91177308-0d34-0410-b5e6-96231b3b80d8		2015-02-13 04:27:50 +00:00
