Now that it needs to be exported in a public header (Valgrind.h) it should be prefixed to avoid collision with other projects. Add it to llvm-config.h as well.

2011-11-27Prevent rotating the blocks of a loop (and thus getting a backedge to beChandler Carruth
fallthrough) in cases where we might fail to rotate an exit to an outer loop onto the end of the loop chain. Having *some* rotation, but not performing this rotation, is the primary fix of thep performance regression with -enable-block-placement for Olden/em3d (a whopping 30% regression). Still working on reducing the test case that actually exercises this and the new rotation strategy out of this code, but I want to check if this regresses other test cases first as that may indicate it isn't the correct fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145195 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-27Take two on rotating the block ordering of loops. My previous attemptChandler Carruth
was centered around the premise of laying out a loop in a chain, and then rotating that chain. This is good for preserving contiguous layout, but bad for actually making sane rotations. In order to keep it safe, I had to essentially make it impossible to rotate deeply nested loops. The information needed to correctly reason about a deeply nested loop is actually available -- *before* we layout the loop. We know the inner loops are already fused into chains, etc. We lose information the moment we actually lay out the loop. The solution was the other alternative for this algorithm I discussed with Benjamin and some others: rather than rotating the loop after-the-fact, try to pick a profitable starting block for the loop's layout, and then use our existing layout logic. I was worried about the complexity of this "pick" step, but it turns out such complexity is needed to handle all the important cases I keep teasing out of benchmarks. This is, I'm afraid, a bit of a work-in-progress. It is still misbehaving on some likely important cases I'm investigating in Olden. It also isn't really tested. I'm going to try to craft some interesting nested-loop test cases, but it's likely to be extremely time consuming and I don't want to go there until I'm sure I'm testing the correct behavior. Sadly I can't come up with a way of getting simple, fine grained test cases for this logic. We need complex loop structures to even trigger much of it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145183 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-27Rework a bit of the implementation of loop block rotation to not rely soChandler Carruth
heavily on AnalyzeBranch. That routine doesn't behave as we want given that rotation occurs mid-way through re-ordering the function. Instead merely check that there are not unanalyzable branching constructs present, and then reason about the CFG via successor lists. This actually simplifies my mental model for all of this as well. The concrete result is that we now will rotate more loop chains. I've added a test case from Olden highlighting the effect. There is still a bit more to do here though in order to regain all of the performance in Olden. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145179 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-27Introduce a loop block rotation optimization to the new block placementChandler Carruth
pass. This is designed to achieve one of the important optimizations that the old code placement pass did, but more simply. This is a somewhat rough and *very* conservative version of the transform. We could get a lot fancier here if there are profitable cases to do so. In particular, this only looks for a single pattern, it insists that the loop backedge being rotated away is the last backedge in the chain, and it doesn't provide any means of doing better in-loop placement due to the rotation. However, it appears that it will handle the important loops I am finding in the LLVM test suite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145158 91177308-0d34-0410-b5e6-96231b3b80d8
