* split dom frontier handling stuff out to its own DominanceFrontier header,Chris Lattner2011-01-02
| | | | | | | | so that Dominators.h is *just* domtree. Also prune #includes a bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122714 91177308-0d34-0410-b5e6-96231b3b80d8
* Move Value::getUnderlyingObject to be a standaloneDan Gohman2010-12-15
| | | | | | | | function so that it can live in Analysis instead of VMCore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121885 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | functions of ScalarEvolution, in preparation for memoization and other optimizations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119562 91177308-0d34-0410-b5e6-96231b3b80d8
* Begin adding static dependence information to passes, which will allow us toOwen Anderson2010-10-12
| | | | | | | | | | perform initialization without static constructors AND without explicit initialization by the client. For the moment, passes are required to initialize both their (potential) dependencies and any passes they preserve. I hope to be able to relax the latter requirement in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116334 91177308-0d34-0410-b5e6-96231b3b80d8

* Define placement new wrappers for BumpPtrAllocator andDan Gohman2010-03-18
| | | | | | | | RecyclingAllocator to allow client code to be simpler, and simplify several clients. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98847 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | s/errs/dbgs/g except for certain special cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92042 91177308-0d34-0410-b5e6-96231b3b80d8

* SIV/MIV classification for LDA.Andreas Bolka2009-08-07
| | | | | | | | | | LoopDependenceAnalysis::getLoops is currently O(N*M) for a loop-nest of depth N and a compound SCEV of M atomic SCEVs. As both N and M will typically be very small, this should not be a problem. If it turns out to be one, rewriting getLoops as SCEVVisitor will reduce complexity to O(M). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78394 91177308-0d34-0410-b5e6-96231b3b80d8
* Simplify the ZIV tester to the max.Andreas Bolka2009-08-06
| | | | | | As suggested by Nick Lewycky. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78277 91177308-0d34-0410-b5e6-96231b3b80d8
* ZIV tester for LDA.Andreas Bolka2009-08-05
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78157 91177308-0d34-0410-b5e6-96231b3b80d8
* Restrict LDA to GEPs with the same pointer offset.Andreas Bolka2009-08-05
| | | | | | | We can not simply apply ZIV testing to the pointer offsets, as this would incorrectly return independence for e.g. (GEP x,0,i; GEP x,1,-i). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78155 91177308-0d34-0410-b5e6-96231b3b80d8
* Restrict LDA to affine subscripts.Andreas Bolka2009-08-03
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77932 91177308-0d34-0410-b5e6-96231b3b80d8
* Equal SCEVs of a subscript give rise to dependence.Andreas Bolka2009-07-30
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77570 91177308-0d34-0410-b5e6-96231b3b80d8
* Skeleton for pairwise subscript testing.Andreas Bolka2009-07-29
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77437 91177308-0d34-0410-b5e6-96231b3b80d8
* Simplify LDA-internal interface.Andreas Bolka2009-07-28
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77359 91177308-0d34-0410-b5e6-96231b3b80d8

* Minor factoring, naming and formatting cleanups.Andreas Bolka2009-07-28
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77357 91177308-0d34-0410-b5e6-96231b3b80d8

* Make AliasAnalysis and related classes useDan Gohman2009-07-25
| | | | | | | getAnalysisIfAvailable<TargetData>(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77028 91177308-0d34-0410-b5e6-96231b3b80d8
* Forward-declare raw_ostream.Andreas Bolka2009-07-24
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77014 91177308-0d34-0410-b5e6-96231b3b80d8
* Cache dependence computation using FoldingSet.Andreas Bolka2009-07-23
| | | | | | | | | This introduces an LDA-internal DependencePair class. The intention is, that this is a place where dependence testers can store various results such as SCEVs describing conflicting iterations, breaking conditions, distance/direction vectors, etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76877 91177308-0d34-0410-b5e6-96231b3b80d8
* Minor cosmetics: indentation, formatting, naming.Andreas Bolka2009-07-23
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76839 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin2009-07-14
| | | | | | | | | | This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75640 91177308-0d34-0410-b5e6-96231b3b80d8
* assert(0) -> LLVM_UNREACHABLE.Torok Edwin2009-07-11
| | | | | | | | | | Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75379 91177308-0d34-0410-b5e6-96231b3b80d8
