* Moved some comments due to the recent refactoring of ObjCARC.Michael Gottesman2013-02-072-5/+4
| | | | | | | | 1. Moved a comment from ObjCARCOpts.cpp -> ObjCARCContract.cpp. 2. Removed a comment from ObjCARCOpts.cpp that was already moved to ObjCARCAliasAnalysis.h/.cpp. llvm-svn: 174581
* Preserve fast-math flags after reassociation and commutation. Update test casesMichael Ilseman2013-02-071-5/+20

* InstCombine: Fix and simplify the inttoptr side too.Benjamin Kramer2013-02-051-13/+8
| | | | llvm-svn: 174438
* Removed explicit inline as per the LLVM style guide.Michael Gottesman2013-02-051-7/+7
| | | | llvm-svn: 174432
* InstCombine: Harden code to work with vectors of pointers and simplify it a bit.Benjamin Kramer2013-02-051-11/+7
| | | | | | Found by running instcombine on a fabricated test case for the constant folder. llvm-svn: 174430
* Loop Vectorizer: Refactor code to compute vectorized memory instruction costArnold Schwaighofer2013-02-051-79/+178
| | | | | | | Introduce a helper class that computes the cost of memory access instructions. No functionality change intended. llvm-svn: 174422
* [SjLj Prepare] When demoting an invoke instructions to the stack, if the normalChad Rosier2013-02-051-5/+15

* Loop Vectorizer: Handle pointer stores/loads in getWidestType()Arnold Schwaighofer2013-02-051-9/+31
| | | | | | | | | | | | | | | | | In the loop vectorizer cost model, we used to ignore stores/loads of a pointer type when computing the widest type within a loop. This meant that if we had only stores/loads of pointers in a loop we would return a widest type of 8bits (instead of 32 or 64 bit) and therefore a vector factor that was too big. Now, if we see a consecutive store/load of pointers we use the size of a pointer (from data layout). This problem occured in SingleSource/Benchmarks/Shootout-C++/hash.cpp (reduced test case is the first test in vector_ptr_load_store.ll). radar://13139343 llvm-svn: 174377
* Revert accidental commit (ran svn commit from wrong directory).Nick Lewycky2013-02-021-61/+7
| | | | llvm-svn: 174241
* This patch makes "&Cls::purevfn" not an odr use. This isn't what the standardNick Lewycky2013-02-021-7/+61
| | | | | | | | | says, but that's a defect (to be filed). "Cls::purevfn()" is still an odr use. Also fixes a bug in the previous patch that caused us to not mark the function referenced just because we didn't want to mark it odr used. llvm-svn: 174240
* This patch aims to improve compile time performance by increasingPreston Gurd2013-02-011-13/+13
| | | | | | | | | | | | | the SCEV vector size in LoopStrengthReduce. It is observed that the BaseRegs vector size is 4 in most cases, and elements are frequently copied when it is initialized as SmallVector<const SCEV *, 2> BaseRegs. Our benchmark results show that the compilation time performance improved by ~0.5%. Patch by Wan Xiaofei. llvm-svn: 174219
* Revert r174152. The shift amount may overflow and in that case this ↵Nadav Rotem2013-02-011-6/+0

* Linker: correctly link in dbg.declareManman Ren2013-01-311-2/+17
| | | | | | | | | | | | | | | | | | | This is a re-worked version of r174048. Given source IR: call void @llvm.dbg.declare(metadata !{i32* %argc.addr}, metadata !14), !dbg !15 we used to generate call void @llvm.dbg.declare(metadata !27, metadata !28), !dbg !29 !27 = metadata !{null} With this patch, we will correctly generate call void @llvm.dbg.declare(metadata !{i32* %argc.addr}, metadata !27), !dbg !28 Looking up %argc.addr in ValueMap will return null, since %argc.addr is already correctly set up, we can use identity mapping. rdar://problem/13089880 llvm-svn: 174093
* Revert r173946. This breaks compilation of googletest with ClangAlexey Samsonov2013-01-311-11/+2

* Change GetPointerBaseWithConstantOffset's DataLayout argument from aDan Gohman2013-01-312-6/+6
| | | | | | | reference to a pointer, so that it can handle the case where DataLayout is not available and behave conservatively. llvm-svn: 174024

| | | | llvm-svn: 173992
* Convert typeIncompatible to return an AttributeSet.Bill Wendling2013-01-302-6/+20
| | | | | | | There are still places which treat the Attribute object as a collection of attributes. I'm systematically removing them. llvm-svn: 173990
* Linker: correctly link in dbg.declareManman Ren2013-01-301-2/+11

* Fixed a few debug messages and some 80+ violations.Michael Gottesman2013-01-291-9/+10
| | | | llvm-svn: 173832
* Added some periods to some comments and added an overload for operator<< for ↵Michael Gottesman2013-01-291-6/+28
| | | | | | type Sequence so I can print out Sequences in debug statements. llvm-svn: 173831
* Changed DoesObjCBlockEscape => DoesRetainableObjPtrEscape so I can use it to ↵Michael Gottesman2013-01-291-14/+17

* Juggled Debug.h from ObjCARC.h to only the including cpp files thatMichael Gottesman2013-01-294-2/+7
| | | | | | | actually have DEBUG statements. Also changed raw_ostream in said header to be a forward declaration (removing an include). llvm-svn: 173769
* Sorted includes using utils/sort_includes.Michael Gottesman2013-01-298-15/+6
| | | | llvm-svn: 173767
* Added two missing headers from ObjCARCAliasAnalysis.h.Michael Gottesman2013-01-291-0/+3
| | | | | | | | This was missed since whenever I was including ObjCARCAliasAnalysis.h, I was including ObjCARC.h before it which included these includes (resulting in no compilation breakage). llvm-svn: 173764
* Removed InstCombine/Targets as library dependencies for libObjCARCOpts since ↵Michael Gottesman2013-01-291-1/+1
| | | | | | they are unnecessary. llvm-svn: 173763
* Extracted ObjCARCContract from ObjCARCOpts into its own file.Michael Gottesman2013-01-299-1181/+1387
| | | | | | | | This also required adding 2x headers Dependency Analysis.h/Provenance Analysis.h and a .cpp file DependencyAnalysis.cpp to unentangle the dependencies inbetween ObjCARCContract and ObjCARCOpts. llvm-svn: 173760

| | | | llvm-svn: 173759
* Unroll again after running BBVectorizeHal Finkel2013-01-291-0/+4
| | | | | | | | Because BBVectorize may significantly shorten a loop body, unroll again after vectorization. This is especially important when using runtime or partial unrolling. llvm-svn: 173730

* [msan] Mostly disable msan-handle-icmp-exact.Evgeniy Stepanov2013-01-281-6/+24
| | | | | | | | It is way too slow. Change the default option value to 0. Always do exact shadow propagation for unsigned ICmp with constants, it is cheap (under 1% cpu time) and required for correctness. llvm-svn: 173682
