* Implement .rel relocation for R_ARM_ABS32 in MCJIT.Tim Northover2012-10-032-2/+26
| | | | | | Patch by Amara Emerson. llvm-svn: 165128
* This Patch corrects a problem whereby the optimization to use a faster dividePreston Gurd2012-10-031-5/+15
| | | | | | | | | | | | | | instruction (for Intel Atom) was not being done by Clang, because the type context used by Clang is not the default context. It fixes the problem by getting the global context types for each div/rem instruction in order to compare them against the types in the BypassTypeMap. Tests for this will be done as a separate patch to Clang. Patch by Tyler Nowicki. llvm-svn: 165126
* A DAGCombine optimization for mergeing consecutive stores to memory. The ↵Nadav Rotem2012-10-032-0/+668
| | | | | | | | | | | | | | | | | | | | | optimization is not profitable in many cases because modern processors perform multiple stores in parallel and merging stores prior to merging requires extra work. We handle two main cases: 1. Store of multiple consecutive constants: q->a = 3; q->4 = 5; In this case we store a single legal wide integer. 2. Store of multiple consecutive loads: int a = p->a; int b = p->b; q->a = a; q->b = b; In this case we load/store either ilegal vector registers or legal wide integer registers. llvm-svn: 165125

* When mangling an APSInt with the ms abi, make sure to look at all nibbles.Nico Weber2012-10-032-1/+10

* As opposed to the clang-fixit tool described onDaniel Jasper2012-10-033-5/+74
| | | | | | | | | http://clang.llvm.org/docs/ClangTools.html, this adds -fixit option to clang-check. Thus, clang-check can become a general-purpose tool to run clang capitalizing on the info stored in a compilation database. Review: http://llvm-reviews.chandlerc.com/D51 llvm-svn: 165110

* Try to use a better set of abstractions for computing the alignmentChandler Carruth2012-10-032-20/+87
| | | | | | | | | | | | | | | | | | | | necessary during rewriting. As part of this, fix a real think-o here where we might have left off an alignment specification when the address is in fact underaligned. I haven't come up with any way to trigger this, as there is always some other factor that reduces the alignment, but it certainly might have been an observable bug in some way I can't think of. This also slightly changes the strategy for placing explicit alignments on loads and stores to only do so when the alignment does not match that required by the ABI. This causes a few redundant alignments to go away from test cases. I've also added a couple of tests that really push on the alignment that we end up with on loads and stores. More to come here as I try to fix an underlying bug I have conjectured and produced test cases for, although it's not clear if this bug is the one currently hitting dragonegg's gcc47 bootstrap. llvm-svn: 165100

| | | | | | | | | | | | | * nullptr used to be mapped to ERROR, now mapped to nullptr * integral was missing * expressions now have their own error message, so they won't reach this. Map them to ERROR. Note that clang usually crashes before emitting this diagnostic anyway (see PR13984), so this change alone doesn't have an observable effect. It makes the code more correct though. llvm-svn: 165095

These two Process plugins will hardcode their DynamicLoader name to be the DynamicLoaderDarwinKernel so the correct DynamicLoader is picked, and return the kernel load address as the ImageInfosAddress. <rdar://problem/12417038> llvm-svn: 165080
* [analyzer] Adjust the return type of an inlined devirtualized method call.Jordan Rose2012-10-033-6/+109
| | | | | | | | | | | | | | | | | | | | | | | | | In C++, overriding virtual methods are allowed to specify a covariant return type -- that is, if the return type of the base method is an object pointer type (or reference type), the overriding method's return type can be a pointer to a subclass of the original type. The analyzer was failing to take this into account when devirtualizing a method call, and anything that relied on the return value having the proper type later would crash. In Objective-C, overriding methods are allowed to specify ANY return type, meaning we can NEVER be sure that devirtualizing will give us a "safe" return value. Of course, a program that does this will most likely crash at runtime, but the analyzer at least shouldn't crash. The solution is to check and see if the function/method being inlined is the function that static binding would have picked. If not, check that the return value has the same type. If the types don't match, see if we can fix it with a derived-to-base cast (the C++ case). If we can't, return UnknownVal to avoid crashing later. <rdar://problem/12409977> llvm-svn: 165079
* [analyzer] Push evalDynamicCast and evalDerivedToBase up to Store.Jordan Rose2012-10-033-103/+95
| | | | | | | | | These functions are store-agnostic, and would benefit from information in DynamicTypeInfo but gain nothing from the store type. No intended functionality change. llvm-svn: 165078
* Teach getCXXRecordDeclForPointerType about references.Jordan Rose2012-10-034-32/+30
| | | | | | | | | Then, rename it getPointeeCXXRecordDecl and give it a nice doc comment, and actually use it. No intended functionality change. llvm-svn: 165077

* The early if conversion pass is ready to be used as an opt-in.Jakob Stoklund Olesen2012-10-033-5/+11
| | | | | | | | | | | Enable the pass by default for targets that request it, and change the -enable-early-ifcvt to the opposite -disable-early-ifcvt. There are still some x86 regressions when enabling early if-conversion because of the missing machine models. Disable the pass for x86 until machine models are added. llvm-svn: 165075

* Switch the SetVector::remove_if implementation to use partition whichChandler Carruth2012-10-032-3/+6
| | | | | | | | | | | | | | preserves the values of the relocated entries, unlikely remove_if. This allows walking them and erasing them. Also flesh out the predicate we are using for this to support the various constraints actually imposed on a UnaryPredicate -- without this we can't compose it with std::not1. Thanks to Sean Silva for the review here and noticing the issue with std::remove_if. llvm-svn: 165073
* Fix a serious X86 instruction selection bug. InEvan Cheng2012-10-022-3/+30
| | | | | | | | | | | | | X86DAGToDAGISel::PreprocessISelDAG(), isel is moving load inside callseq_start / callseq_end so it can be folded into a call. This can create a cycle in the DAG when the call is glued to a copytoreg. We have been lucky this hasn't caused too many issues because the pre-ra scheduler has special handling of call sequences. However, it has caused a crash in a specific tailcall case. rdar://12393897 llvm-svn: 165072
