2012-06-01PR1255: case ranges.Stepan Dyatkovskiy
IntItem cleanup. IntItemBase, IntItemConstantIntImp and IntItem merged into IntItem. All arithmetic operators was propogated from APInt. Also added comparison operators <,>,<=,>=. Currently you will find set of macros that propogates operators from APInt to IntItem in the beginning of IntegerSubset. Note that THESE MACROS WILL REMOVED after all passes will case-ranges compatible. Also note that these macros much smaller pain that something like this: if (V->getValue().ugt(AnotherV->getValue()) { ... } These changes made IntItem full featured integer object. It allows to make IntegerSubset class generic (move out all ConstantInt references inside and add unit-tests) in next commits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157810 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-28PR1255: Case RangesStepan Dyatkovskiy
Implemented IntItem - the wrapper around APInt. Why not to use APInt item directly right now? 1. It will very difficult to implement case ranges as series of small patches. We got several large and heavy patches. Each patch will about 90-120 kb. If you replace ConstantInt with APInt in SwitchInst you will need to changes at the same time all Readers,Writers and absolutely all passes that uses SwitchInst. 2. We can implement APInt pool inside and save memory space. E.g. we use several switches that works with 256 bit items (switch on signatures, or strings). We can avoid value duplicates in this case. 3. IntItem can be easyly easily replaced with APInt. 4. Currenly we can interpret IntItem both as ConstantInt and as APInt. It allows to provide SwitchInst methods that works with ConstantInt for non-updated passes. Why I need it right now? Currently I need to update SimplifyCFG pass (EqualityComparisons). I need to work with APInts directly a lot, so peaces of code ConstantInt *V = ...; if (V->getValue().ugt(AnotherV->getValue()) { ... } will look awful. Much more better this way: IntItem V = ConstantIntVal->getValue(); if (AnotherV < V) { } Of course any reviews are welcome. P.S.: I'm also going to rename ConstantRangesSet to IntegersSubset, and CRSBuilder to IntegersSubsetMapping (allows to map individual subsets of integers to the BasicBlocks). Since in future these classes will founded on APInt, it will possible to use them in more generic ways. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157576 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-30Re-factored RuntimeDyLd:Danil Malyshev
1. The main works will made in the RuntimeDyLdImpl with uses the ObjectFile class. RuntimeDyLdMachO and RuntimeDyLdELF now only parses relocations and resolve it. This is allows to make improvements of the RuntimeDyLd more easily. In addition the support for COFF can be easily added. 2. Added ARM relocations to RuntimeDyLdELF. 3. Added support for stub functions for the ARM, allowing to do a long branch. 4. Added support for external functions that are not loaded from the object files, but can be loaded from external libraries. Now MCJIT can correctly execute the code containing the printf, putc, and etc. 5. The sections emitted instead functions, thanks Jim Grosbach. MemoryManager.startFunctionBody() and MemoryManager.endFunctionBody() have been removed. 6. MCJITMemoryManager.allocateDataSection() and MCJITMemoryManager. allocateCodeSection() used JMM->allocateSpace() instead of JMM->allocateCodeSection() and JMM->allocateDataSection(), because I got an error: "Cannot allocate an allocated block!" with object file contains more than one code or data sections. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153754 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-20RuntimeDyldMachO has the ability to keep track ofSean Callanan
relocations (i.e., pieces of data whose addresses are referred to elsewhere in the binary image) and update the references when the section containing the relocations moves. The way this works is that there is a map from section IDs to lists of relocations. Because the relocations are associated with the section containing the data being referred to, they are updated only when the target moves. However, many data references are relative and also depend on the location of the referrer. To solve this problem, I introduced a new data structure, Referrer, which simply contains the section being referred to and the index of the relocation in that section. These referrers are associated with the source containing the reference that needs to be updated, so now regardless of which end of the relocation moves, the relocation will now be updated correctly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153147 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-08Taken into account Duncan's comments for r149481 dated by 2nd Feb 2012:Stepan Dyatkovskiy
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20120130/136146.html Implemented CaseIterator and it solves almost all described issues: we don't need to mix operand/case/successor indexing anymore. Base iterator class is implemented as a template since it may be initialized either from "const SwitchInst*" or from "SwitchInst*". ConstCaseIt is just a read-only iterator. CaseIt is read-write iterator; it allows to change case successor and case value. Usage of iterator allows totally remove resolveXXXX methods. All indexing convertions done automatically inside the iterator's getters. Main way of iterator usage looks like this: SwitchInst *SI = ... // intialize it somehow for (SwitchInst::CaseIt i = SI->caseBegin(), e = SI->caseEnd(); i != e; ++i) { BasicBlock *BB = i.getCaseSuccessor(); ConstantInt *V = i.getCaseValue(); // Do something. } If you want to convert case number to TerminatorInst successor index, just use getSuccessorIndex iterator's method. If you want initialize iterator from TerminatorInst successor index, use CaseIt::fromSuccessorIndex(...) method. There are also related changes in llvm-clients: klee and clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152297 91177308-0d34-0410-b5e6-96231b3b80d8
