2012-03-11llvm::SwitchInstStepan Dyatkovskiy
Renamed methods caseBegin, caseEnd and caseDefault with case_begin, case_end, and case_default. Added some notes relative to case iterators. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@152534 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/klee/trunk@152299 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-01Second compatability fix for SwitchInst refactoring (added compatability ↵Stepan Dyatkovskiy
with llvm versions < 3.1). git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@149528 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-01Compatability fix for SwitchInst refactoring.Stepan Dyatkovskiy
The purpose of refactoring is to hide operand roles from SwitchInst user (programmer). If you want to play with operands directly, probably you will need lower level methods than SwitchInst ones (TerminatorInst or may be User). After this patch we can reorganize SwitchInst operands and successors as we want. What was done: 1. Changed semantics of index inside the getCaseValue method: getCaseValue(0) means "get first case", not a condition. Use getCondition() if you want to resolve the condition. I propose don't mix SwitchInst case indexing with low level indexing (TI successors indexing, User's operands indexing), since it may be dangerous. 2. By the same reason findCaseValue(ConstantInt*) returns actual number of case value. 0 means first case, not default. If there is no case with given value, ErrorIndex will returned. 3. Added getCaseSuccessor method. I propose to avoid usage of TerminatorInst::getSuccessor if you want to resolve case successor BB. Use getCaseSuccessor instead, since internal SwitchInst organization of operands/successors is hidden and may be changed in any moment. 4. Added resolveSuccessorIndex and resolveCaseIndex. The main purpose of these methods is to see how case successors are really mapped in TerminatorInst. 4.1 "resolveSuccessorIndex" was created if you need to level down from SwitchInst to TerminatorInst. It returns TerminatorInst's successor index for given case successor. 4.2 "resolveCaseIndex" converts low level successors index to case index that curresponds to the given successor. Note: There are also related compatability fix patches for dragonegg, klee, llvm-gcc-4.0, llvm-gcc-4.2, safecode, clang. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@149484 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-25Patch from Ben Gras which "makes Klee look for the libraries in theCristian Cadar

2012-01-18Nice patch by Gang Hu, Heming Cui and Junfeng Yang fixing a memoryCristian Cadar
leak in KLEE. From Gang Hu: "The memory leak is caused by two reasons. First, the MemoryObject objects are not freed, until the MemoryManager is destroyed. Second, when KLEE allocates a non-fixed MemoryObject object, KLEE also allocates a block of memory which is the same as the object's size. This block of memory is never freed. So, this patch generally does reference counting on the MemoryObject objects, and frees them as soon as the reference count drops to zero." Many thanks to Paul Marinescu as well, who tested this patch thoroughly on the Coreutils benchmarks. On 1h runs, the memory consumption typically goes down by 1-5%, but some applications which see more significant gains. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@148402 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-11This is a workaround for the infinite loop reported at Cristian Cadar
http://keeda.stanford.edu/pipermail/klee-dev/2011-August/000723.html KLEE needs to use --fno-builtin when compiling its version of memset. However, this patch also adds the workaround suggested by Paul in the thread above, since support for --fno-builtin was added to llvm-gcc only after LLVM 2.9 was released. More details about this issue can be found here: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20110411/119376.html http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20110711/124131.html Thanks to Paul and arrowdodger for their explanations and patches. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@146350 91177308-0d34-0410-b5e6-96231b3b80d8
