2014-05-29Refactoring from std::ostream to llvm::raw_ostreamMartin Nowack
According to LLVM: lightweight and simpler implementation of streams.
2014-04-24Renamed GetTotalMemoryUsage to GetTotalMallocUsageMartin Nowack
2014-04-24Fix handling of memory usage in KLEE.Martin Nowack
Memory usage API in LLVM since 3.3 is not working the way it is intended by KLEE. This ports the pre 3.3. version to KLEE. Fixes the malloc test case.
2014-02-24Improved help message for make-concrete-symbolic and fixed some typos.Cristian Cadar
2013-12-19Added a few comments to Executor::getLastNonKleeInternalInstruction()Dan Liew
emphasising that the function cannot be returned from early.

file as well.
2013-12-19If error location information is missing be explicit about it. ThisDan Liew
is more helpful because often the next message is "Now ignoring error at this location". Which is slightly confusing when no location is shown.
2013-12-19Allow to specify KLEE-internal functionsMartin Nowack
KLEE provides runtime library functions to do detection of bugs (e.g. overflow). This runtime functions are not the location of the bugs but it is the next non-runtime library function from the stack. Use the caller inside that function to indicate where the bug is.
2013-12-06Deprecate LLVM 2.8 and lowerMartin Nowack
2013-12-05Fix timer leakMartin Nowack
2013-11-13Fix using assembler addresses for global variablesMartin Nowack
Format of assembler address strings are different with newer LLVM version (They don't have a prefix anymore). This fix takes care of newer LLVM versions (>=3.3) as well.

2013-08-27Port to LLVM 3.3Martin Nowack
Major changes are: - Switching to llvm-link to build archive files - Use GetMallocUsage instead of GetTotalMemoryUsage (be aware of bug in LLVM 3.3 http://llvm.org/bugs/show_bug.cgi?id=16847) - intrinsic library functions like memcpy/mov/set use weak linkage to be replaced by e.g. uclibc functions - rewrote linking with library - enhanced MemoryLimit test case to check if mallocs were successful
2013-08-14Slight refactor of code initialising memory for argments/environment c-stringsDan Liew
so that it is easier to read.
2013-08-06TimingSolver and constructSolverChain() no longer coupled with pointers to ↵Hristina Palikareva
STPSolver objects. Timeout is now set by the solver at the top of the solver chain rather than by STPSolver.
2013-08-06Renaming solver-related command-line options in order to decouple them from ↵Hristina Palikareva
STP. More specifically, command-line options max-stp-time, use-forked-stp and stp-optimize-divides renamed to max-solver-time, use-forked-solver and solver-optimize-divides, respectively. Option of running the SMT solver in a separate process (i.e. forked) set to true by default. Options of running SMT solver forked and with optimized divides made available to Kleaver as well.

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
