2018-10-30Base time API upon std::chronoFrank Busse
This should not change the behaviour of KLEE and mimics the old API. - functions moved from util into time namespace - uses time points and time spans instead of double - CLI arguments now have the form "3h5min8us" Changed command line parameters: - batch-time (double to string) - istats-write-interval (double to string) - max-instruction-time (double to string) - max-solver-time (double to string) - max-time (double to string) - min-query-time-to-log (double to string) - seed-time (double to string) - stats-write-interval (double to string) - uncovered-update-interval (double to string) - added: log-timed-out-queries (replaces negative max-solver-time)
2018-10-26llvm5: CallSite.paramHasAttr is indexed from 0Jiri Slaby
Since LLVM 5 commit 1f8f0490690b, CallSite.paramHasAttr is indexed from 0, so make sure we use correct indexing in klee. And use CallSite.hasRetAttr for return attributes. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-10-26llvm5: use MutableArrayRef for APFloat::convertToIntegerJiri Slaby
In llvm 5, since commit 957caa243d9270df37a566aedae3f1244e7b62ef, the first parameter to APFloat::convertToInteger is MutableArrayRef. So handle that. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-10-26llvm5: SwitchInst case functions now return pointersJiri Slaby
Starting llvm 5, SwitchInst->findCaseValue() now has to be dereferenced using ->. So do so, otherwise we see: ../lib/Core/Executor.cpp:1598:38: error: no member named 'getCaseSuccessor' in 'llvm::SwitchInst::CaseIteratorImpl<llvm::SwitchInst::CaseHandle>'; did you mean to use '->' instead of '.'? BasicBlock *caseSuccessor = i.getCaseSuccessor(); ^ Signed-off-by: Jiri Slaby <jirislaby@gmail.com>

2018-10-23Move optimization specific headers away from the project include directoryMartin Nowack
Don't pollute the project include directory with optimization specific headers.
2018-10-23Remove condition check before function invocationMartin Nowack
Conditions are checked inside of `optimizeExpr()` anyway. This simplifies the code a lot.
2018-10-23Move ConstantExpr check inside optimizeExpr functionMartin Nowack
2018-10-23optimizeExpr: return the result as return value instead as function argumentMartin Nowack
simplifies code a lot.
2018-10-23Make valueOnly parameter of optimizeExpr explicitMartin Nowack
avoid ambiguity of valueOnly parameter
2018-10-23Added support for KLEE value-based array optimizationAndrea Mattavelli
2018-10-23Added support for KLEE index-based array optimizationAndrea Mattavelli
2018-10-16Renamed klee/CommandLine.h to klee/SolverCmdLine.h, since this file is meant ↵Cristian Cadar
to have only solver options.
2018-10-10fix handling of failing external callsFrank Busse
Currently KLEE only handles the first segfault in external calls as it doesn't unblock SIGSEGV afterwards. This patch unblocks the signal and enables handling of multiple failing calls.
2018-10-03Marking resolve methods as constCristian Cadar
2018-10-03Refactored AddressSpace::resolve() by creating a new function ↵Cristian Cadar
AddressSpace::checkPointerInObject() that is called in both the forward and the backward searches. This makes the code more modular and removes a large part of duplicated code and should also address the non-deterministic coverage in the resolve() function which affects Codecov reports.

2018-09-18llvm4: gep_type_iterator has no operator*Jiri Slaby
Starting with LLVM 4, we have getStructTypeOrNull(), so use it. operator* in post-4 will have a different semantics. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-09-18llvm4: PointerType is not SequentialTypeJiri Slaby
So handle the type specially whenever needed. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-09-18llvm4: use chrono helpers from LLVMJiri Slaby
LLVM 4 removes the old time interface and starts using the C++11's chrono. So switch to that in klee for LLVM 4 too. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>

2018-08-03Replace remaining *Inst::Create() calls with llvm::BuilderMartin Nowack
Replace the remaining occurrences of `Inst::Create()` with `llvm::Builder` to manage metadata automatically and to fold instructions. C++11 it and clang-format
2018-07-23ExternalDispatcher: setErrorStr for EngineBuilderJulian Büning
addresses comment made by @adrianherrera in #385
2018-07-12llvm38: no more implicit iteratorsRichard Trembecký
LLVM commit eac309550f25 removed implicit iterator conversions. So we have to get the iterators explicitly now. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-07-12llvm38: no rounding in APFloatJiri Slaby
The rounding was removed because it was never needed: llvm-mirror/llvm@ff278be Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-07-11Added "override" in Executor.h to silence compiler warnings (and ran ↵Cristian Cadar
clang-format on patch)
2018-07-11Removed support for klee_make_symbolic with 2 arguments. This has been ↵Cristian Cadar
deprecated for many years now and causes problems during replay. Changed and simplified affected test case.
2018-07-04Fix compiler warnings if assertions are disabledMartin Nowack
2018-07-04Reorder linking and optimizationsMartin Nowack
Link intrinsic library before executing optimizations. This makes sure that any optimization run by KLEE on the module is executed for the intrinsic library as well. Support .ll files as input for KLEE as well.

2018-05-24llvm37: handle GetElementPtrInst::Create's new parameterJiri Slaby
LLVM 3.7 added a PointeeType parameter to GetElementPtrInst::Create. Let's handle that by a macro called KLEE_LLVM_GEP_TYPE, defined in Version.h. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-05-22Removed .c_str() from getSourceLocation callsCristian Cadar
2018-05-22Renamed printFileLine to getSourceLocation (as suggested by @delcypher) to ↵Cristian Cadar

2018-05-22Simplified printFileLine by using std::to_string, and removed unneeded ↵Cristian Cadar
version that takes an argument a stream
2018-05-21stop using DEBUG macro nameJiri Slaby
This is too generic and llvm 6.0 defines DEBUG as follows: #define DEBUG(X) DEBUG_WITH_TYPE(DEBUG_TYPE, X) This then results in various build failures where once the macro is defined, once it is not. So rename this generic macro to KLEE_ARRAY_DEBUG. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>

2018-05-05Fix handling of errno if external functions are invokedMartin Nowack
If an external function in KLEE is invoked, it might update errno. Previously, the errno specific variable in a state was only updated if it was part of the executed instructions. That opened up a timeframe that increased the likelihood of errno being overwritten by another method call. This patch fixes two issues: * the errno of the KLEE process state is updated before the external function call allowing to detect changes to it later on * after the external call, the memory object of errno is directly updated with its new value, reducing the likelihood to be overwritten by another call Additional features: * Add support for `errno()` for Darwin as well. * Simplified errno handling in POSIX layer
