2019-03-05workaround for LLVM PR39177Julian Büning
provides a workaround for LLVM bug PR39177, which affects LLVM versions 3.9 - 7.0.0: https://bugs.llvm.org/show_bug.cgi?id=39177 This commit is intended to be reverted once support for LLVM versions <= 7 is dropped from KLEE.

2018-11-05Fixed crash on zero size arraysLukas Wölfer
2018-11-05Check for stack overflow in a tested programMartin Nowack
Check if a state reaches the maximum number of stack frames allowed. To be performant, the number of stack frames are checked. In comparison, native execution checks the size of the stack. Still, this is good enough to find possible stack overflows. The limit can be changed with `-max-stack-frames`. The current default is 8192 frames.

--external-calls, updated tests accordingly, and improved documentation on external calls
2018-11-02Introduced a constraint solving option category to which all the options in ↵Cristian Cadar
CmdLineOptions.cpp are currently added.
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)
2018-10-26llvm7: handle new header filesJiri Slaby
createLowerSwitchPass moved in llvm commit 49ca55e3813c to Utils.h. createInstructionCombiningPass moved in llvm commitb5b7fce64c1d to InstCombine.h. So add the includes where needed. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-10-26llvm7: adapt to new openFileForWriteJiri Slaby
In llvm commit 03bcb2143b5c, OpenFlags were split and openFileForWrite accepts one more parameter. Fortunately, openFileForWrite now defaults to F_None, so we remove the parameter completely from llvm 3.7 and later. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-10-26llvm7: WriteBitcodeToFile takes Module &Jiri Slaby
Since llvm commit 06d6207c1c63, WriteBitcodeToFile accepts Module &, not Module *. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-10-26llvm6: handle headers renamingJiri Slaby
Some headers were moved from llvm/Target/ to llvm/CodeGen/. Handle that. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-10-26llvm6: SetVersionPrinter now passes down a streamJiri Slaby
I.e. klee::printVersion should now have a parameter -- the output stream. Change both the prototype and the implementation to handle this properly. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-10-26llvm5: APInt->getSignBit -> getSignMaskJiri Slaby
This was renamed in LLVM commit 54f0462d2b7f, so handle the rename. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
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: Intrinsic::objectsize has three argumentsJiri Slaby
Modify the IntrinsicCleaner accordingly. We do not do anything with the third argument as we do not handle the first argument in any way. 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: handle new file_magic's locationJiri Slaby
llvm 5, moved file_magic to BinaryFormat in commit 19ca2b0f9daed883c21730285d7f04424e5f5f88, so adapt to 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>
2018-10-26llvm5: handle getOrInsertFunction terminatorJiri Slaby
llvm 5 does not terminate getOrInsertFunction parameters with NULL, take care of that. Since commit 9d54400bba7eb04bca80fce97fa170452d19eaf1. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-10-26llvm5: integerPartWidth is from llvm::APFloatBaseJiri Slaby
Otherwise we see: ../lib/Expr/Expr.cpp:331:14: error: no member named 'integerPartWidth' in namespace 'llvm'; did you mean 'llvm::APFloatBase::integerPartWidth'? Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-10-24ShiftChecker: Instrument shift instructions only onceMartin Nowack
As the shift checker could be executed multiple times, we need to avoid that shift instructions are instrumented multiple times as well. Mark the instrumented instruction using metadata and avoid it in successive runs.
2018-10-24ShiftChecker: Avoid unneeded checksMartin Nowack
Do not instrument shift operations with constant shift operations that are smaller than the type size.
