2018-05-24llvm37: handle getRegisteredOptionsJiri Slaby
In LLVM 3.7 and later, getRegisteredOptions takes no arguments and returns the map directly. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>

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>

2018-05-22some housekeeping in Passes.h and IntrinsicCleaner.cppJulian Büning
This commit addresses the following: * remove unused variables block_split (::runOnBasicBlock) and LI (::IntrinsicCleanerPass) in IntrinsicCleanerPass * add `dirty = true` to `Intrinsic::vacopy` case * use `eraseFromParent()` methods instead of `removeFromParent()` and `delete` * add `override` keyword to `runOn{Module,Function}` methods

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

2018-05-01fix compilation warningFrank Busse
2018-04-09doDumpStates: incorrectly increments statsFrank Busse
doDumpStates calls stepInstruction and therefore indirectly increases time and instruction statistics for all dangling (dumped) states. This patch removes the call, but now the timing stats for the last executed state are lost, as StatsTracker::stepInstruction isn't called anymore.

2018-02-01llvm50: use auto variable instead of SwitchInst::CaseItJiri Slaby
llvm50 changed the semantics of SwitchInst::CaseIt and started using "auto" variable type. So use it here too for all versions greater than 3.4 -- 3.4 does not support this semantics yet. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
