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>

2017-08-07Untabify this file, which was using a mix of spaces and tabs for alignment.Cristian Cadar
2017-08-07Added checks for div/mod by zero and overshifts in constant expressions. ↵Cristian Cadar
Such div/mod by zero expressions would previously crash KLEE. Added two test cases, one for div/mod by zero, the other for overshift. This fixes the bug reported in #268.

2017-07-31Fix build for FreeBSD.Tatiana Tikhomirova
On FreeBSD <sys/capabilities.h> is present in libc, so we don't require libcap there. Close and write functions are located in <unistd.h>.
2017-07-29Added an optional KInstruction* argument to evalConstant and ↵Cristian Cadar
evalConstantExpr which allows us to print the location associated with the constant in any error messages. Added a test case for the unsupported features for taking the address of a label, which exercises the patch.
2017-07-29Added another variant of printFileLine in KInstruction that returns the ↵Cristian Cadar
location as a string. Also added const qualifier to the printFileLine functions

evalConstantExpr also resides), as suggested by an old comment.

2017-07-20Merge pull request #657 from delcypher/vectorized_instructionsCristian Cadar
Implement basic support for vectorized instructions.
2017-07-20Replace assertions of types on LLVM instructions in the Executor with aDan Liew
pass that checks these assertions. This improves several things. * This pass provides more friendly messages than assertions in that it just emits a warning and carries on checking the rest of the instructions. * The takes the checks outside of the Executor's hot path and so avoids checking the same instruction multiple times. Now each instruction is only checked once just before execution starts. The disadvantage of this approach is the check for invariants we expect to hold have been pulled far away from where we expect them to hold. After discussion with @ccadar and @MartinNowack it was decided we will take this hit to readability for better performance and simpler code in the Executor.
2017-07-20Core: TimingSolver, use TimerStatIncrementerJiri Slaby
Do not opencode what we already have in TimerStatIncrementer. This simplifies the code a lot and makes transition to LLVM 4.0 a lot easier. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2017-07-19Implement basic support for vectorized instructions.Dan Liew
We use LLVM's Scalarizer pass to remove most vectorized code so that the Executor only needs to support the InsertElement and ExtractElement instructions. This pass was not available in LLVM 3.4 so to support that LLVM version the pass has been back ported. To check that the Executor is not receiving vector operand types that it can't handle assertions have been added. There are a few limitations to this implementation. * The InsertElement and ExtractElement index cannot be symbolic. * There is no support for LLVM < 3.4.
2017-07-19Fixes bug in TreeStreamWriter::write reported by @gladtbx in #562. Also ↵Cristian Cadar
removes commented out code from that function.
