2016-08-04klee: add exit-on-error-type parameterJiri Slaby
It allows stopping the execution on some conditions like assertions. The use is like: klee -exit-on-error-type=Assert -exit-on-error-type=External file.llvm This is especially useful in the SV-COMP. A test to cover the new parameter was added too. Signed-off-by: Jiri Slaby <jslaby@suse.cz>
2015-12-17Refactoring: Moving klee_warning/_error functions to ErrorHandling in ↵Martin Nowack
Support directory
2015-12-11Reword help description for ``--silent-klee-assume`` command lineDan Liew
flag as suggested by @ccadar
2015-12-11Add command line flag ``--silent-klee-assume``to suppress errors due toValentin Wüstholz
infeasible assumptions.
2015-06-03Added an option --readable-posix-inputs which is used to turn on/off the CEX ↵Cristian Cadar
preferences added in the POSIX model. Removed option --prefer-cex which controlled all CEX preferences.
2015-02-13refactor integer overflow detection, add signed intLuca Dariz
Instead of checking for every possible casse which result in overflow, it is much simpler to perform the operation using integers with bigger dimension and check if the result overflow
2015-02-13Detect overflow of unsigned add, sub and mul operationsLuca Dariz
This requires clang with -fsanitize=unsigned-integer-overflow tested with clang and llvm 3.4.2
2015-02-13Revert "Merged @luckyluke's change for detecting overflow of unsigned add, sub"Cristian Cadar
Will redo the merge to preserve original commits. This reverts commit a743d7072d9ccf11f96e3df45f25ad07da6ad9d6.
2015-02-10Merged @luckyluke's change for detecting overflow of unsigned add, subCristian Cadar
and mul operations. Refactored tests into two main cases, and disabled them on LLVM 2.9, which does not support -fsanitized=*signed-integer-overflow.
2014-09-19Removed code related to underConstrained, as it is unused (issue pointed out ↵Cristian Cadar
by @hpalikareva).
2014-09-13Add KLEE specific DEBUG macros.Daniel Dunbar
- This allows us to build in +Asserts mode even when LLVM isn't (by disabling the checks in that mode). - Eventually it would be nice to just move off of LLVM's DEBUG infrastructure entirely and just have our own copy, but this works for now. - Fixes #150.
2014-05-29Remove #include <iostream> to avoid static constructorsMartin Nowack
iostream injects static constructor function into every compilation unit. Remove this to avoid it.
2014-05-29Refactoring from std::ostream to llvm::raw_ostreamMartin Nowack
According to LLVM: lightweight and simpler implementation of streams.
2014-02-06Implement const_iterator interface for SpecialFunctionHandler soDan Liew
that clients can access HandlerInfo nicely.
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

2010-06-28Applied Stefan Bucur's patch fromCristian Cadar
http://llvm.org/bugs/show_bug.cgi?id=6690. The patch adds specialized versions of klee_get_value for different types, fixing the previous klee_get_value function that sometimes truncated 64bit parameters to 32bit. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@107006 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-03Fix computation of GetElementPtr offset for 64-bit targets.Daniel Dunbar
- Precomputed constants were being truncated to 32-bits! - This was actually the problem with new[]/delete[], I failed to look at the generated code for new[] to realize that the compiler is generating the offset pointer, not the runtime library. - All tests now pass on x86-64! git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@77930 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-28KLEE64: Fix a type conversion problem with calls to klee_make_symbolic; thereDaniel Dunbar
are probably lots more of this -- we really need coercion and argument validation to be checked outside of the individual intrinsic handlers. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@77311 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-14More ConstantExpr cleanup.Daniel Dunbar

2009-06-14Remove some unused functionality.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73329 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-14Change AddressSpace::resolveOne to take a ConstantExpr directly (and to allowDaniel Dunbar
64-bit addresses). git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73327 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-14Add ConstantExpr::{getLimitedValue,getZExtValue}.Daniel Dunbar
- For use in situations where the range of the constant is known to fit in a uint64 (or smaller), or the extra bits don't matter. - No (intended) functionality change. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73326 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Sink getConstantValue into ConstantExpr.Daniel Dunbar

2009-06-04Change Solver::getValue to make explicit that result is a ConstantExpr.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72860 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Finish removing uses of Expr::isConstant.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72859 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Start removing uses of Expr::isConstant.Daniel Dunbar
- These should use cast<>, isa<>, or dyn_cast<> as appropriate (or better yet, changed to use ref<ConstantExpr> when the type is known). git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72857 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Move isConstant from ref<> to Expr::Daniel Dunbar
- Ref.h is now freestanding. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72824 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-03Kill off specialized ref<> forwarding methods, in the interest of making it aDaniel Dunbar
more standard reference counting wrapper. - The only interesting changes here are in Ref.h, everything else is just updating foo.method to use foo->method instead. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72777 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-02Use ConstantExpr::alloc instead of ref<Expr> directlyDaniel Dunbar
- The "constant optimization" embedded inside ref<Expr> is going away. - No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72730 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-01Kill off klee_malloc_n, we don't want to support this.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72693 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-22Add "name" argument to klee_make_symbolic, and kill off klee_make_symbolic_name.Daniel Dunbar
- For compatibility we still accept 2 argument form of klee_make_symbolic, but this will go away eventually. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72265 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-21Initial KLEE checkin.Daniel Dunbar
- Lots more tweaks, documentation, and web page content is needed, but this should compile & work on OS X & Linux. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72205 91177308-0d34-0410-b5e6-96231b3b80d8
