2019-03-19Fix representation of ReadExpr of equivalent arraysMartin Nowack
ObjectStates can be shared between multiple states. A read expression of a symbolic object can be represented differently depending on previous read expression on the same object. If the read expression uses a symbolic index, all pending updates will become entries in the update list of the object state. If the same object state is read again, with a concrete index, the latest update list item will be referenced, even though it might contain more recent but non-essential updates. If, instead, a concrete read will be executed first, it does not contain the non-essential updates. For both executions, the ReadExpr with a constant index will have two different representations, which is not intented. This patch makes sure, we do not include more recent, non-essential updates for concrete reads. Fixes #921

2019-03-18Disable optimisation for functions that contain KLEE callsMartin Nowack
Compilers are allowed to hoist function calls and do GVE. This is currently done even without `--optimization` enabled. This is unfortunate in the context of KLEE function calls that might depend on specific code position without direct control flow dependencies. In such cases, function calls can be hoisted. To circumvent this, disallow to optimise functions that contain such calls by default. This might reduce optimisation for some functions containing such function calls but still allows it for all others. This patch adds an additional pass, that detects all functions starting with a prefix `klee_` and disable optimisations for functions containing such calls. This is enabled by default but can be disabled by `--klee-call-optimisation=false`.

2019-03-17Fix `true` invocation in case docker image could not be pushedMartin Nowack
2019-03-17Use newer uclibc version: libc++ requires locale support activatedMartin Nowack
2019-03-17Add travis support to build with libc++Martin Nowack
Enable libc++ support by default but disable for LLVM < 3.7 as not supported. Disable support for Mac OSX: wllvm is not working well with dylib but Mac OSX currently requires dynamic version compiled. In general it should be possible, maybe later version.
2019-03-17Add libc++ as build dependency to KLEEMartin Nowack
2019-03-17Cmake enhance detection of C++ libraries and include filesMartin Nowack
* Use directory instead of libc++ files * support `bca` and `ba` files * Add additional checks if directories exist
2019-03-17Fix libc++ testcasesMartin Nowack
* remove wrapper script invocation and script * add build instruction to test cases * added additional checks * add check to avoid execution of tests if KLEE is not compiled with libc++
