2018-07-04runtime: remove obsolete code for building modules instead of archivesJulian Büning
2018-07-04Reorder linking and optimizationsMartin Nowack
Link intrinsic library before executing optimizations. This makes sure that any optimization run by KLEE on the module is executed for the intrinsic library as well. Support .ll files as input for KLEE as well.
2018-07-04Reorganise runtime libraries provided by KLEEMartin Nowack
Strictly differentiate between the following type of libraries: * FreeStanding: contains minimal amount of methods a compiler would expect * klee-libc: contains a minimal libc implementation * POSIX: contains a POSIX layer that can be used on top of a libc implementation * Intrinsic: contains additional runtime functions which provide KLEE-specific functionalities, (e.g. checks) Builds always archives instead of single modules. This allows to reduce linked-in dependencies of tested applications.

2018-06-11cmake: find_llvm, handle libLLVM-version.so properlyJiri Slaby
Some builds of llvm contain a lib like this: /usr/lib64/libLLVM-3.9.so Extend the regular expression, so that we really return what we are supposed to. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>

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>
2018-05-24test: add versions of some tests for LLVM 3.7Richard Trembecký
Clone some tests to have their 3.7 version. 'call's, 'load's and 'getelementptr's match the new specification in them. @andreamattavelli: Fixed test cases: BitCastAlias test cases included modification to alias specifications that require LLVM 3.8 [v2] added comments what was changed and why [v3] the new tests are without suffix, the old ones have ".leq36".

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>
2018-05-23test: add parenthesis around & operandsJiri Slaby
Some compilers are picky, so avoid the warning by additional parentheses: test/VectorInstructions/integer_ops_unsigned_symbolic.c:85:22: warning: & has lower precedence than <; < will be evaluated first [-Wparentheses] 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
