2018-07-23fix: LLVM 3.5, begin_user() instead of begin_use()Julian Büning
With version 3.5, LLVM introduced a subtle semantic change in the API of `Value`. With that change, `use_begin()` is renamed to `user_begin()`. Additionally, a new method `use_begin()` with a different meaning was introduced. Now, `use_begin()` actually iterates over `Use`s, whereas before, dereferencing it would give a `User *`. For further details, please refer to https://reviews.llvm.org/rL203364. Due to the reintroduction of `use_begin()`, existing code may still compile, although the semantics have changed. In the code changed with this patch, all `dyn_cast`s for `Use` fail and the else branch is always taken.

2018-07-12llvm38: no more implicit iteratorsRichard Trembecký
LLVM commit eac309550f25 removed implicit iterator conversions. So we have to get the iterators explicitly now. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>

2018-07-04Extensive updates to the build script for dependencies and dockerMartin Nowack
Building/managing dependencies of KLEE are not easy. This script should change this. Features: * script install different versions in their specific directories This allows: - to have different versions in parallel installed: llvm, solvers - to have different optimization levels installed (Debug, no-debug, assertions, optimized) - to have different versions of instrumentation enabled (address, memory, leakage, undefined behavior) * the script is kept distribution agnostic: assuming basic packages are installed (a compiler), use `scripts/build/ubuntu-dependencies.sh` to install ubuntu specific ones * the script does not install any file into system directories (sudo is not required) files are only installed into a user specified BASE directory The same scripts are used for either local setup (`scripts/build/local_install.sh`) or create a docker image based of your current source folder (`scripts/build/build_docker.sh`) Change the defaults permanently by modifying (`scripts/build/common-defaults.sh`) or change them on the fly by providing them as environment variables on the command line. The same scripts are also used for TravisCI, so we test what we are using.
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.
