2017-06-01Refactor file opening code out of `main.cpp` and intoDan Liew
`klee_open_output_file()` function so that it can be used by the Z3Solver.
2017-06-01[Z3] Move the `dump()` methods of the Z3NodeHandle<> specializationsDan Liew
into `Z3Builder.cpp` so they can be called from in gdb.
2017-06-01[Z3] Add assertions in Z3 builder to catch underflow with bad widths.Dan Liew
2017-06-01[Z3] Support another solver failure reason that Z3 might give. I'm goingDan Liew
to guess it means timeout but I'm not 100% sure about this.

2017-05-24Rearchitect ExternalDispatcherDan Liew
Previous changes for LLVM 3.6 using the MCJIT were incredibly hacky. Those changes required creating and destroying the ExternalDispatcher for every call to an external function. This is really bad * It's very poor design. The Executor should not need to know about the internal implementation details of the ExternalDispatcher. * It's likely very inefficient to keep creating and destroying the external dispatcher. The new code does several things. * Moves all of the implementation details into a `ExternalDispatcherImpl` class so that implementation details are not exposed in `ExternalDispatcher.h`. * When using the MCJIT a module is compiled for every (instruction, function) tuple. This is necessary because the MCJIT compiles whole modules at a time and once a module is compiled it cannot be modified and re-compiled. Doing this means we get to reuse already generated code for call sites which hopefully will reduce the overhead of repeatedly executing the same call site. A consequence of this change is that now the dispatcher function name needs to be unique across all modules. To do this we just append the module name because we guarantee that the module name is unique by construction. The code has also been clang-formatted.

It seems there are have been quite a few changes upstream that change the way CMake is invoked. There doesn't seem to be any good reason for doing this.

2017-03-30[TravisCI] Make handling of `TRAVIS_OS_NAME` more robust by not assumingDan Liew
that its value not being `linux` implies `osx`.
2017-03-30[Docker] Unbreak build.Dan Liew
The recent landing of macOS support in TravisCI (3a8bc6a43073b98b58c8cf0c20a930cb2c953b5d) broke the Docker build due to the `TRAVIS_OS_NAME` environment variable not being set by the Docker build. Do the simplest fix for now which is to define the variable. This isn't the cleanest fix but it will do for now.
2017-03-30[CMake] Add the `clean_runtime` top level target to provide an easy wayDan Liew
to clean the runtime build. Unfortuantely there is no way to have the `clean` target trigger the `clean_runtime` target unfortunately.
2017-03-30[CMake] When supported pass `USES_TERMINAL` argument toDan Liew
`ExternalProject_Add_Step()` so that when using Ninja the output of the bitcode build system is shown immediately.
2017-03-30[CMake] Fix #631Dan Liew
This fixes a bug in the bitcode build system where the build would fail if the build directory was a symbolic link (i.e. create a symbolic link for the root of the build tree and try to do the build in that directory). The problem was that `DIR_SUFFIX` implicitly assumed that there was only one way to refer to the build tree which is an incorrect assumption in the presence of symbolic links. This has been fixed by using the `$(realpath)` GNU make built in to resolve all symbolic links. An additional sanity check has been added to check that `SRC_DIR` exists.
2017-03-30[CMake] Try to fix bug reported by #633.Dan Liew
It looks like older LLVM versions that were built from SVN/git didn't have a patch version number (i.e. `3.4svn` rather than `3.4.0svn`).
2017-03-30[TravisCI] Try unbreaking the TravisCI metaSMT build. Copying acrossDan Liew
the `cmake` directory breaks KLEE's CMake build. Just copy across the STP library for now. This really sucks. The script needs to do a better job of installing MetaSMT and its dependencies. For reference here's the error. ``` CMake Error at /usr/lib/cmake/STP/STPTargets.cmake:67 (message): The imported target "stp_simple" references the file "/usr/bin/stp_simple" but this file does not exist. Possible reasons include: * The file was deleted, renamed, or moved to another location. * An install or uninstall procedure did not complete successfully. * The installation package was faulty and contained "/usr/lib/cmake/STP/STPTargets.cmake" but not all the files it references.

2017-03-23[CMake] Unbreak build due to not adding AssignmentValidatingSolver.cppDan Liew
to list of source files. The cause of the breakage was me being to eager and merging #468 before forcing tests to re-run. That PR was written before the CMake build system existed.

assignments against the corresponding `Query` object and check the assignment evaluates correctly. This can be switched on using `-debug-assignment-validating-solver` on the command line.
2017-03-23[TravisCI] Try to unbreak the metaSMT build.Dan Liew
It looks like `deps/stp-git-basic/lib` contains a directory named `cmake` so use `-r` instead in the hack in the `metaSMT.sh`. We didn't catch this before because the script previously just carried on executing if a command failed.
