Dan Liew beb21126e2 Move where the Z3 API header files to be scanned by the Python scripts 
is declared out of ``src/api/CMakeLists.txt`` and into
``src/CMakeLists.txt``. We will need this list to generate the
``api_dll.def`` module definition file for MSVC. Whilst I'm here
also fix a stray use of ``USES_TERMINAL`` in ``add_custom_command()``.

Dan Liew ce54f6d957 Fix racing MSVC CMake build. The `libz3` target must have a different 
OUTPUT_NAME than the ``shell`` target to avoid conflicting file names.
 2016-03-04 15:26:09 +00:00
Dan Liew ca6c41e411 Don't append ${OpenMP_CXX_FLAGS} to Z3_DEPENDENT_LIBS. This is wrong 
because this is passed to ``target_link_libraries()``. It just so
happens that ``target_link_libraries()`` will interpret arguments
starting with a dash as a flag to pass to the linker (i.e. in this
case ``-fopenmp``). However in the case of MSVC that flag is ``/openmp``
which is the interpreted as a file path which will lead to a linker
failure later because the linker can't find the file ``\openmp.obj``.

Dan Liew 32e51eda2e Only CMake >= 3.2 supports the `USES_TERMINAL` argument to 
add_custom_command()
 2016-03-04 15:26:09 +00:00
Dan Liew 9f5f8f128f CMake 2.8.12 doesn't support the `continue()` command. 2016-03-04 15:26:09 +00:00
Dan Liew 251527603d Implement a CMake build system. 
This is a large rework of my first attempt at this (#459).

This implementation calls into the recently implemented python scripts
to generate the necessary generated ``.h`` and ``.cpp`` files but is
independent from Python building system otherwise.  Unlike the Python
build system, the generated files are emitted into the build tree to
avoid polluting the source tree. The build system is setup to refuse to
configure if it detects generated files in the source tree. If your
source tree is dirty you can run ``git clean -fx`` to clean your working
directory.

Currently the build succeeds on Linux using CMake 3.4.3 using
the "Unix Makefiles" generator with gcc or clang.

The following notable features are implemented:

* Building of the C and C++ examples and the ``test-z3`` executable.
  These are included from the ``all`` target so you have to tell the
  build system (e.g. make) to build them manually.

* Install (``make install``) and uninstall (``make uninstall``) of libz3
  and its header files. This supports ``DESTDIR`` out of the box because
  CMake supports it.

* An option (``BUILD_LIBZ3_SHARED``) to build libz3 as a static or dynamic library.

* Support for using/not using OpenMP (``USE_OPENMP``)

* Support for using/not using libgmp (``USE_LIB_GMP``)

* Setting the SOVERSION for libz3. I'm not sure if I'm setting the
* number correctly though. This is required by Linux distrubtions that
  wills ship libz3. This needs discussion.

The following notable features are currently not implemented
and are left for future work.

* Support for ARM.
* Support for the foci2 library.
* Support for creating/installing/uninstalling the dotnet, java, python and ml
  bindings.
* Full support for MSVC. Although I've tried to write the CMake code
  with MSVC in mind not all the correct flags are passed to it.
* Support for using the git hash.

This new build system has several advantages other the old build system.

* It is easier for outside contributors to contribute to Z3 when the
  build system is something more standard.
* Incremental builds work properly. With the old build system when
  new code is pulled down the old build directory would need to thrown
  out and a new fresh build had to be performed because the build system
  didn't know how to correctly rebuild the project (e.g. couldn't handle
  new sources being added/removed, compiler flags changing, generated
  files changing, etc...). This is a MASSIVE boost to productivity!
* We now have access rich array of features that CMake provides for
  building C/C++ projects. This means less time spent implementing
  custom build system logic in Python that is already supported by
  CMake.
* CMake supports many IDEs out of the box so it should be fairly
  straight forward to build Z3 with Visual Studio (once support for MSVC
  is added), Xcode, Eclipse CDT, CLion, ..etc.

Andres Notzli 91d6b2cbbb [Z3py] Consistent behavior of eq and ne for FP 
Before, x == y and x != y were returning inconsistent expressions (i.e.
`Not(x == y)` was not the same as `x != y`):

>>> x = FP('x', Float32())
>>> y = FP('y', Float32())
>>> (x == y).sexpr()
'(= x y)'
>>> (x != y).sexpr()
'(not (fp.eq x y))'

`=` does not have the same semantics as `fp.eq` (e.g. `fp.eq` of +0.0
and -0.0 is true while it is false for `=`).
This patch removes the __ne__ method from FPRef, so `x == y` and `x !=
y` use the inherited operations while fpEQ and fpNEQ can be used to
refer to `fp.eq(..)`/`Not(fp.eq(..))`.

This is related to #436.

When doing an AddressSanitized build and running the ``c_example``
it looks like Z3 tries to create too many segments and index out of
bounds. Fixing the checks here causes them to fail which should help
us narrow down the problem.
