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.

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.

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.

builds
of KLEE.
Two configurations (one for each build system) have been added to
TravisCI to do an ASan build.
|
|
The intention of this option was to provide a switch that can be
used to globally enable/disable tests.
This option ended up causing a lot of confusion as can be seen
on the discussion on writing documention for the new build system.
https://github.com/klee/klee.github.io/pull/53
So it was decided to remove this option. This fixes #568 .
|
|
This was a proposal from #500.
@andreamattavelli pointed out that the lit tests are really
system tests rather than integration tests so this commit fixes
the inappropriate naming that I chose.

to the root of the build tree after doing the hack the generate
the lit configuration files.
This will make it easier in the future to run more test configurations
(e.g. by passing options to lit to change KLEE's behaviour).
|
|
fast rather than continuing to run the tests (due to `set -e` at the
beginning of the script).
Although this gives less information in the event of a broken build
it means our builds might finish faster if they are broken and it
also simplifies the script significantly.
|
|
even though configure/build failed. This due to using the `&&` operator
which means failure of commands to execute in this compound statement
will not trigger the script to exit as requested by `set -e`.

This is based off intial work by @jirislaby in #481. However it
has been substantially modified.
Notably it includes a separate build sytem to build the runtimes which
is inspired by the old build system. The reason for doing this is
because CMake is not well suited for building the runtime:
* CMake is configured to use the host compiler, not the bitcode
compiler. These are not the same thing.
* Building the runtime using `add_custom_command()` is flawed
because we can't automatically get transitive depencies (i.e.
header file dependencies) unless the CMake generator is makefiles.
(See `IMPLICIT_DEPENDS` of `add_custom_command()` in CMake).
So for now we have a very simple build system for building the runtimes.
In the future we can replace this with something more sophisticated if
we need it.
Support for all features of the old build system are implemented apart
from recording the git revision and showing it in the output of
`klee --help`.
Another notable change is the CMake build system works much better with
LLVM installs which don't ship with testing tools. The build system
will download the sources for `FileCheck` and `not` tools if the
corresponding binaries aren't available and will build them. However
`lit` (availabe via `pip install lit`) and GTest must already be
installed.
Apart from better support for testing a significant advantage of the
new CMake build system compared to the existing "Autoconf/Makefile"
build system is that it is **not** coupled to LLVM's build system
(unlike the existing build system). This means that LLVM's
autoconf/Makefiles don't need to be installed somewhere on the system.
Currently all tests pass.
Support has been implemented in TravisCI and the Dockerfile for
building with CMake.
The existing "Autoconf/Makefile" build system has been left intact
and so both build systems can coexist for a short while. We should
remove the old build system as soon as possible though because it
creates an unnecessary maintance burden.

GTest has moved from googlecode to GitHub so update URL and directory
name used in source archive as appropriate.

We have to build our own tcmalloc,

fix travis build of upstream STP and also how KLEE links against STP.
|

This could be useful if KLEE tests want to use the bitcode compiler
as a native compiler.

is a build failure. This is so the output shown in the TravisCI
web interface is kept small.

too late so if the unittests failed the lit tests would not run.
|
|
- This works fine for me on OS X now, and has been reported to work on Linux as
well. Enabling across the board although presumably Travis will still only
run single-threaded.
- Fixes #147.
