      CIVL: The Concurrency Intermediate Verification Language
                               v 0.12

------------------------------ Overview -------------------------------

CIVL is a framework encompassing...

 * a programming language, CIVL-C, which adds to C a number of
   concurrency primitives, as well as the ability to define
   functions in any scope.  Together, these features make for
   a very expressive concurrent language that can faithfully
   represent programs using various APIs and parallel languages,
   such as MPI, OpenMP, CUDA, and Chapel. CIVL-C also provides
   a number of primitives supporting verification.
 * a model checker which uses symbolic execution to verify a
   number of safety properties of CIVL-C programs.   The model
   checker can also be used to verify that two CIVL-C programs
   are functionally equivalent.
 * a number of translators from various commonly-used languages
   and APIs to CIVL-C. (This part is still a work in progress.)

CIVL is developed by the Verified Software Laboratory at the
University of Delaware Department of Computer Science.

-------------------------- Updates from v 0.11 -------------------------

1. Bugs fixed:
   better handling for the return value of the main function;
   error handling for $malloc statements that are casted to void*;
   correct translation of pointer subtraction;
   better handling for implicit array-to-pointer conversion;
   various bugs of the side-effect remover;
   supporting boolean/int conversion and comparison;
   supporting the implicit initialization of static variables;
   improvement of the clarity of error messages for various circumstances;
   improvement of the format analysis of printf/fprintf;
   improvement of the $bundle_pack function to allow non-concrete indexes;
   etc.

2. New types and language constructs: $range, $domain, $for, $parfor, etc.
   Refer to CIVL manual for details: Section 6.1.4 for $range and $domain,
   Section 6.3.3 for $for, and Section 7.3 for $parfor.
   
3. Enhancement:

4. New system functions:
   _Bool $equals(void *x, void *y);
   _Bool $contains(void *ptr1, void *ptr2);
   void $array_init(void *array, int length, void *elementValue);
   Refer to Section 6.4.2 of CIVL manual for details.
  
5. New features:
   GUI mode for replay a trace. Just type "civl replay *.cvl -gui" and hit enter.

------------------------- Binary Installation -------------------------

For most users, this will be the easiest way to install and use CIVL.

1. Install a Java 7 SDK if you have not already.  Go to
http://www.oracle.com/technetwork/java/javase/downloads/ for the
latest from Oracle.  On linux, you can optionally sudo apt-get install
openjdk-7-jdk.

2. If you already have the VSL dependencies library, you may
skip this step.  Otherwise, download the archive of VSL
dependencies from http://vsl.cis.udel.edu/tools/vsl_depend,
choosing the version for your OS type (32-bit linux,
64-bit linux, or 64-bit OS X).  Unzip and untar the
downloaded .tgz file and you will have a folder named "vsl".
If you do not already have a directory /opt, create one with
"mkdir /opt".  Move vsl into /opt.  Use sudo as needed.

3. Download the CIVL distribution from http://vsl.cis.udel.edu/civl.

4. Unzip and untar the downloaded file if this does not happen
automatically.  This should result in a folder named
CIVL-TAG, where TAG is some version id string.  This folder
contains the following:

 - README   : this file
 - bin      : containing one executable sh script called "civl"
 - lib      : containing civl-TAG.jar
 - doc      : containing the manual and the tutorial of CIVL
 - emacs    : CIVL-C emacs mode and its installation guideline
 - licenses : licenses for CIVL and included libraries
 - examples : some example CIVL programs

5. Move CIVL-TAG into /opt.

6. Put the civl script in your path however you like to put things
in your path.   Either move it to a directory in your path,
or create a symlink to it, or edit your .profile or equivalent
to put it in your path.

------------------------- Source Installation -------------------------

We recommend using the Eclipse IDE for Java/EE developers.

1. Install an SVN plugin in Eclipse (such as Subversive) if you have
   not already.

2. Install prerequisite projects ABC, SARL and GMC. 
   Make sure that the three projects are put in the workspace
   directory where CIVL will be put. 

    a. Install the symbolic algebra and reasoning library SARL.
           In Eclipse, select New Project...from SVN, use the archive 
           svn://vsl.cis.udel.edu/sarl. After entering that, open it 
           up and select the "trunk". After checking out trunk, name 
           the project "SARL". Then follow the instructions in the INSTALL 
           file for Eclipse installation. Build the sarl.jar from within 
           Eclipse by right-clicking (or ctrl-clicking) on the build.xml 
           file and selecting Run As->Ant Build.
           
    b. Install the C front-end ABC. In Eclipse, 
           select New Project...from SVN, use the archive 
           svn://vsl.cis.udel.edu/abc. After entering that, open it 
           up and select the "trunk". After checking out trunk, name 
           the project "ABC". Then follow the instructions in the INSTALL
           file for Eclipse installation. Build the abc.jar from within
           Eclipse by right-clicking (or ctrl-clicking on OS X) on the
           build.xml file and selecting Run As->Ant Build.
        
    c. Install the generic model checking utilities package GMC.
           In Eclipse, select New Project...from SVN, use the archive 
           svn://vsl.cis.udel.edu/gmc. After entering that, open it 
           up and select the "trunk". After checking out trunk, name 
           the project "GMC". Build the gmc.jar from within Eclipse
           by right-clicking (or ctrl-clicking) on the build.xml file and
           selecting Run As->Ant Build.

3. From within Eclipse, select New Project...from SVN. The archive is
   svn://vsl.cis.udel.edu/civl.  After entering that, open it up and
   select the "trunk". (It is simplest to just check out the trunk for
   the Eclipse project.)

4. Check out the trunk, and create the project using the New Java
   Project Wizard as usual, naming it "CIVL". The .project, .classpath,
   and other Eclipse meta-data are already in the SVN archive, saving you
   a bunch of work.

5. If you already have the VSL dependencies library, you may
   skip this step. Download the tgz archive of VSL dependencies from 
   http://vsl.cis.udel.edu/tools/vsl_depend, choosing the right .tgz 
   according to your platform:
        
        vsl_linux32-1.0.tgz     - 32-bit linux
        vsl_linux64-1.0.tgz     - 64-bit linux
        vsl_osx64-1.0.tgz       - 64-bit osx
        
   Unzip the .tgz file and you will have the folder vsl.
   Move vsl to /opt (you might need to use sudo for this.
   Also, if you don't already have a directory called /opt, 
   you will have to create it with mkdir /opt).

   Suppose that you put the .tgz file (or .tar file if your browser
   unzipped it automatically to a .tar file) in the directory $Download.
   You can use the following commands:

                $ cd $Download
                $ tar xzf YourTgzOrTarFile vsl
                $ sudo mv vsl /opt

   Now you can type "ls /opt/vsl", and the output should be

                README.txt    lib        licenses    src

6. If default_build.properties matches the configuration of your system,
   then you can skip this step. Otherwise, you may need to create a file 
   build.properties in the directory where build.xml is in.
   Copy and paste the content from any file under properties, edit each 
   entry with the path configured in your system. The newly created file
   build.properties will automatically be used by ant to to build the .jar file.

7. Navigate to Preferences -> Java -> Build Path -> ClassPath 
   Variables, and then select New to create a classpath variable VSL, 
   and specify its value to be /opt/vsl. Navigate to Preferences -> Run/Debug 
   -> String Substitution -> New, and then define an entry vsl_lib and 
   set its value to be /opt/vsl/lib.

8. Do a clean build.  Everything should compile.  Generate the civl.jar
   by right-clicking (or ctrl-click on OS X) the build.xml file and
   Run As->Ant Build.  

9. Go to Run->Run Configurations... Create a new JUnit configuration.
   Name it CIVL Tests. Select "Run all tests in the selected project..."
   and navigate to the folder "test" in the CIVL project.
   The Test runner should be JUnit 4. Under the Arguments tab, type
   "-ea" (without the quotes) in the VM arguments area (to enable assertion
   checking). Under the Environment tab, create an entry 
   DYLD_LIBRARY_PATH (OS X) or LD_LIBRARY_PATH (linux), 
   specify its value by clicking Variables and choose vsl_lib from the list, 
   or you may type ${vsl_lib} in the value entry.

10. An example of how to set up a single test from within Eclipse:
   create a new Run Configuration via the Run->Run
   Configurations... menu.  Create a new "Java Application"
   configuration.  Call it "CIVL barrier2".  The Project is CIVL.  The
   main class is edu.udel.cis.vsl.civl.CIVL.  Under the Arguments tab,
   set the Program arguments to "examples/barrier2.cvl" (without the
   quotes).  Modify the VM arguments and the Environment as in the step
   above.  You should now be able to run the test by clicking "Run".
