SuperC is a parsing framework that preserves preprocessor conditionals during C preprocessing and parsing. SuperC is bundled with the xtc framework, from which it uses the AST and Type libraries. The original project homepage for both can be found at http://www.cs.nyu.edu/xtc/, where past versions and links to publications can be found.

Dependencies and environment variables

Building SuperC requires bison, libz3-java, libjson-java, and sat4j. For debian and ubuntu run

apt-get install bison libz3-java=4.8.7-4build1 libjson-java sat4j

The following environment variables are expected by SuperC/xtc, changing /path/to/repository/ to the root of the repository.

JAVA_DEV_ROOT=/path/to/repository/  # wherever your git repo is cloned
# add included libraries to the classpath
CLASSPATH=$CLASSPATH:$JAVA_DEV_ROOT/classes:$JAVA_DEV_ROOT/bin/junit.jar:$JAVA_DEV_ROOT/bin/antlr.jar:$JAVA_DEV_ROOT/bin/javabdd.jar:$JAVA_DEV_ROOT/bin/json-simple-1.1.1.jar
# add system-installed libraries to the classpath
CLASSPATH=$CLASSPATH:/usr/share/java/org.sat4j.core.jar:/usr/share/java/com.microsoft.z3.jar:/usr/share/java/json-lib.jar
JAVA_ARGS="-Xms2048m -Xmx4048m -Xss128m" # JVM settings
JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/  # Location of java jdk
export JAVA_DEV_ROOT CLASSPATH JAVA_ARGS JAVA_HOME

Building SuperC and xtc

From the root of the xtc source tree, run the following:

make configure
make

Running the SuperC parser

java superc.SuperC -silent -printAST file_to_transform.c

Running the SugarC preprocessor desugarer

java superc.SugarC file_to_desugarer.c > desugared_file.c

Running the SuperP4 parser

java superc.SuperP4 -silent -printAST file_to_transform.p4

Testing SuperC's parser

First set SUPERC_SCRATCH=~/tmp/superc to some existing directory for holding temp files.

The, from the root of the source tree, run

make check-cpp  # run SuperC tests

Using SuperC with Linux source code

Use the script scripts/superc_linux.sh. See scripts/data.sh for example usage. (Linux versions past 2013 have not been tested.)

Regenerating SuperC's parsers for development

SuperC comes shippped with prebuilt parsers. To modify then generate

make -C src/superc parsers
make

SuperC Manual

Run make manual in src/superc/manual. Requires pdflatex. SuperP4 is similar to SuperC, so the manual applies to SuperP4 as well.

Kmax

Kmax is now in its own repository: https://github.com/paulgazz/kmax
