SCRIPTS:
run.sh - This is the driver for automated testing.
To run: ./run.sh stpdirectory c_binaries_directory
Result: log/timestamp.log discerpancy report
ctostp.sh - This script generates corresponding stp probe script
files for every C file found in the input directory.
To Run: ctostp.sh input output where input is the
directory containing the C files to convert. Output
is the directory to store the corresponding stp
files.
build.sh - This script expedites the process of compiling all
of the c files. When the "compile" flag is given
it creates a directory called bin, which stores the
compiled C programs. ./build.sh clean removes the
binaries, and ./build.sh run attempts to execute all
of the programs in cfiles/bin.
