data-symbols.py

Open an IR and print every symbol pointing to data.

#!/usr/bin/python
#
# An example program which opens an IR and prints information about all
# symbols pointing to data.
#
# To run this example, do the following.
#
# 1. Install the gtirb package from Pypi.
#
# 2. Run ddisasm to disassemble a binary to GTIRB.
#
#    $ echo 'main(){puts("hello world");}'|gcc -x c - -o /tmp/hello
#    $ ddisasm /tmp/hello --ir /tmp/hello.gtirb
#
# 3. Execute the following command to run the program on the
#    serialized GTIRB data.
#
#    $ ./doc/examples/data-symbols.py /tmp/hello.gtirb
