For the original Cannoli readme, check here.

Cantrace

Cantrace is a coverage tracer that runs really fast! It uses Cannoli (which it's forked from...we'll work on that) to get coverage information of all branches in one or more executions of a program and output it as (for now...) JSON. It works on x86_64 only for now, although there is no reason it won't work on other architectures once objects and disassembly are taken care of.

Building

First we need to build cannoli and the jitter library:

cargo +nightly build --release

Then you can build cantrace:

cd cantrace
cargo +nightly build

Running

cd cantrace
cargo +nightly run

You probably want to pass args though, to do that you'd do something like:

cd cantrace
cargo +nightly run -- \
   -i ./tests/inputs/poll_AIS-Lite_0.poll \
   -j ../target/release/libjitter_always.so \
   -l ./tests/libs/ \
   -q ./tests/bundles/qemu/exodus/bin/qemu-x86_64 \
   -t 4 \
   ./tests/bins/AIS-Lite-pie
