* Add sample fuzzer which collects DrCov coverage for various architectures using QEMU instrumentation

* Fix clippy

* Rename NullCorpus to NopCorpus

* Added support for verbose output

* Attempt to fix clippy again

* Fix remaining defaults to use x86_64 when no arch specified and be more robust handling partial builds

* Make build even more robust against partial re-builds

* Added missing dependencies to workflow, updated README

* Add missing dependencies for i386

* Another dependency

* More dependencies

* Disable tests on OSX

* Add tmate

* Add missing dependencies and symlink header directory

* Tidy up after test so we don't hog all the disk space

qemu-coverage

This folder contains an example fuzzer which runs each entry in the input corpus and collects the cumuative coverage data in drcov format. This fuzzer also distributes the test cases in the input corupus evenly across the selected cores.

The following architectures are supported:

arm
aarch64
i386
x86_64
mips
ppc

Prerequisites

sudo apt install \
    gcc-arm-linux-gnueabi \
    g++-arm-linux-gnueabi \
    gcc-aarch64-linux-gnu \
    g++-aarch64-linux-gnu \
    gcc \
    g++ \
    gcc-mipsel-linux-gnu \
    g++-mipsel-linux-gnu \
    gcc-powerpc-linux-gnu \
    g++-powerpc-linux-gnu

Run

Defaults to x86_64 architecture

cargo make run

cargo make <arch>
