Intro

go114-fuzz-build is a mostly-drop-in replacement for go-fuzz-build's -libfuzzer build mode, but uses cmd/compile's native libfuzzer instrumentation (included experimentally since Go 1.14) instead of source-to-source transformation.

Example

1. Install go114-fuzz-build:

$ go get -u github.com/kyakdan/go114-fuzz-build

2. Build Kubernetes fuzz target with go114-fuzz-build and link against libFuzzer:

$ git clone --depth=1 git clone --depth 1 https://github.com/kubernetes/kubernetes.git
$ cd kubernetes
$ go114-fuzz-build -o yaml_FuzzSigYaml.a -func FuzzSigYaml ./test/fuzz/yaml
$ clang -o yaml_FuzzSigYaml yaml_FuzzSigYaml.a -fsanitize=fuzzer
