@ -11,12 +11,15 @@ A tool to check for non-determinism in fuzz coverage. To get the help, run:
RUST_BACKTRACE=1 cargo run --manifest-path ./contrib/devtools/deterministic-fuzz-coverage/Cargo.toml -- --help
```
To execute the tool, compilation has to be done with the build options
`-DCMAKE_C_COMPILER='clang' -DCMAKE_CXX_COMPILER='clang++'
-DBUILD_FOR_FUZZING=ON -DCMAKE_CXX_FLAGS='-fPIC -fprofile-instr-generate
-fcoverage-mapping'`. Both llvm-profdata and llvm-cov must be installed. Also,
the qa-assets repository must have been cloned. Finally, a fuzz target has to
be picked before running the tool:
