# Build the vortex-fuzz crate for wasmfuzz

#

# This script builds the fuzzer binary for the wasm32-wasip1 target,

# which can then be used with wasmfuzz for coverage-guided fuzzing.

#

# Prerequisites:

# - Nightly Rust toolchain (for -Z flags)

# - wasm32-wasip1 target: rustup +nightly target add wasm32-wasip1

# - wasmfuzz: cargo install --git https://github.com/CISPA-SysSec/wasmfuzz

#

# Usage:

# ./build-wasmfuzz.sh

#

# After building, run with wasmfuzz:

# wasmfuzz fuzz --timeout=1h --cores 8 --dir corpus/ \

# target/wasm32-wasip1/release/array_ops_wasm.wasm
