// Flags: --allow-natives-syntax --turbo-optimize-apply --opt
// These tests do not work well if this script is run more than once (e.g.
// --stress-opt); after a few runs the whole function is immediately compiled
// and assertions would fail. We prevent re-runs.
// Flags: --nostress-opt --no-always-opt
// The test relies on optimizing/deoptimizing at predictable moments, so
// it's not suitable for deoptimization fuzzing.
// Flags: --deopt-every-n-times=0
// Tests for optimization of CallWithSpread and CallWithArrayLike.
// This test is in a separate file because it invalidates protectors.
// Test with array prototype modified after compilation.
