If I understood correctly you are using a modified arm simulator (not the V8 built-in one) to run V8, and this simulator returns "illegal instruction". V8 does not trap illegal instructions so the options I can think of: * your ARM simulator does not support ARMv7 with VFP, which is a requirement for V8 * your modification to V8 are corrupting code generation and the pc end up in some data. Did you try running the test on a clean version of V8?
