While this is technically a violation of WebKit style I think its are warranted in this case. The case is surrounded by other checks that the result of similar expressions are equal to non-zero values. Using ! instead just makes the code harder to read.

r=me if you resolve the question about the Signature vector in WASMModuleParser.h.

/much/more/ or /much/much more/

> Source/JavaScriptCore/wasm/WASMModuleParser.h:61
> +    Vector<FunctionInformation> m_functions;
> +    Vector<Signature> m_signatures;

FunctionInformation embeds a Signature.  Why do we need this separate Signature Vector?  I also don't see it used anywhere.

Please fix the build failures too.

Fixed the build failure locally.

m_signatures owns the signatures used by FunctionInformation. It's likely that many functions all have the same signature so rather than duplicate that everywhere we just have each function point to a shared signature. You're right that it's not used in this patch. I'll delete them.

Ah.  I missed the detail that the signature in FunctionInformation is a Signature* and not the Signature itself.
