> Yeah, this makes no sense whatsoever.  The base is the array.  Your fix makes it so that every array access becomes a generic access (i.e. function call).  It defeats the whole purpose of having an optimizing compiler.

But.. there is already if (!isInt32Speculation(index)), so if any index is not int32, it becomes a generic access, I think it is wrong.
I hope that I have misunderstood about that. But I am curious abot that. Plz teach me.

And there is another review requests on https://bugs.webkit.org/show_bug.cgi?id=117281, Does anyone can review that? Thanks.
