Description JF Bastien 2017-02-21 14:02:17 PST
Repatch's assembly dump assumes there's a CodeBlock present. WebAssembly doesn't have one. It crashes.

I think you should make it easier to say this, since we say it in multiple places.  In fact, the usual dumping style for CodeBlock+CodeOrigin is:

dataLog(pointerDump(codeBlock), " ", codeOrigin)

I think that's what we want here as well.  But maybe we can take it a step further and create a helper for it.  The right way to go is something like:

dataLog(FullCodeOrigin(codeBock, codeOrigin))

Where FullCodeOrigin is a simple value class that holds a CodeBlock* and a CodeOrigin, and has a `void dump(PrintStream&) const` that prints them out.

Add a helper class as Fil suggested, and use it in a bunch of places. This is nice.
