&gt; Slow (but clean) patch
&gt; 
&gt; View in context:
&gt; <a href="https://bugs.webkit.org/attachment.cgi?id=251211&amp;action=review">https://bugs.webkit.org/attachment.cgi?id=251211&amp;action=review</a>
&gt; 
&gt; It's surprising that this patch is a slow-down. :-/
&gt; 
&gt; &gt; Source/JavaScriptCore/dfg/DFGWatchpointCollectionPhase.cpp:116
&gt; &gt; -        case AllocationProfileWatchpoint:
&gt; &gt; -            addLazily(m_node-&gt;castOperand&lt;JSFunction*&gt;()-&gt;allocationProfileWatchpointSet());
&gt; &gt; +        case AllocationProfileWatchpoint: {
&gt; &gt; +            InlineWatchpointSet* watchpointSet = m_node-&gt;castOperand&lt;JSFunction*&gt;()-&gt;allocationProfileWatchpointSet();
&gt; &gt; +            // If we reach this point, the function's rare data was allocated when the AllocationProfileWatchpoint
&gt; &gt; +            // was added to the graph. We never de-allocate the rare data, so it must still be present, and the
&gt; &gt; +            // allocationProfileWatchpointSet with it.
&gt; &gt; +            ASSERT (watchpointSet);
&gt; &gt; +            addLazily(*watchpointSet);
&gt; &gt;              break;
&gt; &gt; +        }
&gt; 
&gt; It would be better to remove the AllocationProfileWatchpoint node in this
&gt; patch, and do the watchpoint set registration in ByteCodeParser.</span >

I thought we said we shouldn't do this?
