Mikhail, Now if you introduce one more level of indirection and start comparing Classes, not VTables, you do not need to enumerate.

Pavel, here is an example of the devirtualization: eax is an object reference: cmp eax,0 ; je 0131E778 ; mov ecx,dword ptr [eax] cmp ecx,13D5250h As you see JIT hardcodes vtable as a constant. If you move it - you have to enumerate it. All, Let's allow to Alexey to commit his code as it is and discuss unpinning with details in future? -- Mikhail Fursov
