[cDAC] Support API's used by CLRMD

[steveisok]

CLRMD with Unimplemented APIs

Total Implemented: 57 out of 112 (50.9%)

These APIs are called by CLRMD but not directly by any SOS command. Many managed-delegated SOS commands (!DumpHeap, !GCRoot, !EEHeap, !VerifyHeap, !FinalizeQueue, !ThreadPool, etc.) depend on these indirectly via CLRMD.

GC Heap / Sub-Heap Info

Used by DacHeap.CreateSubHeapInfo() — blocks !EEHeap, !DumpHeap, !FinalizeQueue, etc.

• ISOSDacInterface8::GetGenerationTable — GC generation table, workstation (HIGH)
• ISOSDacInterface8::GetGenerationTableSvr — GC generation table, server (HIGH)
• ISOSDacInterface8::GetFinalizationFillPointers — Finalization queue pointers, workstation (HIGH)
• ISOSDacInterface8::GetFinalizationFillPointersSvr — Finalization queue pointers, server (HIGH)

Handle Enumeration

• ISOSDacInterface::GetHandleEnumForTypes — Dependent handle enumeration via DacHeap.EnumerateDependentHandles() (HIGH)
