ILOffsetMap points to QuickJitted assembly code even after method has been Tier-1 compiled (.NET 7+) about clrmd HOT 1 CLOSED

Unfortunately, it looks like there is no runtime API for getting the IL to Native map from tiered JIT'ed code. At least, not in the API that ClrMD uses.

ClrMD calls into IXClrDataModule::GetILAddressMap, this is implemented in debug\daccess\task.cpp. The inner call that does this work is GetMethodNativeMap which does take the native address location, but we always pass 0 in GetILAddressMap because the shape of that COM API doesn't take in the native address value.

That means this would be a dotnet/runtime feature and not a ClrMD feature. Feel free to create a dotnet/runtime feature request for this. Without that feature I have to close this "Not Planned". I may end up marking the IL to Native map obsolete in the future since it's not supported for tiered JIT.

I believe ICorDebug will be the only place to get the correct IL to Native map, but I haven't investigated it there.

from clrmd.
