clr/src/vm/appdomain.cpp pre-allocates some exceptions in
SystemDomain::CreatePreallocatedExceptions() by calling CreateHandle()
then StoreObjectInHandle(). They boil down into calls to
clr/src/vm/objecthandle.cpp. The GC calls objecthandle.cpp's
Ref_TraceNormalRoots() from within CNameSpace::GcScanHandles() in
gcscan.cpp, to enumerate these objects.
For strings, clr/src/vm/appdomain.cpp's SystemDomain::Init() constructs
a thing called the GlobalStringLiteralMap. See
clr/src/vm/stringliteralmap.cpp for its implementation details. It
looks like the m_LargeHeapHandleTable is implemented in appdomain.cpp.

Subject: [DOTNET-ROTOR] Rotor root set enumeration question.
Does anybody know how Rotor enumerates the roots for
things like preallocated exceptions and especially for
string literals? String literals seem to be allocated
through the GC memory allocation routines but I don't
see where/how those roots are enumerated at collection
time.
thanks,
Todd
