If you mean something like:
```
// SFrame.h
extern ArrayRef<EnumEntry<sframe::BaseReg>> BaseRegisters;
// SFrame.cpp
static constexpr EnumEntry<sframe::BaseReg> BaseRegs[] = ...
ArrayRef<EnumEntry<sframe::BaseReg>> BaseRegisters = BaseRegs;
```
then I believe that should work (without creating new global constructors or anything). I did it this way because that's how this is implemented elsewhere (BinaryFormat/DXContainer.h, DebugInfo/CodeView/EnumTables.h)
