Hi @nikic ,
So your proposal will be to change this 
enum class InaccessibleTargetMemLocation {
  AARCH64_FPMR = 3,
  AARCH64_ZA = 4,
};
To be something like
enum class InaccessibleTargetMemLocation {
  TargetMemLoc1= 3,
  TargetMemLoc2 = 4,
  ....
};

The printing of _**memory(target1: /*aarch64.fpmr*/ read)**_ is happening in the file Attributes.cpp  and that is the part I may lack understanding of how to link this with the target architecture. I will need to add a Target hook in that part of the code, but atm there is not information about the target.
