[LLVMdev] Accessing slot numbers of unnamed instructions (SlotTracker)

[florian.merz at kit.edu]

Hey everyone,

I'm currently trying to figure out a method for providing a unique 
identification of an llvm::Instruction that is consistent with the output of an 
AssemblyWriter. Obviously this is easy for named instructions: In this case 
the identification is the name itself, but I'd like to have the same thing for 
unnamed instructions.

If I understand the code in AssemblyWriter.cpp correctly, AssemblyWriter uses 
SlotTracker to keep track of the numbers used for unnamed instructions. 
Unfortunately for me SlotTracker is missing from LLVM's public header files. Is 
there any other way to retrieve a slot number for an Instruction that is 
consistent with the numbers assigned by an existing AssemblyWriter instance.

Best regards,
 Florian Merz
