[llvm-dev] Way to know if an Operand of a SelectionDAG is a pointer

[Alexandre Ghiti via llvm-dev]

Hi everyone,

We developed a new backend for our architecture based on LLVM 3.8, I'm 
sorry about that, I quite understand if my questions do not get any 
answers because of that.

We have some instructions that allow to protect pointers that sit in our 
small scratch-area.

I did not find a way to know, when selecting the machine instructions, 
if one of the operands of the SDNode is a pointer. Do you know how I 
could get this info ?

Thanks for your time,

Alex
