"Operands to OpPtrEqual, OpPtrNotEqual, and OpPtrDiff must not be pointers into the PhysicalStorageBuffer storage class."

Is this a misprint? How else do I compare these pointers?

Feature request:
Enable OpPtr[Not]Equal, OpPtrDiff and proper signed indexing for OpPtrAccessChain and OpAccessChain for physical storage buffer pointers. These are the only true pointers in SPIR-V graphics, and they should have actual pointer ops.
