+General:
+- Use custom __builtin_offsetof definition to preserve the call until lower gimple
+
+Approach:
+- At the very last point of gimple (after gimple optimizations), recognize accesses
+	- Build a mapping of statement location (multiple statements share) to a semantic graph (or tree)
+- Right after expansion to RTL, pattern match set of RTL instructions with same location to graph
+	- Add notes (persistent over RTL transformations) to any RTL instruction that is relevant
+- After all RTL optimizations, add assembly labels before relevant RTL instructions (identified by notes)
