+// Phase 1 step 1.4 (PLAN-FFI.md): multiple `#objc_call` sites
+// with the same selector. Today (after 1.3) each site emits its
+// own `call @sel_registerName(<"init">)`; the actual SEL handle
+// is recomputed per call.
+//
+// 1.5 lands selector interning: one static `SEL` global per
+// unique selector string (named `OBJC_SELECTOR_REFERENCES_init`,
+// matching clang's convention) populated once via the runtime
+// at module init. Per call site becomes a single load.
+//
+// Runtime behavior is unchanged before vs. after 1.5; the
+// improvement is visible in `sx ir` only. After 1.5 we should
+// see exactly one `sel_registerName` call per unique selector
+// string in the emitted IR — verify with:
+//
+//   ./zig-out/bin/sx ir examples/ffi-objc-call-03-selector-sharing.sx \
+//       | grep -c "call ptr @sel_registerName"
