// Phase 1 step 1.14 (PLAN-FFI.md): `#objc_call` inside an
// `inline if OS == .ios { ... }` arm cross-compiles cleanly to
// Android. The comptime gate must strip the arm BEFORE the
// `objc_msg_send` lowering runs, otherwise emit_llvm would
// produce calls to `@objc_msgSend` / `@sel_registerName` that
// don't exist in Bionic + libGLESv3 / linker would fail.
//
// On macOS the iOS arm is also stripped (we're not iOS) so the
// runtime test just prints "host stripped both", proving the
// `inline if OS == { case }` form works around `#objc_call`
// sites the same way it does elsewhere.

#import "modules/build.sx";

// Empty stub class — Android cross-compile requires a `#jni_main`
// declaration to satisfy the entry-point check. This file is testing
// `inline if OS` gating around `#objc_call`, not Activity wiring.
