100/100 regression tests pass (+ffi-objc-call-02-void-return xfail snapshot). The intrinsic with no `inline if false` guard reaches sema/codegen and trips an "unresolved: 'unknown_expr'" — the FfiIntrinsicCall AST node from Phase 1.1 has no lowering rules in lower.zig / emit_llvm.zig yet. nil receiver was chosen so the test doesn't need a real Obj-C object graph: the runtime guarantees `[nil msg]` is a no-op with zero result for void returns. macOS-gated via `inline if OS == .macos` so the runner stays portable. Next commit: emit_llvm.zig produces the per-call-site %sel = call ptr @sel_registerName(ptr "init.0") call void @objc_msgSend(ptr null, ptr %sel) lowering. Snapshot flips to "ok". Selector interning (one shared global per unique selector string) lands as a separate step (1.5).

// Phase 1 step 1.3 (PLAN-FFI.md): smallest end-to-end `#objc_call`.
|
|
// Void return, nil receiver — Obj-C runtime guarantees that messages
|
|
// to nil are no-ops with a zero result, so we don't need to set up
|
|
// a real object graph to exercise the lowering surface.
|
|
//
|
|
// Today (step 1.3, test-add): codegen rejects the FfiIntrinsicCall
|
|
// AST node. Snapshot pins the failure mode.
|
|
// Next (step 1.3, make-green): emit_llvm.zig synthesizes
|
|
// %sel = call ptr @sel_registerName(ptr @"sel:init")
|
|
// call void @objc_msgSend(ptr null, ptr %sel)
|
|
// per call site (no selector interning until step 1.5).
