src/: ~21 capital-Foreign comments the case-sensitive verify grep missed (Foreign-class→Runtime-class, Foreign path→Runtime path, Foreign decls→Extern decls, FOREIGN function→extern function) across calls/inst/ffi_objc/jni_descriptor/emit_llvm/ c_import/lower.*/ops. src 'foreign' now = ONLY the hash_foreign token + 4 rejection messages (9.0-delete targets). examples/*.sx comments → extern/runtime-class (1219 stdout regen; KEPT 1176). docs/inline-asm-design + debugger purged. Comments only — no build impact. 9.0 ratified: DELETE hash_foreign token next.

// Regression: `obj.method()` runtime-class dispatch with a `float`
|
|
// return type used to silently emit `LLVMGetUndef` because the
|
|
// `Call<T>Method` switch in `emit_llvm.zig` didn't cover `.f32`.
|
|
// Combined with multiple such calls inlined as args to a single
|
|
// outer call (`f(o.a(), o.b(), o.c())`), every arg after the first
|
|
// went out as `undef` — exactly the chess Android touch failure
|
|
// (`MotionEvent.getX()` + `getY()` came through as `undef`s into
|
|
// `sx_android_push_touch`).
|
|
//
|
|
// This test exercises BOTH the `.f32` jdispatch slot AND the
|
|
// "multiple runtime-class method calls as args to one outer call"
|
|
// pattern. The bodies are gated behind a runtime-false flag so the
|
|
// JNI lookups never execute (no JVM in the test runtime), but the
|
|
// codegen path still has to emit the calls correctly.
