13 JNI examples migrated (1410-1419/1423/1424/1425): import runtime classes
'#foreign #jni_class("X") {' → '#jni_class("X") extern {'. 1417 (all-runtimes)
also exercises #jni_interface/#objc_class/#objc_protocol/#swift_class/#swift_struct/
#swift_protocol — all take the postfix modifier (verified by probe), migrated via a
generalized '#foreign #<directive>("X") {' → '… extern {' rewrite. No 14xx snapshot
asserts on 'foreign'; empty snapshot diff, corpus-validated.
KEPT comment-only #foreign in 1426 (jni-extern-class test, no decls). Suite green
(647 corpus / 444 unit, 0 failed).

// Regression: `obj.method()` foreign-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 foreign-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.
