Move examples/*.sx and their expected/ snapshots into per-category subfolders (examples/<category>/...). Folder = leading filename token, with ffi-objc/ffi-jni kept whole; filenames are unchanged. The corpus runner and LSP sweep now discover each category's expected/ dir, while issues/ stays flat. Example 1058's repo-root-relative companion import is made file-relative. Path strings embedded in 164 snapshots were regenerated (path-only changes). Test-layout docs in CLAUDE.md updated.

// Phase 1 step 1.15 (PLAN-FFI.md): `#jni_call(void)` codegen.
|

//
|
|
// `#jni_call(T)(env, target, "method_name", "(Sig)RetSig", args...)`
|
|
// dispatches a JNI instance-method call. The lowering hand-emits the
|
|
// vtable indirection:
|
|
//
|
|
// ifs = *env // JNINativeInterface*
|
|
// cls = ifs->GetObjectClass(env, target)
|
|
// mid = ifs->GetMethodID(env, cls, name, sig)
|
|
// ifs->Call<Type>Method(env, target, mid, args...)
|
|
//
|
|
// Phase 1.17 introduces method-ID caching via static slots populated
|
|
// at module-init; this step keeps the per-call-site lookup.
|
|
//
|
|
// Host can't dlopen libjvm via the JIT, so the JNI body is gated
|
|
// behind `inline if OS == .android`. The macOS test path strips the
|
|
// body and prints "skipped"; the cross_compile.sh Android target
|
|
// verifies that the gated body actually compiles + links against
|
|
// libjvm in the Android sysroot.
