// Regression: when a `#jni_call` method returns a type the
// `Call<T>Method` switch in `emit_llvm.zig` can't dispatch
// (anything outside void/bool/i32/i64/f32/f64/pointer), the
// compiler must emit a DIAGNOSTIC at lower time rather than
// silently producing `LLVMGetUndef` at codegen time. Without
// this guard, the chess Android touch bug shipped: an
// unsupported return type silently became `undef` and showed
// up as garbage arguments downstream.
//
// Here we declare a JNI method returning `i8` (jbyte, not yet
// wired into the call-method switch). The compile must fail
// with a clear message naming the method + return type.
