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.

// `xx @<extern_global>` round-trips through a non-main helper
|
|
// function: the helper's `xx @__stdinp` cast lowers to a `bitcast`
|
|
// IR opcode that emit_llvm.zig dispatches to `LLVMBuildPtrToInt`
|
|
// (BitCast doesn't accept ptr↔int on modern LLVM with opaque
|
|
// pointers), and a `u64`-returning function correctly returns
|
|
// the address.
|
|
//
|
|
// Was issue-0037 — the helper used to emit `ret i64 undef` because
|
|
// `coerceToType` had no pointer↔integer case, so the explicit
|
|
// `xx ptr` cast produced an unchanged pointer value handed to a
|
|
// `ret i64` slot.
