Clang fails to warn about deprecated volatile-qualified return type

[siya100]

Code :

volatile struct amber jurassic();  // Should warn (deprecated) — Clang misses this
void trex(volatile short left_arm, volatile short right_arm);  // Clang warns (correct)
void fly(volatile struct pterosaur* pteranodon);  // OK (no warning expected)

Expected Behavior:
Clang should emit a deprecation warning (-Wvolatile or similar) for the volatile return type in jurassic(), just as GCC does

Actual Behavior:
Clang only warns about volatile parameters (e.g., trex) but silently accepts the deprecated volatile return type.
