--- Comment #5 from Xi Ruoyao <xry111 at gcc dot gnu.org> ---
Is this a bug?
-ffixed-reg
Treat the register named reg as a fixed register; generated code should never
refer to it (except perhaps as a stack pointer, frame pointer or in some other
fixed role).
To me "the ABI mandates to pass an argument in this register" means "some other
fixed role".
