    12 is a lot of simultaneous registers to ask the compiler for given that it only ever really had 14 to start with after the stack-pointer and program-counter were deducted.
    The additional 2 registers may already be permanently allocated for stack limit, frame pointer, global table pointer or other purposes depending on the platform requirements.

    You really should consider whether what you are doing is appropriate for inline assembly vs either a naked function / standalone assembly file or using the intrinsics.
