--- Comment #2 from Reid Kleckner <rnk at google.com> ---
I think this is working as intended for now. We reject these parameter usages
up front:

t.cpp:34:13: error: parameter references not allowed in naked functions
      , "l"(aSignal), "l"(aInfo), "l"(aContext)
            ^
t.cpp:19:16: note: attribute is here
__attribute__((naked)) void
               ^

It's not as helpful as we could hypothetically be, but at least the user knows
what to do: refer to the parameters manually by register or memory location.
