thanks, i made that change and the syscall is working now.  i also switched to 
using out0/etc... rather than named registers since it looks cleaner (and is 
probably the "right" thing anyways).

        /* Maybe it's an alternative signal stack.  */          \
        adds out1 = -sizeSS, r12;                               \
        mov out0 = r0;                                          \
        ;;                                                      \
        mov r12 = out1;                                         \
        DO_CALL_VIA_BREAK (SYS_ify (sigaltstack));              \
        ;;                                                      \
