/* Tensilica's xt-xcc compiler is much more agressive at code
* optimization than gcc. Multiple __asm__ statements are
* insufficient for xt-xcc because subsequent optimization passes
* (beyond the front-end that knows of __asm__ statements and other
* such GNU Extensions to C) can modify the register selection for
* containment of C variables.
*
* xt-xcc cannot modify the contents of a single __asm__ statement, so
* we create single-asm versions of the syscall macros that are
* suitable and optimal for both xt-xcc and gcc.
*
* Linux takes system-call arguments in registers. The following
* design is optimized for user-land apps (e.g., glibc) which
* typically have a function wrapper around the "syscall" assembly
* instruction. It satisfies the Xtensa ABI while minizing argument
* shifting.
*
* The Xtensa ABI and software conventions require the system-call
* number in a2. If an argument exists in a2, we move it to the next
* available register. Note that for improved efficiency, we do NOT
* shift all parameters down one register to maintain the original
* order.
*
* At best case (zero arguments), we just write the syscall number to
* a2. At worst case (1 to 6 arguments), we move the argument in a2
* to the next available register, then write the syscall number to
* a2.
*
* For clarity, the following truth table enumerates all possibilities.
*
* arguments syscall number arg0, arg1, arg2, arg3, arg4, arg5
