-/* 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.
