   1 # Assembly code for making mips64 syscalls.
   2 #
   3 # mips64 syscall argument register ordering is the same as the mips64
   4 # userspace argument register ordering except that the syscall number
   5 # (nr) is passed in v0.
   6 #
   7 # outline.rs takes care of reordering the nr argument to the end for us,
   8 # so we only need to move nr into v0.
