# Assembly code for making riscv64 syscalls.
#
# riscv64 syscall argument register ordering is the same as the riscv64
# userspace argument register ordering except that the syscall number
# (nr) is passed in a7.
#
# nr_last.rs takes care of reordering the nr argument to the end for us,
# so we only need to move nr into a7.
