// Assembly code for making x86-64 syscalls.
//
// x86-64 syscall argument register ordering is the same as the x86-64
// userspace argument register ordering except that a3 is passed in r10
// instead of rcx, and the syscall number (nr) is passed in eax.
//
// outline.rs takes care of reordering the nr argument to the end for us,
// so we only need to move nr into eax and move rcx into r10 as needed.
//
// x32 is not yet supported.
