--- Comment #2 from Iain Buclaw <ibuclaw at gdcproject dot org> ---
@register attribute has been added, meaning that you can now have the follo=
wing
as an alternative to your example.

---
import gcc.attributes : register;

@register("rax") SYSCALL rax =3D ident; // rax - syscall number
@register("rdi") size_t rdi =3D arg1;   // rdi - arg1
@register("rsi") size_t rsi =3D arg2;   // rsi - arg2
@register("rdx") size_t rdx =3D arg3;   // rdx - arg3
@register("r10") size_t r10 =3D arg4;   // r10 - arg4
asm @nogc nothrow {
  "syscall"
  : "=3Dr" (rax)
  // inputs:
  : "r" (rax),
    "r" (rdi),
    "r" (rsi),
    "r" (rdx),
    "r" (r10),
    "m"( *cast(ubyte*)arg1)   // "dummy" input instead of full memory clobb=
er
  // clobers
  : "rcx", "r11";  // Clobers rax, and rcx and r11.
}
return rax;
