I think that's accurate. Example code:
static privileged int GetPid(void) {
int res;
#ifdef __x86_64__
asm volatile("syscall"
: "=a"(res)
: "0"(__NR_linux_getpid)
: "rcx", "r11", "memory");
#elif defined(__aarch64__)
register long res_x0 asm("x0");
asm volatile("mov\tx8,%1\n\t"
"svc\t0"
: "=r"(res_x0)
: "i"(__NR_linux_getpid)
: "x8", "memory");
res = res_x0;
#endif
return res;
}
You should be fine.
