[fpc-devel] register calling convention for Apple M1 ?

Trying to get the IDE lldb based debugger to work on M1....
But I don't have M1 myself, so ...
procedure fpc_Raiseexception (Obj : TObject; AnAddr : CodePointer;
AFrame : Pointer); compilerproc;
is entered, the IDE tries to get the arguments. In normal user installs
this code has no debug info, though the IDE relies on knowing the
register for each of he arguments?
I do hope that the call on M1 also uses registers. If so, can anyone
tell me which registers?
Obj: On 64bit-Intel Linux that is RDI (Win64: RCX)
AnAddr: On 64bit-Intel Linux that is RSI (Win64: RDX)
AFrame: On 64bit-Intel Linux that is RDX (Win64: R8)
Anything similar on M1?
