I believe that we can help you with resolution with FPC if you're 
interested, it isn't that difficult after all. Building a trunk (main) 
compiler, rtl and packages is matter of several rather simple commands 
if you already have your FPC 3.2.2 installation, plus installation of an 
external package (LLVM). All of it rather feasible. Yes, you may 
possibly encounter some issues with the current port to this target 
(aarch64-win64), but I'm sure there are others willing to help with that 
part as well if you report such issues. Just let me/us know if you want 
to continue that way, I'm willing to provide more specific directions.
