A llvm backend is surely doable especially if you can get an AST out of FPC.

But they do their job as you ask it...
The job I am asking for is porting Delphi software to different CPU
architectures. If the tool level is not as high as FPC can provide, I
can redo the code in C as just as well.

Not at all, rather the contrary, as far as I know.

Hi Compiler developers.

While I do all PC projects (for Windows and Linux) in Object Pascal,
