AVR

General information

The FPC-AVR port is currently experimental and non working. It uses the GCC AVR tool chain and will be compatible with GCC regarding calling conventions etc.

Implementation details

FPC considers AVR being a 16 bit CPU. So the type tregister actually describes a register pair being the second register implicitly named.
