[fpc-devel] avr-embedded

[Michael Ring]

Here's an overview about important files, based on what I know from the 
arm/mipsel targets:

fpc/compiler/avr/cpuinfo.pas        //Here you add new controllers
fpc/compiler/systems/t_embed     //Linker scripts, new controllers need 
to also get added here
fpc/compiler/systems/i_embed     //I guess no changes are needed in this 
file

fpc/rtl/embedded/avr/                  //rtl directory for startup code 
and register definition unit(s)

fpc/rtl/embedded/rtl.cfg                //Here you define what will go 
into the rtl for avr. Add features that go into the rtl; codesize is an 
important thing to watch for. Not sure which units compile for avr.

fpc/rtl/embedded/Makefile.fpc       // When you add new controllers that 
need new register definitions than you will need to add the unit to the 
makefile.fpc and then run fpcmake
