(easiest is to just fpc -va some dummy source and then grep for CPU, or look
in the compiler sources (options.pas or systems/ iirc)
You can select a different cpu then the default using fpc -P<architecture>
So if you have a x86 compiled fpc.exe, you can get it to select ppcx64 using
fpc -Px86_64 and then e.g. -Twin64 for the target. Then all the relevant
directives (CPU64, cpux86_64, win64, mswindows etc) are defined.
(I use windows now because I know those defines by heart, for arm it is the
The buildfaq (document section on the FPC site), though somewhat outdated,
has some info and examples on this.
