Passes for a new porting

["gabriele" <gabriele at caracausi dot it>]

Hello All! 

This question is for people who made a porting to a new target.
Probably this is a stupid question but I have this doubt. 

I'm working on the porting of a new target and I've read many other portings 
of architectures similar to mine. 

I've looked that many of these portings are very complex (file .md) and this 
thing scared me but probably these are the result of many months or years of 
hard working. 

So if I want to port to a new target initially have I to refear only to 
standard documents (i.e. original GCC documentation) without scaring me of 
the complexity of existent portings? 

This strategy'll direct me to success in my project? 

Thanks all.
