build tree nodes vs expand as you go

[Fergus Henderson]

Hi,

I'm working on a new front-end. 

I'm trying to decide whether to build a gcc tree node for each
statement in my source language (like e.g. the Java front-end does),
or whether to just expand them directly, using expand_start_cond(),
expand_else(), expand_end_cond() etc.

What are the trade-offs here?

At first glance expanding them directly looks a little simpler,
but I'm worried I may be missing something...
