Basically, yes.  However, variables declarations are typically handled 
separately from the expression, so if you want to retain info about 
variables, you need to do it elsewhere, when the variable's DECL_RTL is 
generated.  Globals are handled differently than locals, but probably 
only globals matter, in which case you should see make_decl_rtl and 
encode_section_info.

Also, note, in current sources, this stuff is all different, because the 
tree to RTL expander has been replaced with tree to gimple to RTL 
expander.  So what you are doing is probably of no long term use.
