I assume that you are referring to the tree nodes in the compiler.  Such a 
feature does not exist.

To understand how the tree is processed node by node, look at the parser 
(cs_grammar.y or c_grammar.y) for the language construct in question.  Then 
grep the *.tc files for that node name to see the other passes for that node.

Yes, the documentation for the compiler design is sparse.  I recommend 
starting with the treecc documentation to familiarise yourself with the 
paradigm.  Then move on to "cg_nodes.tc", and the other files in "codegen".  
You should then have a basic understanding.  Also look at "cscc/HACKING", 
which describes the plugin mechanism.

Cheers,

Rhys.
