Purpose of print_node() function (defined in gcc/print_tree.c)

[George Kakol]

Hi,

Can someone tell what is this function for? I actually found it useful
for my needs (to have the capability to take a look on parsed source
tree and possibly convert it to some other format), however I can't find
the place it's being called from (except from stor-layout.c and
c-decl.c). And I have no clue how to force gcc to make this call
actually happening.

George.
