I had doubt whether in "unit-at-time mode" call graph is built incrementally or is it built
only after all the funcitons have been parsed (i.e. after cgraph_finalize_compilation unit functions is called). In the latter case, where are all the function trees stored then ? I
presume that cgraph nodes are allotted to respective functions (and trees stored there) and
only call and return edges are fixed after all funcitons are ready with
their trees.
Could someone please clarify on this?
Thanks and Regards. Virender
