first_nested_function()

cgraph_node * first_nested_function ( cgraph_node * node )

inline

If there are functions nested in NODE, return first one.

insert_field_into_struct()

void insert_field_into_struct ( tree type, tree field )

lower_nested_functions()

void lower_nested_functions ( tree fndecl )

extern

Main entry point for this pass.  Process FNDECL and all of its nested
subroutines and turn them into something less tightly bound.

maybe_record_nested_function()

void maybe_record_nested_function ( cgraph_node * node )

If NODE is nested function, record it.

nested_function_origin()

cgraph_node * nested_function_origin ( cgraph_node * node )

inline

Return origin of nested function (and NULL otherwise).

next_nested_function()

cgraph_node * next_nested_function ( cgraph_node * node )

unnest_function()

void unnest_function ( cgraph_node * node )

extern

cgraph_node is no longer nested function; update cgraph accordingly.
