I think it's a good start. Some minor nits:

+const char *
+symtab_node::dump_visibility () const

+ = { "default", "protected", "hidden", "internal" };
+ return visibility_types[DECL_VISIBILITY (decl)];
+}
+
+/* Dump the type_name of the symbol. */
+const char *
+symtab_node::dump_type_name () const
+{
+ return symtab_type_names[type];
+}
Both method names are not very good. I guess the first
should be get_visibilitiy_string and the second
get_symtab_type_string? Because they do not actually
dump.
For the function statistics I wonder if we really need the
untransformed body or if we can resort to inline information
that must be also in the LTO stream.
Otherwise looks OK to me.
Thanks,
Richard.
