What we need here is a per-function symbol table. I don't think I mind if we put it together with each cgraph node or in a separate symbol table section indexed by node id. Both seem reasonable. Though I'm curious why you think storing it in the cgraph node directly is not a good idea. What each function needs to be write to this table is every symbol in gimple_referenced_vars(fn) that is marked as is_global_var(). I suppose that this table only needs to have the references to the table stored in DECL_SECTION on the output file. > We have a pass that computes this info currently, the ipa_referenced vars, You mean pass_ipa_reference()? But this is the pass that sets read/written attributes from file-globals isn't it? Diego.
