I am not 100% sure what precisely you need, but if you need just hashtable translating strings to integers, you can probably just follow section_name_hash in symtab.cc which is doing pretty much the same. In case you can already rely on the fact that the strings are unified (which is the case for GCC's identifiers) you can also simply use hash_map<tree,unsigned_int> which has bit easier to set up.
