 202         (ctf_lookup_symbol_name): Remove.
 203         * ctf-lookup.c (ctf_lookup_symbol_name): Propagate errors from
 204         parent properly.  Make static.
 205         (ctf_lookup_symbol_idx): New, linear search for the symbol name,
 206         cached in the crossdict cache's ctf_symhash (if available), or

 209         (ctf_lookup_by_symbol): Turn into a wrapper around...
 210         (ctf_lookup_by_sym_or_name): ... this, supporting name lookup too,
 211         using ctf_lookup_symbol_idx in non-writable dicts.  Special-case
 212         name lookup in dynamic dicts without reported symbols, which have
 213         no symtab or dynsymidx but where name lookup should still work.
 214         (ctf_lookup_by_symbol_name): New, another wrapper.
 215         * ctf-archive.c (enosym): Note that this is present in

 222         (ctf_arc_lookup_symbol): Turn into a wrapper around...
 223         (ctf_arc_lookup_sym_or_name): ... this.  No longer cache
 224         ctf_id_t lookups: just call ctf_lookup_by_symbol as needed (but
 225         still cache the dicts those lookups succeed in).  Add
 226         lookup-by-name support, with dicts of successful lookups cached in
 227         ctfi_symnamedicts.  Refactor the caching code a bit.
 228         (ctf_arc_lookup_symbol_name): New, another wrapper.
 229         * ctf-open.c (ctf_dict_close): Free the ctf_symhash.

 232         * testsuite/libctf-lookup/enum-symbol.c (main): Use
 233         ctf_arc_lookup_symbol rather than looking up the name ourselves.
 234         Fish it out repeatedly, to make sure that symbol caching isn't
 235         broken.
 236         (symidx_64): Remove.
 237         (symidx_32): Remove.
 238         * testsuite/libctf-lookup/enum-symbol-obj.lk: Test symbol lookup
 239         in an unlinked object file (indexed symtypetab sections only).
 240         * testsuite/libctf-writable/symtypetab-nonlinker-writeout.c
 241         (try_maybe_reporting): Check symbol types via
 242         ctf_lookup_by_symbol_name as well as ctf_symbol_next.
 243         * testsuite/libctf-lookup/conflicting-type-syms.*: New test of
 244         lookups in a multi-dict archive.

 320         (ctf_serialize): Handle the !LCTF_LINKING case by writing out an
 321         indexed, sorted symtypetab (and allow SYMFP to be NULL in this
