 233         using ctf_lookup_symbol_idx in non-writable dicts.  Special-case
 234         name lookup in dynamic dicts without reported symbols, which have
 235         no symtab or dynsymidx but where name lookup should still work.
 236         (ctf_lookup_by_symbol_name): New, another wrapper.

 245         (ctf_arc_lookup_sym_or_name): ... this.  No longer cache
 246         ctf_id_t lookups: just call ctf_lookup_by_symbol as needed (but
 247         still cache the dicts those lookups succeed in).  Add
 248         lookup-by-name support, with dicts of successful lookups cached in
 249         ctfi_symnamedicts.  Refactor the caching code a bit.
 250         (ctf_arc_lookup_symbol_name): New, another wrapper.

 254         * testsuite/libctf-lookup/enum-symbol.c (main): Use
 255         ctf_arc_lookup_symbol rather than looking up the name ourselves.
 256         Fish it out repeatedly, to make sure that symbol caching isn't
 257         broken.
 258         (symidx_64): Remove.
 259         (symidx_32): Remove.
 260         * testsuite/libctf-lookup/enum-symbol-obj.lk: Test symbol lookup
 261         in an unlinked object file (indexed symtypetab sections only).

 263         (try_maybe_reporting): Check symbol types via
 264         ctf_lookup_by_symbol_name as well as ctf_symbol_next.
 265         * testsuite/libctf-lookup/conflicting-type-syms.*: New test of
 266         lookups in a multi-dict archive.
