 174         (ctf_link_deduplicating_one_symtypetab): Use

 258         (ctf_lookup_by_sym_or_name): ... this, supporting name lookup too,
 259         using ctf_lookup_symbol_idx in non-writable dicts.  Special-case
 260         name lookup in dynamic dicts without reported symbols, which have
 261         no symtab or dynsymidx but where name lookup should still work.
 262         (ctf_lookup_by_symbol_name): New, another wrapper.

 271         (ctf_arc_lookup_sym_or_name): ... this.  No longer cache
 272         ctf_id_t lookups: just call ctf_lookup_by_symbol as needed (but
 273         still cache the dicts those lookups succeed in).  Add
 274         lookup-by-name support, with dicts of successful lookups cached in
 275         ctfi_symnamedicts.  Refactor the caching code a bit.
 276         (ctf_arc_lookup_symbol_name): New, another wrapper.

 280         * testsuite/libctf-lookup/enum-symbol.c (main): Use
 281         ctf_arc_lookup_symbol rather than looking up the name ourselves.
 282         Fish it out repeatedly, to make sure that symbol caching isn't
 283         broken.
 284         (symidx_64): Remove.
 285         (symidx_32): Remove.
 286         * testsuite/libctf-lookup/enum-symbol-obj.lk: Test symbol lookup
 287         in an unlinked object file (indexed symtypetab sections only).
 288         * testsuite/libctf-writable/symtypetab-nonlinker-writeout.c
 289         (try_maybe_reporting): Check symbol types via
 290         ctf_lookup_by_symbol_name as well as ctf_symbol_next.
 291         * testsuite/libctf-lookup/conflicting-type-syms.*: New test of
 292         lookups in a multi-dict archive.
