 105         <ctf_symhash_latest>: Likewise.
 106         (struct ctf_archive_internal) <ctfi_crossdict_cache>: New.

 109         (ctf_lookup_symbol_name): Remove.
 110         * ctf-lookup.c (ctf_lookup_symbol_name): Propagate errors from
 111         parent properly.  Make static.
 112         (ctf_lookup_symbol_idx): New, linear search for the symbol name,
 113         cached in the crossdict cache's ctf_symhash (if available), or
 114         this dict's (otherwise).
 115         (ctf_try_lookup_indexed): Allow the symname to be passed in.
 116         (ctf_lookup_by_symbol): Turn into a wrapper around...
 117         (ctf_lookup_by_sym_or_name): ... this, supporting name lookup too,
 118         using ctf_lookup_symbol_idx in non-writable dicts.  Special-case
 119         name lookup in dynamic dicts without reported symbols, which have
 120         no symtab or dynsymidx but where name lookup should still work.
 121         (ctf_lookup_by_symbol_name): New, another wrapper.
 122         * ctf-archive.c (enosym): Note that this is present in

 128         crossdict cache.
 129         (ctf_arc_lookup_symbol): Turn into a wrapper around...
 130         (ctf_arc_lookup_sym_or_name): ... this.  No longer cache
 131         ctf_id_t lookups: just call ctf_lookup_by_symbol as needed (but
 132         still cache the dicts those lookups succeed in).  Add
 133         lookup-by-name support, with dicts of successful lookups cached in
 134         ctfi_symnamedicts.  Refactor the caching code a bit.
 135         (ctf_arc_lookup_symbol_name): New, another wrapper.
 136         * ctf-open.c (ctf_dict_close): Free the ctf_symhash.
 137         * libctf.ver (LIBCTF_1.2): New version.  Add
 138         ctf_lookup_by_symbol_name, ctf_arc_lookup_symbol_name.
 139         * testsuite/libctf-lookup/enum-symbol.c (main): Use
 140         ctf_arc_lookup_symbol rather than looking up the name ourselves.
 141         Fish it out repeatedly, to make sure that symbol caching isn't
 142         broken.
 143         (symidx_64): Remove.
 144         (symidx_32): Remove.
 145         * testsuite/libctf-lookup/enum-symbol-obj.lk: Test symbol lookup
 146         in an unlinked object file (indexed symtypetab sections only).
 147         * testsuite/libctf-writable/symtypetab-nonlinker-writeout.c
 148         (try_maybe_reporting): Check symbol types via
 149         ctf_lookup_by_symbol_name as well as ctf_symbol_next.
 150         * testsuite/libctf-lookup/conflicting-type-syms.*: New test of
 151         lookups in a multi-dict archive.

 224         (symtypetab_density): Adjust nonnullity.  Exit early if no symbols
 225         were reported and force-indexing is off (i.e., we are doing a
 226         final link).
 227         (ctf_serialize): Handle the !LCTF_LINKING case by writing out an
 228         indexed, sorted symtypetab (and allow SYMFP to be NULL in this
 229         case).  Turn sorting off if this is a non-final link.  Only delete
 230         nonstatic vars if we are filtering symbols and the linker has
 231         reported some.
 232         * testsuite/libctf-regression/nonstatic-var-section-ld-r*:
 233         New test of variable and symtypetab section population when

 239         * testsuite/libctf-regression/nonstatic-var-section-ld*.c:
 240         Lookup programs for the above.

 242         test, testing survival of symbols across ctf_write paths.
 243         * testsuite/lib/ctf-lib.exp (run_lookup_test): New option,
 244         nonshared, suppressing linking of the SOURCE with -shared.
