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

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

 231         (ctf_serialize): Handle the !LCTF_LINKING case by writing out an
 232         indexed, sorted symtypetab (and allow SYMFP to be NULL in this
 233         case).  Turn sorting off if this is a non-final link.  Only delete
 234         nonstatic vars if we are filtering symbols and the linker has
 235         reported some.
 236         * testsuite/libctf-regression/nonstatic-var-section-ld-r*:
 237         New test of variable and symtypetab section population when

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