   2
   3         * configure.ac: Invoke AC_CANONICAL_TARGET, AC_CANONICAL_HOST

   9
  10         * ctf-impl.h (ctf_dict_t) <ctf_symhash>: New.
  11         <ctf_symhash_latest>: Likewise.
  12         (struct ctf_archive_internal) <ctfi_crossdict_cache>: New.
  13         <ctfi_symnamedicts>: New.
  14         <ctfi_syms>: Remove.
  15         (ctf_lookup_symbol_name): Remove.
  16         * ctf-lookup.c (ctf_lookup_symbol_name): Propagate errors from
  17         parent properly.  Make static.
  18         (ctf_lookup_symbol_idx): New, linear search for the symbol name,
  19         cached in the crossdict cache's ctf_symhash (if available), or
  20         this dict's (otherwise).
  21         (ctf_try_lookup_indexed): Allow the symname to be passed in.
  22         (ctf_lookup_by_symbol): Turn into a wrapper around...
  23         (ctf_lookup_by_sym_or_name): ... this, supporting name lookup too,
  24         using ctf_lookup_symbol_idx in non-writable dicts.  Special-case
  25         name lookup in dynamic dicts without reported symbols, which have
  26         no symtab or dynsymidx but where name lookup should still work.
  27         (ctf_lookup_by_symbol_name): New, another wrapper.
  28         * ctf-archive.c (enosym): Note that this is present in
  29         ctfi_symnamedicts too.
  30         (ctf_arc_close): Adjust for removal of ctfi_syms.  Free the
  31         ctfi_symnamedicts.
  32         (ctf_arc_flush_caches): Likewise.
  33         (ctf_dict_open_cached): Memoize the first cached dict in the
  34         crossdict cache.
  35         (ctf_arc_lookup_symbol): Turn into a wrapper around...
  36         (ctf_arc_lookup_sym_or_name): ... this.  No longer cache
  37         ctf_id_t lookups: just call ctf_lookup_by_symbol as needed (but
  38         still cache the dicts those lookups succeed in).  Add
  39         lookup-by-name support, with dicts of successful lookups cached in
  40         ctfi_symnamedicts.  Refactor the caching code a bit.
  41         (ctf_arc_lookup_symbol_name): New, another wrapper.
  42         * ctf-open.c (ctf_dict_close): Free the ctf_symhash.
  43         * libctf.ver (LIBCTF_1.2): New version.  Add
  44         ctf_lookup_by_symbol_name, ctf_arc_lookup_symbol_name.
  45         * testsuite/libctf-lookup/enum-symbol.c (main): Use
  46         ctf_arc_lookup_symbol rather than looking up the name ourselves.
  47         Fish it out repeatedly, to make sure that symbol caching isn't
  48         broken.
  49         (symidx_64): Remove.
  50         (symidx_32): Remove.
  51         * testsuite/libctf-lookup/enum-symbol-obj.lk: Test symbol lookup
  52         in an unlinked object file (indexed symtypetab sections only).
  53         * testsuite/libctf-writable/symtypetab-nonlinker-writeout.c
  54         (try_maybe_reporting): Check symbol types via
  55         ctf_lookup_by_symbol_name as well as ctf_symbol_next.
  56         * testsuite/libctf-lookup/conflicting-type-syms.*: New test of
  57         lookups in a multi-dict archive.

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

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

 149         * testsuite/lib/ctf-lib.exp (run_lookup_test): New option,
 150         nonshared, suppressing linking of the SOURCE with -shared.

 331         (type_hex_digits): Migrate down in the file, to above its new user.
 332         (ctf_dump_type): Indent here instead.  Pass CTF_FT_REFS to
 333         ctf_dump_format_type. Don't trim off excess linefeeds now we no
 334         longer generate them.  Dump enumerated types.
