libctf/ChangeLog

   1 2021-02-17  Nick Alcock  <nick.alcock@oracle.com>
   2
   3         * ctf-impl.h (ctf_dict_t) <ctf_symhash>: New.
   4         <ctf_symhash_latest>: Likewise.
   5         (struct ctf_archive_internal) <ctfi_crossdict_cache>: New.
   6         <ctfi_symnamedicts>: New.
   7         <ctfi_syms>: Remove.
   8         (ctf_lookup_symbol_name): Remove.
   9         * ctf-lookup.c (ctf_lookup_symbol_name): Propagate errors from
  10         parent properly.  Make static.
  11         (ctf_lookup_symbol_idx): New, linear search for the symbol name,
  12         cached in the crossdict cache's ctf_symhash (if available), or
  13         this dict's (otherwise).
  14         (ctf_try_lookup_indexed): Allow the symname to be passed in.
  15         (ctf_lookup_by_symbol): Turn into a wrapper around...
  16         (ctf_lookup_by_sym_or_name): ... this, supporting name lookup too,
  17         using ctf_lookup_symbol_idx in non-writable dicts.  Special-case
  18         name lookup in dynamic dicts without reported symbols, which have
  19         no symtab or dynsymidx but where name lookup should still work.
  20         (ctf_lookup_by_symbol_name): New, another wrapper.
  21         * ctf-archive.c (enosym): Note that this is present in
  22         ctfi_symnamedicts too.
  23         (ctf_arc_close): Adjust for removal of ctfi_syms.  Free the
  24         ctfi_symnamedicts.
  25         (ctf_arc_flush_caches): Likewise.
  26         (ctf_dict_open_cached): Memoize the first cached dict in the
  27         crossdict cache.
  28         (ctf_arc_lookup_symbol): Turn into a wrapper around...
  29         (ctf_arc_lookup_sym_or_name): ... this.  No longer cache
  30         ctf_id_t lookups: just call ctf_lookup_by_symbol as needed (but
  31         still cache the dicts those lookups succeed in).  Add
  32         lookup-by-name support, with dicts of successful lookups cached in
  33         ctfi_symnamedicts.  Refactor the caching code a bit.
  34         (ctf_arc_lookup_symbol_name): New, another wrapper.
  35         * ctf-open.c (ctf_dict_close): Free the ctf_symhash.
  36         * libctf.ver (LIBCTF_1.2): New version.  Add
  37         ctf_lookup_by_symbol_name, ctf_arc_lookup_symbol_name.
  38         * testsuite/libctf-lookup/enum-symbol.c (main): Use
  39         ctf_arc_lookup_symbol rather than looking up the name ourselves.
  40         Fish it out repeatedly, to make sure that symbol caching isn't
  41         broken.
  42         (symidx_64): Remove.
  43         (symidx_32): Remove.
  44         * testsuite/libctf-lookup/enum-symbol-obj.lk: Test symbol lookup
  45         in an unlinked object file (indexed symtypetab sections only).
  46         * testsuite/libctf-writable/symtypetab-nonlinker-writeout.c
  47         (try_maybe_reporting): Check symbol types via
  48         ctf_lookup_by_symbol_name as well as ctf_symbol_next.
  49         * testsuite/libctf-lookup/conflicting-type-syms.*: New test of
  50         lookups in a multi-dict archive.
  51

 124         were reported and force-indexing is off (i.e., we are doing a
 125         final link).
 126         (ctf_serialize): Handle the !LCTF_LINKING case by writing out an
 127         indexed, sorted symtypetab (and allow SYMFP to be NULL in this
 128         case).  Turn sorting off if this is a non-final link.  Only delete
 129         nonstatic vars if we are filtering symbols and the linker has
 130         reported some.
 131         * testsuite/libctf-regression/nonstatic-var-section-ld-r*:
 132         New test of variable and symtypetab section population when

 135         Likewise, when ld of an executable is used.
 136         * testsuite/libctf-regression/nonstatic-var-section-ld.lk:
 137         Likewise, when ld -shared alone is used.
 138         * testsuite/libctf-regression/nonstatic-var-section-ld*.c:
 139         Lookup programs for the above.
 140         * testsuite/libctf-writable/symtypetab-nonlinker-writeout.*: New
 141         test, testing survival of symbols across ctf_write paths.
 142         * testsuite/lib/ctf-lib.exp (run_lookup_test): New option,
 143         nonshared, suppressing linking of the SOURCE with -shared.

 154         base type if looking up a nonexistent pointer type.
