  46 2021-02-20  Nick Alcock  <nick.alcock@oracle.com>
  47
  48         * ctf-impl.h (ctf_dict_t) <ctf_symhash>: New.
  49         <ctf_symhash_latest>: Likewise.
  50         (struct ctf_archive_internal) <ctfi_crossdict_cache>: New.
  51         <ctfi_symnamedicts>: New.
  52         <ctfi_syms>: Remove.
  53         (ctf_lookup_symbol_name): Remove.
  54         * ctf-lookup.c (ctf_lookup_symbol_name): Propagate errors from
  55         parent properly.  Make static.
  56         (ctf_lookup_symbol_idx): New, linear search for the symbol name,
  57         cached in the crossdict cache's ctf_symhash (if available), or
  58         this dict's (otherwise).
  59         (ctf_try_lookup_indexed): Allow the symname to be passed in.
  60         (ctf_lookup_by_symbol): Turn into a wrapper around...
  61         (ctf_lookup_by_sym_or_name): ... this, supporting name lookup too,
  62         using ctf_lookup_symbol_idx in non-writable dicts.  Special-case
  63         name lookup in dynamic dicts without reported symbols, which have
  64         no symtab or dynsymidx but where name lookup should still work.
  65         (ctf_lookup_by_symbol_name): New, another wrapper.
  66         * ctf-archive.c (enosym): Note that this is present in
  67         ctfi_symnamedicts too.
  68         (ctf_arc_close): Adjust for removal of ctfi_syms.  Free the
  69         ctfi_symnamedicts.

  71         (ctf_dict_open_cached): Memoize the first cached dict in the
  72         crossdict cache.
  73         (ctf_arc_lookup_symbol): Turn into a wrapper around...
  74         (ctf_arc_lookup_sym_or_name): ... this.  No longer cache
  75         ctf_id_t lookups: just call ctf_lookup_by_symbol as needed (but
  76         still cache the dicts those lookups succeed in).  Add
  77         lookup-by-name support, with dicts of successful lookups cached in
  78         ctfi_symnamedicts.  Refactor the caching code a bit.
  79         (ctf_arc_lookup_symbol_name): New, another wrapper.
  80         * ctf-open.c (ctf_dict_close): Free the ctf_symhash.
  81         * libctf.ver (LIBCTF_1.2): New version.  Add
  82         ctf_lookup_by_symbol_name, ctf_arc_lookup_symbol_name.
  83         * testsuite/libctf-lookup/enum-symbol.c (main): Use
  84         ctf_arc_lookup_symbol rather than looking up the name ourselves.
  85         Fish it out repeatedly, to make sure that symbol caching isn't
  86         broken.
  87         (symidx_64): Remove.
  88         (symidx_32): Remove.
  89         * testsuite/libctf-lookup/enum-symbol-obj.lk: Test symbol lookup
  90         in an unlinked object file (indexed symtypetab sections only).
  91         * testsuite/libctf-writable/symtypetab-nonlinker-writeout.c
  92         (try_maybe_reporting): Check symbol types via
  93         ctf_lookup_by_symbol_name as well as ctf_symbol_next.
  94         * testsuite/libctf-lookup/conflicting-type-syms.*: New test of
  95         lookups in a multi-dict archive.
  96

 109
 110 2021-02-03  Nick Alcock  <nick.alcock@oracle.com>

 113         (TCL_TRY): ... this, if Tcl supports try/catch.
 114         * Makefile.am (TCL_TRY): Run the testsuite only if set.

 169         were reported and force-indexing is off (i.e., we are doing a
 170         final link).
 171         (ctf_serialize): Handle the !LCTF_LINKING case by writing out an
 172         indexed, sorted symtypetab (and allow SYMFP to be NULL in this
 173         case).  Turn sorting off if this is a non-final link.  Only delete
 174         nonstatic vars if we are filtering symbols and the linker has
 175         reported some.
 176         * testsuite/libctf-regression/nonstatic-var-section-ld-r*:
 177         New test of variable and symtypetab section population when
 178         ld -r is used.

 180         Likewise, when ld of an executable is used.

 182         Likewise, when ld -shared alone is used.
 183         * testsuite/libctf-regression/nonstatic-var-section-ld*.c:
 184         Lookup programs for the above.
 185         * testsuite/libctf-writable/symtypetab-nonlinker-writeout.*: New
 186         test, testing survival of symbols across ctf_write paths.
 187         * testsuite/lib/ctf-lib.exp (run_lookup_test): New option,
 188         nonshared, suppressing linking of the SOURCE with -shared.

 338         * configure.ac (BFD_LIBADD): Remove.
 339         (BFD_DEPENDENCIES): Likewise. Remove associated cases.
 340         (SHARED_LIBADD): Rename to...
 341         (CTF_LIBADD): ... this.  Stick in a suitable libiberty even when
 342         linking statically.
 343         * Makefile.am (libctf_nobfd_la_LIBADD): Adjust accordingly.
 344         libctf uses libintl.
 345         (libctf_la_LIBADD): Reference libbfd.la directly, not via
 346         BFD_LIBADD.
 347         (libctf_la_DEPENDENCIES): Remove.
 348         * Makefile.in: Regenerate.

 360         type-printing parts of this into...
 361         (ctf_dump_format_type): ... here, to be shared by all type printers.
 362         Get the errno value for non-representable types right.  Do not print
 363         bitfield info for non-bitfields.  Improve the format and indentation
 364         of other type output.  Shuffle spacing around to make all indentation
 365         either 'width of column' or 4 chars.
 366         (ctf_dump_label): Pass CTF_FT_REFS to ctf_dump_format_type.
 367         (ctf_dump_objts): Likewise.  Spacing shuffle.
 368         (ctf_dump_var): Likewise.
 369         (type_hex_digits): Migrate down in the file, to above its new user.
 370         (ctf_dump_type): Indent here instead.  Pass CTF_FT_REFS to
 371         ctf_dump_format_type. Don't trim off excess linefeeds now we no
 372         longer generate them.  Dump enumerated types.

 379         (ctf_type_align): Likewise.
 380         * ctf-create.c (ctf_add_member_offset): Yield ECTF_INCOMPLETE
 381         when adding a member without explicit offset when this member, or
 382         the previous member, is incomplete.
 383         * ctf-dump.c (ctf_dump_format_type): Do not try to print the size of
 384         forwards.
 385         (ctf_dump_member): Do not try to print their alignment.

 390         (ctf_dump_format_type): Don't emit the size for function objects.
 391         Dump the element type of arrays like we dump the pointed-to type of
 392         pointers, etc.

 398         (ctf_dump_str): Add 0x to the hex string offsets.
 399         (ctf_dump_membstate_t) <cdm_toplevel_indent>: New.
 400         (ctf_dump_type): Adjust.  Free it when we're done.
 401         (type_hex_digits): New.
 402         (ctf_dump_member): Align output depending on the width of the type
 403         ID being generated.  Use printf padding, not a loop, to generate
 404         indentation.
