* Add dwarf_endianity_string and dwarf_decimal_sign_string.upstream/mjw/dwarfstringsMark Wielaard2012-08-166-1/+127
| | | | | | | dwarf_endianity_string for DW_END codes used with DW_AT_endianity. dwarf_decimal_sign_string for DW_DS codes used with DW_AT_decimal_sign. Signed-off-by: Mark Wielaard <[email protected]>
* libdw: Add dwarfstrings functions.Mark Wielaard2012-08-1620-2/+964
| | | | | | | | | | | | | | Introduce dwarf_access_string, dwarf_attr_string, dwarf_calling_convention_string, dwarf_discr_list_string, dwarf_encoding_string, dwarf_form_string, dwarf_identifier_case_string, dwarf_inline_string, dwarf_lang_string, dwarf_line_extended_opcode_string, dwarf_line_standard_opcode_string, dwarf_locexpr_opcode_string, dwarf_ordering_string, dwarf_tag_string, dwarf_virtuality_string, dwarf_visibility_string from dwarf branch. Remove similar functions from readelf and tests. Signed-off-by: Mark Wielaard <[email protected]>
* Rewrite DWARF string functions using known-dwarf macros.Mark Wielaard2012-08-163-4/+10
| | | | | | | | readelf and tests were using hard coded string tables to produce DWARF string constants. Use the known-dwarf macros to redefine these and reduce code. Technique comes from dwarf branch dwarfstrings.c. Signed-off-by: Mark Wielaard <[email protected]>
* libdw: Add support for DWZ multifile forms DW_FORM_GNU_ref_alt/strp_alt.Mark Wielaard2012-08-0913-12/+210
| | | | | | | | | | | | | | | DWZ multifile forms http://www.dwarfstd.org/ShowIssue.php?issue=120604.1 DW_FORM_GNU_ref_alt and DW_FORM_GNU_strp_alt reference an alternative debuginfo file. dwarf_begin and dwarf_begin_elf will try to use this automatically. There are no user visible changes to the libdw interface. dwarf_formref_die, dwarf_formstring and dwarf_formudata can now return a Dwarf_Die which comes from a CU in the alternative Dwarf descriptor. __libdw_read_offset was adjusted to take an alternative Dwarf descriptor into account.

* Add DW_OP_GNU_parameter_ref to dwarf.h and handle it in readelf.Mark Wielaard2012-07-262-0/+5
| | | | | | | DW_OP_GNU_parameter_ref takes as operand a 4 byte CU relative reference to the abstract optimized away DW_TAG_formal_parameter. Signed-off-by: Mark Wielaard <[email protected]>

* Fix bug using dwarf_next_unit to iterate over .debug_typesTom Tromey2012-03-212-35/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | * libdw_findcu.c (findcu_cb): Move earlier. (__libdw_intern_next_unit): Add new CU to search tree here... (__libdw_findcu): ... not here. * typeiter.c: New file. * run-typeiter.sh: New file. * testfile59.bz2: New file. * Makefile.am (noinst_PROGRAMS): Add typeiter. (TESTS): Add run-typeiter.sh. (EXTRA_DIST): Add run-typeiter.sh, testfile59.bz2. (typeiter_LDADD): New variable. If you call dwarf_next_unit to iterate over .debug_types, then call dwarf_offdie_types, you can see a failure if some earlier call happened to call __libdw_intern_next_unit via dwarf_formref_die. What happens is that __libdw_intern_next_unit updates the Dwarf's next_tu_offset, but does not add the TU to the TU search tree. So, the call to dwarf_offdie_types does not find the TU in the tree, and will not search any more, causing a failure. This fix changes __libdw_intern_next_unit to add the TU to the search tree, rather than relying on __libdw_findcu to do it.
