* readelf: print actual DW_OP_GNU_parameter_ref DIE offset.Mark Wielaard2013-07-132-32/+66
| | | | | | | | | | | DW_OP_GNU_parameter_ref takes as argument a CU relative offset to a DW_TAG_formal_parameter DIE. Printing just that relative offset makes it hard to find the actual DIE in the output. Now print the actual DIE offset instead (unless -U is given). We already passed around the base address of the CU. Now we pass around the actual CU so we can use it to find both the base address and the CU offset.

* readelf: Format first DW_OP_GNU_implicit_pointer argument as DIE offset.Mark Wielaard2013-05-062-1/+6
| | | | | | | | | | | | | | | | | | | Make the printing of DW_OP_GNU_implicit_pointer consistent with other operations that have a DIE offset as argument. Before: [ 6e4a] formal_parameter abstract_origin (ref4) [ 616a] location (exprloc) [ 0] GNU_implicit_pointer 0x6dbe, +0 After: [ 6e4a] formal_parameter abstract_origin (ref4) [ 616a] location (exprloc) [ 0] GNU_implicit_pointer [ 6dbe] +0 Signed-off-by: Mark Wielaard <[email protected]>
* Updates for Automake 1.13.Mark Wielaard2013-04-262-1/+5
| | | | | | | autoreconf will install config/test-driver, ignore it. Update gettext m4 and po files to version 0.18.2. Use AM_CPPFLAGS instead of INCLUDES. All changes are backward compatible with Automake 1.11.

| | | | | | | Version 8 just indicates that if the .gdb_index was generated by the gold linker it correctly includes TUs for symbols. http://sourceware.org/PR15021 Signed-off-by: Mark Wielaard <[email protected]>
* Fix two memory leaks in findtextrel and strip.Mark Wielaard2013-03-013-2/+14
| | | | | | | | | | | The findtextrel leak is real, when processing lots of files without text relocations the files and memory wouldn't be released. The strip leak is minor since it can only happen when using -f which only allows one file as argument. But it is nice to see valgrind say: "All heap blocks were freed -- no leaks are possible".

* elflint.c (check_symtab): Add __bss_start__ to the list of allowed symbols.Mark Wielaard2013-02-242-0/+6

* elflint: Add two more symbols to gnuld list of allowed bad values.Mark Wielaard2013-02-062-3/+17
| | | | | | | | | | | | | Add __bss_start and __TMC_END__ to the list of symbols allowed to have out of section values because of the following GNU ld bug: http://sourceware.org/bugzilla/show_bug.cgi?id=13621. Allow them to appear in either .symtab or .dynsym, but only when they are zero sized. It is impossible to define a general rule for this bug, but this should catch most common issues that are mostly harmless because the symbols signify the removed section was empty to being with. This catches at least all symbols often flagged in the tests. Signed-off-by: Mark Wielaard <[email protected]>

* readelf: Add --elf-section input option to inspect an embedded ELF file.Mark Wielaard2013-01-162-0/+159
| | | | | | | | | | | | | | | | | | Some binaries might have (compressed) embedded ELF files inside a section. The default section name for this is .gnu_debugdata. This normally consists of just those sections needed to provide an auxiluary symbol table. But can theoretically contain other (debug) sections. The new --elf-section arguments makes it possible to easily inspect it as if it is a normal ELF file. libdwfl takes care of automatically decompressing any data in the section if necessary. https://fedoraproject.org/wiki/Features/MiniDebugInfo ELF input selection: --elf-section[=SECTION] Use the named SECTION (default .gnu_debugdata) as (compressed) ELF input data Signed-off-by: Mark Wielaard <[email protected]>

| | | | | | | | | The FDE initial_location is printed as start address with format_dwarf_addr. Which does the right thing for .debug_frame addresses, but in .eh_frame this is encoded as DW_EH_PE_pcrel and so needs to be adjusted before formatting. Signed-off-by: Mark Wielaard <[email protected]>

* In mixed core notes, don't let handle_core_item repeat.Petr Machata2012-09-251-1/+5
| | | | | | | | | | | | If a core note contains both registers and items, descsz is 0 to express that we don't wish to repeat the items. If there is only one item in such note, a special block of code hits that passes &size to handle_core_item, which will decrease that size by the amount consumed by the item. But because size is 0, it underflows and wraps, and the loop following this block, which handles the common case, overruns the core note buffer. Signed-off-by: Petr Machata <[email protected]>

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.
