2017-12-19Test binutils_assemble return valueAlan Modra12-290/+323
This is a followup to "binutils nm testsuite tidy". Since the perror in binutils_assemble has been removed, we need to take more care in failure paths. The patch also fixed a number of .exp files that have multiple tests, where an assembly failure returns from the .exp file. In most cases it is nicer to attempt all tests. * testsuite/binutils-all/ar.exp (unique_symbol): Don't run AR if assembly fails. * testsuite/binutils-all/arc/objdump.exp (check_assembly): If objfile is empty, fail test. * testsuite/binutils-all/arm/objdump.exp: Don't return if assembly fails for a test, continue on to other tests. * testsuite/binutils-all/bfin/objdump.exp: Likewise. * testsuite/binutils-all/hppa/objdump.exp: Likewise. * testsuite/binutils-all/m68k/objdump.exp: Likewise. * testsuite/binutils-all/vax/objdump.exp: Likewise. * testsuite/binutils-all/size.exp: Likewise. * testsuite/binutils-all/nm.exp: Likewise.

We can run the gnu_unique_object symbol test on all ELF targets. Those that don't support the symbol type and fail to assemble can just be resolved as "unsupported". This means binutils_assemble can't report an error on assembly failure, but it probably should never have done that anyway. * testsuite/lib/utils-lib.exp (default_binutils_assemble_flags): Don't perror on assembler diagnostic output. * testsuite/binutils-all/nm.exp: Run unique symbol test on all ELF targets.

2017-12-08Fix stripping relocs in a file with mergeable notes.Nick Clifton3-8/+29
A recent Fedora bug (1520805) exposed a problem with objcopy's reloc copying code, when a binary also contains mergeable notes. The note merging code would delete some relocs, but then the reloc copying code would try to put them back again, which did not work. So I am checking in the patch below to fix the problem. The patch also tweaks one of the binutils note merging tests so that it is skipped for the Sparc64 target, since this has funky relocs. binutils * objcopy.c (copy_relocations_in_section): Use the orelocations field of the input section, if it has been initialised. * testsuite/binutils-all/note-2-64.d: Skip test on Sparc64. bfd * elfcode.h (elf_write_relocs): Check for an empty howto field.

2017-11-24elf: Properly compute offsets of note descriptor and next noteH.J. Lu2-2/+13
According to gABI, in a note entry, the note name field, not note name size, is padded for the note descriptor. And the note descriptor field, not note descriptor size, is padded for the next note entry. Also notes are aligned to 4 bytes in 32-bit objects and 8 bytes in 64-bit objects. Since on Linux, .note.ABI-tag and .note.gnu.build-id notes are always aligned to 4 bytes, we need to use alignment of note section or note segment, instead of assuming alignment based on ELF file class.

Symbols like *ABS* defined in bfd/section.c:global_syms are not elf_symbol_type. They can appear on relocs and perhaps other places in an ELF bfd, so a number of places in nm.c and objdump.c are wrong to cast an asymbol based on the bfd being ELF.

2017-11-17Fix a snafu in a previous update to readelf that stopped it from printing ↵Nick Clifton2-0/+6
archive member names along with the archive file name. -- This patch causes problems for glibc linknamespace tests because of how it changes the output format of readelf on .a files. Previously, "readelf -W -s libc.a" would produce output starting e.g.: File: /scratch/jmyers/glibc/many8/build/glibcs/x86_64-linux-gnu/glibc/libc.a(init-first.o) Symbol table '.symtab' contains 30 entries: and continuing with symbol information for each object in that .a file. After this commit, instead it starts: File: /scratch/jmyers/glibc/many8/build/glibcs/x86_64-linux-gnu/glibc/libc.a Symbol table '.symtab' contains 30 entries: and every object's symbol information starts with the same File: line, missing any information about which object's symbols (within libc.a) are being listed. I think the previous File: lines that said libc.a(init-first.o) etc., identifying the particular object within libc.a, were clearly preferable, and the glibc linknamespace tests rely on having that information about the individual object within libc.a. -- binutils * readelf.c (process_archive): Include member name in the file_name of the filedata structure.

2017-11-15Add support to readelf and objdump for following links to separate debug ↵Nick Clifton19-1482/+2640
information files. Hi Guys, I am applying the rather large patch attached to this email to enhance the readelf and objdump programs so that they now have the ability to follow links to separate debug info files. (As requested by PR 15152). So for example whereas before we had this output: $ readelf -wi main.exe Contents of the .debug_info section: [...] <15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c) [...] With the new option enabled we get: $ readelf -wiK main.exe main.exe: Found separate debug info file: dwz.debug Contents of the .debug_info section (loaded from main.exe): [...] <15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c) /home/nickc/Downloads/dwzm [...] The link following feature also means that we can get two lots of output if the same section exists in both the main file and the separate debug info file: $ readelf -wiK main.exe main.exe: Found separate debug info file: dwz.debug Contents of the .debug_info section (loaded from main.exe): [...] Contents of the .debug_info section (loaded from dwz.debug): [...] The patch also adds the ability to display the contents of debuglink sections: $ readelf -wk main.exe Contents of the .gnu_debugaltlink section: Separate debug info file: dwz.debug Build-ID (0x14 bytes): c4 a8 89 8d 64 cf 70 8a 35 68 21 f2 ed 24 45 3e 18 7a 7a 93 Naturally there are long versions of these options (=follow-links and =links). The documentation has been updated as well, and since both readelf and objdump use the same set of debug display options, I have moved the text into a separate file. There are also a couple of new binutils tests to exercise the new behaviour. There are a couple of missing features in the current patch however, although I do intend to address them in follow up submissions: Firstly the code does not check the build-id inside separate debug info files when it is searching for a file specified by a .gnu_debugaltlink section. It just assumes that if the file is there, then it contains the information being sought. Secondly I have not checked the DWARF-5 version of these link features, so there will probably be code to add there. Thirdly I have only implemented link following for the DW_FORM_GNU_strp_alt format. Other alternate formats (eg DW_FORM_GNU_ref_alt) have yet to be implemented. Lastly, whilst implementing this feature I found it necessary to move some of the global variables used by readelf (eg section_headers) into a structure that can be passed around. I have moved all of the global variables that were necessary to get the patch working, but I need to complete the operation and move the remaining, file-specific variables (eg dynamic_strings).

This patch is a first pass at fixing readelf message pluralization. I've deliberately not fixed the "out of memory" errors since it's very unlikely that they will ever be complaining about not being able to allocate for a single entry, and a few others where the size is very unlikely to be 1 byte. Then there are messages like this one: "Out of %lu items there are %zu bucket clashes (longest of %zu entries).\n" I suppose this could be split into three parts, "Of %lu items ", "there are %zu bucket clashes ", and "(longest of %zu entries).\n", each part being printed separately, but that might not be ideal for sentence construction in other languages.

2017-11-07ngettext supportAlan Modra2-2/+13
binutils has lacked proper pluralization of output messages for a long time, for example, readelf will display information about a section that "contains 1 entries" or "There are 1 section headers". Fixing this properly requires us to use ngettext, because other languages have different rules to English. This patch defines macros for ngettext and friends to handle builds with --disable-nls, and tidies the existing nls support. I've redefined gettext rather than just defining "_" as dgettext in bfd and opcodes in case someone wants to use gettext there (which might conceivably happen with generated code). bfd/ * sysdep.h: Formatting, comment fixes. (gettext, ngettext): Redefine when ENABLE_NLS. (ngettext, dngettext, dcngettext): Define when !ENABLE_NLS. (_): Define using gettext.

2017-10-27dwarf: Read register number as unsigned in DW_CFA_def_cfa*Simon Marchi2-4/+10
When displaying the .debug_frame section, the register numbers in the DW_CFA_def_cfa* statements are read as signed numbers. I have come across a target that has register 121, encoded as 0x79 in unsigned LEB128. Interpreting this as signed results in -7, which makes readelf display "r-7". The DWARF5 standard (6.4.2.2) states that the register numbers should be treated as unsigned LEB128. Simply replacing READ_SLEB with READ_ULEB resulted in warnings like these: /home/emaisin/src/binutils-gdb/binutils/dwarf.c: In function ‘display_debug_frames’: /home/emaisin/src/binutils-gdb/binutils/dwarf.c:355:17: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare] if ((var) != _val) \ ^ /home/emaisin/src/binutils-gdb/binutils/dwarf.c:7866:8: note: in expansion of macro ‘READ_ULEB’ READ_ULEB (fc->cfa_reg); ^ ... so I also changed Frame_Chunk::cfa_reg to an unsigned int. binutils/ChangeLog: * dwarf.c (struct Frame_Chunk) <cfa_reg>: Change type to unsigned int.
