2016-11-04set default-directory in dwarf-browseTom Tromey2-1/+7
I've been using dwarf-mode.el again recently and I found it mildly annoying that the mode doesn't set default-directory. Setting it means that operations in the dwarf-browsing buffer default to the directory holding the object file being investigated. This bumps the version number as well so that updating it via the package manager works properly. 2016-11-04 Tom Tromey <tom@tromey.com> * dwarf-mode.el (dwarf-browse): Set default-directory. Bump version number.

2016-09-29Frame info dump: Fix bad register marks.Andreas Krebbel1-10/+23
On S/390 we see quite often registers marked as "bad register" in the readelf --debug-dump=frames or objdump -Wf output. 00000000 0000000000000014 00000000 CIE Version: 1 Augmentation: "zR" Code alignment factor: 1 Data alignment factor: -8 Return address column: 14 Augmentation data: 1b DW_CFA_def_cfa: r15 ofs 160 DW_CFA_nop DW_CFA_nop DW_CFA_nop ... 00000050 000000000000001c 00000054 FDE cie=00000000 pc=0000000080000e58..0000000080000e84 DW_CFA_advance_loc: 6 to 0000000080000e5e DW_CFA_offset: r14 at cfa-48 DW_CFA_offset: r15 at cfa-40 DW_CFA_advance_loc: 6 to 0000000080000e64 DW_CFA_def_cfa_offset: 320 DW_CFA_advance_loc: 18 to 0000000080000e76 DW_CFA_restore: bad register: r15 <------ DW_CFA_restore: r14 DW_CFA_def_cfa_offset: 160 This is triggered by this check in display_debug_frames (dwarf.c): case DW_CFA_restore: if (opa >= (unsigned int) cie->ncols || opa >= (unsigned int) fc->ncols) reg_prefix = bad_reg; cie->ncols is number of registers referenced in the CIE which is 15 due to r14 being given as return address column. So for the CFA_restore of r15 a "bad register" is being printed while the same rule on r14 is ok. The reason for this check is to prevent wild memory accesses when reading input with corrupted register values while accessing the col_type/col_offset arrays. However in that case r15 is a perfectly valid register. It just happens not to be mentioned in the CIE. Hence restoring the CIE rule for r15 should end up with the default rule which is DW_CFA_undefined. This probably wasn't observed on other platforms because they either do not use CFA_restore (x86-64) or do not issue CFA_restore on registers with a higher number than the return address column. binutils/ChangeLog: 2016-09-29 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * dwarf.c (frame_display_row): Fix formatting of return address register column.

This patch extends Tag_GNU_Power_ABI_FP to cover long double ABIs, makes the assembler warn about undefined tag values, and removes similar warnings from the linker.

2016-07-14objcopy/strip: Add option --remove-relocations=SECTIONPATTERNAndrew Burgess12-5/+242
The objcopy and strip tools make use of the bfd library to manipulate the state of the input file (to produce an output file). Within the input file (for ELF at least), relocations are held within a section, and so, if the user wanted to remove the relocations, but keep the section to which the relocations would have been applied, it is tempting to think that specifying the name of a relocation section to objcopy's --remove-section option might do what you want, for example: objcopy --remove-section=.rela.text input.elf output.elf However, this does not work. The reason is that when the input file is loaded, relocations are not managed as sections, but are, instead, loaded as data associated with the section to which the relocations would be applied. In our example above the relocations in '.rela.text' are held as data on the section '.text' once 'input.elf' is loaded. One task that objcopy and strip do is copy the relocations from the input file to the output file if the section is also being copied from the input file to the output file. This commit adds a new command line option for objcopy and strip, --remove-relocations, which can be used to remove the relocations, while keeping the section that the relocations would have been applied to, for example: objcopy --remove-relocations=.text input.elf output.elf in this case the section '.text' will appear in both 'input.elf' and 'output.elf', but any relocations in 'input.elf' that apply to '.text' will not be present in 'output.elf'. I have also added a special case to the handling of --remove-section that spots if a user tries to remove a relocation section (currently this is done by spotting the '.rela.' or '.rel.' prefix) and forwards the request to --remove-relocations. As with --remove-section and --only-section the --remove-relocations option supports the '!' prefix on the section-patterns it takes to allow for sections to be specifically not matched. There are tests for all the new functionality. binutils/ChangeLog: * doc/binutils.texi (objcopy): Document 'remove-relocations'. (strip): Likewise. * objcopy.c (SECTION_CONTEXT_REMOVE_RELOCS): Define. (enum command_line_switch): Add 'OPTION_REMOVE_RELOCS'. (struct option strip_options): Add 'remove-relocations'.

2016-07-14objcopy/strip: Allow section patterns starting with '!'.Andrew Burgess8-11/+124
For symbol matching, prefixing a pattern with '!' will indicate a non-matching pattern, however, this is not the case for section patterns. As a result it is not possible to say "apply this action to all sections except ...". With this commit the objcopy and strip tools now support '!' prefix for section patterns, so we can say: objcopy --remove-section="*" --remove-section="!.text*" Which will remove all sections, except those matching the pattern '.text*'. binutils/ChangeLog: * objcopy.c (find_section_list): Handle section patterns starting with '!' being a non-matching pattern. * doc/binutils.texi (objcopy): Give example of using '!' with --remove-section and --only-section.
