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.

2016-06-24MIPS objcopy --rename-section fixAlan Modra6-38/+74
Some MIPS targets use a named section symbol rather than a symbol with no name as is used with most ELF targets. When renaming sections, the named section symbol needs to be renamed too. Rather than fix this bug, I'd originally intended to just correct the xfail added recently for update-1.o vs update4.o in update-section.exp, using the same set of targets for the localize-hidden-1 mips xfail. I'd extracted that target test into a new function, is_bad_symtab. It turns out to be useful in readelf.exp too. bfd/ * config.bfd: Delete mips vxworks patterns matched earlier.

2016-05-25Enable 64-bit archives in ar and ranlibH.J. Lu2-0/+8
Since existing ld and gold support the 64-bit (MIPS) ELF archives, we can use the 64-bit (MIPS) ELF archives as 64-bit archives. Since the plugin target is used to create archive in plugin-enabled ar, we need a way to enable 64-bit archives in the plugin target. This patch adds --enable-64-bit-archive to bfd to force 64-bit archives in ar and ranlib. Since both 64-bit MIPS and s390 ELF targets currently use 64-bit archives, 64-bit archives are enabled by default for them. 64-bit archive is generated automatically if the archive is too big. Tested on Linux/x86 and Linux/x86-64 with existing ld and gold. bfd/ PR binutils/14625 * archive.c (bfd_slurp_armap): Replace bfd_elf64_archive_slurp_armap with _bfd_archive_64_bit_slurp_armap.

Mixing MIPS16 and microMIPS code in a single binary isn't usually supported but GAS happily produces such code if requested. However it is not correctly disassembled even if a symbol table is available and function symbols are correctly anotated with the ISA mode. This is because the ELF-header global microMIPS ASE flag takes precedence over MIPS16 function annotation, causing them to be treated as regular MIPS code. Correct the problem by respecting function symbol anotation regardless of the ELF-header flag. binutils/ * testsuite/binutils-all/mips/mixed-mips16-micromips.d: New test. * testsuite/binutils-all/mips/mixed-mips16-micromips.s: New test source. * testsuite/binutils-all/mips/mips.exp: Run the new test. opcodes/ * mips-dis.c (is_compressed_mode_p): Add `micromips_p' operand, replacing references to `micromips_ase' throughout.
