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. Combine mips*-*-none with mips*-*-elf*. binutils/ * objcopy.c (find_section_rename): Forward declare. Remove ibfd and sec_ptr param. Add old_name param. Allow for NULL returned_flags.

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.

2016-05-18MIPS/opcodes: Correct mixed MIPS16 and microMIPS disassemblyMaciej W. Rozycki4-0/+70
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.

2016-03-21arc: Add nps400 machine type, and assembler flag.Andrew Burgess2-0/+7
This commit introduces the nps400 machine type as a variant of arc. There's a new flag in the assembler to select this machine type. All other changes are just adding handling of the new machine type into the relevant places. The nps400 is an arc700 variant with some vendor specific instructions added into the instruction set. This commit does not add any of the new instructions, this is just laying the groundwork for future commits. However, in preparation for these new instructions a new opcode define for nps400 has been added to include/opcode/arc.h, this new opcode define is used in the assembler and disassembler along with the existing define for arc700 such that when assembling and disassembling for nps400 the user will have access to all arc700 instructions and all the nps400 vendor extension instructions. bfd/ChangeLog: * archures.c (bfd_mach_arc_nps400): Define. * bfd-in2.h: Regenerate. * cpu-arc.c (arch_info_struct): New entry for nps400, renumber some existing entries to make space. * elf32-arc.c (arc_elf_object_p): Add nps400 case.

2016-03-21arc: Remove EF_ARC_CPU_GENERIC constant.Andrew Burgess2-74/+76
The constant EF_ARC_CPU_GENERIC is defined in the include/elf/arc.h file, and is used in a few places in binutils, however, this constant should never make it into the elf header flags; we always set a valid cpu type in the assembler, which should then be copied over during linking. There are some non-gnu arc compilers that don't write an architecture type into the e_flags field, instead leaving the field as 0, which is the EF_ARC_CPU_GENERIC value. This non-gnu compiler uses the machine type to distinguish between the old and newer arc architectures, setting the machine type to EM_ARC_COMPACT for old arc600, arc601, and arc700 architectures, while using EM_ARC_COMPACT2 for newer arcem and archs architectures. Previously when displaying the machine flags for an older EM_ARC_COMPACT machine, if the e_flags had not been filled in, then we relied on the default case statement to display the message "Generic ARCompact", while in the EM_ARC_COMPACT2 case we specifically handled EF_ARC_CPU_GENERIC to print "ARC Generic", leaving the default case to print a message about unrecognised cpu flag. After this commit EF_ARC_CPU_GENERIC has been removed, for both machine types EM_ARC_COMPACT and EM_ARC_COMPACT2 we now rely on the default case statement to handle the situation where the e_flags has not been filled in. The message displayed is now "Unknown ARCompact" (for older arc architectures) and "Unknown ARC" (for the newer architectures). The switch from "Generic" to "Unknown" in the message string is for clarity, calling the file "Generic" can give the impression that the file is compiled for a common sub-set of the architectures, and would therefore run on any type of machine (or at least any type of new or old machine depending on if the machine type is ARC or ARCv2). However, this was not what "Generic" meant, it really meant "Unknown", so that's what we now say. As part of the merging of the readelf flag reading code, I have unified the strings used in displaying the ELF ABI. This means that for older arc machines (arc600, arc601, and arc700) the string used for the original ABI, and ABIv2 have changed, the current ABIv3 remains the same. For the newer architectures (arcem and archs) the abi strings remain unchanged in all cases. bfd/ChangeLog: * elf32-arc.c (arc_elf_print_private_bfd_data): Remove use of EF_ARC_CPU_GENERIC. (arc_elf_final_write_processing): Don't bother setting cpu field in e_flags, this will have been set elsewhere. binutils/ChangeLog: * readelf.c (get_machine_flags): Move arc processing into...

2016-03-21arc/gas: default mach is arc700, initialised in md_beginAndrew Burgess2-1/+6
This commit restructures the selection of the default cpu/mach so that the choice is made from md_begin (if the user has not provided a command line choice). This will reduce the amount of change needed in a later patch. At the request of Synopsys, the default architecture changes to ARC700 from this commit, previously the default was a non-existent super-architecture that contained all instructions from all arc variants. There's some clean up associated with removing the default merged architecture, and a small test fix now that the default is ARC700. binutils/ChangeLog: * testsuite/binutils-all/objdump.exp (cpus_expected): Add ARC700 to the architecture list. gas/ChangeLog: * config/tc-arc.c (arc_target): Delay initialisation until arc_select_cpu.
