2015-05-15Support AMD64/Intel ISAs in assembler/disassemblerH.J. Lu4-4/+12
AMD64 spec and Intel64 spec differ in direct unconditional branches in 64-bit mode. AMD64 supports direct unconditional branches with 16-bit offset via the data size prefix, which truncates RIP to 16 bits, while the data size prefix is ignored by Intel64. This patch adds -mamd64/-mintel64 option to x86-64 assembler and -Mamd64/-Mintel64 option to x86-64 disassembler. The most permissive ISA, which is AMD64, is the default. GDB can add an option, similar to (gdb) help set disassembly-flavor Set the disassembly flavor. The valid values are "att" and "intel", and the default value is "att". to select which ISA to disassemble. binutils/ PR binutis/18386 * doc/binutils.texi: Document -Mamd64 and -Mintel64. gas/ PR binutis/18386 * config/tc-i386.c (OPTION_MAMD64): New.

2015-04-23Delay setting up compressed debug section namesH.J. Lu3-0/+24
When we set up st_name for output section name in elf_fake_sections, we don't know if the compressed DWARF debug section will be smaller. We may end up with compressed DWARF debug sections which are bigger than the uncompressed ones. This patch delays setting up st_name for output DWARF debug section to _bfd_elf_assign_file_positions_for_non_load which will compress the output debug section. We also postpone placement of shstrtab section after DWARF debug sections have been compressed. The net effect is .shstrtab section is now placed after .symtab and .strtab sections. bfd/ PR ld/18277 * compress.c (bfd_compress_section_contents): Remove the write_compress argument.

2015-04-22Rewrite relro adjusting codeAlan Modra2-1/+5
The linker tries to put the end of the last section in the relro segment exactly on a page boundary, because the relro segment itself must end on a page boundary. If for any reason this can't be done, padding is inserted. Since the end of the relro segment is typically between .got and .got.plt, padding effectively increases the size of the GOT. This isn't nice for targets and code models with limited GOT addressing. The problem with the current code is that it doesn't cope very well with aligned sections in the relro segment. When making .got aligned to a 256 byte boundary for PowerPC64, I found that often the initial alignment attempt failed and the fallback attempt to be less than adequate. This is a particular problem for PowerPC64 since the distance between .got and .plt affects the size of plt call stubs, leading to "stubs don't match calculated size" errors. So this rewrite takes a direct approach to calculating a new relro base. Starting from the last section in the segment, we calculate where it must start to position its end on the boundary, or as near as possible considering alignment requirements. The new start then becomes the goal for the previous section to end, and so on for all sections. This of course ignores the possibility that user scripts will place . = ALIGN(xxx); in the relro segment, or provide section address expressions. In those cases we might fail, but the old code probably did too, and a fallback is provided. ld/ * ldexp.h (struct ldexp_control): Delete dataseg.min_base. Add data_seg.relro_offset. * ldexp.c (fold_binary <DATA_SEGMENT_ALIGN>): Don't set min_base.

2015-04-01[AArch64] Workaround for Cortex A53 erratum 843419Marcus Shawcroft4-0/+160
Some early revisions of the Cortex-A53 have an erratum (843419). The details of the erratum are quite complex and involve dynamic conditions. For the purposes of the workaround we have simplified the static conditions to an ADRP in the last two instructions of a 4KByte page, followed within four instructions by a load/store dependent on the ADRP. This patch adds support to conservatively scan for and workaround Cortex A53 erratum 843419. There are two different workaround strategies used. The first is to rewrite ADRP instructions which form part of an erratum sequence with an ADR instruction. In situations where the ADR provides insufficient offset the dependent load or store instruction from the sequence is moved to a stub section and branches are inserted from the original sequence to the relocated instruction and back again. Stub section sizes are rounded up to a multiple of 4096 in order to ensure that the act of inserting work around stubs does not create more errata sequences. Workaround stubs are always inserted into the stub section associated with the input section containing the erratum sequence. This ensures that the fully relocated form of the veneered load store instruction is available at the point in time when the stub section is written.

Ensure that injection of a stub section does not break a link where there is an xpectation that flow of control can pass from one input section to another simply by linking the input sections in series. The solution here is to allow stub sections to be inserted after any input section (existing behaviour), but inject an additional branch at the start of each stub section such that control flow falling into the stub section will branch over the stub section.
