* Drop 'missing mapping symbols' warning for arm and aarch64.Han Shen2015-09-293-13/+10
| | | | | | | | | | | | | | | | | | | | | | | | | The psABI (AAELF) says this about mapping symbols: 4.6.5.1 Section-relative mapping symbols Mapping symbols defined in a section define a sequence of half-open address intervals that cover the address range of the section. Each interval starts at the address defined by the mapping symbol, and continues up to, but not including, the address defined by the next (in address order) mapping symbol or the end of the section. A section must have a mapping symbol defined at the beginning of the section; however, if the section contains only data then the mapping symbol may be omitted. That makes it pretty clear that, in the absence of a mapping symbol, the entire section can be treated as data. gold/ChangeLog: * aarch64.cc (AArch64_relobj::scan_errata): Drop missing symbol warning. * arm.cc (Arm_relobj::scan_section_for_cortex_a8_erratum): Drop missing symbol warning.

* Patch for gold internal error while fixing erratum 843419.Han Shen2015-07-292-4/+56
| | | | | | | | | | | | | | | | | | | The crash reason is that the insn to be moved to stub may be a relocation spot, so instead of placing the origin insn (that is insn before-relocation) to the stub, I have to place the relocated one.

* Fix DT_MIPS_RLD_MAP_REL tag for n64 target and 32-bit host.Joseph Myers2015-07-272-1/+7
| | | | | | | | | | | | | | | | | | Cherry-picked from upstream: d5cff5df74b18e1e5ed94de8f4c9adee3ffd95c6 For the case of MIPS n64 target and 32-bit host, the computation of the DT_MIPS_RLD_MAP_REL tag involves sdyn->output_section->vma + sdyn->output_offset (64-bit) being added to b (32-bit host pointer), so losing the high part and resulting in an incorrect DT_MIPS_RLD_MAP_REL tag, and all dynamically linked glibc tests failing for n64. This patch fixes this (spot-tested with glibc tests; however, I don't have a self-contained testcase for this bug). * elfxx-mips.c (_bfd_mips_elf_finish_dynamic_sections) <DT_MIPS_RLD_MAP_REL>: Add target address to host address difference, not to host pointer.

* [AArch64] Workaround for cortex-a53 erratum 843419Marcus Shawcroft2015-03-309-14/+639
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 the erratum. 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. 2015-03-30 Tejas Belagod <tejas.belagod@arm.com> Marcus Shawcroft <marcus.shawcroft@arm.com> Jiong Wang <jiong.wang@arm.com> * bfd-in.h (bfd_elf64_aarch64_set_options) (bfd_elf32_aarch64_set_options): Add parameter. * bfd-in2.h: Regenerated. * elfnn-aarch64.c (aarch64_erratum_843419_stub) (_bfd_aarch64_adrp_p, _bfd_aarch64_erratum_843419_sequence_p) (_bfd_aarch64_erratum_843419_stub_name) (_bfd_aarch64_erratum_843419_fixup) (_bfd_aarch64_erratum_843419_scan) (_bfd_aarch64_erratum_843419_branch_to_stub) (_bfd_aarch64_erratum_843419_p): Define.

* [AArch64] Implement branch over stub section.Marcus Shawcroft2015-03-305-48/+68
| | | | | | | | | | | | | 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.

* [AArch64] Refactor generation of 835769 workaround stubs.Marcus Shawcroft2015-03-301-104/+28
| | | | | | | | | | | | | | | | | This patch recognizes that we only need to perform one scan for the 835769 errata and that this scan can take place before we insert branch stubs. The erratum scan code is relocated and adjusted to create stub entries directly rather than populating an intermediate representation. Since stub entries are created immediately we can drop the adhoc stub size adjustment code and allow the generic stub sizing code to deal with 835769 stub entries. This patch restructures the code but does not change the workaround used to deal with erratum 83679, the exact placement of workaround stubs in the final image may change slightly after this patch due to stubs being created in a different order.

* Fixed Cortex-A53 Erratum 835769 -- LD segfaults with unordered maps.Tejas Belagod2015-03-301-0/+27
| | | | | | | | | | | | | | | | | | | The BFD/LD patch for Cortex-A53 erratum 835769 (https://sourceware.org/ml/binutils/2014-10/msg00199.html) does not handle a particular case of the AArch64 ELF ABI where mapping symbols are allowed to be unordered in the symbol table (not in address order). The unordering causes section maps to be traversed with incorrect span boundaries (in the erratum scanning function) which causes memory faults. The attached patch fixes this issue by ordering the section maps by their 'vma' before starting to traverse them. While this is not an issue with a the GNU toolchain, it is a potential issue with Clang/LLVM. We have observed at least one case where LLVM generates an ELF object with mapping symbols unordered in the symbol table and causes a fault. We have been unable to construct a test case with the GNU toolchain. We have verified by manual inspection the correctness of the traversal with this patch for an LLVM-generated ELF object which triggered this issue. This patch has been bootstrapped on aarch64-linux and regressed.
