      Backport trunk patch for not applying dynamic relocs. · 6579e31a
      Han Shen authored
      Note, there is a small change from the origin patch - while in the
      upstream patch, the option --no-apply-dynamic is default off, it is on
      by default in this CL.
      
      This should not bring any changes to android or chromeos, because the
      relocation value this CL changes is not used by chromeos, and is not
      used by android either (after the fix in bionic months ago).
      
      The backported patch is -
      
        commit 0eccf19f96d6218dd7c2f8d13f0546c2b942cc08

        Date:   Thu Nov 5 12:24:14 2015 -0800
      
            Add aarch64-specific --no-apply-dynamic-relocs option.
      
            With --no-apply-dynamic-relocs on aarch64 targets, gold will not
            apply
            link-time values for absolute relocations that become dynamic
            relocations.
            This provides a workaround for broken Android dynamic linkers that
            use
            the link-time value as an extra addend to the relocation.

      Drop 'missing mapping symbols' warning for arm and aarch64. · 1c1d236d
      Han Shen authored
      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.

      Patch for gold internal error while fixing erratum 843419. · ec8f12bc
      Han Shen authored
      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.
      Note the relocation involved is non-pc-relative, so it is safe to move
      the relocated insn.

      Fix DT_MIPS_RLD_MAP_REL tag for n64 target and 32-bit host. · 7e80b87f

      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 843419 · a9dedea6
      Marcus Shawcroft authored
      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.

      [AArch64] Implement branch over stub section. · 15c4812b
      Marcus Shawcroft authored
      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 section_group[] representation. · 2775e1f7
      Marcus Shawcroft authored
      Change the behaviour of section_group[] such that .stub_sec points to
      the stub section attached to the indexed section rather than the stub
      section attached to the link_section pointed to be the index section.
      
      This provides a mechanism to get to the stub section following any
      input section.  While still allowing the section grouping mechanism to
      find the section group stub section associated with an input section
      by first following the link_sec pointer.
