* Create an unified binutils source tree for both Android and ChromiumOS.Han Shen2015-11-19407-3791/+4890
| | | | | | | | | | | | | | | | | | | | | | About source code - The base version of this binutils is newer than that of aosp/binutils-2.25, it is based on the binutils that is used to build google products and ChromiumOS. And it contains *all* local Android patches as well as all patches that are cherry-picked from upstream for aosp/binutils-2.25 tree (up to Nov. 5 - 932d71b85). You may find the detailed development history for this binutils tree here - https://chromium.googlesource.com/chromiumos/third_party/binutils/+log/unification (This CL is a combination of all the CLs in it. After this CL is submitted the tree will be identical to https://chromium.googlesource.com/chromiumos/third_party/binutils/+log/unification at 2865a3615d80bd5f82d14d7e0484e84dc052596a) About testing - We tested this binutils for both ChromiumOS and Android. For android, we tested building N4, N5X, N6, N7, N9 using new binutils, we also did a full-build of toolchain (by build.py) and built a N5X image; for ChromiumOS - it passed ChromiumOS toolchain release tests on all 4 platforms (x86, x86_64, arm32 and arm64).

* Plumb --pic-veneer option for gold.Lee Campbell2015-11-053-3/+15
| | | | | | | | | | Cherry-pick of upstream commit cdb061674c044636465e52a8c989b9011f2ec8ac gold/ChangeLog: * arm.cc (Reloc_stub::stub_type_for_reloc): Plumb to stub generation. * options.h (General_options): Add --pic-veneer option. BUG: 25512672
* Fix gold build error at -O0.Than McIntosh2015-10-162-2/+13
| | | | | | | | | | | | | | | | | | | | | Cherrypick of upstream commit 5d7908e0880030628536a0266968a15922574735 Author: Cary Coutant <ccoutant@gmail.com> Date: Thu Jun 11 13:19:38 2015 -0700 Fix gold build error at -O0. In aarch64.cc, Erratum_stub::STUB_ADDR_ALIGN and Reloc_stub::STUB_ADDR_ALIGN are declared as static const int, and initialized in the class body. These values are referenced from outside the class body, and with no optimization, the references go unresolved. gold/ * aarch64.cc (Erratum_stub::STUB_ADDR_ALIGN): Move initialization outside class body. (Reloc_stub::STUB_ADDR_ALIGN): Likewise. Change-Id: I6c0726e624be076e0d0565652a56da5ef761d88a

| | | | | | | | | gold/ChangeLog: * aarch64.cc (Target_aarch64::scan_erratum_843419_span): Use 'gold_info'. (Target_aarch64::scan_erratum_835769_span): USe 'gold_info'. (cherry picked from commit 73854cdd438dc8858290231ebcb682377d71fec2)
* 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. (cherry picked from commit 61163dfaaedb90d78e11c1d79ad1e469daf3da47)
* Remove duplicated option fix_cortex_a53_835769Andrew Hsieh2015-07-301-3/+0
| | | | | | | | | This was added before ld.gold scans for erratum 835769, but GCC has been hard-wired to pass "--fix-cortex-a53-835769" to linker (ld.bfd is default for AArch64 for now) unconditionally in Android platform. Change-Id: I39bacdc2a52d09afdc0993c17b46ac438d1fa246

* 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. Note the relocation involved is non-pc-relative, so it is safe to move the relocated insn. gold/ChangeLog: 2015-06-29 Han Shen <shenhan@google.com> * AArch64.cc (Erratum_stub::Insn_utilities): New typedef. (Erratum_stub::update_erratum_insn): New method. (Stub_table::relocate_stubs): Modified to place relocated insn. (AArch64_relobj::fix_errata): Modified gold_assert.
