* Backport to fix race condition calling select_as_default_target()Andrew Hsieh2015-03-301-1/+1

* Fix as to ignore --save-tempsAndrew Hsieh2015-03-301-0/+7
| | | | | | | | | | | mips/gcc4.6 is now built with binutils-2.24 to be consistant with gcc4.8 and gcc4.9 on nan handling. Unfortunately gcc4.6 pass on -save-temps to not recognized by "as". gcc4.6 is normally built with binutils-2.21 which has fix for as to accept but ignore -save-temps. This CL catptures the same fix in binutils-2.21 Change-Id: I58095a67810f2bcf6e7594383002247a9491a901

* Fix extraneous warning about executable stack.Cary Coutant2014-12-022-3/+17
| | | | | | | | | | | | | | | | | | | | PR gold/17578 notes that gold will print a warning about an executable stack when the -z execstack option is given, even when there is no --warn_execstack option. The warning is completely useless and unexpected, since the user explicitly requested an executable stack, and did not even ask for warnings. This patch fixes that, and adds an extra warning when --warn_execstack and -z noexecstack are both given and an input file requires an executable stack. gold/ PR gold/17578 * layout.cc (Layout::layout_gnu_stack): Don't warn when -z execstack is given. (Layout::create_executable_stack_info): Warn when -z noexecstack is given but some inputs require executable stack. Change-Id: I7b15682af81d3c52057473d347f83a768e087ffa
* Fixed Cortex-A53 Erratum 835769 -- LD segfaults with unordered maps.Tejas Belagod2014-12-021-0/+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. Change-Id: I75622055b01eeb3038d5600c9eea395585e54aca

Lu <hjl.tools@gmail.com> Date: Tue May 27 12:19:33 2014 -0700 Properly handle 64-bit GOT relocations This patch fixes 2 issues: 1. Since the GOT offset is always negative, we need to use signed int to support 64-bit GOT relocations. 2. R_X86_64_PLTOFF64 uses the address of GLOBAL_OFFSET_TABLE, which is the address of the .got.plt section, not the .got section. commit 7849f6d8dc37fc3da2fec06ac1d47afbe4b81059 Author: Cary Coutant <ccoutant@google.com> Date: Wed Apr 23 15:17:16 2014 -0700 Add missing break statement for case elfcpp::R_X86_64_PLTOFF64. gold/ * x86_64.cc (Target_x86_64::Relocate::relocate): Add missing break.

* [2.24] fix MIPS static executable segfaultAndrew Hsieh2014-05-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previous commit f25603579c0a04b3d5099259cf54c5b3c8775b78 isn't complete because .ctors/.dtors in crtbegin*/crtend* aren't excluded from .init_array/.fini_array. Static executable (eg. $NDK/tests/device/static-executable) causes "Bus Error" because call_array() in __libc_init() call ffffffff from __INIT_ARRAY__ not properly terminaed by NULL. Disassembly of section .init_array: 000b42ac <__INIT_ARRAY__>: b42ac: ff ff ff ff 000b42b0 <__CTOR_LIST__>: b42b0: ff ff ff ff dc 09 08 00 f8 09 08 00 00 00 00 00 000b42c0 <__CTOR_END__>: b42c0: 00 00 00 00 Note that Android uses .init/.fini_array (move away from .ctors/.dtors), but we can't simply remove _CTOR* from crtbegin_static/dynamic.o because older device (eg. ICS) call_array() on CTOR_LIST The correct fix is to exclude them Thanks to icebergfu@gmail.com for identifying the issues. Change-Id: I7a955753baa00fd486cc5a37362ab91c3a21d1e1
