GDB 8.2 will use C++ to compile in Android, and it will cause the problem that extern variables from libthread_db will be compiled into C++ symbols and cause a linker error.

2018-08-20Fix debugging of stripped PIE executables with padded PT_TLSndk-r19cndk-r19bndk-r19-beta2ndk-r19-beta1ndk-r19ndk-release-r19Michael Spang
Certain PIE executables produced by gold cannot be debugged by gdb after being stripped. GDB requires program headers of PIE executables to match, and those checks may fail due to adjustments made during stripping. One case of this occurs because strip recomputes the memsz of PT_TLS and does not add alignment, while gold does. This is another variant of PR 11786, so apply the same fix of relaxing the program header matching. gdb/ChangeLog: PR gdb/11786 * solib-svr4.c (svr4_exec_displacement): Ignore memsz fields for PT_TLS segments. gdb/testsuite/ChangeLog: PR gdb/11786 * gdb.base/gcore-tls-pie.c: New file. * gdb.base/gcore-tls-pie.exp: New file.

2018-05-01bfd: add experimental support for SHT_RELR sections.ndk-r18bndk-r18-beta2ndk-r18-beta1ndk-release-r18Rahul Chaudhry
This change adds experimental support for SHT_RELR sections, proposed here: https://groups.google.com/forum/#!topic/generic-abi/bX460iggiKg This is a subset of the change that was merged into the aosp/binutils repo (https://android-review.googlesource.com/572669). It contains the definitions for the new section type / dynamic tags, and support in bfd for recognizing the new section type. Gdb uses bfd to read the program binary, and without this support, it fails to detect some architecture related settings. Bug: https://bugs.chromium.org/p/chromium/issues/detail?id=836845 Test: Built gdb inside a Chrome OS chroot. Verified that architecture auto-detection works for an x86_64 binary containing a '.relr.dyn' section. The message "don't know how to handle section `.relr.dyn'" is no longer printed.

2016-09-16Prevent segfault in GDB when searching for architecture matchesBhushan Attarde
Cherry-picked from upstream: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=5d9bbb73c1df68741048c3d0f837b50c289ea608 This fixes gdb host crash when trying to read symbols from target. While patch is arch-neutral, we could only reproduce the issue for mips. * format.c (struct bfd_preserve): New "build_id" field. (bfd_preserve_save): Save "build_id". (bfd_preserve_restore): Restore "build_id". From https://sourceware.org/ml/gdb-patches/2016-09/msg00070.html : Currently the "build_id" field of "struct bfd" is not preserved by "struct bfd_preserve" when "bfd_check_format_matches" is going through all target vectors trying to find a compatible target vector. This leads to a segmentation fault in GDB. Consider a case where one compatible target vector has already been found (so the subset of bfd state is saved in struct bfd_preserve) and then an attempt to find a better match fails after it has modified bfd's build_id pointer. Since this attempt is failed, all its side effects will be undone and all memory allocations done by this vector will be free'd. This will eventually free the memory block that build_id pointer is pointing to. This free'd block then gets reallocated and used for storing something else -- leaving build_id pointing to incorrect contents. This patch adds "build_id" pointer to "struct bfd_preserve" so that it will be preserved on success which can then be recoverable on failure. Change-Id: I3e81c3a8a1d25869659bbf99bebe8b00062cea72

2016-06-24Define DT_MIPS_RLD_MAP_REL in code, until renamed in sysrootndk-r13-beta1Nikola Veljkovic
Gdbserver is using prebuilts/ndk sysroot, where we haven't updated the tag. There we have old DT_MIPS_RLD_MAP2 tag defined (just a different name, same value). Until sysroot used to build gdbserver is fixed, we need to define the tag directly in the source code. Updating the tag is the job of: https://android-review.googlesource.com/233345. Workaround is based on change: I4dd0969c1a6f847fd5b11b1206c7bd6ef1f30137 Verified on: mips, mips64, arm, arm64 emulators. Change-Id: I552654458d506e219d19c7345d127c6bb2337997
