c40c7bf (Remove features/tic6x-*.c files) doesn't remove features/tic6x-c62x-linux.c. This patch removes it. gdb: 2017-10-18 Yao Qi <yao.qi@linaro.org> * features/tic6x-c62x-linux.c: Remove.
2017-10-18PR22303, print_core_note out of bounds readAlan Modra2-27/+35
The print_core_note change here fixes the PR, the rest is making readelf a little more bombproof against maliciously crafted binaries. PR 22303 * readelf.c (print_core_note): Ensure "count" sanity check calculation doesn't overflow. (process_notes_at): Perform note namesz and descsz checks using unsigned comparisons against data remaining. Catch alignment overflow of namesz and descsz too. Don't allocate a temp for terminating "name" when there is space available before descdata.

2017-10-18[GOLD] Fix powerpc64 optimization of TOC accessesAlan Modra2-2/+9
Fixes a thinko. Given code that puts variables into the TOC (a bad idea, but some see the TOC as a small data section) this bug could result in an attempt to optimize a sequence that should not be optimized. * powerpc.cc (Target_powerpc::Scan::local): Correct dst_off calculation for TOC16 relocs.

2017-10-17Really make the native-stdio-gdbserver board non-remotePedro Alves2-0/+5
I've noticed now that due to a last-minute change, commit 739b3f1d8ff7 ("Make native gdbserver boards no longer be "remote" (in DejaGnu terms)") managed to miss loading "local-board" in the native-stdio-gdbserver board... gdb/testsuite/ChangeLog: 2017-10-17 Pedro Alves <palves@redhat.com> * boards/native-stdio-gdbserver.exp: Load "local-board".

2017-10-17Add several "quit with live inferior" testsPedro Alves3-0/+210
In my multi-target branch, I had managed to break GDB exiting successfuly in response to "quit" or SIGHUP/SIGTERM when: - you're debugging with "target extended-remote", - have more than one inferior loaded in gdb, some running, and at least one not running, and, - quit gdb with the inferior that is not running yet selected. The testsuite still passed cleanly anyway. I only noticed because I was left with a bunch of core dumps in the gdb/testsuite/ directory -- the testsuite infrastructure closes GDB's pty after running each testcase, which results in GDB getting a SIGHUP and should make GDB exit gracefully. If GDB crashes at that point though, there's no indication about it in gdb.sum/gdb.log. This commit adds a multitude of tests exercising quitting GDB with live inferiors, some of which would have caught the problem. gdb/testsuite/ChangeLog: 2017-10-17 Pedro Alves <palves@redhat.com> * gdb.base/quit-live.c: New file. * gdb.base/quit-live.exp: New file.

2017-10-17Remove obsolete assertion from regcache.cTom Tromey2-1/+4
When building I got: ../../binutils-gdb/gdb/regcache.c:935:24: error: the address of ‘ssize_t read(int, void*, size_t)’ will never be NULL [-Werror=address] This happens because "read" used to be a parameter to this function, which was then removed; but the assertion wasn't updated. I don't think the assertion is relevant any more, to this removes it. I'm checking it in as obvious. 2017-10-17 Tom Tromey <tom@tromey.com> * regcache.c (regcache::xfer_part): Remove assertion.
2017-10-17PR22307, Heap out of bounds read in _bfd_elf_parse_gnu_propertiesAlan Modra2-9/+15
When adding an unbounded increment to a pointer, you can't just check against the end of the buffer but also must check that overflow doesn't result in "negative" pointer movement. Pointer comparisons are signed. Better, check the increment against the space left using an unsigned comparison. PR 22307 * elf-properties.c (_bfd_elf_parse_gnu_properties): Compare datasz against size left rather than comparing pointers. Reorganise loop.

2017-10-16Make native gdbserver boards no longer be "remote" (in DejaGnu terms)Pedro Alves8-124/+157
This commit finally clears the "isremote" flag in the native-gdbserver and native-stdio-gdbserver boards. The goal is to make all "native" boards be considered not remote in DejaGnu terms, like the native-extended-gdbserver board is too. DejaGnu automatically considers boards remote if their names don't match the local hostname. That means that native-gdbserver and native-extended-gdbserver are considered remote by default by DejaGnu, even though they run locally. native-extended-gdbserver, however, overrides its isremote flag to force it to be not remote. So we are in that weird state where native-gdbserver is considered remote, and native-extended-gdbserver is considered not remote. A recent set of commits fixed all the problems (and some more) exposed by testing with --target_board=native-gdbserver and --target_board=native-stdio-gdbserver with isremote forced off on x86-64 GNU/Linux. I believe we're good to go now. The native-stdio-gdbserver.exp/remote-stdio-gdbserver.exp boards required deep non-obvious modifications unfortunately... The problem is that if a board is not remote, then DejaGnu doesn't call ${board}_spawn / ${board}_exec at all, and the native-stdio-gdbserver.exp board relies on those procedures being called. To fix that, this commit redesigns how the stdio boards hook into the testing framework to spawn gdbserver. IMO, this is a good change anyway, because the way its done currently is a bit of a hack, and the result turns out to be simpler, even. With this commit, they now no longer load the "gdbserver" generic config, and hook at the mi_gdb_target_load/gdb_reload level instead, making them more like traditional board files. To share code between native-stdio-gdbserver.exp and remote-stdio-gdbserver.exp, a new shared stdio-gdbserver-base.exp file is created. Instead of having each native board clear isremote manually, boards source the new "local-board.exp" file. This also adds a new section to testsuite/README file discussing local/remote/native, so that we can easily refer to it. gdb/testsuite/ChangeLog: 2017-10-16 Pedro Alves <palves@redhat.com> Simon Marchi <simon.marchi@polymtl.ca> * README (Local vs Remote vs Native): New section. * boards/local-board.exp: New file, with bits factored out from ... * boards/native-extended-gdbserver.exp: ... here.

2017-10-16ELF: Call check_relocs after opening all inputsH.J. Lu97-3644/+277
For all ELF targers, call check_relocs after opening all inputs and garbage collection. Since the symbol resolution is known, check_relocs can be simplified. Also garbage collection doesn't need to undo what check_relocs has done for symbols which have been garbage collected. Since ELF targets never see the removed sections, gc_sweep_hook can be removed from elf_backend_data and we can avoid GOT/PLT with garbage collection now. Set link_info.check_relocs_after_open_input to TRUE for all linker targets which use ELF linker and update garbage collection tests to remove unused GOT section. ldemul_after_check_relocs is added for powerpc to support --secure-plt, --bss-plt and --sdata-got. Tested natively without regressions on i686, x86-64 and x32.

2017-10-16Regenerate gdbserver/configureYao Qi2-3/+14
4fa7574 (Fix gdb 8.1 Solaris compilation) changes warning.m4 and updates configure, but gdbserver/configure is not updated. gdb/gdbserver: 2017-10-16 Yao Qi <yao.qi@linaro.org> * configure: Regenerated.

features/*.c are generated from *.xml files, in order to get pre-defined target descriptions, (for native debugging, for example). However, these pre-generated tdesc_tic6x_* are not used in GDB at all. This patch removes features/tic6x-*.c files. gdb: 2017-10-16 Yao Qi <yao.qi@linaro.org> * features/Makefile (XMLTOC): Remove tic6x-*.xml. * features/tic6x-c62x.c: Remove. * features/tic6x-c64x-linux.c: Remove. * features/tic6x-c64x.c: Remove. * features/tic6x-c64xp-linux.c: Remove. * features/tic6x-c64xp.c: Remove. * tic6x-linux-tdep.c (_initialize_tic6x_linux_tdep): Don't call initialize_tdesc_tic6x_*_linux functions. * tic6x-tdep.c (_initialize_tic6x_tdep): Don't call initialize_tdesc_tic6x_* functions.

tic6x-uclinux GDBserver uses linux target descriptions, instead of these non-linux target descriptions. So we can remove these *.dat files. gdb: 2017-10-16 Yao Qi <yao.qi@linaro.org> * features/Makefile (WHICH): Remove tic6x-c64xp, tic6x-c64x tic6x-c62x. * regformats/tic6x-c62x.dat: Remove. * regformats/tic6x-c64x.dat: Remove. * regformats/tic6x-c64xp.dat: Remove.
2017-10-15Fix GDB build without expatSimon Marchi2-1/+6
An earlier patch of mine changed parse_traceframe_info to make it return a unique_ptr. I forgot to update the version of the function used in an expat-less build, this patch fixes it. gdb/ChangeLog: * tracepoint.c (parse_traceframe_info): Return a unique_ptr (the !HAVE_LIBEXPAT version).
