Use gdb::byte_vector in target_write_memory
Pedro pointed out that target_write_memory should use gdb::byte_vector rather than std::vector<unsigned char>. gdb/gdbserver/ChangeLog 2019-08-15 Tom Tromey <tromey@adacore.com> * target.c (target_write_memory): Use gdb::byte_vector. |

Replace write_inferior_memory with target_write_memory
target_write_memory is just a simple wrapper for write_inferior_memory. Because target_write_memory is needed for gdbsupport, and because gdb uses the name "target_write_memory" everywhere, this patch renames write_inferior_memory and removes the wrapper. I think this brings gdb and gdbserver slightly more in sync. gdb/gdbserver/ChangeLog 2019-08-15 Tom Tromey <tromey@adacore.com> * tracepoint.c (write_inferior_data_pointer) (write_inferior_integer, write_inferior_int8) (write_inferior_uinteger, m_tracepoint_action_download) (r_tracepoint_action_download, x_tracepoint_action_download) (l_tracepoint_action_download, clear_inferior_trace_buffer) (download_agent_expr, download_tracepoint_1) (download_trace_state_variables, upload_fast_traceframes): Update. * server.c (gdb_write_memory): Update. * remote-utils.c (relocate_instruction): Update. * proc-service.c (ps_pdwrite): Update. * mem-break.c (remove_memory_breakpoint) (delete_fast_tracepoint_jump, set_fast_tracepoint_jump) (uninsert_fast_tracepoint_jumps_at) (reinsert_fast_tracepoint_jumps_at): Update. * linux-x86-low.c (append_insns) (i386_install_fast_tracepoint_jump_pad) (amd64_write_goto_address, i386_write_goto_address): Update. * linux-s390-low.c (append_insns, s390_write_goto_address): Update. * linux-ppc-low.c (ppc_relocate_instruction) (ppc_install_fast_tracepoint_jump_pad, emit_insns) (ppc_write_goto_address): Update. * linux-aarch64-low.c (append_insns): Update. * target.h (struct target_ops): Update.

Simplify write_inferior_memory
gdbserver's write_inferior_memory uses a static variable to avoid memory leaks, and has a comment referring to the lack of cleanups. This patch removes this comment and the code in favor of a straightforward use of std::vector. gdb/gdbserver/ChangeLog 2019-08-15 Tom Tromey <tromey@adacore.com> * target.c (write_inferior_memory): Use std::vector. |

[PR build/24886] disable glibc mcheck support
This patch drops gdb's configury support for glibc's mcheck function. It has been observed to cause false abort()s, because it is thread-unsafe yet interposes every malloc/free operation. So if any library transitively used by gdb also uses threads, then these functions can easily corrupt their own checking data. These days, gcc ASAN and valgrind provide high quality checking, and mcheck is apparently itself being slowly deprecated. So, let's stop linking to it. Attached patch drops the autoconf/Makefile machinery for both gdb and gdbserver. No testsuite-visible impact. IMHO not worth mentioning in NEWS.

Arm: Remove unused feature files and tests
Remove the xml tests. Now that it has been proven the new descriptions are identical, there is no need to keep testing that. Also, it would prevent the old xml files from being removed.

Rename common to gdbsupport
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

i386/AArch64: Remove old xml tests
Both the i386, X86_64 and AArch64 builds of gdbserver include a bunch of legacy xml files, dat files and auto generated C files, when building for unit test. These tests exists back from when feature target descriptions were added to prove that the new target descriptions were identical to the original older versions. The old files are not used for anything other than these tests. Now that this has been proven, we are not gaining anything by keeping the original files and tests. Should new functionality be added, it would break the tests, unless the functionality was backported to the xml. There is no requirement that we must match the exact xml from N releases ago. It adds obfuscation, where as the feature target descriptions were meant to simplify the code. In addition, there are a bunch of xml and dat files which are completely unused. This patch removes the selftests and the target descriptions from gdbserver. Update the unittest to allow 0 tests (note, this failed on other targets that never had any tests). gdb/ChangeLog: * aarch64-tdep.c: Remove xml self tests. * amd64-linux-tdep.c: Likewise. * amd64-tdep.c: Likewise. * i386-linux-tdep.c: Likewise. * i386-tdep.c: Likewise. gdb/gdbserver/ChangeLog: * configure.srv: Remove legacy xml. * linux-aarch64-low.c (initialize_low_arch): Remove initialize_low_tdesc call. * linux-aarch64-tdesc-selftest.c: Remove file. * linux-aarch64-tdesc.h (initialize_low_tdesc): Remove. * linux-x86-low.c (initialize_low_arch): Remove initialize_low_tdesc call. * linux-x86-tdesc-selftest.c: Remove file. * linux-x86-tdesc.h (initialize_low_tdesc): Remove. gdb/testsuite/ChangeLog: * gdb.server/unittest.exp: Allow 0 unit tests to run. |

Move gnulib to top level
This patch moves the gdb/gnulib subdirectory to the top level. It adjusts the top-level build system to build gnulib when necessary, and changes gdb to use this. However, gdbserver still builds its own copy of gnulib, just from the new source location. A small hack was needed to ensure that gnulib is only built when gdb is enabled. The Makefile only provides an ordering -- the directory must be mentioned in configdirs to actually be compiled at all. Most of the patch is just a "git mv" of gnulib, though a few minor path adjustments were needed in some files there. Tested by the buildbot. ChangeLog 2019-06-14 Tom Tromey <tom@tromey.com> * MAINTAINERS: Add gnulib. * gnulib: New directory, move from gdb/gnulib. * configure.ac (host_libs): Add gnulib. * configure: Rebuild. * Makefile.def (host_modules, dependencies): Add gnulib. * Makefile.in: Rebuild. gdb/ChangeLog 2019-06-14 Tom Tromey <tom@tromey.com> * gnulib: Move directory to top-level. * configure.ac: Don't configure gnulib. * configure: Rebuild. * common/common-defs.h: Use new path to gnulib. * Makefile.in (GNULIB_BUILDDIR): Now ../gnulib.

Move gdb's xmalloc and friends to new file
When "common" becomes a library, linking will cause a symbol clash, because "xmalloc" and some related symbols are defined in that library, libiberty, and readline. To work around this problem, this patch moves the clashing symbols to a new file, which is then compiled separately for both gdb and gdbserver. gdb/ChangeLog 2019-06-11 Tom Tromey <tom@tromey.com> * common/common-utils.c (xmalloc, xrealloc, xcalloc) (xmalloc_failed): Move to alloc.c. * alloc.c: New file. * Makefile.in (COMMON_SFILES): Add alloc.c. gdb/gdbserver/ChangeLog 2019-06-11 Tom Tromey <tom@tromey.com> * Makefile.in (SFILES): Add alloc.c.

Remove newlines from warnings
ARI pointed out that a recent patch introduced a call to "warning"
with a string that ended in a newline:
https://sourceware.org/ml/gdb-patches/2019-06/msg00000.html
This is generally forbidden, I believe, because warning adds its own
newline.
This patch removes all of the trailing newlines I was able to find. I
searched for 'warning (.*\\n"' and then fixed the ones where the
newline appeared at the end of the string (some had internal
newlines).
Tested on x86-64 Fedora 29.

Introduce and use make_unique_xstrdup
Adds an utility function to make it shorter to write the common case of wrapping an xstrdup with a unique_xmalloc_ptr, and uses it throughout. Note: I tried to put this in common/common-utils.h near skip_spaces, etc. but that is included in common/common-defs.h before common/gdb_unique_ptr.h is included, so it would fail to compile because gdb::unique_xmalloc_ptr isn't defined at that point yet. I tried moving the gdb_unique_ptr.h inclusion before common-utils.h, but that doesn't work because gdb_unique_ptr.h depends on common-utils.h for xfree. gdb/ChangeLog: 2019-06-04 Pedro Alves <palves@redhat.com> * common/gdb_unique_ptr.h (make_unique_xstrdup): New. * ada-lang.c (catch_ada_completer): Use make_unique_xstrdup. * breakpoint.c (condition_completer): Likewise. * cli/cli-dump.c (scan_expression): Likewise. * common/filestuff.c (mkdir_recursive): Likewise. * common/gdb_tilde_expand.c (gdb_tilde_expand_up) * common/pathstuff.c (gdb_realpath, gdb_realpath_keepfile) (gdb_abspath): Likewise. * compile/compile-cplus-types.c (compile_cplus_instance::decl_name): Likewise. * completer.c (complete_explicit_location): (signal_completer, reg_or_group_completer_1): Likewise. * cp-support.c (cp_remove_params_if_any): Likewise. * fbsd-tdep.c (fbsd_core_vnode_path): Likewise. * guile/scm-safe-call.c (gdbscm_safe_eval_string): Likewise. * infcmd.c (strip_bg_char): Likewise. * linespec.c (copy_token_string): Likewise. * mi/mi-main.c (output_cores): Likewise. * psymtab.c (psymtab_search_name): * symfile.c (test_set_ext_lang_command): Likewise. * target.c (target_fileio_read_stralloc): Likewise. * tui/tui-regs.c (tui_reggroup_completer): Likewise. * value.c (complete_internalvar): Likewise. gdb/gdbserver/ChangeLog: 2019-06-04 Pedro Alves <palves@redhat.com> * server.c (captured_main): Use make_unique_xstrdup. |

Fix regression caused by recently added syscall restart code
This line of code...
*(int64_t *) ptr = *(int32_t *) ptr;
...in linux-x86-low.c is not needed (and does not work correctly)
within a 32-bit executable. I added an __x86_64__ ifdef (which is
used extensively elsewhere in the file for like purposes) to prevent
this code from being included in 32-bit builds.
It fixes the following regressions when running on native

On MS-Windows, define _WIN32_WINNT in a single common place.
This changeset defines _WIN32_WINNT to at least 0x0501, the level of Windows XP, unless defined to a higher level, in a single place. It then removes all the overrides of _WIN32_WINNT in individual files as no longer needed. Doing this also solves compilation of windows-nat.c with mingw.org's MinGW, as that file uses CONSOLE_FONT_INFO which needs the XP level to become exposed in the Windows headers, while mingw.org defaults to Windows 9X. gdb/ChangeLog: 2019-05-03 Eli Zaretskii <eliz@gnu.org> * common/common-defs.h [__MINGW32__ || __CYGWIN__]: Define _WIN32_WINNT to the XP level, unless already defined to a higher level. * unittests/parse-connection-spec-selftests.c: * ser-tcp.c: * common/netstuff.c [USE_WIN32API]: Remove the _WIN32_WINNT override. gdb/gdbserver/ChangeLog: 2019-05-03 Eli Zaretskii <eliz@gnu.org> * remote-utils.c: * gdbreplay.c [USE_WIN32API]: Remove the _WIN32_WINNT override. |

gdbserver: Move remote_debug to a single place
A comment in debug.h (written in 2014) states: "We declare debug format variables here, and debug_threads but no other debug content variables (e.g., not remote_debug) because while this file is not currently used by IPA it may be some day, and IPA may have its own set of debug content variables". This has resulted in remote_debug being declared in many .c/.h files throughout gdbserver. It would be much simplier to define it one place. The most logical place to define it is in debug.h, surrounded by #define guards. If IPA is changed, then at that point the variable can be moved elsewhere. gdb/gdbserver/ChangeLog: * debug.c (remote_debug): Add definition. * debug.h (remote_debug): Add declaration. * hostio.c (remote_debug): Remove declaration. * remote-utils.c (struct ui_file): Likewise.

Fix amd64->i386 linux syscall restart problem
This commit fixes some failures in gdb.base/interrupt.exp when debugging a 32-bit i386 linux inferior from an amd64 host. When running the following test... make check RUNTESTFLAGS="--target_board unix/-m32 interrupt.exp" ... without this commit, I see the following output: FAIL: gdb.base/interrupt.exp: continue (the program exited) FAIL: gdb.base/interrupt.exp: echo data FAIL: gdb.base/interrupt.exp: Send Control-C, second time FAIL: gdb.base/interrupt.exp: signal SIGINT (the program is no longer running) ERROR: Undefined command "". ERROR: GDB process no longer exists === gdb Summary === When the test is run with this commit in place, we see 12 passes instead. This is the desired behavior. Analysis: On Linux, when a syscall is interrupted by a signal, the syscall may return -ERESTARTSYS when a signal occurs. Doing so indicates that the syscall is restartable. Then, depending on settings associated with the signal handler, and after the signal handler is called, the kernel can then either return -EINTR or can cause the syscall to be restarted. In this discussion, we are concerned with the latter case. On i386, the kernel returns this status via the EAX register. When debugging a 32-bit (i386) process from a 64-bit (amd64) GDB, the debugger fetches 64-bit registers even though the process being debugged is 32-bit. Since we're debugging a 32-bit target, only 32 bits are being saved in the register cache. Now, ideally, GDB would save all 64-bits in the regcache and then would be able to restore those same values when it comes time to continue the target. I've looked into doing this, but it's not easy and I don't see many benefits to doing so. One benefit, however, would be that EAX would appear as a negative value for doing syscall restarts. At the moment, GDB is setting the high 32 bits of RAX (and other registers too) to 0. So, when GDB restores EAX just prior to a syscall restart, the high 32 bits of RAX are zeroed, thus making it look like a positive value. For this particular purpose, we need to sign extend EAX so that RAX will appear as a negative value when EAX is set to -ERESTARTSYS. This in turn will cause the signal handling code in the kernel to recognize -ERESTARTSYS which will in turn cause the syscall to be restarted. This commit is based on work by Jan Kratochvil from 2009: https://sourceware.org/ml/gdb-patches/2009-11/msg00592.html Jan's patch had the sign extension code in amd64-nat.c. Several other native targets make use of this code, so it seemed better to move the sign extension code to a linux specific file. I also added similar code to gdbserver. Another approach is to fix the problem in the kernel. Hui Zhu tried to get a fix into the kernel back in 2014, but it was not accepted. Discussion regarding this approach may be found here: https://lore.kernel.org/patchwork/patch/457841/ Even if a fix were to be put into the kernel, we'd still need some kind of fix in GDB in order to support older kernels. Finally, I'll note that Fedora has been carrying a similar patch for at least nine years. Other distributions, including RHEL and CentOS have picked up this change and have been using it too. gdb/ChangeLog: * amd64-linux-nat.c (amd64_linux_collect_native_gregset): New function. (fill_gregset): Call amd64_linux_collect_native_gregset instead of amd64_collect_native_gregset. (amd64_linux_nat_target::store_registers): Likewise. gdb/gdbserver/ChangeLog: * linux-x86-low.c (x86_fill_gregset): Sign extend EAX value when using a 64-bit gdbserver. |

Use find_thread_in_random in select_event_lwp
I noticed that find_thread_in_random duplicates the code in find_thread_in_random, so this patch changes the latter to use the former. There are two other spots in gdb that do this, but to unify all of them would require switching some code from using the "iterate over" idiom to using iterators. Another possible improvement is that find_thread_in_random could be made single-pass using reservoir sampling. Tested by the buildbot. gdb/gdbserver/ChangeLog 2019-04-09 Tom Tromey <tromey@adacore.com> * linux-low.c (select_event_lwp): Use find_thread_in_random. |

Replace throw_exception with throw in some cases
This replaces throw_exception with "throw;" when possible. This was
written by script. The rule that is followed is that uses of the
form:
catch (... &name)
{
...
throw_exception (name);
}
... can be rewritten. This should always be safe, because exceptions
are caught by const reference, and therefore can't be modified in the
body of the catch.

gdbserver: When attaching, add process before lwps
The recent BP/WP changes for AArch64 swapping the order in add_lwp() so that the process was added before the lwp. This was due to the lwp creation requiring the process data. This also needs changing in linux_attach(). Also add additional checks to make sure cannot attach to the same process twice. Add test case for this - do this by splitting attach.exp into distinct pass and error case sections. Fixes gdb.server/ext-attach.exp on Aarch64. gdb/gdbserver/ChangeLog: * linux-low.c (linux_attach): Add process before lwp. * server.c (attach_inferior): Check if already attached. gdb/testsuite/ChangeLog: * gdb.base/attach.exp: Add double attach test. |

Normalize include guards in gdb
While working on my other scripts to deal with gdb headers, I noticed
that some files were missing include guards. I wrote a script to add
the missing ones, but found that using the obvious names for the
guards ran into clashes -- for example, gdb/nat/linux-nat.h used
"LINUX_NAT_H", but this was also the script's choice for
gdb/linux-nat.h.
So, I changed the script to normalize all include guards in gdb. This
patch is the result.
As usual the script is available here:
https://github.com/tromey/gdb-refactoring-scripts
Tested by rebuilding; I also ran it through "Fedora-x86_64-m64" on the
buildbot.

[PR gdb/23985] Fix libinproctrace.so build
The IPA objects currently may use gnulib replacement apis, which is wrong: gnulib is not linked into the produced dso and it cannot be because it is not built with -fPIC -fvisibility=hidden. The gnulib replacement detection is broken under cross compilation: for targets other than *-gnu*, replacements are enabled that depend on execution time detection. This causes unnecessary build failure when the target has proper support for the replaced api. This fix tries to undo the replacements, which is tricky because the gnulib headers are still used for various compile time fixups and there is no simple knob in gnulib to only turn the replacements off. Without this workaround gdb fails to cross build to non-gnu targets: ld: tracepoint-ipa.o: in function `gdb_agent_helper_thread(void*)': gdb/gdbserver/tracepoint.c:7221: undefined reference to `rpl_strerror' ... Makefile:434: recipe for target 'libinproctrace.so' failed gdb/gdbserver/ChangeLog: PR gdb/23985 * Makefile.in (IPAGENT_CFLAGS): Add UNDO_GNULIB_CFLAGS. (UNDO_GNULIB_CFLAGS): Undo gnulib replacements. |

gdbserver: When attaching, add process before lwps
The recent BP/WP changes for AArch64 swapping the order in add_lwp() so that the process was added before the lwp. This was due to the lwp creation requiring the process data. This also needs changing in linux_attach(). Fixes gdb.server/ext-attach.exp on Aarch64. (This regression was hidden due to the racy nature of the gdb.server tests - now they are no longer racy it'll be easier to spot. Also checked X86). gdb/gdbserver/ChangeLog: 2019-01-25 Alan Hayward <alan.hayward@arm.com> * linux-low.c (linux_attach): Add process before lwp. |

Don't use -I for common subdirectory
This changes the Makefiles to remove the -I for the common/ subdirectory. This will enforce the rule that includes must use the 'common/filename.h' form. gdb/ChangeLog 2019-01-25 Tom Tromey <tom@tromey.com> * Makefile.in (GDB_CFLAGS): Don't add -I for common. gdb/gdbserver/ChangeLog 2019-01-25 Tom Tromey <tom@tromey.com> * Makefile.in (INCLUDE_CFLAGS): Don't add -I for common. |
