2016-01-08perf testsuite: python 3 fixesSimon Marchi3-7/+17
There are a few errors when trying to run the performance testsuite with Python 3. This commit fixes them. In Python 2, it was possible to use relative imports (importing a module relative to the current one). In Python 3 it isn't. So I use absolute_import from the __future__ module, which allows Python 2 to behave like Python 3, and use the Python 3 syntax. In Python 3, dict.iterkeys doesn't exist anymore. Using dict.keys is a good compromise in this case. gdb/testsuite/ChangeLog: * gdb.perf/lib/perftest/perftest.py: Change relative imports to absolute. (SingleStatisticTestResult.report): Use dict.keys instead of dict.iterkeys.

GDB only stays in extension language for a very short period in this case, but if ctrl-c is pressed at that moment, python extension will handle the SIGINT, and exceptions.KeyboardInterrupt is shown. Language extension is used in GDB side rather than inferior side, so GDB should only change SIGINT handler for extension language when the terminal is ours (not inferior's). This is what this patch does.

2016-01-08Check input interrupt first when reading packetYao Qi2-0/+14
Hi, I see timeout in one of several runs of random-signal.exp like this, $ (set -e; while true; do make check RUNTESTFLAGS="--target_board=native-gdbserver random-signal.exp"; done) In about every five runs, we can see a fail, PASS: gdb.base/random-signal.exp: continue ^CFAIL: gdb.base/random-signal.exp: stop with control-c (timeout) after some investigation, I find '\003' may be discarded by GDBserver when it is expecting '$'. In GDB side, both normal packets and '\003' are sent via function send, but GDBserver may receive them at any time, that is to say, in the receive buffer in GDBserver, '\003' may appear before or after normal packet. However, current GDBserver doesn't handle this case. With this patch applied, I don't see this fail in multiple runs. Although there is still timeout fail, that is a different problem, the next patch will fix it. gdb/gdbserver: 2016-01-08 Yao Qi <yao.qi@linaro.org> * remote-utils.c (getpkt): If c is '\003', call target hook request_interrupt.

2016-01-05Fix PR sim/13418: building with --enable-targets=all failsPedro Alves5-1/+30
Multitarget builds currently fail when: (1) simulator support is enabled (the main --target supports target sim) (2) powerpc is included in the --enable-targets list (3) powerpc is not the main/default target (--target) This is because the powerpc sim provides a non-standard API function sim_spr_register_name which gdb/rs6000-tdep.c utilizes. Since the sim does not yet support multitarget, only the sim (if one exists) for the main target is built. When that target isn't powerpc, this function is not available leading to linking errors: rs6000-tdep.c:(.text+0x1e34d): undefined reference to `sim_spr_register_name' Fix this by only using that API if the sim linked in is the powerpc sim. gdb/ChangeLog: 2016-01-05 Pedro Alves <palves@redhat.com> PR sim/13418 * configure.ac: Define WITH_PPC_SIM when linking in the sim and the target is powerpc*. * configure: Regenerate. * config.in: Regenerate.

2015-12-24[testsuite/Ada] stop using project files when building test programsJoel Brobecker5-31/+34
The current approach when building Ada programs for testing is based on the use of a project file (testsuite/gdb.ada/gnat_ada.gpr). To do that, we pass a number of additional arguments to target_compile, one of them being the project file (via "-P/path/to/gnat_ada.gpr"). This used to work well-enough, but AdaCore is currently working towards removing project-file support from gnatmake (the prefered tool for using project files is gprbuild). So, we need to either switch the compilation to gprbuild, or stop using project files. First, using gprbuild is not always what users will be using to build their applications. So having the option of using gnatmake provides more flexibility towards exactly reproducing past bugs. If we ever need a testcase that requires the use of gprbuild, then I believe support for a new target needs to be added to dejagnu's target_compile. Also, the only real reason behind using a project file in the first place is that we wanted to make it easy to specify the directory where all compilation artifacts get stored. This is a consequence of the organization choice we made for gdb.ada to keep each testcase well organized. It is very easy to achieve that goal without using project files. This is therefore what this patch does: It change gdb_compile_ada to build any program using gnatmake without using a project file (by temporarily changing the current working directory). There is a small (beneficial) side-effect; in the situation where GDB is built in-tree, gnatmake is called as... % gnatmake [...] unit.adb ... which means that the debugging info in unit.o will say contain a filename whose name is 'unit.adb', rather than '/path/to/unit.adb'. This also better matches what users might typically do. But the side- effect is that the unit name in the GDB output is not always a full path. This patch tweaks a couple of testcases to make the path part optional. gdb/testsuite: * lib/ada.exp (target_compile_ada_from_dir): New function. (gdb_compile_ada): Reimplement avoiding the use of project files. * gdb.ada/gnat_ada.gpr: Delete. * gdb.ada/cond_lang.exp: Adjust test to make path before filename optional. * gdb.ada/small_reg_param.exp: Likewise. Tested on x86_64-linux, with both in-tree and out-of-tree builds.

2015-12-22[lynxos] gdbserver hangs when killing inferior from GDBJoel Brobecker2-1/+27
With any program under GDBserver control on LynxOS, killing the program from the debugger (using the "kill" command) causes GDBserver to properly kill the inferior but GDBserver then hangs. This change of behavior occured after the following change was applied: commit f0ea042932e6922c90df3fd0001497d287b97677 Date: Mon Nov 30 16:05:27 2015 +0000 Subject: gdbserver: don't exit until GDB disconnects One of the changes introduced by the commit above is that process_serial_event no longer calls exit after handling the vKill packet. Instead, what happens is that we wait until captured_main finds that we no longer have any inferior to debug, at which point it throws_quit. This (normal) exception is then expected to propagate all the way to the exception handle in function "main", which calls exit. However, before the exception gets propagated, the cleanups are first executed, and one of the cleanups in question is detach_or_kill_for_exit_cleanup, which was put in place by captured_main. detach_or_kill_for_exit_cleanup is basically a wrapper around detach_or_kill_for_exit, which iterates over all inferiors, and kills them all. In our case, we have only one inferior, which we have already killed during the handling for the "vKill" packet. Unfortunately, we did not properly clean our internal data for that inferior up, and so detach_or_kill_for_exit thinks that we still have one inferior, and therefore tries to kill it. This results in lynx_kill being called, doing the following: lynx_ptrace (PTRACE_KILL, ptid, 0, 0, 0); lynx_wait (ptid, &status, 0); the_target->mourn (process); The hang is caused by the call to lynx_wait, which waits for an event from a process which does not exist... This patch fixes the issue by enhancing lynx_mourn to clean the threads and process list up. gdb/gdbserver/ChangeLog: * lynx-low.c (lynx_delete_thread_callback): New function. (lynx_mourn): Properly delete our process and all of its threads. Remove call to clear_inferiors.

For the record, the regression was introduced by: commit a67a9faef0e32886c83611cc7a0ba61e91123063 Date: Mon Nov 30 16:05:26 2015 +0000 Subject: gdbserver:prepare_access_memory: pick another thread This patch avoids the crash by checking the value of the callback first, before calling it. gdb/gdbserver/ChangeLog: * target.c (thread_search_callback): Add check that the thread_stopped target callback is not NULL before calling it.
2015-12-22[win32] cannot automatically find executable file [...] warning at GDB startupJoel Brobecker2-1/+7
The following change... commit 43499ea30db2a866412c86952c7e1d7b158d806f Date: Tue Nov 17 15:17:44 2015 +0000 Subject: [C++/mingw] windows-nat.c casts ... causes a small regression in GDB, where we get the following warning at startup: % gdb C:\[...]\gdb.exe: warning: cannot automatically find executable file or library to read symbols. Use "file" or "dll" command to load executable/libraries directly. GNU gdb (GDB) 7.10.50.20151218-cvs (with AdaCore local changes) [...] (gdb) The warning comes from _initialize_loadable which tries to dynamically load some symbols from kernel32.dll and psapi.dll, and in particular: hm = LoadLibrary ("psapi.dll"); if (hm) { GPA (hm, EnumProcessModules); GPA (hm, GetModuleInformation); GPA (hm, GetModuleFileNameEx); } The problem is that the new GPA macro assumes that the name of the variable we use to point to the function, and the name of its associated symbol are the same. This is mostly the case, except for GetModuleFileNameEx, where the name is provided by the GetModuleFileNameEx_name macro (defined differently depending on whether we are on cygwin or not). As a result, the dynamic resolution for GetModuleFileNameEx returns NULL, and we trip the following check which leads to the warning: if (!EnumProcessModules || !GetModuleInformation || !GetModuleFileNameEx) { [...] warning(_("[...]")); } This patch fixes the problem by calling GetProcAddress directly, rather than through the GPA macro, but in a way which hopefully avoids the C++ compilation warning that the previous patch was trying to get rid of. gdb/ChangeLog: * windows-nat.c (_initialize_loadable): Fix computing of GetModuleFileNameEx.

2015-12-18Add documentation to gdb_compileSimon Marchi2-0/+38
This patch adds some documentation to gdb_compile. It describes the various options that can influence compilation. Most of them are handled by DejaGnu, but are not really documented anywhere, so I think it's good to have a quick reference. Not all possible options are described, that would add way to much noise. I chose those that I think are relevant in the context of writing a test case. gdb/testsuite/ChangeLog: * lib/gdb.exp (gdb_compile): Add function doc.
2015-12-18Enable conditional breakpoints for targets that support software single step ↵Antoine Tremblay2-6/+6
in GDBServer This patch enables support for conditional breakpoints if the target supports software single step. This was disabled before as the implementations of software single step were too simple as discussed in https://sourceware.org/ml/gdb-patches/2015-04/msg01110.html. Since these issues are now fixed support can be added back. New tests passing : PASS: gdb.base/cond-eval-mode.exp: set breakpoint condition-evaluation target and related...

2015-12-18Support software single step on ARM in GDBServerAntoine Tremblay22-1361/+1924
This patch teaches GDBServer how to software single step on ARM linux by sharing code with GDB. The arm_get_next_pcs function in GDB is now shared with GDBServer. So that GDBServer can use the function to return the possible addresses of the next PC. A proper shared context was also needed so that we could share the code, this context is described in the arm_get_next_pcs structure. Testing : No regressions, tested on ubuntu 14.04 ARMv7 and x86.

2015-12-18Refactor arm_software_single_step to use regcacheAntoine Tremblay6-79/+212
This patch is in preparation for software single step support on ARM in GDBServer. It refactors arm_*_software_single_step and sub-functions to use regcache instead of frame to access registers so that the code can be shared more easily between GDB and GDBServer. Note also that since the intention is at some point to get rid of frame completely in that function, memory reads have also been replaced by read_memory_unsigned_integer rather than get_frame_memory_unsigned.

2015-12-18Replace breakpoint_reinsert_addr by get_next_pcs operation in GDBServerAntoine Tremblay11-13/+53
This patch in preparation for software single step support on ARM. It refactors breakpoint_reinsert_addr into get_next_pcs so that multiple location can be returned. When software single stepping there can be multiple possible next addresses because we're stepping over a conditional branch instruction, for example. The operation get_next_pcs handles that by returning a vector of all the possible next addresses. Software breakpoints are installed at each location returned.

2015-12-17Fix PR threads/19354: "info threads" error with multiple inferiorsPedro Alves5-34/+81
Note: this applies on top of: [PATCH] Remove support for LinuxThreads and vendor 2.4 kernels w/ backported NPTL https://sourceware.org/ml/gdb-patches/2015-12/msg00214.html We try to avoid using libthread_db.so to list threads in the inferior when debugging live processes, but the code that decides whether to use it decides incorrectly if you have more than one inferior, and the current inferior doesn't have execution yet. The result is visible as: (gdb) add-inferior Added inferior 2 (gdb) inferior 2 [Switching to inferior 2 [<null>] (<noexec>)] (gdb) info inferiors Num Description Executable 1 process 15397 /home/pedro/gdb/tests/threads * 2 <null> (gdb) info threads Cannot find new threads: generic error (gdb) Fix this by checking whether each inferior has execution rather than just the current inferior. By moving the core updating to linux-nat.c's update_thread_list implementation, this also ends up fixing the lwp-last-seen-running-on-core updating in the case we're debugging a program that uses raw clone rather than pthreads, as linux-thread-db.c isn't pushed in the target stack in that scenario.

Since we now rely on PTRACE_EVENT_CLONE being available (added in Linux 2.5.46), we're relying on NPTL. This commit removes the support for older LinuxThreads, as well as the workarounds for vendor 2.4 kernels with NPTL backported. - Rely on tkill being available. - Assume gdb doesn't get cancel signals. - Remove code that checks the LinuxThreads restart and cancel signals in the inferior. - Assume that __WALL is available. - Assume that non-leader threads report WIFEXITED. - Thus, no longer need to send signal 0 to check whether threads are still alive. - Update comments throughout. Tested on x86_64 Fedora 20, native and gdbserver. gdb/ChangeLog: * configure.ac: Remove tkill checks. * configure, config.in: Regenerate. * linux-nat.c: Remove HAVE_TKILL_SYSCALL check.
