* Fix gdb.trace/{actions,infotrace,while-stepping}.exp with extended-remotePedro Alves2015-04-084-3/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent actions.exp change to check gdb_run_cmd succeeded caught further problems. The test now fails like this with --target_board=native-extended-gdbserver: FAIL: gdb.trace/actions.exp: Can't run to main gdb.log shows: (gdb) run Starting program: /home/pedro/gdb/mygit/build/gdb/testsuite/gdb.trace/actions Running the default executable on the remote target failed; try "set remote exec-file"? (gdb) FAIL: gdb.trace/actions.exp: Can't run to main The problem is that a gdb_load call is missing. Grepping around for similar problems in other tests, I found that infotrace.exp and while-stepping.exp should be likewise affected. And indeed this is what we get today: FAIL: gdb.trace/infotrace.exp: tstart FAIL: gdb.trace/infotrace.exp: continue to end (the program is no longer running) FAIL: gdb.trace/infotrace.exp: tstop FAIL: gdb.trace/infotrace.exp: 2.6: info tracepoints (trace buffer usage) FAIL: gdb.trace/while-stepping.exp: tstart FAIL: gdb.trace/while-stepping.exp: tstop FAIL: gdb.trace/while-stepping.exp: tfile: info tracepoints FAIL: gdb.trace/while-stepping.exp: ctf: info tracepoints while-stepping.exp even has the same race bug actions.exp had. After this, {actions,infotrace,while-stepping}.exp all pass cleanly with the native-extended-gdbserver board. gdb/testsuite/ChangeLog: 2015-04-08 Pedro Alves <palves@redhat.com> * gdb.trace/actions.exp: Use gdb_load before gdb_run_cmd. * gdb.trace/infotrace.exp: Use gdb_load before gdb_run_cmd. Use gdb_breakpoint instead of gdb_test that doesn't expect anything. Return early if running to main fails. * gdb.trace/while-stepping.exp: Likewise.

* gdb.base/interrupt.exp: Use send_inferior/$inferior_spawn_idPedro Alves2015-04-072-19/+43
| | | | | | | | | | | | | The gdb.base/interrupt.exp test is important for testing system call restarting, but because it depends on inferior I/O, it ends up skipped against gdbserver. This patch adjusts the test to use send_inferior and $inferior_spawn_id so it works against GDBserver. gdb/testsuite/ChangeLog: 2015-04-07 Pedro Alves <palves@redhat.com> * gdb.base/interrupt.exp: Don't skip if $inferior_spawn_id != $gdb_spawn_id. Use send_inferior and $inferior_spawn_id to interact with inferior program.
* testsuite: Introduce $inferior_spawn_idPedro Alves2015-04-073-4/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some important tests, like gdb.base/interrupt.exp end up skipped against gdbserver, because they depend on inferior I/O, which gdbserver doesn't do. This patch adds a mechanism that makes it possible to make them work. It adds a new "inferior_spawn_id" global that is the spawn ID used for I/O interaction with the inferior. By default, for native targets, or remote targets that can do I/O through GDB (semi-hosting) this will be the same as the gdb/host spawn ID. Otherwise, the board may set this to some other spawn ID. When debugging with GDBserver, this will be set to GDBserver's spawn ID. Then tests can use send_inferior instead of send_gdb to send input to the inferior, and use expect's "-i" switch to select which spawn ID to use for matching input/output. That is, something like this will now work: send_inferior "echo me\n" gdb_test_multiple "continue" "test msg" { -i "$inferior_spawn_id" -re "echo me\r\necho\r\n" { ... } } Or even: gdb_test_multiple "continue" "test msg" { -i "$inferior_spawn_id" -re "hello world" { ... } -i "$gdb_spawn_id" -re "error.*$gdb_prompt $" { ... } } Of course, by default, gdb_test_multiple still matches with $gdb_spawn_id. gdb/testsuite/ChangeLog: 2015-04-07 Pedro Alves <palves@redhat.com> * lib/gdb.exp (inferior_spawn_id): New global. (gdb_test_multiple): Handle "-i". Reset the spawn id to GDB's spawn id after processing the user code. (default_gdb_start): Set inferior_spawn_id.

* testsuite: Don't use expect_background to reap gdbserverPedro Alves2015-04-073-27/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | I adjusted a test to do 'expect -i $server_spawn_id -re ...', and saw really strange behavior. Whether that expect would work, depended on whether GDB would also send output and the same expect matched it too (on $gdb_spawn_id). I was perplexed until I noticed that gdbserver_spawn spawns gdbserver and then uses expect_background to reap gdbserver. That expect_background conflicts/races with any "expect -i $server_spawn_id" done anywhere else in parallel... In order to make it possible for tests to read inferior I/O out of $server_spawn_id, we to get rid of that expect_background. This patch makes us instead reap gdbserver's spawn id when GDB exits. If GDB is still around, this gives a chance for gdbserver to exit cleanly. The current code in gdb_finish uses "kill", but that doesn't work with extended-remote (gdbserver doesn't exit). We now use "monitor exit" instead which works in both remote and extended-remote modes. gdb/testsuite/ChangeLog: 2015-04-07 Pedro Alves <palves@redhat.com> * lib/gdb.exp (gdb_finish): Delete persistent gdbserver handling. * lib/gdbserver-support.exp (gdbserver_start): Make $server_spawn_id global. (gdbserver_start): Don't wait for gdbserver's spawn id with expect_background. (close_gdbserver): New procedure. (gdb_exit): Rename the default version and reimplement.
* gdb_test_multiple: Fix user code argument processingPedro Alves2015-04-072-1/+6
| | | | | | | | | | | | | | | | | | | | While teaching gdb_test_multiple to forward "-i" to gdb_expect, I found that with: gdb_test_multiple (...) { -i $some_variable -re "..." {} } $some_variable was not getting expanded in the gdb_test_multiple caller's scope. This is a bug inside gdb_test_multiple. When processing an argument in passed in user code, it was appending the original argument literally, instead of appending the uplist'ed argument. gdb/testsuite/ChangeLog: 2015-04-07 Pedro Alves <palves@redhat.com> * lib/gdb.exp (gdb_test_multiple): When processing an argument, append the substituted item, not the original item.

* gdb.base/interrupt.exp: Fix racePedro Alves2015-04-072-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Working on splitting gdb and inferior output handling in this test, I noticed a race that happens to be masked out today. The test sends "a\n" to the inferior, and then inferior echoes back "a\n". If expect manages to read only the first "a\r\n" into its buffer, then this matches: -re "^a\r\n(|a\r\n)$" { and leaves the second "a\r\n" in output. Then the next test that processes inferior I/O sends "data\n", and expects: -re "^(\r\n|)data\r\n(|data\r\n)$" which fails given the anchor and given "a\r\n" is still in the buffer. This is masked today because the test relies on inferior I/O being done on GDB's terminal, and there are tested GDB commands in between, which consume the "a\r\n" that was left in the output. We don't support SunOS4 anymore, so just remove the workaround. gdb/testsuite/ChangeLog 2015-04-07 Pedro Alves <palves@redhat.com> * gdb.base/interrupt.exp: Don't handle the case of the inferior output appearing once only.

* update thread list, delete exited threadsPedro Alves2015-04-076-10/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On GNU/Linux, if the running kernel supports clone events, then linux-thread-db.c defers thread listing to the target beneath: static void thread_db_update_thread_list (struct target_ops *ops) { ... if (target_has_execution && !thread_db_use_events ()) ops->beneath->to_update_thread_list (ops->beneath); else thread_db_update_thread_list_td_ta_thr_iter (ops); ... } However, when live debugging, the target beneath, linux-nat.c, does not implement the to_update_thread_list method. The result is that if a thread is marked exited (because it can't be deleted right now, e.g., it was the selected thread), then it won't ever be deleted, until the process exits or is killed/detached. A similar thing happens with the remote.c target. Because its target_update_thread_list implementation skips exited threads when it walks the current thread list looking for threads that no longer exits on the target side, using ALL_NON_EXITED_THREADS_SAFE, stale exited threads are never deleted. This is not a big deal -- I can't think of any way this might be user visible, other than gdb's memory growing a tiny bit whenever a thread gets stuck in exited state. Still, might as well clean things up properly. All other targets use prune_threads, so are unaffected. The fix adds a ALL_THREADS_SAFE macro, that like ALL_NON_EXITED_THREADS_SAFE, walks the thread list and allows deleting the iterated thread, and uses that in places that are walking the thread list in order to delete threads. Actually, after converting linux-nat.c and remote.c to use this, we find the only other user of ALL_NON_EXITED_THREADS_SAFE is also walking the list to delete threads. So we convert that too, and end up deleting ALL_NON_EXITED_THREADS_SAFE. Tested on x86_64 Fedora 20, native and gdbserver. gdb/ChangeLog 2015-04-07 Pedro Alves <palves@redhat.com> * gdbthread.h (ALL_NON_EXITED_THREADS_SAFE): Rename to ...

* Fallback to stub-termcap.c on all hostsPedro Alves2015-04-064-13/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently building gdb is impossible without an installed termcap or curses library. But, GDB already has a very minimal termcap in the tree to handle this situation for Windows -- gdb/stub-termcap.c. This patch makes that the fallback for all hosts. Testing this on GNU/Linux (by simply hacking away the termcap/curses detection in gdb/configure.ac), we trip on: ../readline/libreadline.a(terminal.o): In function `_rl_init_terminal_io': /home/pedro/gdb/mygit/src/readline/terminal.c:527: undefined reference to `PC' /home/pedro/gdb/mygit/src/readline/terminal.c:528: undefined reference to `BC' /home/pedro/gdb/mygit/src/readline/terminal.c:529: undefined reference to `UP' /home/pedro/gdb/mygit/src/readline/terminal.c:538: undefined reference to `PC' /home/pedro/gdb/mygit/src/readline/terminal.c:539: undefined reference to `BC' /home/pedro/gdb/mygit/src/readline/terminal.c:540: undefined reference to `UP' These are globals that are normally defined by termcap (or ncurses' termcap emulation). Now, we could just define replacements in stub-termcap.c, but readline/terminal.c (at least the copy in our tree) has this: #if !defined (__linux__) && !defined (NCURSES_VERSION) # if defined (__EMX__) || defined (NEED_EXTERN_PC) extern # endif /* __EMX__ || NEED_EXTERN_PC */ char PC, *BC, *UP; #endif /* !__linux__ && !NCURSES_VERSION */ which can result in readline defining the globals too. That will usually work out in C, given that "-fcommon" is usually the default for C compilers, but that won't work for C++, or C with -fno-common (link fails with "multiple definition" errors)... Mirroring those #ifdef conditions in the stub termcap screams "brittle" to me -- I can see them changing in latter readline versions. Work around that by simply using __attribute__((weak)). Windows/PE/COFF's do support weak, but not on gcc 3.4 based toolchains (4.8.x does work). Given the file never needed the variables while it was Windows-only, just continue not defining them there. All other supported hosts should support this. gdb/ChangeLog: 2015-04-06 Pedro Alves <palves@redhat.com> Bernd Edlinger <bernd.edlinger@hotmail.de> * configure.ac: Remove the mingw32-specific stub-termcap.o fallback, and instead fallback to the stub termcap on all hosts. * configure: Regenerate. * stub-termcap.c [!__MINGW32__] (PC, BC, UP): Define as weak symbols.

* sim: moxie: fix running after nrun conversionMike Frysinger2015-04-057-25/+102
| | | | | | | | The nrun conversion was slightly incorrect in how it stopped when an exception occurred. We still set cpu.asregs.exception, but nothing was checking it anymore. Convert all of that to sim_engine_halt. To keep things from regressing again, add a basic testsuite too.
