2016-05-02Fix detach.exp remote checkSimon Marchi2-5/+4
This test seems to work with both native-gdbserver and native-extended-gdbserver, so I removed the remote check. When running with native-gdbserver (a stub-like target), detach makes gdbserver stop and gdb disconnect. runto_main just spawns a brand new gdbserver. So it tests the exact same thing twice. It doesn't hurt though. With native-extended-gdbserver, the test is probably a bit more useful (and similar to native). It tests running/detaching twice using the same gdb/gdbserver instances, since with extended-remote, you can detach/attach/run all you want, unlike with remote. gdb/testsuite/ChangeLog: * gdb.base/detach.exp: Remove is_remote check.
2016-05-02Fix annota-input-while-running.exp remote checkSimon Marchi2-19/+12
The comment says that we can't use runto_main here becore it doesn't know how to handle annotation. Instead, the test puts a breakpoint at main and calls run by hand. Therefore, it can't work with stub targets, since they can't "run". The check should be then changed to check the use_gdb_stub variable instead of [is_remote target]. But as an alternative, we can just use runto_main and enable annotations after, since the "run to main" part is not really part of what we want to test. I also removed the "set test..." line that is unused. gdb/testsuite/ChangeLog: * gdb.base/annota-input-while-running.exp: Don't check for [is_remote target]. Enable annotations after running to main. Remove unused "set test..." line.

2016-04-28Fix write endianness/size problem for fast tracepoint enabled flagPar Olsson2-1/+14
I am sending this fix on behalf of Par Olsson, as a follow-up of this one: https://www.sourceware.org/ml/gdb-patches/2015-10/msg00196.html This problem is exposed when enabling/disabling fast tracepoints on big endian machines. The flag is defined as an int8_t, but is written from gdbserver as an integer (usually 32 bits). When the agent code reads it as an int8_t, it only considers the most significant byte, which is always 0. Also, we were writing 32 bits in an 8 bits field, so the write would overflow, but since the following bytes are padding (the next field is an uint64_t), it luckily didn't cause any issue on little endian systems. The fix was originally tested on ARM big endian systems, but I don't have access to such a system. However, thanks to Marcin's PowerPC fast tracepoint patches and gcc110 (big endian Power7) on the gcc compile farm, I was able to reproduce the problem, test the fix and write a test (the following patch). gdb/gdbserver/ChangeLog: YYYY-MM-DD Par Olsson <par.olsson@windriver.com> * tracepoint.c (write_inferior_int8): New function. (cmd_qtenable_disable): Write enable flag using write_inferior_int8.
2016-04-28ftrace tests: Use gdb_load_shlib result to lookup IPA in info sharedlibrarySimon Marchi8-14/+25
Some fast tracepoints tests make sure that the in-process agent library is properly loaded, by searching for the library name in "info sharedlibrary". Originally, it would search for the full path. Since patch "Make ftrace tests work with remote targets" [1], the "runtime" location of the IPA, in the standard output directory, is not the same as the original location, in the gdbserver build directory. Therefore, the patch changed the checks: gdb_test "info sharedlibrary" ".*${libipa}.*" "IPA loaded" to gdb_test "info sharedlibrary" ".*[file tail ${libipa}].*" "IPA loaded" so that only the "libinproctrace.so" part would be searched for. Antoine (in CC) pointed out that I missed some, so I have to update them. In the mean time, I noticed that I missed a few test failures: adding the SONAME to the IPA makes it possible for the test executable to erroneously pick up libinproctrace.so from /usr/lib if the test harness failed to put the libinproctrace.so we want to test in the right place. To mitigate that kind of error in the future, we can use the return value of gdb_load_shlib (the path of the "runtime" version of the library) and use that to search in the output of info sharedlibrary. When testing locally, gdb_load_shlib returns the full normalized path of the destination library, which the test executable should use e.g.: /path/to/gdb/testsuite/outputs/gdb.trace/thetest/libinproctrace.so My testing showed that it was the same path that gdb displayed in info sharedlibrary. If the test executable picks up another libinproctrace.so, the test will fail. When testing remotely, gdb_load_shlib/gdb_remote_download only returns us "libinproctrace.so", so the situation doesn't really change. If there is a rogue libinproctrace.so in /usr/lib on the target and we fail to download ours, it might cover up a test failure. But that situation is probably still better than the original one, where it wasn't possible to test remotely using the IPA at all.

2016-04-28Remove need_step_over from struct lwp_infoYao Qi2-20/+0
Hi, I happen to see that field need_step_over in struct lwp_info is only used to print a debug info. need_step_over is set in linux_wait_1 when breakpoint_here is true, however, we check breakpoint_here too in need_step_over_p and do the step over. I think we don't need field need_step_over, and check breakpoint_here directly in need_step_over_p. This field was added in this patch https://sourceware.org/ml/gdb-patches/2010-03/msg00605.html and the code wasn't changed much since then.

2016-04-27Make gdb_load_shlibs return the destination path of the librarySimon Marchi11-15/+38
This patch makes gdb_load_shlibs return the destination path of the copied library. To make the procedure implementation and interface more straightforward, it also changes it so that it accepts a single shared library path at the time. Therefore, calls that are passed multiple libraries: gdb_load_shlibs $lib1 $lib2 must be changed to separate calls: gdb_load_shlibs $lib1 gdb_load_shlibs $lib2 A subtle impact is the solib-search-path handling. In the former version, solib-search-path is set using the directory of the first passed lib (further calls overwrite the value). In the later version, the directory of the library passed to the last call to gdb_load_shlibs remnains. I don't think that's a problem in practice, since if we had tests that needed multiple different paths in solib-search-path, they wouldn't work in the first place.

2016-04-27c_value_print: Revert 'val' to a reference for TYPE_CODE_STRUCTMartin Galvan2-8/+14
Currently c_value_print will turn struct reference values into pointers before doing a set of RTTI checks. This was introduced as a fix to PR c++/15401. If there's RTTI the pointer will be adjusted and converted back to a reference. However, if there's no RTTI the value will still be treated as a pointer during the remainder of the function. This patch moves the conversion down so that it's always performed when needed. Notice this currently has not user-visible effects, so can be seen as a small code cleanup. However, it'll be necessary for the bug-fix for handling synthetic C++ references. It causes no testsuite regressions. gdb/ChangeLog: 2016-04-26 Martin Galvan <martin.galvan@tallertechnologies.com> * c-valprint.c (c_value_print): Always convert val back to reference type if we converted it to a pointer type.

2016-04-27Avoid non-C++-enabled babeltrace versionsAndreas Arnez3-0/+8
In some babeltrace versions before 1.2.0, the header file iterator.h declares the enum values `BT_SEEK_*' within the struct declaration of bt_iter_pos. The enum values are supposed to be globally-scoped, which works for C, but not for C++. Later babeltrace versions declare the enum outside the struct: https://lists.lttng.org/pipermail/lttng-dev/2013-September/021411.html Now that GDB is compiled with C++, the GDB build fails on a system with an affected babeltrace version: the compiler complains about a missing declaration of BT_SEEK_BEGIN in ctf.c.

The benefit of using the new interface is that it takes care of dynamic types and resolve them when needed. This fixes issues when printing structures with dynamic arrays from toplevel.

2016-04-26fort_dyn_array: Enable dynamic member types inside a structure.Bernhard Heckel8-6/+292
Fortran supports dynamic types for which bounds, size and location can vary during their lifetime. As a result of the dynamic behaviour, they have to be resolved at every query. This patch will resolve the type of a structure field when it is dynamic. 2016-04-26 Bernhard Heckel <bernhard.heckel@intel.com> 2016-04-26 Keven Boell <keven.boell@intel.com> Before: (gdb) print threev%ivla(1) Cannot access memory at address 0x3 (gdb) print threev%ivla(5) no such vector element After: (gdb) print threev%ivla(1) $9 = 1 (gdb) print threev%ivla(5) $10 = 42 gdb/Changelog: * NEWS: Add new supported features for fortran. * gdbtypes.c (remove_dyn_prop): New.

2016-04-26Always count the NULL entry in dynamic symbol tableH.J. Lu3-19/+24
There is an unused NULL entry at the head of dynamic symbol table which we must account for in our count even if the table is empty or unused since it is intended for the mandatory DT_SYMTAB tag (.dynsym section) in .dynamic section. * elf-bfd.h (elf_link_hash_table): Update comments for dynsymcount. * elflink.c (_bfd_elf_link_renumber_dynsyms): Always count for the unused NULL entry at the head of dynamic symbol table.

2016-04-25Resume the inferior with signal rather than stepping overYao Qi2-3/+21
When GDBserver steps over a breakpoint using software single step, it enqueues the signal, single step and deliver the signal in the next resume if step over is not needed. In this way, the program won't receive the signal if the conditional breakpoint is set a branch to self instruction, because the step over is always needed. This patch removes the restriction that don't deliver the signal to the inferior if we are trying to reinsert a breakpoint for software single step and change the decision on resume vs. step-over when the LWP has pending signals to deliver. gdb/gdbserver: 2016-04-25 Yao Qi <yao.qi@linaro.org> * linux-low.c (lwp_signal_can_be_delivered): Adjust. (need_step_over_p): Return zero if the LWP has pending signals can be delivered on software single step target.
