2013-12-18Improve and fix catch-syscall.expSergio Durigan Junior3-98/+91
While fixing another bug, I found that the current gdb.base/catch-syscall.exp is kind of messy, could use some improvements, and is not correctly testing some things. I've made the following patch to address all the issues I found. On the organization side, it does a cleanup and removes unecessary imports of gdb_prompt, uses prepare_for_testing and clean_restart where needed, and fixes some comments. The testcase was also not correctly testing catching syscalls using only numbers, or catching many syscalls at once. I fixed that. The patch also uses a new method for obtaining the syscalls numbers: it relies on the C source file to get them, via <sys/syscall.h> and SYS_* macros. This makes the .exp file simpler because there is no need to include target conditionals there. I tested this on x86_64 Fedora 18. gdb/testsuite/ChangeLog: 2013-12-18 Sergio Durigan Junior <sergiodj@redhat.com> * gdb.base/catch-syscall.c: Include <sys/syscall.h>.

2013-12-17"tfind" across unavailable-stack frames.Pedro Alves8-50/+139
Like when stepping, the current stack frame location is expected to be printed as result of tfind command, if that results in moving to a different function. In tfind_1 we see: if (from_tty && (has_stack_frames () || traceframe_number >= 0)) { enum print_what print_what; /* NOTE: in imitation of the step command, try to determine whether we have made a transition from one function to another. If so, we'll print the "stack frame" (ie. the new function and it's arguments) -- otherwise we'll just show the new source line. */ if (frame_id_eq (old_frame_id, get_frame_id (get_current_frame ()))) print_what = SRC_LINE; else print_what = SRC_AND_LOC; print_stack_frame (get_selected_frame (NULL), 1, print_what, 1); do_displays (); } However, when we haven't collected any registers in the tracepoint (collect $regs), that doesn't actually work: (gdb) tstart (gdb) info tracepoints Num Type Disp Enb Address What 1 tracepoint keep y 0x080483b7 in func0 at ../.././../git/gdb/testsuite/gdb.trace/circ.c:28 collect testload installed on target 2 tracepoint keep y 0x080483bc in func1 at ../.././../git/gdb/testsuite/gdb.trace/circ.c:32 collect testload installed on target (gdb) c Continuing. Breakpoint 3, end () at ../.././../git/gdb/testsuite/gdb.trace/circ.c:72 72 } (gdb) tstop (gdb) tfind start Found trace frame 0, tracepoint 1 #0 func0 () at ../.././../git/gdb/testsuite/gdb.trace/circ.c:28 28 } (gdb) tfind Found trace frame 1, tracepoint 2 32 } (gdb) When we don't have info about the stack available (UNWIND_UNAVAILABLE), frames end up with outer_frame_id as frame ID. And in the scenario above, the issue is that both frames before and after the second tfind (the frames for func0 an func1) have the same id (outer_frame_id), so the frame_id_eq check returns false, even though the frames were of different functions. GDB knows that, because the PC is inferred from the tracepoint's address, even if no registers were collected. To fix this, this patch adds support for frame ids with a valid code address, but <unavailable> stack address, and then makes the unwinders use that instead of the catch-all outer_frame_id for such frames. The frame_id_eq check in tfind_1 then automatically does the right thing as expected. I tested with --directory=gdb.trace/ , before/after the patch, and compared the resulting gdb.logs, then adjusted the tests to expect the extra output that came out. Turns out that was only circ.exp, the original test that actually brought this issue to light.

This reverts commit 07293be44859c607a36c313e51bec2dcdcd3c243, as it causes an unintended change of behavior with GDB/MI's =library-loaded events: The host-name="<path>" part of the event is now showing the target-side path instead of the host-side path. This revert affects Darwin and AIX systems, however, where the BFD is either artificial or icomplete, leading to the outputt of "info shared" not containing the information we'd like. For instance, on Darwin, we would see: (top-gdb) info shared From To Syms Read Shared Object Library 0x00007fff8d060de4 0x00007fff8d09ce1f Yes (*) i386:x86-64 0x00007fff8af08b10 0x00007fff8b1c6f73 Yes (*) i386:x86-64 To compensate for that, we overwrite the filename of the associated bfd. gdb/ChangeLog: Revert the following commit: * solib.c (solib_map_sections): Remove code overwriting SO->SO_NAME with the bfd's filename. Make the following changes required after the revert above: * solib-aix.c (solib_aix_bfd_open): Set the filename of the returned bfd to a copy of the synthetic pathname. * solib-darwin.c (darwin_bfd_open): Set the filename of the returned bfd to a copy of PATHNAME.

2013-12-13nameless LOAD_DLL_DEBUG_EVENT causes ntdll.dll to be missingJoel Brobecker4-0/+107
This is the gdbserver-equivalent of the change made in GDB to handle the case, in x64 windows version 2012, where the kernel produces a LOAD_DLL_DEBUG_EVENT where the name of the associated DLL cannot be determined at that time, and thus has to be processed later. The visible symptom is that ntdll.dll is missing from the list of shared libraries known to be mapped by the inferior, with other side-effects such as failure to unwind through code provided by that DLL (such as exception handling routines). gdb/gdbserver/ChangeLog: * Makefile.in (safe-ctype.o, lbasename.o): New rules. * configure.srv: Add safe-ctype.o and lbasename.o to srv_tgtobj for all targets that use win32-low.c. * win32-low.c (win32_ensure_ntdll_loaded): New function. (do_initial_child_stuff): Add call to win32_ensure_ntdll_loaded.
2013-12-13Do the target-waiting within do_initial_child_stuff on Windows.Pedro Alves3-15/+66
This is a preparatory patch that achieves two goals: . Makes the initial event handling more similar to GDB's; . Opens the door for implementing post-inititial-handling operations. At the moment, this is only done on Windows, where the post-initial-handling is going to be needed (in the context of Windows 2012). And because we're close to creating the gdb 7.7 branch, making that change for all platforms is a little more risk that we'd like. So the change is currently implemented on Windows. gdb/gdbserver/ChangeLog: * target.c (mywait): Set OURSTATUS->KIND to TARGET_WAITKIND_STOPPED if equal to TARGET_WAITKIND_LOADED. * win32-low.c (cached_status): New static global. (win32_wait): Add declaration. (do_initial_child_stuff): Flush all initial pending debug events up to the initial breakpoint. (win32_wait): If CACHED_STATUS was set, return that instead of doing a real wait. Remove the code resuming the execution of the inferior after receiving a TARGET_WAITKIND_LOADED event during the initial phase. Also remove the code changing OURSTATUS->KIND from TARGET_WAITKIND_LOADED to TARGET_WAITKIND_STOPPED.

2013-12-13wrong dimension found in ada-lang.c:ada_array_bound_from_typeJoel Brobecker8-6/+181
This function has the following code: elt_type = type; for (i = n; i > 1; i--) elt_type = TYPE_TARGET_TYPE (type); For multi-dimension arrays, the code above tries to find the array type corresponding to the dimension we're trying to inspect. The problem is that, past the second dimension, the loop does nothing other than repeat the first iteration. There is a little thinko where it got the TYPE_TARGET_TYPE of TYPE instead of ELT_TYPE! To my surprise, I was unable to produce an Ada exemple that demonstrated the problem. That's because the examples I created all trigger a parallel ___XA type which we then use in place of the ELT_TYPE in order to determine the bounds - see the code that immediately follows our loop above: index_type_desc = ada_find_parallel_type (type, "___XA"); ada_fixup_array_indexes_type (index_type_desc); if (index_type_desc != NULL) [...] So, in order to avoid depending on an Ada example where the compiler can potentially decide one way or the other, I decided to use an artificial example, written in C. With ... int multi[1][2][3]; ... forcing the language to Ada, and trying to print the 'last, we get: (gdb) p multi'last(1) $1 = 0 (gdb) p multi'last(2) $2 = 1 (gdb) p multi'last(3) $3 = 1 <<<--- This should be 2! Additionally, I noticed that a couple of check_typedef's were missing. This patch adds them. And since the variable in question only gets used within an "else" block, I moved the variable declaration and use inside that block - making it clear what the scope of the variable is. gdb/ChangeLog: * ada-lang.c (ada_array_bound_from_type): Move the declaration and assignment of variable "elt_type" inside the else block where it is used. Add two missing check_typedef calls. Fix bug where we got TYPE's TYPE_TARGET_TYPE, where in fact we really wanted to get ELT_TYPE's TYPE_TARGET_TYPE. gdb/testsuite/ChangeLog: * gdb.ada/arraydim: New testcase.
