2013-12-17Convert the unavailable vector to be bit, not byte, based.Andrew Burgess7-22/+625
https://sourceware.org/ml/gdb-patches/2013-12/msg00144.html The vector of unavailable parts of a value is currently byte based. Given that we can model a value down to the bit level, we can potentially loose information with the current implementation. After this patch we model the unavailable information in bits. gdb/ChangeLog * dwarf2loc.c (read_pieced_value): Mark bits, not bytes unavailable, use correct bit length. * value.c (struct value): Extend comment on unavailable to indicate that it is bit based.

2013-12-15Revert "Do not overwrite so_list's so_name in solib_map_sections"Joel Brobecker4-0/+43
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.

2013-12-12Eliminate UNSUPPORTED_ERROR.Pedro Alves5-24/+32
I have a case that could use an exception for "unsupported feature". I found UNSUPPORTED_ERROR, but looking deeper, I think as is, reusing it for other things would be fragile. E.g., if the Python script sourced by source_script_from_stream triggers any other missing functionality that would result in UNSUPPORTED_ERROR being propagated out to source_script_from_stream, that would confuse the error for Python not being built into GDB. This patch thus redoes things a little. Instead of using an exception for the "No Python" scenario, check whether Python is configured in before actually trying to source the file. It adds a new function instead of using #ifdef HAVE_PYTHON directly, as that is better at avoiding bitrot, as both Python and !Python paths are visible to the compiler this way. Tested on Fedora 17, with and without Python. gdb/ 2013-12-12 Pedro Alves <palves@redhat.com> * cli/cli-cmds.c (source_script_from_stream) Use have_python instead of catching UNSUPPORTED_ERROR. * exceptions.h (UNSUPPORTED_ERROR): Delete. * python/python.c (source_python_script) [!HAVE_PYTHON]: Internal error if called. * python/python.h (have_python): New static inline function.

2013-12-10Sanitize access to gdbarch on the SDT probe API (and fix ARM bug)Sergio Durigan Junior6-29/+71
This patch sanitizes the access to gdbarch made by various functions of the SDT probe API. Before this patch, gdbarch was being accessed via the probe's objfile; however, this proved to cause a bug on 32-bit ARM targets because during the parsing of the probe's arguments the code needed to access some pseudo-registers of the architecture, and this information is not fully correct on the objfile's gdbarch. Basically, the approach taken was to instead pass the current/selected frame to the parsing and evaluation functions, so that they can extract the gdbarch directly from the frame. It solved the ARM bug reported above, and also contributed to make the API cleaner. Tested on x86_64 and 32-bit ARM. 2013-12-11 Sergio Durigan Junior <sergiodj@redhat.com> * break-catch-throw.c (fetch_probe_arguments): Pass selected frame to get_probe_argument_count and evaluate_probe_argument. * probe.c (get_probe_argument_count): Adjust declaration to accept frame.

2013-12-10Use target_read_code in skip_prologue (i386)Yao Qi4-34/+106
GDB is able to cache memory accesses requested in target_read_code, so target_read_code is more efficient than general target_read_memory. This patch uses target_read_code and its variants to read target memory in the functions related to i386_skip_prologue. It improves the performance when doing 'b foo' (foo is a function) in remote debugging. Nowadays, when we set a breakpoint on function f1, GDB will fetch the code in f1 to determine the start of the function body (say skip the prologue), it requests read from target many times. With this patch applied, the number of RSP 'm' packets are reduced. gdb: 2013-12-10 Yao Qi <yao@codesourcery.com> * corefile.c (read_code): New function. (read_code_integer): New function.
