Joel Brobecker	8a48ac9579	wrong dimension found in ada-lang.c:ada_array_bound_from_type 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.

Pedro Alves	f23981e991	Eliminate UNSUPPORTED_ERROR. 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.	13 years ago

Sergio Durigan Junior	08a6411c71	Sanitize access to gdbarch on the SDT probe API (and fix ARM bug) 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.

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.

Joel Brobecker	036e93dfda	Set language for Ada minimal symbols. This helps with the following issue: Given an Ada program defining a global variable: package Pck is Watch : Integer := 1974; end Pck; When printing the address of this variable, GDB also tries to print the associated symbol name: (gdb) p watch'address $1 = (access integer) 0x6139d8 <pck__watch> ^^ \|\| The problem is that GDB prints the variable's linkage name, instead of its natural name. This is because the language of the associated minimal symbol never really gets set. This patch adds handling for Ada symbols in symbol_find_demangled_name. After this patch, we now get: (gdb) p watch'address $1 = (access integer) 0x6139d8 <pck.watch> ^ \| gdb/ChangeLog: * symtab.c (symbol_find_demangled_name): Add handling of Ada symbols. gdb/testsuite/ChangeLog: * gdb.ada/int_deref.exp: Add test verifying that we print the decoded symbol name when printing the address of Ada symbols.	13 years ago

Joel Brobecker	94481b8c8f	nameless LOAD_DLL_DEBUG_EVENT causes ntdll.dll to be missing We observed on Windows 2012 that we were unable to unwind past exception handlers. For instance, with any Ada program raising an exception that does not get handled: % gnatmake -g a -bargs -shared % gdb a (gdb) start (gdb) catch exception unhandled Catchpoint 2: unhandled Ada exceptions (gdb) c Catchpoint 2, unhandled CONSTRAINT_ERROR at <__gnat_unhandled_exception> ( e=0x645ff820 <constraint_error>) at s-excdeb.adb:53 53 s-excdeb.adb: No such file or directory. At this point, we can already see that something went wrong, since the frame selected by the debugger corresponds to a runtime function rather than the function in the user code that caused the exception to be raised (in our case procedure A). This is further confirmed by the fact that we are unable to unwind all the way to procedure A: (gdb) bt #0 <__gnat_unhandled_exception> (e=0x645ff820 <constraint_error>) at s-excdeb.adb:53 #1 0x000000006444e9a3 in <__gnat_notify_unhandled_exception> (excep=0x284d2 +0) at a-exextr.adb:144 #2 0x00000000645f106a in __gnat_personality_imp () from C:\[...]\libgnat-7.3.dll #3 0x000000006144d1b7 in _GCC_specific_handler (ms_exc=0x242fab0, this_frame=0x242fe60, ms_orig_context=0x242f5c0, ms_disp=0x242ef70, gcc_per=0x645f0960 <__gnat_personality_imp>) at ../../../src/libgcc/unwind-seh.c:289 #4 0x00000000645f1211 in __gnat_personality_seh0 () from C:\[...]\libgnat-7.3.dll #5 0x000007fad3879f4d in ?? () Backtrace stopped: previous frame inner to this frame (corrupt stack?) It turns out that the unwinder has been doing its job flawlessly up until frame #5. The address in frame #5 is correct, but GDB is not able to associate it with any symbol or unwind record. And this is because this address is inside ntdll.dll, and when we received the LOAD_DLL_DEBUG_EVENT for that DLL, the system was not able to tell us the name of the library, thus causing us to silently ignoring the event. Because GDB does not know about ntdll.dll, it is unable to access the unwind information from it. And because the function at that address does not use a frame pointer, the unwinding becomes impossible. This patch helps recovering ntdll.dll at the end of the "run/attach" phase, simply by trying to locate that specific DLL again. In terms of our medium to long term planning, it seems to me that we should be able to simplify the code by ignoring LOAD_DLL_DEBUG_EVENT during the startup phase, and modify windows_ensure_ntdll_loaded to then detect and report all shared libraries after we've finished inferior creation. But for a change just before 7.7 branch creation, I thought it was safest to just handle ntdll.dll specifically. This is less intrusive, and ntdll is the only DLL affected by the problem I know so far. gdb/ChangeLog: * windows-nat.c (handle_load_dll): Add comments. (windows_ensure_ntdll_loaded): New function.

The patch deletes the frame_unwind_caller_pc_if_available wrapper function and instead lets errors propagate to frame_info (it's only user). As frame_unwind_pc now needs to be able to handle and cache two different error scenarios, the prev_pc.p variable is replaced with an enumeration. (FWIW, I looked into making gdbarch_unwind_pc or a variant return struct value's instead, but it results in lots of boxing and unboxing for no real gain -- e.g., the mips and arm implementations need to do computation on the unboxed PC value. Might as well throw an error on first attempt to get at invalid contents.) After the patch, we get: (gdb) info frame Stack level 2, frame at 0x0: rip = 0x323d4f168d in clone (../sysdeps/unix/sysv/linux/x86_64/clone.S:115); saved rip = <not saved> Outermost frame: outermost caller of frame at 0x7ffff7fcafc0 source language asm.

Tom Tromey	e1b06ae220	pack partial_symtab for space This improves the packing of struct partial_symtab. I noticed with pahole that were were a couple of holes. This consolidates the holes without, I think, affecting readability -- it just moves the "user" field a bit earlier in the struct. This change saves a small amount of memory. 2013-12-06 Tom Tromey <tromey@redhat.com> * psympriv.h (struct partial_symtab) <user>: Move earlier.	13 years ago
Tom Tromey	2b69941d0d	fix a couple of FIXMEs This fixes a couple of old "32x64" FIXME comments by using paddress with current_gdbarch rather than hex_string and a cast to long. 2013-12-06 Tom Tromey <tromey@redhat.com> * cli/cli-cmds.c (edit_command): Use paddress, not hex_string. (list_command): Likewise.	13 years ago
