2011-07-01[mach-o] get rid of current_oso globalJoel Brobecker2-68/+75
This current_oso global was used to store the OSO's symbol table in order to relocate common symbols. But it is also making the assumption that all sections are going to be immediately relocated as macho_add_oso_symfile does: - Initialize the current_oso - Use it through symbol_file_add_from_bfd - Reset the current_oso (to all fields NULL) What actually happens is that the .debug_frame section gets read lazily, and thus relocated at a later time. This relocation causes current_oso.symbol_table to be initialized (see macho_symfile_relocate) again. And this eventually causes to trip the... gdb_assert (current_oso.symbol_table == NULL); ...assertion to fail because the symbol_table was never free'ed. To be complete, this happens because macho_symfile_relocate was called outside of macho_add_oso_symfile's control, where the set-global/use/unset-global dance happens. But it looks like keeping this global around is not necessary, as this symbol table is only used to relocate the common symbols. We can do that prior to relocating the rest of the symbols. gdb/ChangeLog: * machoread.c (struct macho_oso_data): Delete. (current_oso): Delete. (macho_relocate_common_syms): New function, mostly extracted out of (macho_add_oso_symfile): Call macho_relocate_common_syms. Remove code that sets and unset current_oso.

2011-07-01[Darwin] Do not crash (failed assertion) after PT_KILL ptrace errorJoel Brobecker2-1/+25
It might not be a debugger bug that caused the PT_KILL ptrace operation to fail. So emit a warning instead, and try to continue. This patch also tries to handle the case where ptrace return -1, but left errno set to zero. According to the ptrace man page, it is possible for some ptrace operations to return -1 in non-error situations, and to detect those situations, it explains that errno should be set prior to calling ptrace, and then checked again after. gdb/ChangeLog: * darwin-nat.c (darwin_ptrace): Add documentation. Set errno to zero before calling ptrace. If ptrace returns -1 and errno is zero, then change then return zero. (darwin_kill_inferior): Issue a warning instead of triggering a failed assertion when the PT_KILL ptrace operations returned nonzero.
2011-07-01Darwin/detach: Do not resume inferior after ptrace detachJoel Brobecker2-1/+10
When trying to detach from an inferior that we start from the debugger, GDB prints the following warning: (gdb) detach Detaching from program: /[...]/foo, process 74593 warning: Mach error at "/[...]/darwin-nat.c:445" in function "darwin_resume_inferior": (os/kern) failure (0x5) The warning comes from the following code in darwin_detach: darwin_resume_inferior (inf); This is because the process has already been resumed by the PT_DETACH ptrace operation that has just been performed. On the other hand, when trying to detach from an inferior that was started outside of debugger control (thus after having attached the debugger to that inferior), things go smoothly. That's because we don't use ptrace to control the process in that case, and so the resume is perfectly justified. This patch makes sure that we resume the inferior during the detach only when we're NOT using ptrace. gdb/ChangeLog: * darwin-nat.c (darwin_detach): Call darwin_resume_inferior only when inf->private->no_ptrace.

2011-07-01crash when printing type of tagged typeJoel Brobecker2-2/+16
If the debugging info is incorrect or incomplete, printing the type description of a variable that's a variant tagged type can trigger a crash. The crash comes from us trying print a NULL string which was supposed to be the parent type name. We observed this behavior on bareboard targets where a-tags is not always linked in, as is the case for native platforms, for instance. Coupled with -feliminate-unused-debug-types, this leads to GDB being unable to find type ada__tags__type_specific_data, without which printing the type description above cannot be done acurately. There is an easy workaround for this limitation, which is to compile at least 1 unit with -fno-eliminate-unused-debug-types, but GDB should also be made resilient to this situation. gdb/ChangeLog: * ada-typeprint.c (print_record_type): If unable to decode the name of the parent type, use the encoded name.
2011-07-01Fix printing address of packed arrayJoel Brobecker5-15/+18
When trying to print the address of a non-packed array, GDB correctly prints the type name and address: (gdb) print &var $2 = (access pa.var) 0xbffff1d8 However, it is behaving differently when dealing with a packed array: (gdb) p &var (access array (4 .. 8) of boolean <packed: 1-bit elements>) (4 => false, false, false, true, false) The type description isn't all that bad, but GDB shouldn't be printing the array value! This patch fixes the `print` and `ptype` command on packed and non-packed array. It also fixes a gdb.ada test to match with the new ouput. gdb/ChangeLog (Jean-Charles Delay): * ada-typeprint.c (ada_print_type): Fix both PAD type and pointer to constrained packed array type output. * ada-valprint.c (ada_val_print_1): Fix pointer to constrained packed array output. gdb/testsuite/ChangeLog (Jean-Charles Delay): * gdb.ada/packed_array.exp: Fix expected outout.
2011-07-01Fix ada array bounds displayJoel Brobecker4-41/+45
Array bounds were not correctly displayed when the SHOW parameter of print_type functions is set to -1. This shows up in the following type of situation, where we have a declaration as follow: Anon_Array_Int_Obj : array (1..10) of Integer := (others => 8); In GDB/MI mode, trying to print the type info for our array object yields: (gdb) -var-create ai 0 Anon_Array_Int_Obj (gdb) -var-info-type ai ^done,type="array (...) of integer" The actual bounds are missing. Contrast this with what happens when in GDB/CLI mode: (gdb) ptype Anon_Array_Int_Obj type = array (1 .. 10) of integer This patch fixes array type printing accordingly. And as it turns out, it also improves the output for one of the tests already present, so it shows that it's not just the GDB/MI mode that's affected. gdb/ChangeLog (Jean-Charles Delay): * ada-typeprint.c (print_array_type): removed if condition on show being negative for bounds printing. gdb/testsuite/ChangeLog (Jean-Charles Delay): * gdb.ada/packed_array.exp: fixed expected output.
2011-07-01treat identical enum types as the same typeJoel Brobecker7-0/+242
This is to avoid an unnecessary multiple-choice menu for an expression involving an enumeral declared in two types, when the second type is an identical copy of the first type. This happens in the following situation: type Color is (Black, Red, Green, Blue, White); type RGB_Color is new Color range Red .. Blue; In that case, an implict type is created, and is used as the base type for type RGB_Color. This base type is a copy of type Color. We've added some extensive comments explaining the situation and our approach further. gdb/ChangeLog: * ada-lang.c (ada_identical_enum_types_p): New function. (symbols_are_identical_enums): New function. (remove_extra_symbols): Do nothing if NSYMS < 2. Use symbols_are_identical_enums. gdb/testsuite/ChangeLog: * gdb.ada/same_enum: New testcase.
2011-07-01missing type description for typedef to pointer valueJoel Brobecker7-1/+114

2011-07-01variables whose type is a typedef to an array pointerJoel Brobecker4-7/+20
If we declare a type as being an access to array type, and then declare a variable of that type, for instance: type Some_Array is array [...]; type Array_Access is access all Some_Array; Table : Array_Access := [...]; The variable "Table" may be defined in the debugging information as being a typedef to the array pointer type. In the past, it was defined directly as the array pointer type, but this has been changed to make sure that the typedef type gets used. If the typedef type wasn't used, it would allow the compiler to stop emitting that typedef type when compiling with -feliminate-unused-debug-types. The removal of this typedef would be a problem, because GDB relies on the typedef to create symbols for pointer types, and without it, we would no longer be able to do "ptype array_access". This patch helps prevent incorrect output or even crashes when that extra typedef layer is used. The testing is already mostly covered by arrayptr.exp, but I still added a 'ptype' test, just for good measure. gdb/ChangeLog: (Eric Botcazou) * ada-lang.c (thin_descriptor_type): Deal with typedefs. (decode_constrained_packed_array): Likewise. (ada_evaluate_subexp) <TERNOP_SLICE>: Likewise. gdb/testsuite/ChangeLog (Joel Brobecker): * gdb.ada/arrayptr.exp: Add ptype test.

2011-07-01handle character-based enumeration typedefsJoel Brobecker7-1/+114
Consider the following type: type Char_Enum_Type is ('A', 'B', 'C', 'D'); If the compiler generates a Char_Enum_Type typedef in the debugging information, the debugger fails in the following case: (gdb) p Char_Enum_Type'('B') $1 = 66 For our type, the underlying value of 'B' is actually 1, not 66 (ASCII 'B'). We are failing this case because we were not handling typedef to enum types before.
