2010-04-20Implement thread support with core files on alpha-tru64Joel Brobecker2-10/+29
Thread support currently does not work with core files. Note that, in order to thread support to work on tru64, one need to allow GDB to write in the core file (this is because the thread debug library needs to write). An obvious visible symptom of the problem is that "info threads" does not list the various threads: (gdb) info threads * 1 <main task> 0x000003ff805c0918 in __nxm_thread_kill () from /usr/shlib/libpthread.so One other noticeable consequence is that GDB generates some warnings when using "info tasks": (gdb) info tasks warning: Could not find thread id from THREAD = 0x3ffc01b6000 warning: Could not find thread id from THREAD = 0x20000e2b4c0 ID TID P-ID Pri State Name * 1 140051000 0 30 Runnable main_task * 2 14005c000 1 30 Accept or Select Term my_t (notice also how both tasks are marked as being the active task, which cannot be true). The problem is that the dec-thread module has not updated its thread list after the core file got loaded. In fact, the list only gets resync'ed at the end of each target-wait. The solution was to implement the find_new_threads target_ops method. gdb/ChangeLog: Implement thread support with core files on alpha-tru64. * dec-thread.c (dec_thread_find_new_threads): New function, extracted from resync_thread_list.

2010-04-20[AVR] inferior call of subprogram with pointer as argumentJoel Brobecker2-2/+29
On AVR, the gdb view of an address is different from the machine view of the same address. We need to use special machinery implemented by value_pointer to take the pointer of a value. For instance, considering the following function... procedure Trace (Unit : T; Message : String); ... where T is an access Integer (a pointer to an integer), call to this function currently triggers the following warnings: (gdb) call debug.trace (me, "You") warning: Value does not fit in 16 bits. warning: Value does not fit in 16 bits. Tracing message: You It could have been worse if Trace actually tried to dereference the Unit argument... gdb/ChangeLog (from Tristan Gingold): * ada-lang.c (value_pointer): New function. (make_array_descriptor): Call value_pointer to convert addresses to pointers. Tested on avr and x86_64-linux.
2010-04-20[AIX] Memory error while checking if pointer is descriptor.Joel Brobecker2-3/+24
A long time ago (Oct 2009), I noticed a problem on AIX, where something failed with an error while the debugger was checking whether an address was a descriptor or not. Unfortunately, like an idiot, I forgot to write notes about the scenario where the problem occured - I am usually pretty meticulous about that because my memory of these things is really bad. I hope you'll forgive me for not providing a solid testcase - if it's any consolation, I've searched for a long time before giving up :-(. Based on the testsuite reports that I have, I think that this happened while inserting a breakpoint, as follow: (gdb) break x Cannot access memory at address 0x200093b4 What happened is that rs6000_convert_from_func_ptr_addr tried to read the memory at the given address, and fail because of an exception. It seems pretty clear that, if the address was in fact a descriptor, GDB would have been able to read the target memory region. So this patch protects the memory-read against exceptions, and treats such exceptions as an indication that our address is not a descriptor. gdb/ChangeLog: * rs6000-aix-tdep.c: #include exceptions.h. (rs6000_convert_from_func_ptr_addr): If an exception is thrown while reading the memory at ADDR, then ADDR cannot be a function descriptor.
2010-04-20"unsupported language" error in info types when using Ada.Joel Brobecker7-1/+92
This implements a rudimentary version of the la_print_typedef method for Ada. Ada usually does not use typedefs, but there is one exception: pointers to unconstrained arrays. Without this patch, we sometimes get an error in the "info types" output: (gdb) info types new_integer_type All types matching regular expression "new_integer_type": File foo.adb: Language not supported. For now, we treat the typedef as if it did not exist - using the underlying type instead. This is the right thing to do for most cases, the only exception being access to array types. Since we already have a general issue in handling these pointers (we confuse them with fat pointers), we will enhance ada_print_typedef to handle these pointers at the same time we address the general issue. gdb/ChangeLog: * ada-typeprint.c (ada_print_typedef): New function. * ada-lang.h (ada_print_typedef): Add declaration. * ada-lang.c (ada_language_defn): set la_print_typdef field to ada_print_typedef. gdb/testsuite/ChangeLog: * info_types.c, info_types.exp: New files. Tested on x86_64-linux.
2010-04-20Unused function in procfs.c on alpha-tru64.Joel Brobecker2-1/+7

2010-04-20procfs.c: iterate_over_mappings callback has wrong profile.Joel Brobecker2-4/+28
The function proc_find_memory_regions calls iterate_over_mappings as follow: > return iterate_over_mappings (pi, func, data, > find_memory_regions_callback); The problem is that both func and find_memory_regions_callback do not match the profile expected by iterate_over_mappings: > iterate_over_mappings (procinfo *pi, int (*child_func) (), void *data, > int (*func) (struct prmap *map, > int (*child_func) (), > void *data)) We cannot change proc_find_memory_regions such that FUNC is a pointer to a function that takes no argument (in place of the 6 that it has). This is because proc_find_memory_regions is used as a target_ops method. However, it turns out that changing iterate_over_mappings to conform to the profile imposed by the target_ops vector is possible without much effort. gdb/ChangeLog: * procfs.c (iterate_over_mappings_cb_ftype): New typedef. (iterate_over_mappings): Adjust function profile. Add declaration. (insert_dbx_link_bpt_in_region, info_mappings_callback): Adjust accordingly.
2010-04-20procfs.c: Move solib_mappings_callback up to avoid compiler warning.Joel Brobecker2-51/+52
There are currently 2 issues with the placement of this routine: - It's defined after it is being used (causing an implicit declaration); - It looks like it's being defined all the time, whereas it is used only on mips-irix (AFAICT) - shouldn't have this triggered a warning on sparc-solaris, for instance??? In any case, this patch moves this function up, inside the right region, just before the function where it is actually used. gdb/ChangeLog: * procfs.c (solib_mappings_callback): Move function up to avoid a compiler warning.
2010-04-20procfs.c: Move find_signalled_thread and find_stop_signal.Joel Brobecker2-22/+27
These two functions are only used from procfs_make_note_section, which itself is only defined if: #if defined (UNIXWARE) || defined (PIOCOPENLWP) || defined (PCAGENT) So these two functions are unused on mips-irix, and they get flagged by -Wunused-function. This patch simply moves these functions closer to the function that uses them, which also has the effect of putting them inside the same #if block as procfs_make_note_section. Thus they are defined only when used. gdb/ChangeLog: * procfs.c (find_signalled_thread, find_stop_signal): Move these functions down to define them only when used.
2010-04-20Wrong value printed by info locals for dynamic object.Joel Brobecker10-9/+151
The problem is printing the wrong value for dynamic local variables when using the "info locals" command. Consider the following code: procedure Print (I1 : Positive; I2 : Positive) is type My_String is array (I1 .. I2) of Character; I : My_String := (others => 'A'); S : String (1 .. I2 + 3) := (others => ' '); begin S (I1 .. I2) := String (I); -- BREAK Put_Line (S); end Print; After the debugger stopped at BREAK, we try printing all local variables. Here is what we get: (gdb) info locals i = "["00"]["00"]" s = "["00"]["00"]["00"]["00"]["00"]["00"]["00"]["00"]" Curiously, printing their value using the "print" command works: (gdb) print i $1 = "AA" (gdb) print s $2 = " " We traced the problem to trying to get the contents of a variable (call to value_contents) before "fix'ing" it. For those not familiar with the Ada language support, "fixing" a value consists of swapping the value's dynamic type with a static version that is appropriate for our actual value. As a result, the dynamic type was used to determine the value size, which is zero, and thus the value contents was empty. gdb/ChangeLog: * valprint.c (common_val_print): Fix the value before extracting its contents. * ada-lang.c (ada_to_fixed_value): Make this function extern. * ada-lang.h (ada_to_fixed_value): New function declaration. * ada-valprint.c (ada_value_print): Use ada_to_fixed_value to avoid code duplication and fix a bug in the handling of fixed types contents. gdb/testsuite/ChangeLog: * gdb.ada/dyn_loc: New testcase.
