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.

2010-04-19gdb: objc-lang: check symbol name before accessing memoryMike Frysinger2-8/+15
The current ObjC logic will check both the symbol name and the target address space when trying to locate an appropriate selector. The problem is that first the target address space is checked before the symbol name. This may lead to a lot of unnecessary host<->target transactions when dealing with a non-OjbC target that does use function descriptors to describe functions as every symbol will have its FD read just to have the result thrown away with non-matching symbol names. It also may lead to problems when a non-FD symbol is found that points near the end of the address space as the target will throw up a memory_error(). One such example are symbols that are not functions, smaller than a FD, and are the last valid location. Obviously treating it as a larger data struct can cause memory overflows. So to speed things up and not screw over such targets, check the symbol name (which we already have locally) first before attempting to read the function's descriptor. This fixes breakpoints with Blackfin Linux FDPIC ELFs, and seems to cause no native regressions on my x86_64/Linux system. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-04-16gdb: fdpic/frv: fix shared library loadingMike Frysinger2-10/+33
The recent change to reload_shared_libraries() broke FDPIC shared libraries as the solib-frv.c code was implicitly relying on the initial order of calls (first solib_addr() and then solib_create_inferior_hook()). It was maintaining internal state via enable_break{1,2}_done to handle this. While I could tweak these values a bit more, the original code wasn't terribly bullet proof -- if during the initial debug you attempted to view shared libraries, the enable2_break() code would whine about the ldso internal debug addresses being unfetchable (and would actually attempt to read address 0x8 on the target). So I've dropped this implicit dependency on order (i.e. enable_break1_done) and updated the ldso poking code (i.e. enable_break2) to silently return when the internal debug address is still set to 0. It will remain this way until the ldso gets a chance to initialize at which point the code will act the same as before. While I have no way of testing the FRV, the Blackfin FDPIC code is using this same base in a 100% copy & paste method since we implemented FDPIC the same way as the FRV guys (I'll address this in the future). This fix was required in order to handle shared libraries with Blackfin FDPIC properly, and I see no reason why it wouldn't also work for FRV (since the uClibc ldso FDPIC code is the same too and that's really what this is poking).
