Conditional Z1 breakpoint hangs GDBserver.

While trying to fix hbreak2.exp against GDBserver I noticed this...

 Sending packet: $Z1,40058f,1;X3,220127#9b...

The issue is that nothing advances the packet pointer if
add_breakpoint_condition either fails to parse the agent expression,
or fails to find the breakpoint, resulting in an infinite loop in
process_point_options.  The latter case should really be fixed by
GDBserver tracking GDB Z1 breakpoints in its breakpoint structures
like Z0 breakpoints are, but the latter case still needs handling.
add_breakpoint_commands has the same issue, though at present I don't
know any way to trigger it other than sending a manually cooked
packet.

Unbelievably, it doesn't look like we have any test that tries setting
a conditional hardware breakpoint.  Looking at cond-eval-mode.exp, it
looks like the file was meant to actually test something, but it's
mostly empty today.  This patch adds tests that tries all sorts of
conditional breakpoints and watchpoints.  The test hangs/fails without
the GDBserver fix.

10 years agobreakpoint shadowing, take single-step breakpoints into account.
Pedro Alves [Thu, 10 Apr 2014 13:19:52 +0000 (14:19 +0100)] 
breakpoint shadowing, take single-step breakpoints into account.

Breakpoints are supposed to be transparent to memory accesses.  For
all kinds of breakpoints breakpoint_xfer_memory hides the breakpoint
instructions.  However, sss breakpoints aren't tracked like all other
breakpoints, and nothing is taking care of hiding them from memory
reads.

Say, as is, a background step + disassemble will see breakpoints
instructions on software step targets.  E.g., stepping over this line:

  while (1);

with s&

and then "disassemble" would show sss breakpoints.

Actually, that's still not be possible to see today, because:

 - in native Linux, you can't read memory while the program
   is running.
 - with Linux gdbserver, you can, but in the all-stop RSP you
   can't talk to the server while the program is running...
 - and with non-stop, on software step targets, we presently
   force the use of displaced-stepping for all single-steps,
   so no single-step breakpoints are used...

I've been working towards making non-stop not force displaced stepping
on sss targets, and I noticed the issue then.  With that, I indeed see
this:

(gdb) set remote Z-packet off
(gdb) s&
(gdb) disassemble main
Dump of assembler code for function main:
   0x000000000040049c <+0>:     push   %rbp
   0x000000000040049d <+1>:     mov    %rsp,%rbp
   0x00000000004004a0 <+4>:     int3
   0x00000000004004a1 <+5>:     (bad)
End of assembler dump.

Instead of the correct:

(gdb) disassemble main
Dump of assembler code for function main:
   0x000000000040049c <+0>:     push   %rbp
   0x000000000040049d <+1>:     mov    %rsp,%rbp
   0x00000000004004a0 <+4>:     jmp    0x4004a0 <main+4>

This is actually one thing that my v1 of the recent "fix a bunch of
run control bugs" series was fixing, because it made sss breakpoints
be regular breakpoints in the breakpoint chain.  But dropped it in the
version that landed in the tree, due to some problems.

So instead of making sss breakpoints regular breakpoints, go with a
simpler fix (at least for now) -- make breakpoint_xfer_memory take
software single-step breakpoints into account.  After the patch, I get
the correct disassemble output.

Tested on x86_64 Fedora 17, and also on top of my "use software
single-step on x86" series.

10 years ago[varobj] false type-changed status for reference to Ada array
Joel Brobecker [Thu, 20 Mar 2014 14:43:08 +0000 (07:43 -0700)] 
[varobj] false type-changed status for reference to Ada array

Given the following variable...

   BT : Bounded := New_Bounded (Low => 1, High => 3);

... where type Bounded is defined as a simple unconstrained array:

   type Bounded is array (Integer range <>) of Integer;

Creating a varobj for that variable, and immediately asking for
varobj updates, GDB says that our varobj changed types!

    (gdb)
    -var-create bt * bt
    ^done,name="bt",numchild="3",value="[3]",type="<ref> array (1 .. 3) of integer",has_more="0"
    (gdb)
    -var-update 1 *
    ^done,changelist=[{name="bt",value="[3]",in_scope="true",type_changed="true",new_type="<ref> array (1 .. 3) of integer",new_num_children="3",has_more="0"}]

The expected output for the -var-update command is, in this case:

    (gdb)
    -var-update 1 *
    ^done,changelist=[]

The problem occurs because the ada-varobj module does not handle
references, and while the references gets stripped when the varobj
gets created, it doesn't when computing varobj updates.

More specifically, when creating the varobj, varobj_create creates
a new value which is a reference to a TYPE_CODE_ARRAY. It then calls
install_new_value which calls coerce_ref with the following comment:

    /* We are not interested in the address of references, and given
       that in C++ a reference is not rebindable, it cannot
       meaningfully change.  So, get hold of the real value.  */
    if (value)
      value = coerce_ref (value);

This leaves the varobj's type component still a ref, while
the varobj's value is now our array, without the ref. This explains
why the "value" field in the varobj indicates an array with 3 elements
"[3]" while the "type" field shows a ref to an array. Generally
speaking, most users have said that showing the ref was a useful
piece of information, so this patch is not touching this part.

Next, when the user issues the -var-update request, varobj_update
calls value_of_root to compute the varobj's new value as well as
determine whether the value's type has changed or not. What happens
in a nutshell is that it calls value_of_root_1 (which re-evaluates
the expression and returns the corresponding new value), finds that
the new value is not NULL, and thus asks whether it has mutated:

    else if (varobj_value_has_mutated (var, value, value_type (value)))

This then indirectly delegates the determination to the language-specific
callback, which fails, because it does not handle references.

This patch fixes the issue by adjusting varobj_value_has_mutated to
expect references, and strip them when seen. This allows the various
language-specific implementations to remain unaware of references.

gdb/ChangeLog:

        * varobj.c (varobj_value_has_mutated): If NEW_VALUE is
        a reference, strip the reference layer before calling
        the lang_ops value_has_mutated callback.

gdb/testsuite/ChangeLog:

        * gdb.ada/mi_dyn_arr: New testcase.

10 years agoRemove `expout*' globals from parser-defs.h

Remove `expout*' globals from parser-defs.h

This commit removes the "expout*" globals from our parser code, turning
them into a structure that is passed when an expression needs to be
evaluated.  This is the initial step to make our parser less
"globalized".

This is mostly a mechanical patch, which creates a structure containing
the "expout*" globals and then modify all the functions that handle them
in order to take the structure as argument.  It is big, and has been
reviewed at least 4 times, so I think everything is covered.
