For now, let's focus only on the *stopped event.  We see that the
async output is missing frame info.  And this causes a test failure in
async mode, as "mi_expect_stop solib-event" wants to see the frame
info.

However, if we compare the event output when a real MI execution
command is used, compared to a CLI command (e.g., run vs -exec-run,
next vs -exec-next, etc.), we see:

As seen above, with MI commands, the *stopped event _doesn't_ have
frame info.  This is because normal_stop, as commanded by the result
of bpstat_print, skips printing frame info in this case (it's an
"event", not a "breakpoint"), and when the interpreter is MI,
mi_on_normal_stop skips calling print_stack_frame, as the normal_stop
call was already done with the MI uiout.  This explains why the async
output is different even with a CLI command.  Its because in async
mode, the mi_on_normal_stop path is always taken; it is always reached
with the MI uiout, because the stop is handled from the event loop,
instead of from within `proceed -> wait_for_inferior -> normal_stop'
with the interpreter overridden, as in sync mode.

This patch fixes the issue by making all cases output the same
*stopped event, by factoring out the print code from normal_stop, and
using it from mi_on_normal_stop as well.  I chose the *stopped output
without a frame, mainly because that is what you already get if you
use MI execution commands, the commands frontends are supposed to use
(except when implementing a console).  This patch makes it simpler to
tweak the MI output differently if desired, as we only have to change
the centralized print_stop_event (taking into account whether the
uiout is MI-like), and all different modes will change accordingly.

Tested on x86_64 Fedora 17, no regressions.  The mi-solib.exp test no
longer fails in async mode with this patch, so the patch removes the
kfail.

[Ada] Crash with references to GNAT packed arrays handling

Consider the following declarations:

  type Packed_Array is array (Natural range <>) of Boolean;
  pragma Pack (Packed_Array);

  function Make (H, L : Natural) return Packed_Array is

  end Make;

  A1 : Packed_Array := Make (1, 2);
  A2 : Packed_Array renames A1;

One possible DWARF translation for A2 is:

  <3><1e4>: Abbrev Number: 21 (DW_TAG_variable)
     <1e5>   DW_AT_name                 : a2

     <177>   DW_AT_name                 : foo__Ta1S
     <17b>   DW_AT_GNAT_descriptive_type: <0x223>

Here, foo__Ta1S___XP1 is the type used for the code generation while
foo__Ta1S is the source-level type. Both form a valid GNAT encoding for
a packed array type.

Trying to print A2 (1) can make GDB crash. This is because A2 is defined
as a reference to a GNAT encoding for a packed array. When decoding
constrained packed arrays, the ada_coerce_ref subprogram follows
references and returns a fixed type from the target type, peeling
the GNAT encoding for packed arrays. The remaining code assumes that
the resulting type is still such an encoding while we only have
a standard GDB array type, hence the crash:

  arr = ada_coerce_ref (arr);
  [...]
  type = decode_constrained_packed_array_type (value_type (arr));

decode_constrained_packed_array_type assumes that its argument is
such an encoding. From its front comment:

  /* The array type encoded by TYPE, where
     ada_is_constrained_packed_array_type (TYPE).  */

This patch simply replaces the call to ada_coerce_ref with a call
to coerce_ref in order to avoid prematurely transforming
the packed array type as a side-effect. This way, the remaining code
will always work with a GNAT encoding.

10 years agofix regressions with target-async
Tom Tromey [Fri, 28 Feb 2014 16:47:34 +0000 (09:47 -0700)] 
fix regressions with target-async

A patch in the target cleanup series caused a regression when using
record with target-async.  Version 4 of the patch is here:

    https://sourceware.org/ml/gdb-patches/2014-03/msg00159.html

The immediate problem is that record supplies to_can_async_p and
to_is_async_p methods, but does not supply a to_async method.  So,
when target-async is set, record claims to support async -- but if the
underlying target does not support async, then the to_async method
call will end up in that method's default implementation, namely
tcomplain.

This worked previously because the record target used to provide a
to_async method; one that (erroneously, only at push time) checked the
other members of the target stack, and then simply dropped to_async
calls in the "does not implement async" case.

My first thought was to simply drop tcomplain as the default for
to_async.  This works, but Pedro pointed out that the only reason
record has to supply to_can_async_p and to_is_async_p is that these
default to using the find_default_run_target machinery -- and these
defaults are only needed by "run" and "attach".

So, a nicer solution presents itself: change run and attach to
explicitly call into the default run target when needed; and change
to_is_async_p and to_can_async_p to default to "return 0".  This makes
the target stack simpler to use and lets us remove the method
implementations from record.  This is also in harmony with other plans
for the target stack; namely trying to reduce the impact of
find_default_run_target.  This approach makes it clear that
find_default_is_async_p is not needed -- it is asking whether a target
that may not even be pushed is actually async, which seems like a
nonsensical question.

While an improvement, this approach proved to introduce the same bug
when using the core target.  Looking a bit deeper, the issue is that
code in "attach" and "run" may need to use either the current target
stack or the default run target -- but different calls into the target
API in those functions could wind up querying different targets.

This new patch makes the target to use more explicit in "run" and
"attach".  Then these commands explicitly make the needed calls
against that target.  This ensures that a single target is used for
all relevant operations.  This lets us remove a couple find_default_*
functions from various targets, including the dummy target.  I think
this is a decent understandability improvement.

One issue I see with this patch is that the new calls in "run" and
"attach" are not very much like the rest of the target API.  I think
fundamentally this is due to bad factoring in the target API, which
may need to be fixed for multi-target.  Tackling that seemed ambitious
for a regression fix.

While working on this I noticed that there don't seem to be any test
cases that involve both target-async and record, so this patch changes
break-precsave.exp to add some.  It also changes corefile.exp to add
some target-async tests; these pass with current trunk and with this
patch applied, but fail with the v1 patch.

This patch differs from v4 in that it moves initialization of
to_can_async_p and to_supports_non_stop into inf-child, adds some
assertions to complete_target_initialization, and adds some comments
to target.h.

[Ada] Full view of tagged type with ptype

When evaluating an expression, if it is of a tagged type, GDB reads
the tag in memory and deduces the full view. At parsing time, however,
this operation is done only in the case of OP_VAR_VALUE. ptype does
not go through a full evaluation of expressions so it may return some
odd results:

 (gdb) print c.menu_name
 $1 = 0x0
 (gdb) ptype $
 type = system.strings.string_access
 (gdb) ptype c.menu_name
 type = <void>

This change removes this peculiarity by extending the tag resolution
to UNOP_IND and STRUCTOP_STRUCT. As in the case of OP_VAR_VALUE, this
implies switching from EVAL_AVOID_SIDE_EFFECTS to EVAL_NORMAL when a
tagged type is dereferenced.

Better overflow checking for powerpc32 relocations

Similar to the powerpc64 patch, this improves overflow checking in
elf32-ppc.c.  Many reloc "howto" entries needed fixes, some just
cosmetic.

The patch also fixes the R_PPC_VLE_SDA21 reloc application code, which
was horribly broken.  In fact, it may still be broken since Power ISA
2.07 says e_li behaves as
   RT <- EXTS(li20 1:4 || li20 5:8 || li20 0 || li20 9:19)
where li20 is a field taken from bits 17..20, 11..15, 21..31 of the
instruction.  Freescale VLEPEM says differently, and I assume
correctly, that
   RT <- EXTS(li20 0:3 || li20 4:8 || li20 9:19)
The VLE_SDA21 relocation description matches this too.

Now the VLE_SDA21 relocation specifies in the case where e_addi16 is
converted to e_li for symbols in .PPC.EMB.sdata0 or .PPC.EMB.sbss0
(no base register), that the field is restricted to 16 bits, with the
sign bit being propagated to the top 4 bits.  I don't see the sense in

Better overflow checking for powerpc64 relocations

R_PPC64_ADDR16 is used in three contexts:
- .short data relocation
- 16-bit signed insn fields, eg. addi
- 16-bit unsigned insn fields, eg. ori
In the first case we want to allow both signed and unsigned 16-bit
values, the latter two ought to error if the field exceeds the range
of values allowed for 16-bit signed and unsigned integers
respectively.  These conflicting requirements meant that ld had to
choose the least restrictive overflow checks, and thus it is possible
to construct testcases where an addi field overflows but is not
reported by ld.  Many relocations dealing with 16-bit insn fields have
this problem.  What's more, some relocations that are only ever used
for signed fields of instructions woodenly copied the lax overflow
