gdbserver: Remove gdb_id_to_thread_id

From what I understand, this function is not doing anything useful as of
today.

Here's the result of my archeological research:

- The field thread_info::gdb_id was added in

  a06660f7  Use LWP IDs for thread IDs in gdbserver

  There was problem when using a 32-bits gdb with a 64-bits gdbserver.
  For some reason that I don't fully understand, the thread ids
  exchanged between gdb and gdbserver could overflow a 32 bits data
  type.  My guess is that they were the thread address (e.g. the
  0x7ffff7f20b40 in "Thread 0x7ffff7f20b40 (LWP 1058)" today).  This
  patch changed that so gdb/gdbserver would talk in terms of the OS
  assigned numerical id (as shown in ps).  It therefore added a way to
  convert between this gdb_id (the numerical id) and the thread id (the
  address).

95954743cb  Implement the multiprocess extensions, and add linux
              multiprocess supportNon-stop mode support.

  This patch made gdbserver deal with threads using their numerical ids
  and not the address-like id.  Starting from there, the gdb_id <->
  thread id conversion was not needed anymore, since the remote protocol
  and gdbserver were using the same kind of ids again.  The gdb_id field
  in the thread_info structure was also unused starting there.

d50171e4  Teach linux gdbserver to step-over-breakpoints.

  This patch moved the thread_info structure around, and got rid of the
  gdb_id field (which was unused).

Looking at the implementation of gdb_id_to_thread_id, it is not doing
anything useful.  It is looking up a thread by ptid using
find_thread_ptid, which basically loops over all threads looking at
their entry.id field.  If a thread with that ptid is found, it returns
its entry.id field.  So it will always return the same thing as it input
(with the exception of if no thread exist with that ptid, then it will
return null_ptid).

Make dwarf_expr_context::stack an std::vector

Replace the manually managed array with a vector.  It is mostly
straightforward, except maybe one thing in execute_stack_op, in the
handling of DW_OP_fbreg.  When the code stumbles on that opcode while
evaluating an expression, it needs to evaluate a subexpression to find
where the fb reg has been saved.  Rather than creating a new context, it
reuses the current context.  It saves the size of the stack before and
restores the stack to that size after.

I think we can do a little bit better by saving the current stack
locally and installing a new empty stack.  This way, if the
subexpression is malformed and underflows, we'll get an exception.
Before, it would have overwritten the top elements of the top-level
expression.  The evaluation of the top-level expression would have then
resumed with the same stack size, but possibly some corrupted elements.

seems like enable_probes_command and disable_probes_command were not

The comparison function compare_probes needs to be updated to return a
bool indicating whether the first parameter is "less than" the second

I defined two constructors to bound_probe.  The default constructor is
needed, for example, so the instance in struct bp_location can be
constructed without parameters.  The constructor with parameters is
useful so we can use emplace_back and pass the values directly.

Fix build breakage on GNU/Linux AArch64, take 2

The last commit unfortunately was not enough to fix the build breakage
on AArch64.  I made a mistake and did not test it alone on BuildBot,
but along with another patch that was responsible for fixing the
breakage.

The failure is:

  In file included from /usr/include/string.h:640:0,
   from build-gnulib-gdbserver/import/string.h:41,
   from ../../../binutils-gdb/gdb/gdbserver/../common/common-defs.h:56,

 __warn_memset_zero_len ();

This is likely due to a GCC bug, because for some reason the compiler
assumes that the third argument to the memset:

  memset (regcache->register_status, REG_UNAVAILABLE,
  VEC_length (tdesc_reg_p, regcache->tdesc->reg_defs));

is always zero, which is not always true.

Anyway, the simple fix for this is to guard the memset calls with:

  if (!VEC_empty (tdesc_reg_p, regcache->tdesc->reg_defs))

This time, I made sure to regtest only this patch on BuildBot, and it
finally solved the breakage.

7 years agogdb: Remove check for gdb_stderr == NULL
Andrew Burgess [Sun, 6 Aug 2017 20:45:08 +0000 (21:45 +0100)]
gdb: Remove check for gdb_stderr == NULL

Recent changes made gdb_stderr a macro:

  #define gdb_stderr (*current_ui_gdb_stderr_ptr ())

and current_ui_gdb_stderr_ptr return this:

   &current_ui->m_gdb_stderr

The problem is that this is undefined if current_ui is NULL, which can
happen early on during gdb start up.

If we run into an error during early gdb start up then we write the
error message to gdb_stderr.  However, if we are too early during the
start up then current_ui is NULL, and using the gdb_stderr macro
triggers undefined behaviour.

We try to avoid this using a check 'gdb_stderr == NULL' which was fine
before the recent changes, but now, still triggers undefined behaviour.

A better check is instead 'current_ui == NULL' which is what I use in
this patch.

Triggering this failure is pretty hard, most of the really early errors
are only triggered if pretty basic things are not as expected, for
example, if the default signal handlers are not as expected.  Seeing one
of these errors trigger usually means that someone working on gdb has
made an incorrect change.  Still, the errors are present in gdb, and
should we ever trigger one it would be nice if gdb didn't crash.

For testing this change I've been applying this patch which adds an
unconditional error into a function called early during gdb start up.
Later in the same function is a real error call which, in some
circumstances could be triggered:

Use ui_out_emit_tuple in more places

This changes more places to use ui_out_emit_tuple, removing cleanups.

ChangeLog
2017-09-09  Tom Tromey  <tom@tromey.com>

* target.c (flash_erase_command): Use ui_out_emit_tuple.
* stack.c (print_frame): Use ui_out_emit_tuple.
* spu-tdep.c (info_spu_event_command): Use ui_out_emit_tuple.
(info_spu_mailbox_command, info_spu_dma_command)
(info_spu_proxydma_command): Likewise.
* mi/mi-main.c (mi_cmd_trace_frame_collected): Use
ui_out_emit_tuple, gdb::byte_vector, bin2hex.
* mi/mi-cmd-file.c (mi_cmd_file_list_shared_libraries): Use
ui_out_emit_tuple.
* breakpoint.c (print_it_watchpoint): Use ui_out_emit_tuple.

Remove make_cleanup_ui_out_table_begin_end

This changes the few remaining uses of
make_cleanup_ui_out_table_begin_end to use ui_out_emit_table instead,
and then removes the cleanup.

ChangeLog
2017-09-09  Tom Tromey  <tom@tromey.com>

* ui-out.h (make_cleanup_ui_out_table_begin_end): Remove.
(class ui_out_emit_table): Update comment.
* ui-out.c (do_cleanup_table_end)
(make_cleanup_ui_out_table_begin_end): Remove.
* spu-tdep.c (info_spu_mailbox_list): Use ui_out_emit_table.

* probe.c (info_probes_for_ops): Use ui_out_emit_table.
* darwin-nat-info.c (darwin_debug_regions_recurse): Use
ui_out_emit_table.

This changes print_thread_info_1 to use ui_out_emit_table and
ui_out_emit_list.  Which one is used depends on whether the ui-out is
mi-like; so the emitters are wrapped in gdb::optional.

This ends up manifesting due to the two-byte compressed NOP that's
pessimisticly emitted by the ".align 2", which results in "rvc_boundry"
being 2-byte aligned.  frag_align_code() then goes and outputs a 2-byte
NOP (which is invalid in no-RVC mode) to align the code back to a 4-byte
boundry, which can't be relaxed away by the linker as it's not part of
the R_RISCV_RELAX relocation.

The fix is to just always emit the worst case possible alignment into
the output as a single R_RISCV_RELAX, which the linker will then fix up.

With this patch I get the expected code generation

Cast char constant to int in sizeof.exp

PR gdb/22010 concerns a regression I introduced with the scalar
printing changes.  The bug is that this code in sizeof.exp:

    set signof_byte [get_integer_valueof "'\\377'" -1]

can incorrectly compute sizeof_byte.  One underlying problem here is
that gdb's C parser doesn't treat a char constant as an int (this is
PR 19973).

However, it seems good to have an immediate fix for the regression.
The simplest is to cast to an int here.
