This is a problem that I noticed on GNU/Linux, when using both GDB
and GDBserver to debug an Ada program. To reproduce, use any Ada
program, built with debug info ("gnatmake -g ...").
Then start the program with gdbserver:
% gdbserver :4444 simple_main
And then insert a breakpoint using the name of an Ada function,
followed by connecting to the target server:
(gdb) b simple.test_simple
Breakpoint 1 at 0x401f28: file simple.adb, line 16.
(gdb) tar rem :4444
Remote debugging using :4444
Reading symbols from /lib64/ld-linux-x86-64.so.2...
Reading symbols from /usr/lib/debug/lib/ld-2.11.1.so...done.
done.
Loaded symbols for /lib64/ld-linux-x86-64.so.2
!! -> Error in re-setting breakpoint 1: Can't find member of namespace, class,
!! -> struct, or union named "simple.test_simple"
!! -> Hint: try 'simple.test_simple<TAB> or 'simple.test_simple<ESC-?>
!! -> (Note leading single quote.)
0x00007f4db3cf2af0 in _start () from /lib64/ld-linux-x86-64.so.2
Created trace state variable $trace_timestamp for target's variable 1.
The problem is related to the fact that GDB found debug symbols for
ld.so in /usr/lib/debug. For debugger configured with a prefix that
is different from /usr, one way to force the problem to reproduce is
to use:
(gdb) set debug-file-directory /usr/lib/debug
(assuming that debug info has been installed at that location).
The problem is that the wrong language is used to parse the breakpoint
location because it gets changed from under us as a side effect of
some of the code that we do in prepration for re-parsing. In particular,
breakpoint_re_set_one reads:
set_language (b->language);
input_radix = b->input_radix;
s = b->addr_string;
save_current_space_and_thread ();
switch_to_program_space_and_thread (b->pspace);
marker_spec = b->type == bp_static_tracepoint && is_marker_spec (s);
[if (marker_spec) decode_tracepoint_spec (...) else decode_line_1]
What happens in our case is that debugging information gets found
for ld.so. As a result, the current_frame language is C whereas it
would have been unknown if we did not have debugging info. And
save_current_space_and_thread() implicitly causes the current frame
to be selected, which changes the language automatically if the new
language is not uknown and the the language mode is auto.
The fix, until all parsing routines (including decode_line_1) get upgraded
to take a language, is to select the breakpoint language as late as possible.
In this case, we don't need to do that until we actually try to parse
the breakpoint addr_string.
gdb/ChangeLog:
* breakpoint.c (breakpoint_re_set_one): Move call to set_language
down, just before the block that parse the breakpoint addr_string.
This patch moves a couple of write-after-approval names up to keep
the list in alphabetical order.

This is on GNU/Linux.
GDBserver does not exit properly when the inferior exits, as demonstrated
with any program using the procedure below:
% gdbserver-head :4444 simple_main
Process simple_main created; pid = 25681
Listening on port 4444
Then, in another terminal, start GDB, connect to GDBserver, and run
the program to completion:
% gdb-head simple_main
(gdb) tar rem :4444
(gdb) cont
Continuing.
Program exited normally.
Going back to the terminal where GDBserver is running, we see the following
output:
Child exited with status 0
readchar: Got EOF
Remote side has terminated connection. GDBserver will reopen the connection.
Listening on port 4444
The problem is that we're missing a call to mourn_inferior. As a result,
after we've handled the vCont packet, we fail to notice that there are
no process left to debug (target_running() returns true), and thus try
to continue reading from the remote socket. However, since GDB just
disconnected after having received the "exit with status 0" reply to the
vCont request, the read triggers the EOF exception.

The debugger fails to build when configure with --python-python=<path>
where <path> is a non-system location. The reason is a warning made
fatal due to the definition of _XOPEN_SOURCE inside pyconfig.h. This
is exactly the same problem as with _POSIX_C_SOURCE, handled in
python-internal.h as follow:
| /* /usr/include/features.h on linux systems will define _POSIX_C_SOURCE
| if it sees _GNU_SOURCE (which config.h will define).
| pyconfig.h defines _POSIX_C_SOURCE to a different value than
| /usr/include/features.h does causing compilation to fail.
| To work around this, undef _POSIX_C_SOURCE before we include Python.h. */
| #undef _POSIX_C_SOURCE
This patch fixes this problem the same way.

sign-extending from ctx->addr_size bytes as needed. Read DW_OP_addr
values and DW_OP_deref results as unsigned integers.
* dwarf2loc.c (read_pieced_value): Update for struct dwarf_expr_piece
changes.
(write_pieced_value): Likewise.
(dwarf2_evaluate_loc_desc): Use dwarf_expr_fetch_address instead of
dwarf_expr_fetch when appropriate.
(compile_dwarf_to_ax): Read DW_OP_addr values as unsigned integers.
* dwarf2-frame.c (execute_stack_op): Use dwarf_expr_fetch_address
instead of dwarf_expr_fetch when appropriate.
testsuite/ChangeLog:
* gdb.cell/dwarfaddr.exp: New file.
* gdb.cell/dwarfaddr.S: New file.
Python scripts to be used by GDB can be stored in that directory,
and will be automatically found by the interpreter when importing them.
This patch also sets up <gdb_pythondir>/gdb as the directory where gdb
submodules can be stored. For now, there is nothing there, but it can
now be added easily without further code changes.
