Remove last Ada cleanups
This removes the last cleanups from the Ada code by changing
ada_lookup_symbol_list's out parameter to be a std::vector, and then

(windows) GDB/MI crash when using "-list-thread-groups --available"
On Windows, using the "-list-thread-groups --available" GDB/MI command

Ooops!
The SEGV happens because the -list-thread-groups --available command
triggers a windows_nat_target::xfer_partial call for a TARGET_OBJECT_OSDATA
object. Until a program is being debugged, the target_ops layer that
gets the call is the Windows "native" layer. Except for a couple of
specific objects (TARGET_OBJECT_MEMORY and TARGET_OBJECT_LIBRARIES),
this layer's xfer_partial method delegates the xfer of other objects
to the target beneath:
default:
return beneath->xfer_partial (object, annex,
readbuf, writebuf, offset, len,
xfered_len);
Unfortunately, there is no "beneath layer" in this case, so
beneath is NULL and dereferencing it leads to the SEGV.
This patch fixes the issue by checking beneath before trying
to delegate the request.

[Inferior 1 (process 32470) exited normally]
The "a'address" is Ada speak for function A's address ("A" by
itself means the result of calling A with no arguments). The
transcript above shows that we're having problems trying to
parse the breakpoint location while re-setting it. As a result,
we also fail to stop at the breakpoint.
Normally, breakpoint locations are evaluated with the current_language
being set to the language of the breakpoint. But, unfortunately for us,
what happened in this case is that parse_exp_in_context_1 calls
get_selected_block which eventually leads to a call to select_frame
because the current_frame hadn't been set yet. select_frame then
finds that our language_mode is auto, and therefore changes the
current_language to match the language of the frame we just selected.
In our case, the language chosen was 'c', which of course is not
able to parse an Ada expression, hence the error.
This patch prevents this by forcing the language_mode to manual
before we call breakpoint_re_set_one.

Remove TYPE_TAG_NAME
TYPE_TAG_NAME has been an occasional source of confusion and bugs. It
seems to me that it is only useful for C and C++ -- but even there,
not so much, because at least with DWARF there doesn't seem to be any
way to wind up with a type where the name and the tag name are both
non-NULL and different.
So, this patch removes TYPE_TAG_NAME entirely. This should save a
little memory, but more importantly, it simplifies this part of gdb.
A few minor test suite adjustments were needed. In some situations
the new code does not yield identical output to the old code.

Fix "set" handling of Python parameters
It's long bothered me that setting a Python parameter from the CLI

bit by providing a "get_set_string" method, if this method returns an
empty string, a blank line will be printed.
This patch removes the "help" behavior and changes the get_set_string
behavior to avoid printing a blank line. The code has a comment about
preserving API behavior, but I don't think this is truly important;

arch-utils: Make the last endianness actually chosen sticky
Use the last endianness explicitly selected, either by choosing a binary

As observed with the `gdb.base/step-over-no-symbols.exp' test case when
discarding the binary file even while connected to a live target the
endianness automatically selected is reset to the GDB target's default,
even if it does not match the endianness of the target being talked to.
For example with a little-endian MIPS target and the default endianness
being big we get this:

which shows that with the removal of the executable debugged the
endianness of $pc still at `main' gets swapped and the value in that
register is now incorrectly interpreted as 0x40084000 rather than
0x400840 as shown earlier on with the `break' command. Consequently the
debug session no longer works as expected, until the endianness is
overridden with an explicit `set endian little' command.
This will happen while working with any target hardware whose endianness
does not match the default GDB target's endianness guessed and recorded
for a later use in `initialize_current_architecture'.
Given that within a single run of GDB it is more likely that consecutive
target connections will use the same endianness than that the endianness
will be swapped between connections, it makes sense to preserve the last
endianness explicitly selected as the automatic default. It will make a
session like above, where an executable is removed, work correctly and
will retain the endianness for a further reconnection to the target.
And the new automatic default will still be overridden by subsequently
choosing a binary to debug, or with an explicit `set endian' command.
With the change in place the test case above completes successfully:

Mark END_CATCH as ATTRIBUTE_NORETURN (-Wmaybe-uninitialized warnings)
This commit fixes a set of -Wmaybe-uninitialized warnings in GDB and
GDBserver, seen with GCC 7.3.1 on F27 at -O2. Specifically, all of
these:
src/gdb/breakpoint.c:5040:4: warning: ‘e’ may be used uninitialized in this function [-Wmaybe-uninitialized]
src/gdb/cli/cli-cmds.c:277:71: warning: ‘tracker’ may be used uninitialized in this function [-Wmaybe-uninitialized]
src/gdb/cli/cli-cmds.c:302:22: warning: ‘word’ may be used uninitialized in this function [-Wmaybe-uninitialized]
src/gdb/gdbserver/server.c:1895:7: warning: ‘result’ may be used uninitialized in this function [-Wmaybe-uninitialized]
src/gdb/gdbserver/server.c:1966:7: warning: ‘result’ may be used uninitialized in this function [-Wmaybe-uninitialized]
For example, looking at one of the gdbserver ones in more detail:
../../../src/gdb/gdbserver/server.c: In function ‘int handle_qxfer_btrace_conf(const char*, gdb_byte*, const gdb_byte*, ULONGEST, LONGEST)’:
../../../src/gdb/gdbserver/server.c:1966:7: warning: ‘result’ may be used uninitialized in this function [-Wmaybe-uninitialized]
if (result != 0)
^~
In this case (like the others), the 'result' variable is assigned in
both TRY and CATCH blocks:
TRY
{
result = target_read_btrace_conf (thread->btrace, &cache);
if (result != 0)
memcpy (own_buf, cache.buffer, cache.used_size);
}
CATCH (exception, RETURN_MASK_ERROR)
{
sprintf (own_buf, "E.%s", exception.message);
result = -1;
}
END_CATCH
if (result != 0)
return -3;
so it would seem like the warning is bogus.
However, END_CATCH is really a catch block in disguise, and that path
indeed does not initialize the variable:
#define END_CATCH \
catch (...) \
{ \
exception_rethrow (); \
} \
}
exception_rethrow does not return normally (it rethrows the current
exception after running cleanups), but the compiler can not see that.
If it could return normally, then indeed 'result' could be used
uninitialized if the TRY block threw some non-gdb exception, which
would be caught by END_CATCH.
The fix it to let the compiler know that the exception_rethrow does
not return normally, using ATTRIBUTE_NORETURN.

Removing lookup_minimal_symbol_and_objfile
Function lookup_minimal_symbol_and_objfile iterates on all objfiles and
calls lookup_minimal_symbol for each of them, effectively searching in all
objfiles. lookup_bound_minimal_symbol calls lookup_minimal_symbol with NULL,
which also effectively searches all objfiles. AFAIK, they do exactly the same
thing, so we can get rid of one (and lookup_minimal_symbol_and_objfile happens
to be the most inefficient because it ends up n^2 on the number of objfiles).

PR23235, make check uses system installed ld
This patch doesn't stop the build-id and debuglink tests using the
installed ld, it just prevents a compiler failure from resulting in a
test fail. We could move the tests to the ld testsuite but it doesn't
seem all that important.

ld: Add _bfd_elf_link_hide_sym_by_version
bfd_hide_sym_by_version can't be used to check if a versioned symbol is

both versioned and unversioned symbols by extracting versioned symbol

Clear entire "location" in value constructor
My recent change to allocate values with "new" may have introduced a
small bug. In particular, the previous code allocated with XCNEW, but
the new code only clears a part of the "location" field in the
constructor. I didn't try very hard to actually trigger a bug here,
the problem remains theoretical.
This patch just arranges to initialize the entire location.
