Have regdat.sh always rewrite the output register file
The rules for generating the output register files look like:
amd64.c : $(srcdir)/../regformats/i386/amd64.dat $(regdat_sh)
$(SHELL) $(regdat_sh) $(srcdir)/../regformats/i386/amd64.dat amd64.c
According to this rule, if regdat.sh is newer than amd64.c, then
regdat.sh shall be invoked on amd64.dat. According to regdat.sh, if the
script determines that the output file amd64.c has not changed, then it
will not overwrite the existing output file. This means that a
subsequent invocation of make will trigger the above rule again as
regdat.sh will be perpetually newer than amd64.c.
This then shows up in the make output like so:
/bin/bash ./../regformats/regdat.sh ./../regformats/i386/amd64-linux.dat amd64-linux.c
amd64-linux.c unchanged.
/bin/bash ./../regformats/regdat.sh ./../regformats/i386/amd64-avx-linux.dat amd64-avx-linux.c
amd64-avx-linux.c unchanged.
...
To fix this pathological behavior, it suffices to have regdat.sh
unconditionally rewrite the output register file.
On my machine, which has a regdat.sh file that is newer than some of the
input register files, this change speeds up every invocation of make
under gdb/ by about 5 seconds.

Error on shared lib call to @local ifunc
On powerpc32, making ifuncs have non-default visibility in shared
libraries or pies can result in runtime failures. The problem is that
if gcc is told that a given function has non-default visibility, then
calls to that function are assumed to be local (which is true) and
thus need not go via a plt call stub (which is false for ifunc). If
the caller has no other reason to set up the got pointer (r30), code
won't be emitted to do so. However, a pic plt call stub makes use of
r30 to load the plt entry. So a call to an ifunc, which always needs
a plt entry, will fail.
This patch makes ld emit an error for the problem case, and allows
calls to non-default visibility ifuncs to work in normal executables.
I also fix some cases where ifuncs fail when using the old bss-plt.

Since upstream gcc has recently increased the function alignment on
S390, the dw2-dir-file-name test case fails in the first
gdb_continue_to_breakpoint. Indeed, the breakpoint is now placed into
the alignment gap *before* the actual function.
This happens because the test case declares the respective "*_start"
symbol as a "loose" label before the function definition, and the
compiler inserts the alignment between that label and the function
itself.
The "*_start" symbols were only necessary because FUNC made the
function static. The fix makes the functions extern instead, thus
making the "*_start" labels unnecessary.

Handle the case of a remote target supporting target side commands, but not on software breakpoints.
Although we can tell upfront whether a remote target supports target
side commands, we can only tell whether the target supports that in
combination with a given breakpoint kind (software, hardware,
watchpoints, etc.) when we go and try to insert such a breakpoint kind
the first time. It's not desirable to make remote_insert_breakpoint
simply return -1 in this case, because if the breakpoint was set in a
shared library, insert_bp_location will assume that the breakpoint
insertion failed because the library wasn't mapped in.
insert_bp_location already handles errors/exceptions thrown from the
target_insert_xxx methods, exactly so the backend can tell the user
the detailed reason the insertion of hw breakpoints failed. But, in
the case of software breakpoints, it discards the detailed error
message.
So the patch makes insert_bp_location use the error's message for SW
breakpoints too, and, introduces a NOT_SUPPORTED_ERROR error code so
that insert_bp_location doesn't confuse the error for failure due to a
shared library disappearing.
The result is:

[remote/gdbserver] Don't lose signals when reconnecting.
Currently, when GDB connects in all-stop mode, GDBserver always
responds to the status packet with a GDB_SIGNAL_TRAP, even if the
program is actually stopped for some other signal.
(gdb) tar rem ...
...
(gdb) c
Program received signal SIGUSR1, User defined signal 1.
(gdb) disconnect
(gdb) tar rem ...
(gdb) c
(Or a GDB crash instead of an explicit disconnect.)
This results in the program losing that signal on that last continue,
because gdb will tell the target to resume with no signal (to suppress
the GDB_SIGNAL_TRAP, due to 'handle SISGTRAP nopass'), and that will
actually suppress the real signal the program had stopped for
(SIGUSR1). To fix that, I think we should make GDBserver report the
real signal the thread had stopped for in response to the status
packet:
@item ?
@cindex @samp{?} packet
Indicate the reason the target halted. The reply is the same as for
step and continue.
But, that raises the question -- which thread are we reporting the
status for? Due to how the RSP in all-stop works, we can only report
one status. The status packet's response is a stop reply packet, so
it includes the thread identifier, so it's not a problem packet-wise.
However, GDBserver is currently always reporting the status for first
thread in the thread list, even though that may well not be the thread
that got the signal that caused the program to stop. So the next
logical step would be to report the status for the
last_ptid/last_status thread (the last event reported to gdb), if it's
still around; and if not, fallback to some other thread.
There's an issue on the GDB side with that, though...
GDB currently always adds the thread reported in response to the
status query as the first thread in its list. That means that if we
start with e.g.,
(gdb) info threads
3 Thread 1003 ...
* 2 Thread 1002 ...
1 Thread 1001 ...
And reconnect:
(gdb) disconnect
(gdb) tar rem ...
We end up with:
(gdb) info threads
3 Thread 1003 ...
2 Thread 1001 ...
* 1 Thread 1002 ...
Not a real big issue, but it's reasonably fixable, by having GDB
fetch/sync the thread list before fetching the status/'?', and then
using the status to select the right thread as current on the GDB
side. Holes in the thread numbers are squashed before/after
reconnection (e.g., 2,3,5 becomes 1,2,3), but the order is preserved,
which I think is both good, and good enough.
However (yes, there's more...), the previous GDB that was connected
might have had gdbserver running in non-stop mode, or could have left
gdbserver doing disconnected tracing (which also forces non-stop), and
if the new gdb/connection is in all-stop mode, we can end up with more
than one thread with a signal to report back to gdb. As we can only
report one thread/status (in the all-stop RSP variant; the non-stop
variant doesn't have this issue), we get to do what we do at every
other place we have this situation -- leave events we can't report
right now as pending, so that the next resume picks them up.
Note all this ammounts to a QoI change, within the existing framework.
There's really no RSP change here.
The only user visible change (other than that the signal is program is
stopped at isn't lost / is passed to the program), is in "info
program", that now can show the signal the program stopped for. Of
course, the next resume will respect the pass/nopass setting for the
signal in question. It'd be reasonable to have the initial connection
tell the user the program was stopped with a signal, similar to when
we load a core to debug, but I'm leaving that out for a future change.
I think we'll need to either change how handle_inferior_event & co
handle stop_soon, or maybe bypass them completely (like
fork-child.c:startup_inferior) for that.

since Epoch, and so added a Python pretty-printer, to print this
type in a more human-friendly way. For instance:
(gdb) print before
$1 = Thu Nov 14 02:22:23 2013 (
1384395743)
However, we've noticed that things stop working when this type is
embedded inside another record, and we try to print that record.
For instance, with the following declarations:
type Composite is record
Id : Integer;
T : Time_T;
end record;
Afternoon : Composite := (Id => 1, T => (Secs =>
1384395865));
(gdb) print afternoon
$2 = (id => 1, t => (secs =>
1384395865))
We expected instead:
(gdb) print afternoon
$2 = (id => 1, t => Thu Nov 14 02:24:25 2013 (
1384395865))
This patch fixes the problem by making sure that we try to print
each field via a call to val_print, rather than calling ada_val_print
directly. We need to go through val_print, as the val_print
handles all language-independent features such as calling the
pretty-printer, knowing that ada_val_print will get called eventually
if actual Ada-specific printing is required (which should be the
most common scenario).
And because val_print takes the language as parameter, we enhanced
the print_field_values and print_variant_part to also take a language.
As a bonus, this allows us to remove a couple of references to
current_language.

* ada-valprint.c (print_field_values): Add "language" parameter.

ada_print_floating: Remove use of statically sized buffer.
ada_print_floating declares a char buffer with a size that we're hoping
to always be large enough to hold any string representation of a float
value. But that's not really necessary, and also forces us to create
a small wrapper (ui_memcpy) to perform the extraction from a temporary
stream into this buffer. This patches fixes both issues by relying on
ui_file_xstrdup. This forces us to make a few adjustments that are
minor in nature, as we now need to defer the cleanup to the end of
the function.

Extract string-printing out of ada_val_print_array
This patch creates a new function called "ada_val_print_string"
whose code is directly extracted out of ada_val_print_array.
The extracted code is then replaced by a call to this new function,
followed by a "return". The return avoids the need for an "else"
branch, with the associated block nesting. The latter is not really
terrible in this case, but it seems more readable this way.

rewrite ada_val_print_ref to reduce if/else block nesting depth
The logic as currently implemented in this function was a little
difficult to follow, due to the nested of if/else conditions,
but most of the time, the "else" block was very simple. So this
patch re-organizes the code to use fewer levels of nesting by
using return statements, and writing the code as a sequence of
"if something simple, then handle it and return" blocks.
While touching this code, this patch changes the cryptic "???"
printed when trying to print a reference pointing to an undefined
type. This should only ever happen if the debugging information
was corrupted or improperly read. But in case that happens, we now
print "<ref to undefined type>" instead. This is more in line
with how we print other conditions such as optimized out pieces,
or synthetic pointers.

Remove call to gdb_flush at end of ada_val_print_1
I am not sure why this function was called in the first place, but
it disrupts the printing flow when in GDB/MI mode, ending the current
console stream output, and starting a new one. It's not clear whether,
with the code as currently written, the problem is actually visible
or only latent. But, it becomes visible when we replace one of the
"return" statements in the "switch" block just above by a "break"
statement (this is something I'd like to do, and what made me realize
the problem). With the gdb_flush call (after having replaced the
"return" statement as explained above), we get:
% gdb -q -i=mi ada_prg
(gdb)

&"print 1\n"
!! -> ~"$1 = 1"

[python] Add gdb.Type.name attribute.
Consider the following declarations:
typedef long our_time_t;
our_time_t current_time =

The purpose of this patch is to allow the use of a pretty-printer

it does not apply to integral types.
This patch extends the gdb.Type list of attributes to also include
the name of the type, thus allowing the sniffer to match against
that name. With that change, I was able to write a pretty-printer
