Move basic perf-test output from perftest.log to perftest.sum.
This patch does two things.
1) Add support for multiple data points.
2) Move the "report" output from perftest.log to perftest.sum.
I want to record the raw data somewhere, and a bit of statistical analysis
(standard deviation left for another day), but I also don't want
it to clutter up the basic report.
This patch takes a cue from gdb.{sum,log} and does the same thing
with perftest.{sum,log}.
Ultimately, we'll probably want to emit raw data to csv files or some
such and then do post-processing passes on that.
gdb/testsuite/ChangeLog:
* lib/perftest/reporter.py (SUM_FILE_NAME): New global.
(LOG_FILE_NAME): New global.
(TextReporter.__init__): Initialize self.txt_sum.
(TextReporter.report): Add support for multiple data-points.
Move report to perftest.sum, put raw data in perftest.log.
(TextReporter.start): Open sum and log files.
(TextReporter.end): Close sum and log files.
* lib/perftest/testresult.py (SingleStatisticTestResult.record): Handle
multiple data-points.

Fix build error due to uninitialized variable warning
As of commit a5fdf78a4402341a0ae23a5ca8a63825e2b5286c, building GDB with
a GCC 4.1 host compiler fails with:
gdb/cp-namespace.c: In function 'cp_lookup_symbol_via_imports':
gdb/cp-namespace.c:482: warning: 'sym.block' may be used uninitialized in this function
Apparently, more recent compilers are able to deduce that no actual
uninitialized use of sym.block takes place, but GCC 4.1 isn't yet
able to do that.
Fixed by adding an explicit initalization.

* cp-namespace.c (cp_lookup_symbol_via_imports): Fix uninitialized
variable warning with some compilers.

Complete the previous commit (block_found refactoring)
The previous commit (Replace the block_found global with explicit
data-flow) lacks updates in a couple of files because it was not
tested building GDB with --enable-targets=all... but buildbots did.
This adds the appropriate simple updates to fix the build.

commit d12307c199dfdb9cad1ea79d2626224e705089a3
Author: Pierre-Marie de Rodat <derodat@adacore.com>

Replace the block_found global with explicit data-flow
As Pedro suggested on gdb-patches@ (see
https://sourceware.org/ml/gdb-patches/2015-05/msg00714.html), this
change makes symbol lookup functions return a structure that includes
both the symbol found and the block in which it was found. This makes
it possible to get rid of the block_found global variable and thus makes
block hunting explicit.

testsuite: tcl exec& -> 'kill -9 $pid' is racy (attach-many-short-lived-thread.exp races and others)
The buildbots show that attach-many-short-lived-thread.exp is racy.
But after staring at debug logs and playing with SystemTap scripts for
a (long) while, I figured out that neither GDB, nor the kernel nor the
test's program itself are at fault.
The problem is simply that the testsuite machinery is currently
subject to PID-reuse races. The attach-many-short-lived-threads.c
test program just happens to be much more susceptible to trigger this
race because threads and processes share the same number space on
Linux, and the test spawns many many short lived threads in
succession, thus enlarging the race window a lot.
Part of the problem is that several tests spawn processes with "exec&"
(in order to test the "attach" command) , and then at the end of the
test, to make sure things are cleaned up, issue a 'remote_spawn "kill
-p $testpid"'. Since with tcl's "exec&", tcl itself is responsible
for reaping the process's exit status, when we go kill the process,
testpid may have already exited _and_ its status may have (and often
has) been reaped already. Thus it can happen that another process
meanwhile reuses $testpid, and that "kill" command kills the wrong
process... Frequently, that happens to be
attach-many-short-lived-thread, but this explains other test's races
as well.
In the attach-many-short-lived-threads test, it sometimes manifests
like this:
(gdb) file /home/pedro/gdb/mygit/build/gdb/testsuite/gdb.threads/attach-many-short-lived-threads
Reading symbols from /home/pedro/gdb/mygit/build/gdb/testsuite/gdb.threads/attach-many-short-lived-threads...done.

Other times the process dies while the test is ongoing (the process is

(gdb) FAIL: gdb.threads/attach-many-short-lived-threads.exp: iter 2: reset timer in the inferior

And other times it dies just while we're detaching:

(gdb) PASS: gdb.threads/attach-many-short-lived-threads.exp: iter 2: print seconds_left
detach
Can't detach Thread 0x7fb13b7de700 (LWP 1842): No such process
(gdb) FAIL: gdb.threads/attach-many-short-lived-threads.exp: iter 2: detach
GDB mishandles the latter (it should ignore ESRCH while detaching just
like when continuing), but that's another story.
The fix here is to change spawn_wait_for_attach to use Expect's
'spawn' command instead of Tcl's 'exec&' to spawn programs, because
with spawn we control when to wait for/reap the process. That allows
killing the process by PID without being subject to pid-reuse races,
because even if the process is already dead, the kernel won't reuse
the process's PID until the zombie is reaped.
The other part of the problem lies in DejaGnu itself, unfortunately.
I have occasionally seen tests (attach-many-short-lived-threads
included, but not only that one) die with a random inexplicable
SIGTERM too, and that too is caused by the same reason, except that in
that case, the rogue SIGTERM is sent from this bit in DejaGnu's remote.exp:
exec sh -c "exec > /dev/null 2>&1 && (kill -2 $pgid || kill -2 $pid) && sleep 5 && (kill $pgid || kill $pid) && sleep 5 && (kill -9 $pgid || kill -9 $pid) &"
...
catch "wait -i $shell_id"
Even if the program exits promptly, that whole cascade of kills
carries on in the background, thus potentially killing the poor
process that manages to reuse $pid...
I sent a fix for that to the DejaGnu list:
http://lists.gnu.org/archive/html/dejagnu/2015-07/msg00000.html
With both patches in place, I haven't seen
attach-many-short-lived-threads.exp fail again.
Tested on x86_64 Fedora 20, native, gdbserver and extended-gdbserver.

Mostly trivial enum fixes
This is a patch I extracted from Pedro's C++ branch. It contains the
most trivial enum fixes, where an integer type/value was used instead
of the appropriate enum type/value. It fixes many C++ errors, since
in C++ you can't mix integers and enums implicitely.
Regardless of the C++ conversion, I think this is a good cleanup to make
use of the appropriate enum types.
Regression-tested on native x86_64.

All the "[Thread FOO] #NN stopped." above are bogus, as well as the
"Cannot remove breakpoints because program is no longer writable.",
which is a consequence.
The problem is that when we intercept a fork event, we should report
the event for the parent, only, and leave the child stopped, but not
report its stop event. GDB later decides whether to follow the parent
or the child. But because handle_extended_wait does not set the
child's last_status.kind to TARGET_WAITKIND_STOPPED, a
stop_all_threads/unstop_all_lwps sequence (e.g., from trying to access

PR threads/18600: Inferiors left around after fork+thread spawn
The new gdb.threads/fork-plus-threads.exp test exposes one more
problem. When one types "info inferiors" after running the program,
one see's a couple inferior left still, while there should only be
inferior #1 left. E.g.:
(gdb) info inferiors
Num Description Executable
4 process 8393 /home/pedro/bugs/src/test
2 process 8388 /home/pedro/bugs/src/test
* 1 <null> /home/pedro/bugs/src/test
(gdb) info threads
Calling prune_inferiors() manually at this point (from a top gdb) does
not remove them, because they still have inf->pid != 0 (while they
shouldn't). This suggests that we never mourned those inferiors.
Enabling logs (master + previous patch) we see:

{

if (debug_linux_nat)
fprintf_unfiltered (gdb_stdlog, "WL: %s exited.\n",
target_pid_to_str (lp->ptid));
}
}
That was the leader thread reporting an exit, meaning the whole
process is gone. So the problem is that this code doesn't understand
that an WIFEXITED status of the leader LWP should be reported to
infrun as process exit.

PR threads/18600: Threads left stopped after fork+thread spawn
When a program forks and another process start threads while gdb is
handling the fork event, newly created threads are left stuck stopped
by gdb, even though gdb presents them as "running", to the user.
This can be seen with the test added by this patch. The test has the
inferior fork a certain number of times and waits for all children to
exit. Each fork child spawns a number of threads that do nothing and
joins them immediately. Normally, the program should run unimpeded
(from the point of view of the user) and exit very quickly. Without
this fix, it doesn't because of some threads left stopped by gdb, so
inferior 1 never exits.
The program triggers when a new clone thread is found while inside the
linux_stop_and_wait_all_lwps call in linux-thread-db.c:
linux_stop_and_wait_all_lwps ();
ALL_LWPS (lp)
if (ptid_get_pid (lp->ptid) == pid)
thread_from_lwp (lp->ptid);
linux_unstop_all_lwps ();
Within linux_stop_and_wait_all_lwps, we reach
linux_handle_extended_wait with the "stopping" parameter set to 1, and
because of that we don't mark the new lwp as resumed. As consequence,
the subsequent resume_stopped_resumed_lwps, called from
linux_unstop_all_lwps, never resumes the new LWP.
There's lots of cruft in linux_handle_extended_wait that no longer
makes sense. On systems with CLONE events support, we don't rely on
libthread_db for thread listing anymore, so the code that preserves
stop_requested and the handling of last_resume_kind is all dead.
So the fix is to remove all that, and simply always mark the new LWP
as resumed, so that resume_stopped_resumed_lwps re-resumes it.

Remove isize output argument from fast_tracepoint_valid_at
This patch removes the isize output argument from the
fast_tracepoint_valid_at gdbarch hook. It was used to return the size
of the instruction that needs to be replaced when installing a fast
tracepoint. Instead of getting this value from the
fast_tracepoint_valid_at hook, we can call the gdb_insn_length function.
If we do not do this, then architectures which do not have a restriction
on where to install the fast tracepoint will send uninitialized memory
off to GDBserver. See remote_download_tracepoint:
~~~
int isize;
if (gdbarch_fast_tracepoint_valid_at (target_gdbarch (),
tpaddr, &isize, NULL))
xsnprintf (buf + strlen (buf), BUF_SIZE - strlen (buf), ":F%x",
isize);
~~~
The default implementation of fast_tracepoint_valid_at will not set
isize resulting in uninitialized memory being sent. Later on, GDBserver
could use this information to compute a jump offset.

* arch-utils.c (default_fast_tracepoint_valid_at): Remove unused
isize argument.

[AArch64] Rename boolean arguments in decoding functions
This patch cleans up the decoding functions using booleans when they can
decode two instructions. The boolean argument is used to know which of
the two instructions was decoded.
The instructions affected are BR/BLR, B/BL, CBZ/CBNZ and TBZ/TBNZ.
These arguments would be named after a named bit in the instruction
encoding, this patch renames them to 'is_XXX'. Furthermore, the
'unsigned' type would be used to describe a boolean while
aarch64_decode_cb would use 'int' (see the 'is64' argument). This patch
makes all booleans be 'int' and decoded bitfields be 'unsigned'.
gdb/ChangeLog:
* aarch64-tdep.c (decode_b): Rename link argument to is_bl.

(decode_br): Rename link argument to is_blr. Change its type to

MIPS ptrace build fixes
Since Pedro's ptrace cleanups, the MIPS buildbot compilation fails.
Code in MIPS native uses ptrace with 3 arguments, where ptrace requires
4. When looking at the definition of ptrace in
/usr/include/sys/ptrace.h, it shows that it takes a variable number of
arguments. The wrapper macro in nat/gdb_ptrace.h takes a fixed number
of arguments (4). That would explain why it used to work and stopped.
I am pushing this as obvious, tell me if there is any problem.
I built-tested this with a MIPS toolchain (ct-ng), but I don't have any
setup to test it. At least it should put back the buildbot builder in a
better shape.

PR record/18691: Fix fails in solib-precsave.exp
We see the following regressions in testing on x86_64-linux,
reverse-step^M
Cannot access memory at address 0x2aaaaaed26c0^M
(gdb) FAIL: gdb.reverse/solib-precsave.exp: reverse-step into solib function one
when GDB reverse step into a function, GDB wants to skip prologue so
it requests TARGET_OBJECT_CODE_MEMORY to read some code memory in
memory_xfer_partial_1. However in dcache_read_memory_partial, the object
becomes TARGET_OBJECT_MEMORY
return ops->to_xfer_partial (ops, TARGET_OBJECT_MEMORY, NULL,
myaddr, NULL, memaddr, len,
xfered_len);
in reverse debugging, ops->to_xfer_partial is record_full_core_xfer_partial
and it will return TARGET_XFER_E_IO because it can't find any records.
The test fails.
At this moment, the delegate relationship is like
dcache -> record-core -> core -> exec
and we want to GDB read memory across targets, which means if the
requested memory isn't found in record-core, GDB can read memory from
core, and exec even further if needed. I find raw_memory_xfer_partial
is exactly what I want.

Don't set gdb,noinferiorio on gdbserver boards

inferior output with "-i $inferior_spawn_id", we can remove this now,

Unbuffer all tests that rely on stdio
This forces all tests that rely on stdio to be unbuffered, like
interrupt.exp was adjusted in 6f98576f.
To recap, in some scenarios, GDB or GDBserver can be spawned with
input _not_ connected to a tty, and then tests that rely on stdio fail
with timeouts, because the inferior's stdout and stderr streams end up
fully buffered. Calling gdb_unbuffer_output forces output to be
unbuffered.

https://sourceware.org/ml/gdb-patches/2015-02/msg00819.html.
Tested on x86_64 Fedora 20, native, and against a remote gdbserver
board file that connects to the target with ssh, with and without -t
(create pty).

Adjust MI to $inferior_spawn_id
Rather than trying to determine where (which spawn id) the inferior
output comes out from, which depends on e.g., remote that supports
file i/o remote protocol extension, vs remote that sends inferior
output through a separate $inferior_spawn_id, vs native debugging,
which sends output through $gdb_spawn_id, vs native debugging with a
test that uses "separate-inferior-tty" (like mi-console.exp does),
always expect inferior output from both $inferior_spawn_id and
$gdb_spawn_id.
mi-console.exp itself already copes with different possible outputs in
a similar way:
# Combine both outputs in a single pattern.
set output "($semihosted_output|$native_output)"

Make gdb.base/dprintf.exp use gdb_test_stdio
This one needed a larger revamp. The issue is that the "info
breakpoints" test at the bottom of the file is broken on targets that
can do both server-side dprintf, and inferior I/O, because then
neither the breakpoint numbers match nor the "already hit N times"
output.
Address that by making the test restart gdb from scratch when
switching between dprintf styles. Test groups are factored into
procedures, and we now use with_test_prefix. While we're changing
test messages, lowercase a few test messages, and then while at it,
modernize a couple things here and there.

Uniquify test names from gdb.python/{py-objfile.exp,py-pp-registration.exp}
While running some regression tests, I noticed that the two Python
tests mentioned in the $SUBJECT contain non-unique names. This is a
violation of our guidelines:
<https://sourceware.org/gdb/wiki/GDBTestcaseCookbook#Make_sure_test_messages_are_unique>
And also makes things harder for BuildBot. So I hacked both testcases

Consider addressable memory unit size in various value functions
This patch updates various value handling functions to make them
consider the addressable memory unit size of the current architecture.
This allows to correctly extract and print values on architectures whose
addressable memory unit is not 8 bits.
The patch doesn't cover all the code that would ideally need to be
adjusted, only the code paths that we happen to use, plus a few obvious
ones. Specifically, those areas are not covered by this patch:
- Management of unavailable bits
- Bitfields
- C++ stuff

Fallout from "Reorder more powerpc64 sections for -z relro"
Commit 23283c1b changed the layout of some bss style sections on
powerpc64, but neglected to add a page gap before the third PT_LOAD
segment created by this reording. Without a page gap we get two
PT_LOAD headers that overlap by one page in memory. That shouldn't be
allowed because the dynamic loader will load garbage from the first
page of the last segment over the last page of the previous segment.

* elf.c (_bfd_elf_map_sections_to_segments): Do not make a new
segment for loaded sections after nonloaded sections if the
sections are on the same page.

them. Add $NOPIE_CFLAGS and $NOPIE_LDFLAGS to linker size tests if
needed.

gdb.mi/mi-pending.c: Return NULL instead of nothing in thread function
Using gcc 5.2 (maybe other versions as well), building mi-pending.c gives
these warnings:
./gdb.mi/mi-pending.c: In function ‘thread_func’:
./gdb.mi/mi-pending.c:34:5: warning: ‘return’ with no value, in function returning non-void
return;
^
./gdb.mi/mi-pending.c:38:5: warning: ‘return’ with no value, in function returning non-void
return;
^
gdb_compile_pthreads assumes that the build was successful only if there
is no output. These warnings therefore make gdb_compile_pthreads think
that the build failed, and the test doesn't run.
The easy fix is to replace the "return" with "return NULL". I am
pushing this as obvious.
gdb/testsuite/ChangeLog:
* gdb.mi/mi-pending.c (thread_func): Replace return with return
NULL.

Remove xfail in gdb.mi/mi-watch.exp
I noticed there was an unexpected pass in mi-watch.exp when running on
x86_64. Doing a bit of archeology shows that the xfail was added by
4a543da. This particular test failed on the MIPS architecture, which
the original contributor was working with. Here is the thread:
https://www.sourceware.org/ml/gdb-patches/2007-09/msg00151.html
Looking at the latest buildbot results for MIPS, it seems that it's also
an unexpected pass on that architecture. Therefore, I see no reason to
leave the xfail in place.
gdb/testsuite/ChangeLog:
* gdb.mi/mi-watch.exp (test_watchpoint_triggering): Remove xfail.

Have SIGTERM promptly quit GDB even when the dummy target is active
GDB currently does not promptly quit after receiving a SIGTERM while no
proper target is active. This is because in handle_sigterm we currently
look at target_can_async_p to determine whether to asynchronously quit
GDB using an async signal handler or to asynchronously quit using the
quit flag. However, target_can_async_p is always false under the dummy
target, so under this target we always use the quit flag and not the
async signal handler to signal that GDB should quit. So GDB won't quit
until a code path that checks the quit flag is executed.
To fix this issue, this patch makes the SIGTERM handler no longer
inspect target_can_async_p, and instead makes the handler
unconditionally set the quit flag _and_ mark the corresponding async
signal handler, so that if the target is async (or if it's the dummy
target) then we will likely quit through the async signal handler, and
if it's not async then we will likely quit through the quit flag. This
redundant approach is similar to how we handle SIGINT.
gdb/ChangeLog:
* event-top.c (handle_sigterm): Don't inspect
target_can_async_p. Always set the quit flag and always mark
the async signal handler.
gdb/testsuite/ChangeLog:
* gdb.base/gdb-sigterm-2.exp: New test.

remote.c: Make read_ptid return a null value when no thread id is found.
When using GDB to debug an RX target using the GDB remote protocol,
using a Renesas supplied debug agent, I encountered the following
assertion error:
thread.c:85: internal-error: inferior_thread: Assertion `tp' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Create a core file of GDB? (y or n) n
Command aborted.
This assertion error occurs due to the fact that the value associated
with inferior_ptid is not on the thread list.
The remote debug output (obtained with "set debug remote 1") is fairly
short, so I will include it up to the point where things go wrong -
which is somewhat before the assertion failure:

Sending packet: $Hc-1#09...Packet received: OK
Sending packet: $qC#b4...Packet received: QC not supported
Above is the trace starting from the invocation of "target remote"
through the call of get_current_thread() in remote_start_remote().
Below, I've pasted this line of code along with additional lines of
context. The test following the call is especially important to
understanding both the problem and my patch.
/* We have thread information; select the thread the target
says should be current. If we're reconnecting to a
multi-threaded program, this will ideally be the thread
that last reported an event before GDB disconnected. */
inferior_ptid = get_current_thread (wait_status);
if (ptid_equal (inferior_ptid, null_ptid))
{
/* Odd... The target was able to list threads, but not
tell us which thread was current (no "thread"
register in T stop reply?). Just pick the first
thread in the thread list then. */
inferior_ptid = thread_list->ptid;
}
}
Prior to getting to the code pasted above, remote_start_remote()
made a call to target_update_thread_list(). This corresponds to the
following lines from the above trace:
Sending packet: $qfThreadInfo#bb...Packet received: m1
Sending packet: $qsThreadInfo#c8...Packet received: l
Sending packet: $qAttached:a410#bf...Packet received: 0
Packet qAttached (query-attached) is supported
Once target_update_thread_list has completed, the thread list
contains a single entry: {pid = 42000, lwp = 1, tid = 0}.
remote_start_remote() then makes a call to set_continue_thread(),
accounting for this line of the trace:
Sending packet: $Hc-1#09...Packet received: OK
Finally, the call to get_current_thread() is responsible for the last
line of the trace that I provided above:
Sending packet: $qC#b4...Packet received: QC not supported
get_current_thread() calls stop_reply_extract_thread() with the wait
status. This returns null_ptid.
get_current_thread() then calls remote_current_thread with a null
inferior_ptid. After the calls to putpkt() and getpkt(), rs->buf[0]
is 'Q', so read_ptid() is called and its result is returned.
The buffer passed to read_ptid() is " not supported". read_ptid ultimately
returns a ptid of {pid = 4200, lwp = 0, tid = 0}.
However, this thread is not on the thread list. As noted earlier, the
call to target_update_thread_list() had placed {pid = 42000, lwp = 1,
tid = 0} on the list. This is the only thread in the list.
When these calls ultimately return to remote_start_remote(),
inferior_ptid gets set to {pid = 4200, lwp = 0, tid = 0}, which
(again) is not on the thread list.
It appears to me that the string " not supported" is coming from the
debug agent. If so, it should be fixed, but I don't see a reason to
not consult the thread list in order to place a valid thread id in
inferior_ptid.
This (consultation of the thread list) is what is done when
inferior_ptid is null_ptid:
if (ptid_equal (inferior_ptid, null_ptid))
{
/* Odd... The target was able to list threads, but not
tell us which thread was current (no "thread"
register in T stop reply?). Just pick the first
thread in the thread list then. */
inferior_ptid = thread_list->ptid;
}
My patch causes a null inferior_ptid to be returned by read_ptid when
no thread id is found in the response from the debug agent. This
return value ends up being returned by remote_current_thread() and
then by get_current_thread. The assignment then places this null
value into inferior_ptid. That, in turn, allows the ptid_equal test
(noted above) to fetch a valid thread from the thread list. I no
longer see the assertion failure due a good value (which is on the
thread list) being placed in inferior_ptid.
This patch also adds two log warnings that may be output when "set
debug remote 1" is used. When running against the Renesas debug agent
mentioned earlier, this is the relevant portion of the log output:
Sending packet: $qC#b4...Packet received: QC not supported
warning: garbage in qC reply
warning: couldn't determine remote current thread; picking first in list.

* remote.c (read_ptid): Return null_ptid when no thread id
is found.

This reverts commit 4a11f2065906976675808364ddbd1c0f77eea41f.
The initial import commit failed to retain local changes made to
readline's configure.in (and the commit message erroneously stated that
there were no local changes that needed to be reapplied). Also the
import caused a couple of build errors and a scattering of testsuite
regressions throughout many arches. It's probably better to start over
with this import, hopefully more carefully next time.

Don't build readline's shared libs by default
Since the sync to version 7.0-alpho, readline now by default builds
(unused) shared libraries alongside static libraries, whereas before it
only built static libraries. A couple of GDB buildbots were not happy
with this change:
http://gdb-build.sergiodj.net/builders/AIX-POWER7-plain/builds/240
http://gdb-build.sergiodj.net/builders/Fedora-i686/builds/1518
To get these buildbots building again, this patch alters readline's
configure.ac file to not build shared libraries by default, as was the
case with readline 6.2. A more permanent fix may be to alter the
top-level Makefile.def to pass --disable-shared to readline, or to
investigate why these building these shared libraries are giving the
buildbots trouble. (I think the proximate reason why the i686 buildbot
fails is because it passes CFLAGS=-m32 instead of CC="gcc -m32" to the
top-level configure script, and readline's linker commands don't inherit
CFLAGS. Not sure about the AIX failure.)
readline/ChangeLog.gdb:
* configure.ac: Default opt_shared_libs to no.
* configure: Regenerate.

Sync readline/ to version 7.0 alpha
This patch syncs our upstream copy of readline from version 6.2 to the
latest version, 7.0 alpha (released July 10 2015).
I essentially copied what was done the last time readline was synced,
when Jan updated to readline 6.2 in 2011:
http://sourceware.org/ml/gdb-patches/2011-05/msg00003.html
Procedure:
1. I extracted the readline-7.0-alpha tarball on top of readline/.
2. I deleted all the new files under doc/ that were deliberately omitted
before.
3. I regenerated readline/configure and readline/examples/rlfe/configure
using autoconf 2.64. No other configure files need regenerating.
4. I updated the function gdb_printable_part in completer.c with a
trivial change made to the readline function it is based off of,
printable_part in readline/complete.c. There is more work to be done in
completer.c to sync it with readline/complete.c, but it is non-trivial
and should probably be done separately anyway.
Local patches that had to be reapplied:
None. readline 7.0 alpha contains all of our local readline
patches.
New files in readline/:
colors.{c,h}
examples/{hist_erasedups,hist_purgecmd,rl-callbacktest,rlbasic}.c
parse-colors.{c,h}
readline.pc.in
configure.ac
Deleted files in readline/:
configure.in
Regressions:
After the sync there is one testsuite regression, the test
"signal SIGINT" in gdb.gdb/selftest.exp which now FAILs. Previously,
the readline 6.2 SIGINT handler would temporarily reinstall the
underlying application's SIGINT handler and immediately re-raise SIGINT
so that the orginal handler gets invoked. But now (since readline 6.3)
its SIGINT handler does not re-raise SIGINT or directly invoke the
original handler; it now sets a flag marking that SIGINT was raised, and
waits until readline explicitly has control to call the application's
SIGINT handler. Anyway, because SIGINT is no longer re-raised from
within readline's SIGINT handler, doing "signal SIGINT" with a stopped
inferior gdb process will no longer resume and then immediately stop the
process (since there is no 2nd SIGINT to immediately catch). Instead,
the inferior gdb process will now just print "Quit" and continue to run.
So with this commit, this particular test case is adjusted to reflect
this change in behavior (we now have to send a 2nd SIGINT manually to
stop it).
Aside from this one testsuite regression, I personally noticed no
regression in user-visible behavior. Though I only tested on x86_64
and on i686 Debian Stretch.
Getting this kind of change in at the start of the GDB 7.11 development
cycle will allow us to get a lot of passive testing from developers and
from bleeding-edge users.

Add gmonster-{1,2} perf testcases.
These testcases are mocks of real programs.
GDB doesn't care what the programs do, they just have to look
and/or behave like the real program.
These testcases exercise gdb when debugging really large programs.
E.g., gmonster-1 has 10,000 CUs, and gmonster-2 has 1000 shared libs
(which is actually a little small, 5000 would be more accurate).

Call gdb_exit before gdb_skip_xml_test on gdb.base/catch-syscall.exp

gdb.python/py-events.exp and normal_stop observers ordering
I have patches that:
1 - make the CLI print stop info from a normal_stop observer, like MI
does.
2 - happen to change the order in which the Python and CLI/TUI
normal_stop observers are installed.
With those in place, py-events.exp regresses like shown below [1],
because the Python stop events are output before CLI prints stop info,
instead of after, and the test doesn't expect that.
With the same Python hooks, the order in which MI and Python events is
emited today is already undefined, because MI also uses the
normal_stop observer for output. I see no reason that we should in
general define the order observers, interpreters and scripting
languages get their turn at being notified of these events. So this
patch makes the test cope with Python->CLI output order too.
Tested on x86_64 Fedora 20.

PR gdb/18717: internal error if non-leader thread exits process
If a non-leader thread exits the process while all other threads are
ptrace-stopped, native gdb fails an assertion. The test added by this
commit catches it:
/home/pedro/gdb/mygit/build/../src/gdb/linux-nat.c:3198: internal-error: linux_nat_filter_event: Assertion `lp->resumed' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
FAIL: gdb.threads/non-leader-exit-process.exp: program exits normally (GDB internal error)
The fix is just to remove the assertion.
With that out of the way, neither GDB not GDBserver handle this
perfectly though, so I'm adding a KFAIL:
(gdb) continue

C++: handle glibc's ptrace(enum __ptrace_request, ...)
Building in C++ mode issues ~40 warnings like this:
../../src/gdb/linux-nat.c: In function ‘int linux_handle_extended_wait(lwp_info*, int, int)’:
../../src/gdb/linux-nat.c:2016:51: warning: invalid conversion from ‘int’ to ‘__ptrace_request’ [-fpermissive]
ptrace (PTRACE_GETEVENTMSG, pid, 0, &new_pid);
The issue is that in glibc, ptrace's first parameter is an enum.
That's not a problem if we pick the PTRACE_XXX requests from
sys/ptrace.h, as those will be values of the corresponding enum.
However, we have fallback definitions for PTRACE_XXX symbols when the
system headers miss them (such as PTRACE_GETEVENTMSG above), and those
are plain integer constants. E.g., nat/linux-ptrace.h:
#define PTRACE_GETEVENTMSG 0x4201
One idea would be to fix this by defining those fallbacks like:
-#define PTRACE_GETEVENTMSG 0x4201
+#define PTRACE_GETEVENTMSG ((enum __ptrace_request) 0x4201)
However, while glibc's ptrace uses enum __ptrace_request for first
parameter:
extern long int ptrace (enum __ptrace_request __request, ...) __THROW;
other libc's, like e.g., Android's bionic do not -- in that case, the
first parameter is int:
long ptrace(int request, pid_t pid, void * addr, void * data);
So the fix I came up is to make configure/ptrace.m4 also detect the
type of the ptrace's first parameter and defin PTRACE_TYPE_ARG1, as
already does the for parameters 3-4, and then simply wrap ptrace with
a macro that casts the first argument to the detected type. (I'm
leaving adding a nicer wrapper for when we drop building in C).
While this adds the wrapper, GNU/Linux files won't use it until the
next patch, which makes all native GNU/Linux files include
gdb_ptrace.h.

Initialise target descrption after skipping extra traps for --wrapper
Nowadays, when --wrapper is used, GDBserver skips extra traps/stops
in the wrapper program, and stops at the first instruction of the
program to be debugged. However, GDBserver created target description
in the first stop of inferior, and the executable of the inferior
is the wrapper program rather than the program to be debugged. In
this way, the target description can be wrong if the architectures
of wrapper program and program to be debugged are different. This
is shown by some fails in gdb.server/wrapper.exp on buildbot.
We are testing i686-linux GDB (Fedora-i686) on an x86_64-linux box
(fedora-x86-64-4) in buildbot, such configuration causes fails in
gdb.server/wrapper.exp like this:
spawn /home/gdb-buildbot-2/fedora-x86-64-4/fedora-i686/build/gdb/testsuite/../../gdb/gdbserver/gdbserver --once --wrapper env TEST=1 -- :2346 /home/gdb-buildbot-2/fedora-x86-64-4/fedora-i686/build/gdb/testsuite/outputs/gdb.server/wrapper/wrapper
Process /home/gdb-buildbot-2/fedora-x86-64-4/fedora-i686/build/gdb/testsuite/outputs/gdb.server/wrapper/wrapper created; pid = 8795
Can't debug 64-bit process with 32-bit GDBserver
Exiting
target remote localhost:2346
localhost:2346: Connection timed out.
(gdb) FAIL: gdb.server/wrapper.exp: setting breakpoint at marker
See https://sourceware.org/ml/gdb-testers/2015-q3/msg01541.html
In this case, program to be debugged ("wrapper") is 32-bit but wrapper
program ("/usr/bin/env") is 64-bit, so GDBserver gets the 64-bit
target description instead of 32-bit.
The root cause of this problem is that GDBserver creates target
description too early, and the rationale of fix could be creating
target description once the GDBserver skips extra traps and inferior
stops at the first instruction of the program we want to debug. IOW,
when GDBserver skips extra traps, the inferior's tdesc is NULL, and
mywait and its callees shouldn't use inferior's tdesc, so in this
patch, we skip code that requires register access, see changes in
linux_resume_one_lwp_throw and need_step_over_p.
In linux_low_filter_event, if target description isn't initialised and
GDBserver attached the process, we create target description immediately,
because GDBserver don't have to skip extra traps for attach, IOW, it
makes no sense to use --attach and --wrapper together. Otherwise, the
process is launched by GDBserver, we keep the status pending, and return.
After GDBserver skipped extra traps in start_inferior, we call a
target_ops hook arch_setup to initialise target description there.

Set proc->priv->new_inferior out of linux_add_process
Nowadays, we set proc->priv->new_inferior to 1 inside linux_add_process,
and new_inferior is used as a flag to initialise target description later.
linux_add_process is used for the three cases, fork/vfork event
(handle_extended_wait), run the program (linux_create_inferior), and
attach to the process (linux_attach). In the first case, the child's
target description is copied from parent's, so we don't need to initialise
target description again later, which means we don't need to set
proc->priv->new_inferior to 1 in this case. For the rest of two cases,
we need this flag.
This patch move the code setting proc->priv->new_inferior to 1 inside
linux_add_process to linux_create_inferior and linux_attach. No
functionality is changed.

My patch series will affect the code starting inferior in GDBserver

start_inferior is used in different cases.

GBDserver receives 'R' packet, and this patch is to add a test

the test is to restart the program, to make sure GDBserver handles

Fix DT_MIPS_RLD_MAP_REL tag for n64 target and 32-bit host.
For the case of MIPS n64 target and 32-bit host, the computation of
the DT_MIPS_RLD_MAP_REL tag involves sdyn->output_section->vma +
sdyn->output_offset (64-bit) being added to b (32-bit host pointer),
so losing the high part and resulting in an incorrect
DT_MIPS_RLD_MAP_REL tag, and all dynamically linked glibc tests
failing for n64. This patch fixes this (spot-tested with glibc tests;
however, I don't have a self-contained testcase for this bug).
* elfxx-mips.c (_bfd_mips_elf_finish_dynamic_sections)
<DT_MIPS_RLD_MAP_REL>: Add target address to host address
difference, not to host pointer.

Fix crash when reading dummy CUs.
Dummy CUs are used by the incremental linker to pre-allocate space
in the output file. They have a DWARF header but no contents.
gdb/ChangeLog:
* dwarf2read.c (dwarf2_per_cu_data): Add comment.
(load_cu): Handle dummy CUs.
(dw2_do_instantiate_symtab, process_queuef): Ditto.
(dwarf2_fetch_die_loc_sect_off, dwarf2_fetch_constant_bytes): Ditto.
gdb/testsuite/ChangeLog:
* gdb.dwarf2/dw2-dummy-cu.S: New file.
* gdb.dwarf2/dw2-dummy-cu.exp: New file.
