S390: Fix TDB regset recognition
When checking for the presence of the TDB regset, the current code
interprets ENODATA from PTRACE_GETREGSET as an indication that the TDB
regset *could* occur on this system, but the inferior stopped outside
a transaction. However, the Linux kernel actually reports ENODATA
even on systems without the transactional execution facility. Thus
the logic is now changed to check the TE field in the HWCAP as well.
This version also checks the existence of the TDB regset -- just to be
on the safe side when running on TE-enabled hardware with a kernel
that does not offer the TDB regset for some reason.

Perf test framework
This patch adds a basic framework to do performance testing for GDB.
perftest.py is about the test case, testresult.py is about test
results, and how are they saved. reporter.py is about how results
are reported (in what format). measure.py is about measuring the
execution of tests by a collection of measurements.
In V5:
- Simplify perftest.exp.
In V4:
- Rename MeasurementCPUTime to MeasurementCpuTime,
- Add 'pass' in empty method,
- Simplify string comparison in perftest.exp.
- Rename GDB_PERFORMANCE to GDB_PERFTEST_MODE and rename
GDB_PERFORMANCE_TIMEOUT to GDB_PERFTEST_TIMEOUT.
In V3, there are some changes,
- Add wall time measurement, cpu time measurement and vmsize
measurement.
- Rename SingleStatisticTestCase to TestCaseWithBasicMeasurements,
which measures cpu time, wall time, and memory (vmsize).
- GDB_PERFORMANCE=run|compile|both to control the mode of perf
testing.
- New GDB_PERFORMANCE_TIMEOUT to specify the timeout.
- Split proc prepare to proc compile and startup.
- Disable GC while doing measurements.
In V2, there are several changes to address Doug and Sanimir's
comments.
- Add copyright header and docstring in perftest/__init__.py
- Remove config.py.
- Fix docstring format.
- Rename classes "SingleVariable" to "SingleStatistic".
- Don't extend gdb.Function in class TestCase. Add a new method run
to run the test case so that we can pass parameters to test.
- Allow to customize whether to warm up and to append test log.
- Move time measurement into test harness. Add a new class
Measurement for a specific measurement and a new class Measure to
measure them for a given test case.
- A new class ResultFactory to create instances of TestResult.
- New file lib/perftest.exp, which is to do some preparations and
cleanups to simplify each *.exp file.
- Skip compilation step if GDB_PERFORMANCE_SKIP_COMPILE is set.

switch to fully parallel mode
This switches "make check" to fully parallel mode.
One primary issue facing full parallelization is the overhead of
"runtest". On my machine, if I "touch gdb.base/empty.exp", making a
new file, and then "time runtest.exp", it takes 0.08 seconds.
Multiply this by the 1008 (in my configuration) tests and you get ~80
seconds. This is the overhead that would theoretically be present if
all tests were run in parallel.
However, the problem isn't nearly as bad as this, for two reasons.
First, you must divide by the number of jobs, assuming perfect
parallelization -- reasonably true for small -j numbers, based on the
results I see.
Second, the current test suite parallelization approach bundles the
tests, largely by directory, but also splitting up gdb.base into two
halves.
I was curious to see how the current bundling played out in practice,
so I ran "make -j1 check RUNTEST='/bin/time runtest'". This invokes
the parallel mode (thus the bundling) and then shows the time taken by
each invocation of runtest.
Then, I ran "/bin/time make -j3 check". (See below about -j2.)
The time for the entire -j3 test run was the same as the time for
"gdb.base1". What this means is that gdb.base1 is currently the
time-limiting run, preventing further parallelization gains.
So, I reason, whatever overhead we see from full parallelization will
only be seen by "-j1" and "-j2".
I then tried a -j2 test run. This does take longer than a -j3 build,
meaning that the gdb.base1 job finishes and then proceeds to other
runtest invocations.
Finally I tried a -j2 test run with the appended patch.
This was 9% slower than the -j2 run without the patch.
I think that is a reasonable slowdown for what is probably a rare
case. I believe this patch will yield faster test results for all -j
values greater than 2. For -j3 on my machine, the test suite is a few
seconds faster; I didn't try any larger -j values.
For -j1, I went ahead and changed the Makefile so that, if no -j
option is given, then the "check-single" mode is used. You can still
use "make -j1 check" to get single-job parallel-mode, though of course
there's no good reason to do so.
This change is likely to speed up the plain "make check" scenario a
little as we will now bypass dg-extract-results.sh.
One drawback of this change is that "make -jN check" is now much more
verbose. I generally only look at the .sum and .log files, but
perhaps this will bother some.
Another interesting question is scalability of the result. The
slowest test, which limits the scalability, took 80.78 seconds. The
mean of the remaining tests is 1.08 seconds. (Note that this is just
a rough estimate, since there are still outliers.)
This means we can run 80.78 / 1.08 =~ 74 tests in the time available.
And, in this data set (slightly older than the above, but materially
the same) there were 948 tests. So, I think the current test suite
should scale ok up to about -j12.
We could improve this number if need be by breaking up the biggest
tests.

Simplify ppc64 code setting toc_off.
Every function has a nominal toc pointer value, even if it isn't used,
so set toc_off for every code section to the value used in that object

it could use the previous object file's toc pointer value. It can,
but doing so is only a gain if functions in that section are called

As discussed on the GDB ML[1], libc probes for longjmp were not being

This is trivially fixed by moving the 'if (!gdbarch_get_longjmp_target_p

infrun.c: use GDB_SIGNAL_0 when hidding signals, not GDB_SIGNAL_TRAP.
IMO, it doesn't make sense to map random syscall, fork, etc. events to
GDB_SIGNAL_TRAP, and possible have the debuggee see that trap. This
just seems conceptually wrong to me - these aren't real signals a
debuggee would ever see. In fact, when stopped for those events, on
Linux, the debuggee isn't in a signal-stop -- there's no way to
resume-and-deliver-signal at that point, for example. E.g., when

In all the above, I used 'signal SIGTRAP' to emulate 'handle SIGTRAP
pass'. As described in "keep_going", 'handle SIGTRAP pass' does have
its place:
/* Do not deliver GDB_SIGNAL_TRAP (except when the user
explicitly specifies that such a signal should be delivered
to the target program). Typically, that would occur when a
user is debugging a target monitor on a simulator: the target
monitor sets a breakpoint; the simulator encounters this
breakpoint and halts the simulation handing control to GDB;
GDB, noting that the stop address doesn't map to any known
breakpoint, returns control back to the simulator; the
simulator then delivers the hardware equivalent of a
GDB_SIGNAL_TRAP to the program being debugged. */
... and I've made use of that myself when implementing/debugging
stubs/monitors. But in these cases, treating these events as SIGTRAP
possibly injects signals in the debuggee they'd never see otherwise,
because you need to use ptrace to enable these special events, which
aren't real signals.
There's more. Take this bit of handle_inferior_event, where we
determine whether a real signal (TARGET_WAITKIND_STOPPED) was random
or not:
if (ecs->event_thread->suspend.stop_signal == GDB_SIGNAL_TRAP)
ecs->random_signal
= !((bpstat_explains_signal (ecs->event_thread->control.stop_bpstat,
GDB_SIGNAL_TRAP)
!= BPSTAT_SIGNAL_NO)
|| stopped_by_watchpoint
|| ecs->event_thread->control.trap_expected
|| (ecs->event_thread->control.step_range_end
&& (ecs->event_thread->control.step_resume_breakpoint

else
{
enum bpstat_signal_value sval;
sval = bpstat_explains_signal (ecs->event_thread->control.stop_bpstat,

ecs->event_thread->suspend.stop_signal = GDB_SIGNAL_TRAP;
bit is only reacheable for signals != GDB_SIGNAL_TRAP. AFAICS, sval
can only be BPSTAT_SIGNAL_HIDE if nothing in the bpstat returns
BPSTAT_SIGNAL_PASS. So that excludes a "catch signal" for the signal
in question in the bpstat. All other catchpoints that aren't based on
breakpoints behind the scenes call process_event_stop_test directly
(don't pass through here) (well, almost all: TARGET_WAITKIND_LOADED
does have a fall through, but only for STOP_QUIETLY or
STOP_QUIETLY_NO_SIGSTOP, which still return before this code is
reached). Catchpoints that are implemented as breakpoints behind the
scenes can only appear in the bpstat if the signal was GDB_SIGNAL_TRAP
(bkpt_breakpoint_hit returns false otherwise). So that leaves a
target reporting a hardware watchpoint hit with a signal other than
GDB_SIGNAL_TRAP. And even then it looks quite wrong to me to
magically convert the signal into a GDB_SIGNAL_TRAP here too -- if the
user has set SIGTRAP to "handle pass", the program will see a trap
that gdb invented, not one the program would ever see without gdb in
the picture.

Report overflow on PowerPC64 @h and @ha relocations.
This changes the behaviour of @h and @ha on PowerPC64 to report errors
on 32-bit overflow. The motivation for this change is that on
PowerPC64, most uses of @h and @ha modifiers and their corresponding
relocations are to build up 32-bit offsets. We'd like to know when
such offsets overflow. Only rarely do people use @h or @ha with the
high 32-bit modifiers to build a 64-bit constant. Those uses will now
need to use two new modifiers, @high and @higha, if the constant isn't
known at assembly time. For now, we won't report overflow at assembly
time..

relocations.

at least did the basic early checks that would lead to no such symbol
getting emitted. This in particular avoids emitting such a symbol in
the majority of (if not all) "ld -r" cases.
I hope my set of cross build tests caught all the test cases needing
adjustment - please forgive if I missed a few.

undef reg in gdb_curses.h
I tried to build gdb on the AIX machine in the GCC compile farm
(gcc111), but it failed in a couple of spots because gdb uses "reg" as
a variable name and the AIX <curses.h> defines "reg" to "register".
I saw that we already had a workaround for this lurking in utils.c, so
I just moved that to gdb_curses.h.
This fixed the problem on AIX and still builds on x86-64 Fedora 18.

Simplify REGISTRY cleanup usages
In registry.c:registry_clear_data, the registered data is iterated and
invoke each 'free' function with the data passed:
for (registration = data_registry->registrations, i = 0;
i < fields->num_data;
registration = registration->next, i++)
if (fields->data[i] != NULL && registration->data->free != NULL)
adaptor (registration->data->free, container, fields->data[i]);
we can see that data is passed to function 'free' and data is not NULL.
In each usage, we don't have to get the data again through key and
do NULL pointer checking. This patch is to simplify them.
