the proper test is SYMBOL_REFERENCES_LOCAL for cases where we take the

gdb configure updates
Now that the configury needed for the "common" and "target"
directories is in common.m4, some code in gdb's configure.ac is
redundant.
I ran this script after making an "ID" file using mkid:
sed -n 's/^.*\(HAVE_[A-Z0-9_]*\).*$/\1/p' config.in |
while read x; do
echo ===== $x
gid $x | egrep -v '^(testsuite|gnulib|common|target|gdbserver)/'
done
This finds all the spots using HAVE_ defines, and, more importantly,
makes it clear which defines aren't used in the main parts of gdb.
From this I came up with this patch to remove all the unused bits.
There are a few that are subtly used -- for example the configure
script sometimes checks internal configure cache variables, meaning
some checks cannot be removed.

introduce common.m4
It has bothered me for a while that files in common/ use macros
defined via autoconf checks, but rely on each configure.ac doing the
proper checks independently.
This patch introduces common/common.m4 which consolidates the checks
assumed by code in common.
The rule I propose is that if something is needed or used by common,
it should be checked for by common.m4. However, if the check is also
needed by gdb or gdbserver, then it should be duplicated there.
Built and regtested on x86-64 Fedora 18 (though this is hardly the
most strenuous case) and using the Fedora 18 mingw cross compilers. I

constify to_detach
This patch constifies the target_ops method to_detach.
This is a small cleanup, but also, I think, a bug-prevention fix,
since gdb already acts as if the "args" argument here was const.
In particular, top.c:quit_force calls kill_or_detach via
iterate_over_inferiors. kill_or_detach calls target_detach, passing
the same argument each time. So, if one of these methods was not
const-correct, then kill_or_detach would change its behavior in a
strange way.
I could not build every target I modified in this patch. I've
inspected them all by hand, though. Many targets do not use the
"args" parameter; a couple pass it to atoi; and a few pass it on to
the to_detach method of the target beneath. The only code that
required a real change was in linux-nat.c, and that only needed the
introduction of a temporary variable for const-correctness.

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.

fix some "exec" tests
A few tests run an inferior that execs some other program. The name
of this exec'd program is compiled in. These tests assume the current
test suite directory layout, but fail in parallel mode.
This patch fixes these tests by letting the .exp files pass in the
directory names at compile time.

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
file. The thinking here was that if a code section didn't use the toc
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
mostly from previous objects sharing the same toc. We lose if the
functions in question are called mostly from the current object or
following objects, and it's a good bet they will probably mostly be
called from the current object.
