1bd2f0baf1 remove unused gdbserver configury
This updates gdbserver's configure.ac to remove checks that aren't
directly needed by gdbserver.

a18d8f10c0 fix a comment in configure.ac
My grepping around showed that HAVE_MULTIPLE_PROC_FDS is only ever
mentioned in a comment in configure.ac.  Since the macro is long dead,
let's remove the last mention.

9467110bae 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.

6970667963 use gdb_string.h in m32c-tdep.c
m32c-tdep.c is the last user of HAVE_STRING_H in gdb proper.  It
really ought to be using gdb_string.h instead, as the rest of gdb
does.

3266f10be2 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
also examined the config.in diffs to ensure that symbols did not go
missing.

52554a0e32 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.

fa4d0c4081 Remove varobj_language_string, languages and varobj_languages
This patch does some cleanups, removing some language-related stuff.
Note that mi_cmd_var_info_expression uses varobj_language_string,
which is redundant, because we can get language name from
lang->la_natural_name.

varobj_language_string doesn't have "Ada", which looks like a bug to
me.  With this patch applied, this problem doesn't exist, because the
language name is got from the same place (field la_natural_name).

Hi,
When I add another name of language, I find field 'la_name' can be
'const char *'.  This patch is to constify it.

6682d9595e 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.

b9502d3fd7 gdb/dwarf2read.c: Sanity check DW_AT_sibling values.
When reading objects with corrupt debug information it is possible that
the sibling chain can form a loop, which leads to an infinite loop and
memory exhaustion.

Avoid this situation by disregarding and DW_AT_sibling values that point
to a lower address than the current entry.

6dbb67982c Test on solib load and unload
This patch is to add a test case to on the performance of GDB handling
load and unload of shared library.

In V4:

 - Handle malloc and dlopen failure,
 - Document test parameters.

In V3, there are some changes,

 - Adapt to perf test framework changes.
 - Measure load and unload separately.

In V2, there are some changes,

 - A new proc gdb_produce_source to produce source files.  I tried to
   move all source file generation code out of solib.exp, but
   compilation step still needs to know the generated file names.  I
   have to hard-code the file names in compilation step, which is not
   good to me, so I give up on this moving.
 - SOLIB_NUMBER -> SOLIB_COUNT
 - New variable SOLIB_DLCLOSE_REVERSED_ORDER to control the order of
   iterating a list of shared libs to dlclose them.
 - New variable GDB_PERFORMANCE to enable these perf test cases.
 - Remove dlsym call in solib.c.
 - Update solib.py for the updated framework.

gdb/testsuite/

	* lib/gdb.exp (gdb_produce_source): New procedure.
	* gdb.perf/solib.c: New.
	* gdb.perf/solib.exp: New.
	* gdb.perf/solib.py: New.

f27a123653 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.
