Move memcheck/mc_replace_strmem.c to shared/vg_replace_strmem.c and
add several intercepts for SSE-variants. Include that source file from
drd/drd_strmem_intercepts.c, helgrind/hg_intercepts.c and
memcheck/mc_replace_strmem.c.
Merge memcheck/tests/filter_memcpy into tests/filter_stderr_basic.

are not against the grain.
Wrap this script together with 'check_makefile_consistency' into
'post_regtest_checks' and invoke that from the toplevel Makefile. So we can
easily add new checkers in the future.
Add a new make target 'post-regtest-checks' to just run those checks
and nothing else.

(1) Detect availability of pthread_setname_np. Ignore testcases
memcheck/tests/threadname[_xml] if not available.
(2) Enable _GNU_SOURCE to avold compiler warnings.
(3) In threadname_xml filter out stackframes referring to system
libraries. Added tests/filter_xml_frames to do that.
(4) Adjust .exp files as needed
(5) Do not ship stdout.exp for memcheck/tests/threadname[_xml].

As this file is now detecting mips64/Cavium boards, we are renaming it to
reflect that. The functional change is that mips_features now can detect
Cavium board and allow Cavium-specific tests to be run.

The IBM Power ISA 2.07 has been published on power.org, and IBM's new POWER8
processor is under development to implement that ISA. This patch provides
initial runtime and testsuite support for running Valgrind on POWER8 systems
running a soon-to-be released Linux distribution. This Linux distro will
include a POWER8-tuned libc that uses a subset of the new instructions from
ISA 2.07. Since virtually all applications link with libc, it would be
impossible to run an application under Valgrind on this distro without adding
support for these new instructions to Valgrind, so that's the intent of this
patch. Note that applications built on this distro will *not* employ new POWER8
instructions by default. There are roughly 150 new instructions in the Power
ISA 2.07, including hardware transaction management (HTM). Support for these
new instructions (modulo the subset included in this bug) will be added to
Valgrind in a phased approach, similar to what we did for Power ISA 2.06.

* perf/vg_perf:
Similarly to tests/vg_regtest, perf/vg_perf now accepts the 3
optional arguments:
--outer-valgrind
--outer-tool
--outer-args
This allows easy analysis or comparison of performance between
different Valgrind versions (e.g. using callgrind, or cachegrind/cg_diff).
* See README_DEVELOPERS for more details.
* vg_regtest modified so as to use the 'in-place' build of inner, rather
than the installed version.
* added option --smc-check=all-non-file to vg_perf and vg_regtest
outer default arguments (needed when evaluating a Valgrind which does
translation chaining).

A '3 lines how to':
perl tests/vg_regtest --outer-valgrind=../trunk_untouched/install/bin/valgrind --all
(the outer results for a test xxx is in xxx.outer.log)
To run with another tool (e.g. drd), add the argument --outer-tool=drd
Still to do/things to improve:
* Most (inner) tests are successful when running under an outer
memcheck. Need to analyse the reasons of remaining failures.
* The memcheck annotations in m_mallocfree.c can be improved:
- A superblock is marked 'undefined', it should rather be marked
'no access'.
- When a free block is splitted, the remaining free block is
not made 'no access'. Instead, it is made 'undefined'.
=> this decreases the chance to find bugs.
=> this is not very efficient (e.g. the rest of a superblock
is often marked undefined repetitively).
Similarly, the free block created by VG_(arena_memalign)
is marked 'undefined'. 'No access' would be preferrable.
- mkInuseBlock marks the new block as undefined. This is probably
not needed, as VALGRIND_MALLOCLIKE_BLOCK will do it already.
- VG_(arena_malloc) should give the requested size to
VALGRIND_MALLOCLIKE_BLOCK, not the malloc usable size,
as this decreases the chance to find buffer overrun bugs.
But giving the requested size is tricky (see comments in
the code).
* need to do memcheck annotations in m_poolalloc.c
so as to allow leak checking for pool allocated elements.
* vg_regtest.in
- should analyse the results of the outer and should
produce a separate result for the tests for which
the outer detects an error or a memory leak or ...
Changes done:
README_DEVELOPERS: document the new outer/inner features.
manual-core.xml: document the new sim-hint no-inner-prefix
tests/outer_inner.supp: new file, containing the suppressions for inner.
vg_regtest.in: implement new args --outer-valgrind, --outer-tool, --outer-args.
m_mallocfree.c: annotations for memcheck.
m_libcprint.c: handle the new sim-hint no-inner-prefix
m_main.c: do an (early) parse of --sim-hints

and update exp files accordingly. This works well for x86
and all testcases pass on my machine.
New file filter_memcheck to do the work.
There is a bit of a ripple here as filter_memcheck requires
command line arguments to be passed in. So all users of
filter_memcheck (direct or indirect) were updated as well.
filter_stderr was simplified as was filter_libc.

bucket. Instead of removing what we don't want to see in a backtrace
(e.g. path segments through libc and libpthread), we simply keep what
we do want to see. That way .exp files can be generic.
We need to make sure that GCC inlining does not get in the way. So all
the ..._WRK function in hg_intercepts.c are attributed as noinline.
The backtrace filtering is done in the new filter_helgrind script.
filter_stderr is simplified quite a bit.

on various platforms:
* In all gdbserver_tests using gdb:
Made a more general way to remove the initial start message.
* tests using threads burning cpu modified to have only 1 thread.
This makes them independent of the scheduler fairness.
* filter_gdb and filter_vgdb enhanced to anonymise
some debian 6.0/ppc specific things
some s390x/gdb 7.0, gdb 7.1 specific things
* vgdb.c: added an #include <linux/ptrace.h> to fix compilation
on s390x fedora and suse. (Christian Boerntrager)
* fixed a bug in valgrind-low.c debug log :
when a register size is 0, its image cannot be output (and register
should not be transferred).
* added a parameter --keep-unfiltered to vg_regtest.in
This will make it easier to update filter_gdb:
in case gdbserver_tests are failing due to "artificial"
differences to be filtered, re-run the tests using:
perl tests/vg_regtest --keep-unfiltered gdbserver_tests
Then a tar file with all the *.out in gdbserver_tests
will allow me to better/faster update the filter_gdb.
* made a better detection of a working PTRACE_GETREGS at compile time
and/or at run-time.
This is the patch on bug 214909 comment 69.
