- Update the xml1 .exp files accordingly (getting rid of one which is no
longer necessary).
- Update origin4-many.stderr.exp accordingly.
- Update the handling of scalar_exit_group accordingly.

traces, and a few other unreliable pieces. This allowed most of the tests
to be reduced to a single .stderr.exp file. It also means that all Helgrind
tests succeed on my AMD64/Linux box when configured with --enable-only32bit,
whereas previously 20 of them failed.
Also tweaked a couple non-Helgrind filters a tiny bit.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@9389
--enable-only32bit builds on my Ubuntu box:
- For all tests, replace all operator new/new[]/delete/delete[] variants
with a common form, eg. "...operator new...". This makes
exp-ptrcheck/tests/ccc and memcheck/tests/mismatches pass.
- For Helgrind tests, replace all libpthread paths with "/...libpthread...",
as is done for libc paths. This avoids problems when /lib32/libpthread.so
is the path. No extra tests pass, but many of them get a lot closer to
passing.

- It heavily refactors the code: uses better names for things, splits up
complex functions that behaved very differently depending on how they were
called, removes some redundancies, and generally makes it much simpler and
easier to follow.
- It adds lots of comments, both inline, and also a big explanatory one at
the top which makes it clear exactly how the leak checker works and also
exactly what is meant by definite, possible, and indirect leaks. It also
has some ideas for future improvements.
- All tabs have been converted to spaces.
It also improves the functionality:
- Previously if you did --leak-check=summary, indirect and suppressed
blocks were counted as definite leaks. Now they are done properly, and so
the summary results from --leak-check=summary match those from
--leak-check=yes.
- Previously, some possibly reachable blocks were miscategorised as
definitely reachable, because only the pointer to the block itself was
considered, not any preceding pointers in the chain. This is now fixed.
- Added memcheck/tests/leak-cases, which fully tests all the possible
combinations of directly/indirectly reachable and possibly/definitely
reachable.
And it improves the manual quite a bit, and the FAQ a little bit.
This doesn't fix the leak checker to handle MALLOCLIKE_BLOCK works that have
been taken from within malloc'd blocks, but I think I know how to do it and
hope to do so in a subsequent commit.
It also changes all instances of "<constant>memcheck</constant>" in the
Memcheck manual to "Memcheck", for consistency and because "Memcheck" is
easier to write. There's one similar case for DRD but I didn't change that.

- by vg_regtest for determining if a directory name matches an architecture;
- by various .vgtest files for detecting x86/AMD64 features.
This commit splits it in two for the two different purposes, which makes
things clearer.
Specific changes
- Moved the x86/AMD64 feature detection stuff out of arch_test.c, and
into the new x86_amd64_feature.c. Updated the relevant .vgtest files for
the change.
- In vg_regtest, now a prereq command must return 0 (prereq satisfied) or 1
(prereq not satisfied). Anything else makes vg_regtest abort. This
makes obvious any problems with prereq tests rather than just making the
tests skip innocuously. (We previously had exactly such a problem on the
DARWIN branch; the x86 feature detection tests caused segfaults so the
tests were incorrectly skipped. This change will catch any similar future
problem.)
- Changed os_test from a script to a C program, matching cpu_test.
- Removed some unintentional darwin stuff from platform_test.

Remove VG_(strcmp_ws) and VG_(strncmp_ws); they're no longer needed by CLO
handling, and they're not much use elsewhere.

longer valid, as the comment indicates. Furthermore it mmaps arbitrary bits
of address space and so is horribly unportable, and doesn't work on Darwin.

Some of our option processing code uses it. This means that eg.
'--log-fd=9xxx' logs to fd 9, and '--log-fd=blahblahblah' logs to 0 (because
atoll() returns 0 if the string doesn't contain a number!)
It turns out that most of our option processing uses VG_(strtoll*) instead
of VG_(atoll). The reason that not all of it does is that the
option-processing macros are underpowered -- they currently work well if you
just want to assign the value to a variable, eg:
VG_BOOL_CLO(arg, "--heap", clo_heap)
else VG_BOOL_CLO(arg, "--stacks", clo_stacks)
else VG_NUM_CLO(arg, "--heap-admin", clo_heap_admin)
else VG_NUM_CLO(arg, "--depth", clo_depth)
(This works because they are actually an if-statement, but it looks odd.)
VG_NUM_CLO uses VG_(stroll10). But if you want to do any checking or
processing, you can't use those macros, leading to code like this:
else if (VG_CLO_STREQN(9, arg, "--log-fd=")) {
log_to = VgLogTo_Fd;
VG_(clo_log_name) = NULL;
tmp_log_fd = (Int)VG_(atoll)(&arg[9]);
}
So this commit:
- Improves the *_CLO_* macros so that they can be used in all circumstances.
They're now just expressions (albeit ones with side-effects, setting the
named variable appropriately). Thus they can be used as if-conditions,
and any post-checking or processing can occur in the then-statement. And
malformed numeric arguments (eg. --log-fd=foo) aren't accepted. This also
means you don't have to specify the lengths of any option strings anywhere
(eg. the 9 in the --log-fd example above). The use of a wrong number
caused at least one bug, in Massif.
- Updates all places where the macros were used.
- Updates Helgrind to use the *_CLO_* macros (it didn't use them).
- Updates Callgrind to use the *_CLO_* macros (it didn't use them), except
for the more esoteric option names (those with numbers in the option
name). This allowed getUInt() and getUWord() to be removed.
- Improves the cache option parsing in Cachegrind and Callgrind -- now uses
VG_(strtoll10)(), detects overflow, and is shorter.
- Uses INT instead of NUM in the macro names, to distinguish better vs. the
DBL macro.
- Removes VG_(atoll*) and the few remaining uses -- they're wretched
functions and VG_(strtoll*) should be used instead.
- Adds the VG_STREQN macro.
- Changes VG_BINT_CLO and VG_BHEX_CLO to abort if the given value is outside
the range -- the current silent truncation is likely to cause confusion as
much as anything.

built. This worked fine on the x86/Linux and AMD64/Linux but broke
ppc*/Linux. This commit fixes the problem. Thanks to Bart for spotting it.

- Rename 'oset_test' as 'unit_oset' to make its meaning more clear.
- Remove VG_(atoll36), VG_(strtoll8)() and VG_(strtoll36)(); they're not
used and so untested, but easy to crib from similar functions if they need
to be added again later.

- Created Makefile.tool-tests.am, put standard AM_CFLAGS et al for tests in
it.
- A number of tests are shared between Helgrind and DRD. They used to be
built in both directories. Now they are only built in helgrind/tests/,
and the DRD .vgtest files just point to the executable in helgrind/tests/.
Most of these (about 30) had the source files in helgrind/tests/; I moved
the three that were in drd/tests/ into helgrind/tests/ for consistency.
- Fixed rwlock_test, which was failing to run due to a wrong name in the
.vgtest file.
- Removed remnants of unused 'hello' test for Memcheck.
- Avoided redundant flag specification in various places, esp.
memcheck/tests/Makefile.am.
- Removed unnecessary _AIX guards in some Linux-only tests.

be replaced if malloc() et al are replaced by a tool. This is because
different tools implement the function in different ways.
Add an appropriate malloc_usable_size() replacement to each of Memcheck,
Helgrind, DRD, Ptrcheck, Massif.
Update memcheck/tests/malloc_usable and add massif/tests/malloc_usable.
Merged from the DARWIN branch.

I changed it to just filter the entire stack trace out for these errors (both
normal and XML cases). The syscall name is still present in the error
string. This allows a one or more alternative expected output files to be
removed for several tests, which is A Very Good Thing.
Also, I killed filter_test_paths because it was weird and clumsy and the
above change obviated most of its use and the remaining effects could be
achieved in other ways.
Also, I fixed up the scalar* tests a little and they now pass on my machine,
(and hopefully at least some other machines) for the first time ever!
