Add support for building with -fsanitize=undefined.
- add configure option --enable-ubsan
- add __ubsan helpers (by Julian)
This requires gcc 4.9.2 or later. Not all platforms are supported, though.
With this change and VEX r3099 regression tests pass on amd64
with a valgrind compiled with -fsanitize=undefined.

Merge revisions 14255, 14293, and 14294 from the BUF_REMOVAL branch to trunk.
The functions VG_(get_filename) and VG_(get_filename_lineno) now return
a pointer to filename and directory name instead of copying them into
buffers passed in from the caller.
The returned strings are persistent as long as the DebugInfo to which
they belong is not discarded. The caller therefore needs to stash them
away as needed.
Function VG_(strncpy_safely) has been removed as it is no longer needed.

The attached patch cleanups the clo processing
of clo which are (or should be) 'enum set'.
* pub_tool_options.h : add new macrox VG_USET_CLO and VG_USETX_CLO to
parse an 'enum set' command line option (with or without "all" keyword).
* use VG_USET_CLO for existing enum set clo options:
memcheck --errors-for-leak-kinds, --show-leak-kinds, --leak-check-heuristics
coregrind --vgdb-stop-at
* change --sim-hints and --kernel-variants to enum set
(this allows to detect user typos: currently, a typo in a sim-hint
or kernel variant is silently ignored. Now, an error will be given
to the user)
* The 2 new sets (--sim-hints and --kernel-variants) should not make
use of the 'all' keyword => VG_(parse_enum_set) has a new argument
to enable/disable the use of the "all" keyword.
* The macros defining an 'all enum' set definition was duplicating
all enum values (so addition of a new enum value could easily
give a bug). Removing these macros as they are unused
(to the exception of the leak-kind set).
For this set, the 'all macro' has been replaced by an 'all function',
coded using parse_enum_set parsing the "all" keyword.

atoll() is a terrible function -- you can't do any error checking with it.
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.

Add a new module, m_seqmatch, which does very simple sequence (regexp)
matching, in the function VG_(generic_match). Patterns to be matched
against may contain only '*'-style wildcards (matches any number of
elements, we don't care what they are), '?' wildcards (matches exactly
one element, we don't care what it is) and literal elements.
It is totally abstractified, in the sense that the pattern and input
arrays may be arrays of anything. The caller provides enough
information so that VG_(generic_match) can step along both arrays, and
can ask the questions "is this pattern element a '*' ?", "is this
pattern element a '?' ?", and "does this pattern element match an
input element ?".
The existing function VG_(string_match) is reimplemented using
VG_(generic_match), although the ability to escape metacharacters in
the pattern string is removed -- I don't think it was ever used.
In m_errormgr, matching of suppression stacks (including wildcard
"..." lines) against error stacks is re-implemented using
VG_(generic_match).
Further detailed comments are in m_seqmatch.h and pub_tool_seqmatch.h.
A negative side effect is that VG_(string_match) will be much slower
than before, due to the abstractification. It may be necessary to
reimplement a specialised version later.

Add four 'strtoll' variants, which are like 'atoll' but let you detect if
the string converted wasn't entirely numeric. Using them for numeric
command-line options -- previously if you had a option "--foo=<n>", where
<n> is supposed to be an integer, then "--foo=blah" would be interpreted as
"--foo=0", because the "blah" would be converted to zero and the remaining
chars wouldn't be noticed.
Fixed an incorrect command-line option in two massif tests that this change
exposed.

was calling VG_(memcpy) a huge number of times, and to callgrind for
finding out who :-)

Defensive hacks to detect cases where V corrupts its own heap and/or

This commit merges in changes from branches/ASPACEM (specifically,
changes from r4341 through r4787 inclusive). That branch is now dead.
Please do not commit anything else to it.
For the most part the merge was not troublesome. The main areas of
uncertainty are:
- build system: I had to import by hand Makefile.core-AM_CPPFLAGS.am
and include it in a couple of places. Building etc seems to still
work, but I haven't tried building the documentation.
- syscall wrappers: Following analysis by Greg & Nick, a whole lot of
stuff was moved from -generic to -linux after the branch was created.
I think that is satisfactorily glued back together now.
- Regtests: although this appears to work, no .out files appear, which
is strange, and makes it hard to diagnose regtest failures. In
particular memcheck/tests/x86/scalar.stderr.exp remains in a
conflicted state.
- amd64 is broken (slightly), and ppc32 will be unbuildable. I'll
attend to the former shortly.

Final commit for the initial modularisation pass:
- Broke part of m_scheduler off into a new module m_threadstate. It
contains ThreadState, VG_(threads)[] and some basic operations on the
thread table. All simple stuff, the complex stuff stays in m_scheduler.
This avoids lots of circular dependencies between m_scheduler and other
modules.
- Managed to finally remove core.h and tool.h, double hurrah!
- Introduced pub_tool_basics.h and pub_core_basics.h, one of which is
include by every single C file.
- Lots of little cleanups and changes related to the above.
- I even did a small amount of documentation updating.

A major overhaul of all machinery to do with syscalls, but mostly of
the m_syscalls module. Fundamentally the aim of the overhaul is to
clean up the logic and abstractions surrounding syscalls in order that
we can cleanly support ppc32 and other new targets. Aims in detail:
* To further decouple the syscall PRE/POST wrappers from specifics of
how those values are stored on a given platform. The wrappers look
the same as they did before, mostly (eg, references to ARGn and
RES are unchanged), but now those macros refer to values in structs
SyscallArgs and SyscallStatus (see priv_types_n_macros.h).
* Complete overhaul of the driver logic for syscalls. The resulting
logic is algorithmically identical to what we had before, but is
more documented, and deals with moving arg/result data between
platform specific representations and the canonical forms in
structs SyscallArgs and SyscallStatus.
* Also as a result of this change, remove problems in the old logic
due to assignments of RES in PRE wrappers trashing the ARGs whilst
we still need to see them.
* Lots of other cleanups and documentation. There is extensive
commentary in syscalls-main.c.
The driver logic has been placed in its own file, syscalls-main.c.
New/deleted files in m_syscalls:
* syscalls.c is divided up into syscalls-main.c, containing driver
logic, and syscalls-generic.c, containing generic Unix wrappers.
* priv_syscalls.h is chopped up into priv_types_n_macros.h
and priv_syscalls-{generic,main}.h.
------------
All the above changes are in m_syscalls. However there is one
system-wide change as a result of all this.
The x86-linux assumption that syscall return values in the range -4095
.. -1 are errors and all others are values, has been done away with
everywhere. Instead there is a new basic type SysRes which holds a
system call result in a platform-neutral way.
Everywhere that previously an Int would have held a system call
result, there is now a SysRes in its place.
------------
Almost everything works on SuSE 9.1 (LinuxThreads) again. NPTL will
still be majorly broken; I will commit fixes shortly. AMD64 is also
totalled. I will get to that too.

Started modularising vg_mylibc. Put all the standalone stuff -- ie. not
relying on any other modules -- in m_libcbase.
Also converted the 'size' parameters to functions like VG_(memcpy) and
VG_(strncpy) from Int to SizeT, as they should be.
Also removed VG_(atoll16) and VG_(toupper), which weren't being used.
Also made VG_(atoll36) less flexible -- it now only does base-36 numbers
instead of any base in the range 2..36, since base-36 is the only one we
need. As part of that, I fixed a horrible bug in it which caused it to
return incorrect answers for any number containing the digits 'A'..'I'!
(Eg. for "A; it would return 17 instead of 10!)
Had to disable the assertions in VG_(string_match), since this module can't
see vg_assert, which wasn't ideal but also isn't a disaster.
