19bc251432 arm-linux: determine whether the host supports Neon by looking at our
AUXV at startup, rather than by trying to execute a Neon instruction
and seeing whether it SIGILLs.  Apparently the latter is not a
reliable way to ascertain the presence of usable Neon support.  Fixes
#249775.

3109865279 Merge in branches/DCAS.
This branch adds proper support for atomic instructions, proper in the
sense that the atomicity is preserved through the compilation
pipeline, and thus in the instrumented code.

These changes track the IR changes added by vex r1901.  They primarily
update the instrumentation functions in all tools to handle the
changes, with the exception of exp-ptrcheck, which needs some further
work in order to be able to run threaded code.

07045477ca Merge the DARWIN branch onto the trunk.
I tried using 'svn merge' to do the merge but it did a terrible job and
there were bazillions of conflicts.  So instead I just took the diff between
the branch and trunk  at r10155, applied the diff to the trunk, 'svn add'ed
the added files (no files needed to be 'svn remove'd) and committed.

5ad1dd61f9 Introduce a new type, PtrdiffT. Replace lots of uses of OffT (all those
that are memory offsets) with PtrdiffT;  OffT should only be used for file
sizes and offsets.

Change Off64T from a ULong to a Long, as it should be.  Replace some uses
of ULong in the address space manager with Off64T to match.

Also add a comment explaining the meanings of the basic types like Addr,
OffT, SizeT, etc.

Also fix the prototype for VG_(pread) -- the last arg is an OffT, not an
Int.

335992d8fc Merge all remaining changes from branches/PTRCHECK. These are some
relatively minor extensions to m_debuginfo, a major overhaul of
m_debuginfo/readdwarf3.c to get its space usage under control, and
changes throughout the system to enable heap-use profiling.

The majority of the merged changes were committed into
branches/PTRCHECK as the following revs: 8591 8595 8598 8599 8601 and
8161.

4cae5c3ed5 Merge branches/OTRACK_BY_INSTRUMENTATION into the trunk. This adds
support to Memcheck for tracking the origin of uninitialised values,
if you use the --track-origins=yes flag.

This currently causes some Memcheck regression tests to fail, because
they now print an extra line of advisory text in their output.  This
will be fixed.

The core-tool interface is slightly changed.  The version number for
the interface needs to be incremented.

ae8215b3ac Create a new module, m_vki, and move all knowledge about the kernel
interface, except for the syscall numbers, into that.  Mostly this
means moving include/vki-*.h to include/vki/vki-*.h.

include/pub_tool_basics.h previously dragged in the entire kernel
interface.  I've done away with that, so that modules which need to
see the kernel interface now have to include pub_{core,tool}_vki.h
explicitly.  This is why there are many modified .c files -- they have
all acquired an extra #include line.

This certainly breaks all platforms except x86.  Will fix shortly.

do_syscall_for_client_WRK() needed a bigger stack to avoid the linkage area.

always use dot_prefix for label calls

not wrapping assembly with
.section ".text"
...
.previous
 - ppc64 doesn't like it... seems we can't 'stack' more than one section to pop off with .previous ?
