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.

Memcheck is done, but any tool which generates IR helper calls will
need to be similarly adulterated.

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 ?

add a bunch of code to detect what the cpu can do at startup by
catching SIGILLs. Shame PPC doesn't offer any sane mechanism for
finding out what instruction subsets the CPU is capable of (a la
x86/amd64 cpuid).

snapshots on ppc32-linux in the presence of functions subject to
leaf-function optimisations.
At the same time, simplify the stack unwinding logic by basically
implementing it separately for each target. Having a single piece of
logic for amd64 and x86 was tenable, but merging ppc32 into it is too
confusing. So now there is an x86/amd64 unwinder and a ppc32
unwinder.
This requires plumbing a link-register value into
VG_(get_StackTrace2), and that in turn requires passing it around
several other stack-trace-related functions. Hence 7 changed files.

higher-order functions for traversing data structures. The higher-order
approach is too clumsy due to the lack of polymorphism and closures; you
have to use void* too much and it is more verbose than it should be.
Hence, I replaced all the uses of HT_first_match() and
HT_apply_to_all_nodes() with equivalent uses of the hashtable iterator.
Also replaced higher-order traversal functions for Memcheck's freed-list
and the thread stacks with iterators. That last change changes the
core/tool interface, so I've increased the version number.

bit of an ugly hack (see comments in m_machine.c) which is suitable
for merging into 3_0_BRANCH, but should be cleaned up once that's
done.

array at startup. This is used in m_transtab. However this info is
not yet fed to Vex, so it's still important to zero-out the auxv field
holding cache line size info passed to the client, so as to stop the
client's glibc using dcbz. This will be fixed.
Also get rid of a bunch more ppc32-specific vdso stuff in m_main that
doesn't need to be done. This now means ppc32-linux specifics in
m_main are only marginally intrusive than the x86-linux or amd64-linux
specifics in m_main.

things. These made sense when the arch/OS/platform-specific code was in
one module, but as that code got mixed in with generic code the boundary
between generic and non-generic blurred, and the distinction made less
sense. So let's get rid of them.

Plenty still to do, but simple programs like ls seem to run ok
Thanks, Paul, for having your ppc port of valgrind 2.4 to work from!

- 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.
