commit message:
Steal some magic from FC3's valgrind-2.2.0 .spec file; it would be nice
to know if this works under other RPM-based distros (SuSE particularly).
I don't know much about .spec files, but this new version is much easier
to maintain because we don't have to list any filenames explicitly, and
no-one complained about it in 2.4.0, so let's go with it.

bit-rotted badly and was clogging up the code.
I put the useful remnants in docs/porting-to-ARM in case anyone ever
wants to try porting to ARM again.

overhaul of the thread support. Many things are now probably broken,
but at least with --tool=none, simple and not-so-simple threaded and
non-thread programs work.

It compiles, but aborts immediately if you try to run it.
I didn't include ldt.c; I'm not sure how the LDT is used on AMD64. It can be
added later if necessary.
While doing this, did some 64-bit cleanness fixes:
- Added necessary intermediate casts to ULong to avoid warnings when converting
ThreadId to void* and vice versa, in vg_scheduler.c.
- Fixed VALGRIND_NON_SIMD_CALL[0123] to use 'long' as the return type.
- Fixed VALGRIND_PRINTF{,BACKTRACE} to use unsigned longs instead of unsigned
ints, as needed.
- Converted some offsets in vg_symtab2.h from "Int" to "OffT".
- Made strlen, strncat, etc, use SizeT instead of 'unsigned int' for the length
parameter.
- Couple of other minor things.
I had to insert some "#ifdef __amd64__" and "#ifndef __amd64__" guards in
places. In particular, in vg_mylibc.c, some of our syscall wrappers aren't
appropriate for AMD64 because the syscall numbering is a bit different in
places. This difference will have to be abstracted out somehow.
Also rewrote the sys_fcntl and sys_fcntl64 wrappers, as required for AMD64.
Also moved the ipc wrapper into x86, since it's not applicable for
AMD64. However, it is applicable (I think) for ARM, so it would be nice
to work out a way to share syscall wrappers between some, but not all,
archs. Hmm. Also now using the real IPC constants rather than magic
numbers in the wrapper.
Other non-AMD64-related fixes:
- ARM: fixed syscall table by accounting for the fact that syscall
numbers don't start at 0, but rather at 0x900000.
- Converted a few places to use ThreadId instead of 'int' or 'Int' for
thread IDs.
- Added both AMD64 and ARM (which I'd forgotten) entries to valgrind.spec.in.
- Tweaked comments in various places.

- Added include/x86-linux/ and include/linux/ subdirectories, with Makefile.am
files.
- Overhauled the definitions of kernel types. include/vg_kerneliface.h is now
three files, include/linux/vki.h, include/x86-linux/vki_arch.h, and
include/x86-linux/vki_arch_posixtypes.h. These files separate the
common/Linux and x86/Linux parts cleanly. All code is copied verbatim from
the relevant kernel headers, except that VKI_/vki_ prefixes are added as
necessary to distinguish them from glibc types. (This is done consistently,
unlike previously when some types did not have the prefixes.)
All code is clearly marked to show which particular header file it came from,
and the Linux version used. (I used 2.6.8.1, the most recent stable release,
for all of them.)
A few of the types changed; this is because they changed between the older
versions of Linux and the current 2.6.8.1. I checked that all these changes
were ok with respect to backwards compatibility for our purposes.
- vg_unsafe.h has been removed; we are no longer including any kernel headers,
as we have our own copies for everything. This is because installed kernel
headers are not reliable, and often cause compilation problems. (bug
#92420 is a recent example)
- Removed some no-longer-needed header-presence tests from configure.in.
- Some code in the rest of Valgrind was changed to account for some slight
changes in the names of our VKI_/vki_ kernel constants and types.
- Updated README_MISSING_SYSCALL_OR_IOCTL accordingly.
- Fixed off-by-one error with VKI_GDT_ENTRY_TLS_MAX (merged from stable branch)
The end result is that the kernel types situation should be much clearer, and
similar files can be created relatively easily for other architectures as
necessary.

- Added include/x86/: contains tool_arch.h, Makefile.am, .cvsignore.
- Added coregrind/x86/state.c. Contains some arch-specific code for dealing
with x86 registers -- eg. setting up the baseBlock, loading/saving the whole
register state. It is compiled into coregrind/x86/libarch.a and linked via
${VG_ARCH} with the core.
Relatedly, also added coregrind/x86/{core_arch.h,core_arch_asm.h}.
- Correspondingly abstracted the register state out of ThreadState. This
affected every place that touches registers, and there are a lot of them.
(Eventually all the register touching should be abstracted out in an
arch-neutral way, but not yet; one step at a time.)
- Added some declarations about register loading/saving functions to core.h;
all architectures will have to provide these functions.
- Rejigged the build system so that the arch-specific stuff is all done via
${VG_ARCH}, rather than naming e.g. x86/ directly. Appropriate -I arguments
are used so that all the headers are found, etc.

Valgrind's dependency on the dynamic linker for getting started, and
instead takes things into its own hands.
This checkin doesn't add much in the way of new functionality, but it
is the basis for all future work on Valgrind. It allows us much more
flexibility in implementation, and well as increasing the reliability
of Valgrind by protecting it more from its clients.
This patch requires some changes to tools to update them to the changes
in the tool API, but they are straightforward. See the posting "Heads
up: Full Virtualization" on valgrind-developers for a more complete
description of this change and its effects on you.

in it, much of it from 1.0.X days. Did it in such a way that if it doesn't get
touched (and it undoubtedly won't) it won't really go out of date, eg. by
removing temporary details like version numbers, dates, details of specific
software incompatibilities. It's much better to be vague but correct, than
precise but incorrect; having incorrect info in a file as important as the
README is bad. Also removed the README_KDE3_FOLKS file because it's pretty
redundant now. Also added some changes that had been made in the stable branch
but not the HEAD.
Did similar, but smaller changes to README_DEVELOPERS and README_PACKAGERS.
Also updated the valgrind.spec.in file to use the new, post-1.0.X description
in the README.
Also fixed a minor omission in Addrcheck's docs.

installed, as it was silly since the reg tests themselves aren't installed.
Updated the "make regtest" target to use the uninstalled version in tests/.
Also, vg_regtest now no longer uses the installed version of Valgrind to do the
testing, but instead coregrind/valgrind. This means that you don't have to do
make install with your buggy changes before running the regtests on them :)
I even updated the RPM package .spec file!
Thanks to Dirk M�ller for the suggestion.

otherwise rpm on RH9 will complain that these files are in the payload area,
but not saved to the rpm.

Added cachegrind and vg_annotate to the spec file, as suggested by
