61448c507d We have a nice little collection of text files describing various high
level things.  But they're all over the place.  This commits moves
them all to the new docs/internals/ directory, and gives them 
a consistent naming scheme.

d8a24e8f50 Disable PIE by default (sorry Tom), even on PIE-enabled platforms. It
causes too much breakage.  PIE builds are still possible, but you have
to say --enable-pie to get them now.

fbf8653c8b Removed the remnants of the attempt at an ARM port, because it had
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.

816419fa9a No need to generate valgrind.h from valgrind.h.in. We can just use the
compiler symbols rather than our own symbols for the architectures (we
already were, more or less).  This simplifies the build, hurrah!

I also inverted the sense of the NVALGRIND ifdefs, to make them easier to
read, and fixed up some comments.

8c63e060a7 Restructured the include/ directory.
- All the subdirectories have gone: arm/, x86/, amd64/, linux/,         
  x86-linux/, amd64-linux/, arm-linux/.

- The following files were moved out of those directories into include/:

    amd64-linux/vki_arch.h            --> vki-amd64-linux.h
    x86-linux/vki_arch.h              --> vki-x86-linux.h
    x86-linux/vki_arch_posixtypes.h   --> vki_posixtypes-x86-linux.h
    linux/vki.h                       --> vki-linux.h
    amd64-linux/vki_arch_posixtypes.h --> vki_posixtypes-amd64-linux.h

- The following very small files were inlined into tool.h using the "#if
  defined(VGP_x86)..." technique:

    x86/tool_arch.h
    arm/tool_arch.h
    amd64/tool_arch.h

  The same technique was used twice to include the appropriate
  vki-$PLATFORM and vki-$OS files into tool.h.  

- The other files in those directories were removed.

- The build is much simpler, since we have 7(!) fewer Makefile.am files.
  Far fewer -I options are needed when compiling, too.

63901a5d88 Put all the system call stuff in a new module, m_syscalls. This
required moving a lot of stuff around.  I deleted
VG_(set_return_from_syscall_shadow)() and VG_(get_exit_status_shadow)(),
which screwed up the modularity and weren't being used and can be
simulated in other ways with a bit of care.

What are the chances that I've added and moved all the files correctly
in this commit, and not broken the amd64 port?

3f12fcbba8 Create a new module: ASpaceMgr, the address space manager. This
contains what was previously vg_memory.c and also vg_procselfmaps.c,
which is really just a helper for the address space manager.

This just moves code around and modularises it a bit.  It doesn't yet
resolve the circular dependencies between ASpaceMgr and various other
chunks of functionality (vg_malloc2, vg_symtab2).

signal frames.  This commit looks worse than it is -- really just a
load of moving-code-around.

This is the first multiple-implementation module, in that it has a
single interface (pub_core_sigframe.h) but multiple implementations,
depending on the os-cpu pair.  All the grotty details are hidden in
the implementation in m_sigframe/; callers need be aware only of the
interface.  Yay.

7a75a9f583 Overhauled the docs. Removed all the HTML files, put in XML files as
converted by Donna.  Hooked it into the build system so they are only
built when specifically asked for, and when doing "make dist".

They're not perfect;  in particular, there are the following problems:
- The plain-text FAQ should be built from FAQ.xml, but this is not
  currently done.  (The text FAQ has been left in for now.)

- The PS/PDF building doesn't work -- it fails with an incomprehensible
  error message which I haven't yet deciphered.

Nonetheless, I'm putting it in so others can see it.

10b4595add Added beginnings of an AMD64 port, so lots of new files and directories.
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.

7a04aed730 Introduced build variables VG_ARCH_ALL, VG_OS_ALL, and VG_PLATFORM_ALL,
which list all the arches/OSes/platforms supported.  These are used by
several newly added DIST_SUBDIRS automake commands, which specify that
although when you are building you only want to build for the current
arch/OS/platform, when you do 'make dist' you want every
arch/OS/platform to get included.

4399d9700f Added beginnings of an ARM port, to the point where it compiles. It does not
run, though.  There are lots of stubs to be filled in.  (The asm ones currently
just have "swi" in them, which seems to cause seg faults.) 

Also, some of the macros are decided dubious, especially:

  ARCH_* are bogus
  SYSCALL_RET is bogus
  PLATFORM_SET_SYSCALL_RESULT is bogus
  not sure about SET_SYSCALL_RETVAL
  FIRST_STACK_FRAME et al -- bogus?
  VG_MAX_JUMPS ?

And in stage2.lds, the 0x8048000 is almost certainly wrong


This required some tweakings of the core:
- some of the vki_*.h kernel types were fixed up

- had to disable the AM_PROG_CC_C_O macro in configure.in, because automake
  (autoconf?) didn't like it...

- some "#ifdef __x86__" guards were introduced, for nasty x86 things I don't
  yet know how to factor out (trampoline page muck, sysinfo page muck).

- fixed a minor stupidity in vg_proxylwp.c.

- moved the ptrace wrapper into the x86-linux part

- had to change the intercept mangling scheme, to use 'J' instead of '$' as the
  escape char because GCC didn't like '$'.  This is all very dubious, and only
  works because none of our intercepted symbols contains a 'J'.  To be fixed up
  ASAP.

d67d99a446 Arch-abstraction:
- Started overhauling the syscalls to account for different architectures;
  in particular, accounts for the fact that the __NR_foo syscall number
  often doesn't directly match with the sys_foo() function that implements the
  function in the Linux kernel.  So started introducing this indirection as
  needed.  Currently, only read() and write() have been done;  the transition
  will be staged, since doing all syscalls in one hit is a total pain.

  This will also pave the way for scalar syscall arg checking with Memcheck,
  now that it is clear what the prototypes of the relevant syscalls are.

- Removed support for 2.2 kernels in the configure test, after discussion with
  Julian.  If it causes major problems, we can consider reverting.

c4cf15dc21 Arch-abstraction:
- 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.
