f174930b23 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.

90e98b737e Updates to the rest of the debuginfo module to track directory names.
The only interesting part is a change of signature of
VG_(get_filename_linenum) so that callers can optionally request
directory info too.

eb2d0a7d06 Modularised assertions and panics in m_libcassert.
As part of this, killed the VG_STRINGIFY macro, which was used to expand
out names like "VG_(foo)" and "vgPlain_foo" in assertion failure
messages.  This is good since we actually want the "VG_(foo)" form used
in these messages.

09980587a9 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.

5bdf595e70 Modularised the profiling stuff as m_profile.c. It's much more
sensible now -- no vg_dummy_profile.c, no silly #including of
vg_profile.c from tools.  

Unfortunately, it still doesn't work, due to bad interactions
with signal handling that I don't understand.

247e241160 Modularised the core/tool interface ('details', 'needs' and VG_(tdict))
into a new module m_tooliface.  Pretty straightforward.  Touches a lot
of files because many files use this interface and so need to include
the headers for the new module.

that replace malloc with their own version.  Previously these two areas of

a08662c48c Big clean-up: changed the core/tool interface to be mediated entirely
through the VG_(tdict) function dictionary, rather than using TL_(foo)
functions.

This facilitated the following changes:

- Removed the "TL_" prefix, which is no longer needed.

- Removed the auto-generated files vg_toolint.[ch], which were no longer
  needed, which simplifies the build a great deal.  Their (greatly
  streamlined) contents went into core.h and vg_needs.h (and will soon
  go into a new module defining the core/tool interface).  
  
  This also meant that tool.h.base reverted to tool.h (so no more
  accidentally editing tool.h and not having the changes go into the
  repo, hooray!)  And gen_toolint.pl was removed.  And toolfuncs.def was
  removed.

- Removed VG_(missing_tool_func)(), no longer used.

- Bumped the core/tool interface major version number to 8.  And I
  killed the minor version number, which was never used.  The layout
  of the ToolInfo struct is such that this should not cause problems.

f1f707c7b2 This change reduces the number of calls to dlsym() when loading tools from a
lot to one.  This required two basic changes.

1. Tools are responsible for telling the tool about any functions they
provide that the tool may call.  This includes basic functions like
TL_(instrument)(), functions that assist core services such as
TL_(pp_Error)(), and malloc-replacement-related functions like
TL_(malloc)().  

2. Tools that replace malloc now specify the size of the heap block redzones
through an arg to the VG_(malloc_funcs)() function, rather than with a
variable VG_(vg_malloc_redzone_szB).

One consequence of these changes is that VG_(tool_init_dlsym)() no longer
needs to be generated by gen_toolint.pl.

There are a number of further improvements that could follow on from this one.
- Avoid the confusingly different definitions of the TL_() macro in the
  core vs. for tools.  Indeed, the functions provided by the tools now don't
  need to use the TL_() macro at all, as they can have arbitrary names.
- Remove a lot of the auto-generated stuff in vg_toolint.c and vg_toolint.h
  (indeed, it might be possible to not auto-generate these at all, which
  would be nice).
- The handling of VgToolInterface is currently split across vg_needs.c and
  vg_toolint.c, which isn't nice.

ee117f37d1 Reinstated Cachegrind. Seems to be working ok -- numbers compare pretty
well with those for the CVS version... the I1 accesses are noticeably
higher, but everything else is nearly the same.

There's some ugliness in spots, partly due to shortcomings with Vex.  And
CPUID auto-detection is currently disabled, because cpuid is disabled in
general.

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.

64af386b3e Simplified the way Cachegrind configures the caches; it was really
strange before.  Also aborting if any command-line-provided cache
configuration is unacceptable, rather than falling back on defaults;

necessary to get them compiling (eg. both of the TL_(instrument)()
functions were commented out and replaced with a stub).

This means that 'make dist' should more or less work again, which is
necessary for my playing with the XML documentation.
