82e0033fdd Switched back from dynamic detection of whether the proc filesystem
is mounted to compile-time logic in order to minimize the differences
in behavior with Valgrind version 3.5.0.

772166c146 Renamed the function VG_(have_proc_filesystem)() into
VG_(is_procfs_mounted)(). The old name was derived from the name
of the preprocessor macro HAVE_PROC while the new name is a more
accurate description of what this function does.

6b9dcdcd97 The configure-time test whether the proc filesystem is mounted (introduced
in r10156) broke cross-compilation. This patch converts the configure-time
test into a runtime test. Should fix bug #204843.

9acc4cc4d8 Fix the access_extended wrapper, which was rather broken. That's what I get
for not testing properly.  Added a regtest for it too.  Fixes bug 200760
(again, properly this time).

c922a7201d Add a crappy wrapper for access_extended(), one of the more ridiculous
syscalls I've had the displeasure of encountering.  Due to its
ridiculousness, the wrapper misses a PRE_MEM_WRITE check and so can result
in false positives.  The POST_MEM_WRITE update is present, though, so it
shouldn't cause subsequent problems.  Fixes bug 200760.

9cecb57a28 Handle the memory written by aio_read() properly -- mark the memory buffer
as written once aio_return() is successfully called.

Also check the addressability of the buffer for both aio_read() and
aio_write().

Also check the file descriptor for aio_read() and aio_write().

And add a test for this.  There's one corner case of the test that doesn't
work as expected and is currently commented out.  But aio_*() certainly
works better than it used to.

All this is for bug 197227.

e7dde85a24 Merge coregrind/ changes from branches/MESSAGING_TIDYUP r10464.
This commit tidies up and rationalises what could be called the
"messaging" system -- that part of V to do with presenting output to
the user.  In particular it brings significant improvements to XML
output.

Changes are:

* XML and normal text output now have separate file descriptors,
  which solves longstanding problems for XML consumers caused by
  the XML output getting polluted by unexpected non-XML output.

* This also means that we no longer have to hardwire all manner
  of output settings (verbosity, etc) when XML is requested.

* The XML output format has been revised, cleaned up, and made
  more suitable for use by error detecting tools in general
  (various Memcheck-specific features have been removed).  XML
  output is enabled for Ptrcheck and Helgrind, and Memcheck is
  updated to the new format.

* One side effect is that the behaviour of VG_(message) has been
  made to be consistent with printf: it no longer automatically
  adds a newline at the end of the output.  This means multiple
  calls to it can be used to build up a single line message; or a
  single call can write a multi-line message.  The ==pid==
  preamble is automatically inserted at each newline.

* VG_(message)(Vg_UserMsg, ..args..) now has the abbreviated form
  VG_(UMSG)(..args..); ditto VG_(DMSG) for Vg_DebugMsg and
  VG_(EMSG) for Vg_DebugExtraMsg.  A couple of other useful
  printf derivatives have been added to pub_tool_libcprint.h,
  most particularly VG_(vcbprintf).

* There's a small change in the core-tool interface to do with
  error handling: VG_(needs_tool_errors) has a new method
  void (*before_pp_Error)(Error* err)  which, if non-NULL, is
  called just before  void (*pp_Error)(Error* err).  This is to
  give tools the chance to look at errors before any part of them
  is printed, so they can print any XML preamble they like.

* coregrind/m_errormgr.c has been overhauled and cleaned up, and
  is a bit simpler and more commented.  In particular pp_Error
  and VG_(maybe_record_error) are significantly changed.

The diff is huge, but mostly very boring.  Most of the changes
are of the form

-   VG_(message)(Vg_UserMsg, "this is a message %d", n);
+   VG_(message)(Vg_UserMsg, "this is a message %d\n", n);

Unfortunately as a result of this, it touches a large number
of source files.

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.

b05a2a18d7 This commit merges the BUILD_TWEAKS branch onto the trunk. It has the
following improvements:

- Arch/OS/platform-specific files are now included/excluded via the
  preprocessor, rather than via the build system.  This is more consistent
  (we use the pre-processor for small arch/OS/platform-specific chunks
  within files) and makes the build system much simpler, as the sources for
  all programs are the same on all platforms.

- Vast amounts of cut+paste Makefile.am code has been factored out.  If a
  new platform is implemented, you need to add 11 extra Makefile.am lines.
  Previously it was over 100 lines.

- Vex has been autotoolised.  Dependency checking now works in Vex (no more
  incomplete builds).  Parallel builds now also work.  --with-vex no longer
  works;  it's little use and a pain to support.  VEX/Makefile is still in
  the Vex repository and gets overwritten at configure-time;  it should
  probably be renamed Makefile-gcc to avoid possible problems, such as
  accidentally committing a generated Makefile.  There's a bunch of hacky
  copying to deal with the fact that autotools don't handle same-named files
  in different directories.  Julian plans to rename the files to avoid this
  problem.

- Various small Makefile.am things have been made more standard automake
  style, eg. the use of pkginclude/pkglib prefixes instead of rolling our
  own.

- The existing five top-level Makefile.am include files have been
  consolidated into three.

- Most Makefile.am files now are structured more clearly, with comment
  headers separating sections, declarations relating to the same things next
  to each other, better spacing and layout, etc.

- Removed the unused exp-ptrcheck/tests/x86 directory.

- Renamed some XML files.

- Factored out some duplicated dSYM handling code.

- Split auxprogs/ into auxprogs/ and mpi/, which allowed the resulting
  Makefile.am files to be much more standard.

- Cleaned up m_coredump by merging a bunch of files that had been
  overzealously separated.

The net result is 630 fewer lines of Makefile.am code, or 897 if you exclude
the added Makefile.vex.am, or 997 once the hacky file copying for Vex is
removed.  And the build system is much simpler.

aa21ae3de1 Darwin syscall wrapper cleanups:
- Put Darwin syscall DECL_TEMPLATEs in syscall order.
- Removed the "sys_" prefix from Darwin-specific wrappers, it's not
  necessary.  Renamed a couple of other wrappers similarly.
- Removed the sys_fcntl64 Darwin wrapper, it was unused.
- Improved some code layout.
Overall this removes 6 "DDD"/"GrP" fixme comments.

2a7d944c27 A number of changes relating to syscall numbering:
- Introduced VG_SYSNUM_STRING and VG_SYSNUM_STRING_EXTRA which factor out
  differences in the way syscall numbers are printed on different platforms.
  This gets rid of seven "DDD" fixme-style comments.

- This also meant that Darwin syscall numbers are now printed in a
  non-ambiguous way -- previously Unix, machine-dependent and diagnostic
  syscalls were all printed the same way, even though their numbers overlap.
  Now each number is prefixed with "unix", "mdep", etc.  And Mach trap
  numbers aren't printed as negative numbers now that they have a "mach"
  prefix.

- Split each of pub_core_vkiscnums.h and pub_tool_vkiscnums.h into two
  parts, one suitable for inclusion in asm files, one suitable for inclusion
  in C files;  in both cases the latter includes the former.  This makes
  this module more like other modules that have asm-only components (eg.
  m_transtab);  it also allows the hacky VG_IN_ASSEMBLY_SOURCE macros and
  tests to be removed.

- Removed some of the VG_DARWIN_SYSNO_* macros that were no longer needed,
  and renamed some of the existing ones to make their meanings clearer.

- Added comments on the encoding of Darwin syscall numbers so it's
  possible for mortals to understand without reading the kernel 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.
