98908947c7 This commit is for Bugzilla 334834. The Bugzilla contains patch 2 of 3
to add PPC64 LE support.  The other two patches can be found in Bugzillas
334384 and 334836.

POWER PC, add the functional Little Endian support, patch 2 

The IBM POWER processor now supports both Big Endian and Little Endian.
The ABI for Little Endian also changes.  Specifically, the function
descriptor is not used, the stack size changed, accessing the TOC
changed.  Functions now have a local and a global entry point.  Register
r2 contains the TOC for local calls and register r12 contains the TOC
for global calls.  This patch makes the functional changes to the
Valgrind tool.  The patch makes the changes needed for the
none/tests/ppc32 and none/tests/ppc64 Makefile.am.  A number of the
ppc specific tests have Endian dependencies that are not fixed in
this patch.  They are fixed in the next patch.

Per Julian's comments renamed coregrind/m_dispatch/dispatch-ppc64-linux.S
to coregrind/m_dispatch/dispatch-ppc64be-linux.S  Created new file for LE
coregrind/m_dispatch/dispatch-ppc64le-linux.S.  The same was done for
coregrind/m_syswrap/syscall-ppc-linux.S.

to add PPC64 LE support.  The other two patches can be found in Bugzillas
334834 and 334836.  The commit does not have a VEX commit associated with it.

POWER PC, add initial Little Endian support

The IBM POWER processor now supports both Big Endian and Little Endian.
This patch renames the #defines with the name ppc64 to ppc64be for the BE
specific code.  This patch adds the Little Endian #define ppc64le to the

Additionally, a few functions are renamed to remove BE from the name if the
function is used by BE and LE. Functions that are BE specific have BE put
in the name.

The goals of this patch is to make sure #defines, function names and
variables consistently use PPC64/ppc64 if it refers to BE and LE,
PPC64BE/ppc64be if it is specific to BE, PPC64LE/ppc64le if it is LE
specific.  The patch does not break the code for PPC64 Big Endian.

The test files memcheck/tests/atomic_incs.c, tests/power_insn_available.c
and tests/power_insn_available.c are also updated to the new #define
definition for PPC64 BE.

fill up the guest state. This is MIPS-only change.

f3a7b3a8b9 arm-linux: make restarting interrupted syscalls work in Thumb mode.
This isn't exactly right, in the sense that the if the SVC instruction
was conditional, then it will be restarted with the condition for the
following instruction.  IOW we should back up ITSTATE too, but don't.
This doesn't happen in glibc, though, afaics.

Also tighten up the checks for restarting in ARM mode.

239f21d07e If a signal arrives when a thread which has just finished executing a
system call is between the blksys_committed and blksys_finished markers
in the system call routine then the post handler for the system call
was failing to run.

This commit fixes that by ensuring that the syscall status is recovered
from the guest state before the post VG_(post_syscall) is called just
as VG_(client_syscall) would normally do when the assembly wrapper
returned. Without that VG_(post_syscall) will not do anything a it
will think the system call is still running.

Fixes #212267.

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.

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.

ae8215b3ac Create a new module, m_vki, and move all knowledge about the kernel
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.
