+/***************************************************************************/
+/* To use the cycle counters in your code, simply #include "cycle.h" (this
+   file), and then use the functions/macros:
+
+                 CycleCounterTicks getticks(void);
+
+   CycleCounterTicks is an opaque typedef defined below, representing the current time.
+   You extract the elapsed time between two calls to gettick() via:
+
+                 double elapsed(CycleCounterTicks t1, CycleCounterTicks t0);
+
+   which returns a double-precision variable in arbitrary units.  You
+   are not expected to convert this into human units like seconds; it
+   is intended only for *comparisons* of time intervals.
+
+   (In order to use some of the OS-dependent timer routines like
+   Solaris' gethrtime, you need to paste the autoconf snippet below
+   into your configure.ac file and #include "config.h" before cycle.h,
+   or define the relevant macros manually if you are not using autoconf.)

+/* The following defines the magic code sequences which the JITter

+   they will rot your brain.
+
+   The assembly code sequences for all architectures is in this one
+   file.  This is because this file must be stand-alone, and we don't
+   want to have multiple files.
+
+   For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default
+   value gets put in the return slot, so that everything works when
+   this is executed not under Valgrind.  Args are passed in a memory
+   block, and so there's no intrinsic limit to the number that could
+   be passed, but it's currently five.
+   
+   The macro args are: 
+      _zzq_rlval    result lvalue
+      _zzq_default  default value (result returned when running on real CPU)
+      _zzq_request  request code
+      _zzq_arg1..5  request params
+
+   The other two macros are used to support function wrapping, and are
+   a lot simpler.  VALGRIND_GET_NR_CONTEXT returns the value of the
+   guest's NRADDR pseudo-register and whatever other information is
+   needed to safely run the call original from the wrapper: on
+   ppc64-linux, the R2 value at the divert point is also needed.  This
+   information is abstracted into a user-visible type, OrigFn.
+
+   VALGRIND_CALL_NOREDIR_* behaves the same as the following on the
+   guest, but guarantees that the branch instruction will not be
+   redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64:
+   branch-and-link-to-r11.  VALGRIND_CALL_NOREDIR is just text, not a
+   complete inline asm, since it needs to be combined with more magic
+   inline asm stuff to be useful.

+/* NB 9 Sept 07.  There is a nasty kludge here in all these CALL_FN_
+   macros.  In order not to trash the stack redzone, we need to drop
+   %rsp by 128 before the hidden call, and restore afterwards.  The
+   nastyness is that it is only by luck that the stack still appears
+   to be unwindable during the hidden call - since then the behaviour
+   of any routine using this macro does not match what the CFI data
+   says.  Sigh.
+
+   Why is this important?  Imagine that a wrapper has a stack
+   allocated local, and passes to the hidden call, a pointer to it.
+   Because gcc does not know about the hidden call, it may allocate
+   that local in the redzone.  Unfortunately the hidden call may then
+   trash it before it comes to use it.  So we must step clear of the
+   redzone, for the duration of the hidden call, to make it safe.
+
+   Probably the same problem afflicts the other redzone-style ABIs too
+   (ppc64-linux, ppc32-aix5, ppc64-aix5); but for those, the stack is
+   self describing (none of this CFI nonsense) so at least messing
+   with the stack pointer doesn't give a danger of non-unwindable
+   stack. */

+/* Mark a block of memory as having been allocated by a malloc()-like

+   redzone) `rzB' is redzone size if the allocator can apply redzones;
+   use '0' if not.  Adding redzones makes it more likely Valgrind will spot
+   block overruns.  `is_zeroed' indicates if the memory is zeroed, as it is
+   for calloc().  Put it immediately after the point where a block is
+   allocated. 
+   
+   If you're using Memcheck: If you're allocating memory via superblocks,
+   and then handing out small chunks of each superblock, if you don't have
+   redzones on your small blocks, it's worth marking the superblock with
+   VALGRIND_MAKE_MEM_NOACCESS when it's created, so that block overruns are
+   detected.  But if you can put redzones on, it's probably better to not do
+   this, so that messages for small overruns are described in terms of the
+   small block rather than the superblock (but if you have a big overrun
+   that skips over a redzone, you could miss an error this way).  See
+   memcheck/tests/custom_alloc.c for an example.
+
+   WARNING: if your allocator uses malloc() or 'new' to allocate
+   superblocks, rather than mmap() or brk(), this will not work properly --
+   you'll likely get assertion failures during leak detection.  This is
+   because Valgrind doesn't like seeing overlapping heap blocks.  Sorry.
+
+   Nb: block must be freed via a free()-like function specified
+   with VALGRIND_FREELIKE_BLOCK or mismatch errors will occur. */
