/* Constants which are used as the lowest 2 bits in origin tags.
   
   An origin tag comprises an upper 30-bit ECU field and a lower 2-bit
   'kind' field.  The ECU field is a number given out by m_execontext
   and has a 1-1 mapping with ExeContext*s.  An ECU can be used
   directly as an origin tag (otag), but in fact we want to put
   additional information 'kind' field to indicate roughly where the
   tag came from.  This helps print more understandable error messages
   for the user -- it has no other purpose.

   Hence the following 2-bit constants are needed for 'kind' field. 

   To summarise:

   * Both ECUs and origin tags are represented as 32-bit words

   * m_execontext and the core-tool interface deal purely in ECUs.
     They have no knowledge of origin tags - that is a purely
     Memcheck-internal matter.

   * all valid ECUs have the lowest 2 bits zero and at least
     one of the upper 30 bits nonzero (see VG_(is_plausible_ECU))

   * to convert from an ECU to an otag, OR in one of the MC_OKIND_
     constants below

   * to convert an otag back to an ECU, AND it with ~3

/* Indicates the level of instrumentation/checking done by Memcheck.

   1 = No undefined value checking, Addrcheck-style behaviour only:
       only address checking is done.  This is faster but finds fewer
       errors.  Note that although Addrcheck had 1 bit per byte
       overhead vs the old Memcheck's 9 bits per byte, with this mode
       and compressed V bits, no memory is saved with this mode --
       it's still 2 bits per byte overhead.  This is a little wasteful
       -- it could be done with 1 bit per byte -- but lets us reuse
       the many shadow memory access functions.  Note that in this
       mode neither the secondary V bit table nor the origin-tag cache
       are used.

   2 = Address checking and Undefined value checking are performed,
       but origins are not tracked.  So the origin-tag cache is not
       used in this mode.  This setting is the default and corresponds
       to the "normal" Memcheck behaviour that has shipped for years.

   3 = Address checking, undefined value checking, and origins for
       undefined values are tracked.

   The default is 2.
