/* Magic values that the guest state pointer might be set to when
   returning to the dispatcher.  The only other legitimate value is to
   point to the start of the thread's VEX guest state.

   This file may get included in assembly code, so do not put
   C-specific constructs in it.

   These values should be 61 or above so as not to conflict
   with Valgrind's VG_TRC_ values, which are 60 or below.

   These values *must* be odd (have bit 0 set) because the dispatchers
   (coregrind/m_dispatch/dispatch-*-*.S) use this fact to distinguish
   a TRC value from the unchanged baseblock pointer -- which has 0 as
   its lowest bit.
