41    returning to the dispatcher.  The only other legitimate value is to
42    point to the start of the thread's VEX guest state.
43 
44    This file may get included in assembly code, so do not put
45    C-specific constructs in it.
46 
47    These values should be 61 or above so as not to conflict
48    with Valgrind's VG_TRC_ values, which are 60 or below.
49 
50    These values *must* be odd (have bit 0 set) because the dispatchers
51    (coregrind/m_dispatch/dispatch-*-*.S) use this fact to distinguish
52    a TRC value from the unchanged baseblock pointer -- which has 0 as
53    its lowest bit.
