/* Magic values that the guest state 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. These also are return values from
from VG_(run_innerloop) to the scheduler.
/* Defines values for JMP_EMWARN, JMP_SYSCALL, JMP_CLIENTREQ and
#include "libvex_trc_values.h"
/* And some more of our own. These must not have the same values as
those from libvex_trc_values.h. (viz, 60 or below is safe).
(The following comment is no longer relevant, but is retained
for historical purposes.)
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.
