// PURPOSE: This module contains the inner loop of the execution
// mechanism, which is: find next basic block, execute it, repeat until
// the next bb isn't found in the fast-cache; or if the current bb
// exited with a request for some special action before continuing; or
// if the current thread has used up its scheduling quantum.
//--------------------------------------------------------------------

/* This subroutine is called from the C world.  It is passed
   a pointer to the VEX guest state (arch.vex).  It must run code
   from the instruction pointer in the guest state, and exit when
   VG_(dispatch_ctr) reaches zero, or we need to defer to the scheduler.
   The return value must indicate why it returned back to the scheduler.
   It can also be exited if the executing code throws a non-resumable
   signal, for example SIGSEGV, in which case control longjmp()s back past
   here.

   This code simply handles the common case fast -- when the translation
   address is found in the translation cache.  For anything else, the
   scheduler does the work.
