/* ---------------------------------------------------------------------
   ALL THE CODE IN THIS FILE RUNS ON THE SIMULATED CPU. 

   These functions are not called directly - they're the targets of code
   redirection or load notifications (see pub_core_redir.h for info).
   They're named weirdly so that the intercept code can find them when the
   shared object is initially loaded.

   Note that this filename has the "vg_" prefix because it can appear
   in stack traces, and the "vg_" makes it a little clearer that it
   originates from Valgrind.
