William,

> What is the best way to check whether the "sim" is running standalone or by GDB ?

In sim_open, the first parameter is "SIM_OPEN_KIND kind".  When sim_open is called in \
standalone (i.e., from nrun.c), this parameter is SIM_OPEN_STANDALONE) and when \
called from GDB, it is SIM_OPEN_DEBUG.  This can be saved and checked later.

A typical call in sim_open is:

SIM_DESC sd = sim_state_alloc(kind, callback);

which saves kind in the sd structure.  You can use STATE_OPEN_KIND(sd) to examine it \
in any function that receives an "sd".

Hope this helps.

   Michael
