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_STAND=
ALONE) and when called from GDB, it is SIM_OPEN_DEBUG.  This can be saved a=
nd checked later.

A typical call in sim_open is:

SIM_DESC sd =3D sim_state_alloc(kind, callback);

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

Hope this helps.
