Hey Joel... I have one. :)

(gdb) tar sim

Breakpoint 1, sim_open (kind=SIM_OPEN_DEBUG, callback=0x828a6c0, abfd=0x0,
    argv=0x9c90b58) at ../../../gdb-6.6/sim/erc32/interf.c:191
191         sim_callback = callback;
(gdb) p argv
$1 = (char **) 0x9c90b58
(gdb) p *argv
$2 = 0x9c90a58 "gdbsim"
(gdb) p argv[1]
$3 = 0x9c90a68 "-E"
(gdb) p argv[2]
$4 = 0x9c90a78 "big"
(gdb) p argv[3]
$5 = 0x0
(gdb)           

Every simulator "sim_open" call now gets passed a "-E endian" option which
the sis simulator did not get updated to add enough to parse this 
option.  It doesn't
have to do anything but ignore it but it should parse it.

Patch attached.
