[Gold] Can't we specify input files & libraries in linker scripts ?

[Shawn]

Hi Lan:
     Sorry to bother you again.
     We have ported the Gold to our DSP architecture and we have 
encountered some difficulties and really need your help.

It's ok to specify the input files & libraries in the command line,But  
if we add default libraries to be linked in linker script with the 
"GROUP" clause, "internal error" occurs.  This "internal error" occurs 
because of the  assertion in binutlis-2.23.2/gold/script.cc:1600 ,which 
says :

gold_assert(!closure.saw_inputs());

Does it means we can't specify any input files & libraries in linker 
script ?

thanks in advance.

Shawn.
