Hi Ramana and Nick,
Thank you for your help.

I would also like to know how to run a single file from gas test suite?
I am able to run gas test suite in a one shot and got 72 PASSES without
any error or failure. But when I am trying to run a single file (e.g.
gas/cfi/cfi.exp) as:

$runtest gas/cfi/cfi.exp 

then I got an error generated in dejagnu (runtest.exp file). 
----------------------------------
send: spawn id exp0 not open
    while executing
"send_user "$message\n""
    ("default" arm line 2)
    invoked from within
"case "$firstword" in {
        {"PASS:" "XFAIL:" "KFAIL:" "UNRESOLVED:" "UNSUPPORTED:"
"UNTESTED:"} {
            if $all_flag {
                send_user "$message\n"
                return "..."
    (procedure "clone_output" line 10)
    invoked from within
"clone_output "\n\t\t=== $tool Summary ===\n""
    (procedure "log_summary" line 23)
    invoked from within
"log_summary total"
    (procedure "log_and_exit" line 5)
    invoked from within
"log_and_exit"
    (file "/usr/local/share/dejagnu/runtest.exp" line 1912)
-------------------------------

Does gas test suite support for execution of single .exp file??

thanks
Jitendra
