gem5/configs/test/test.py
Korey Sewell 19083bc4ce Added hook to check for SMT workloads. SMT is identified by adding a semicolon between
the workloads.

Now SMT on the O3CPU can be invoked by "/ALPHA_SE/m5.debug ../configs/test/test.py -d --cmd="hello;hello" -i="file1;file2"

I think I am a novice python magician now!!!!....

    (btw, We are back to working for this double hello world case)
