I test most of the branch of SPEC 2006 in GCC 4.5.2 without any
problem. If you find a problem you can send it to me, If I can resolve
I will happy and I will send it to you.

Do you want run SPEC 2006 on Simplescalar?

The last SPEC 2006 can work on gcc-3.3.5 but you can use it with
latest gcc like 4.4.5.
And another suggestion is install gcc version 3.3.5(but I don't recommended)

Dead Andrew
I think it's so difficult at this time as a senior student, say what I
need. I'm new but I love to know How can I do it?
If you can give me some suggestion I will appreciate it.
