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.

The last SPEC 2006 can work on gcc-3.3.5 but you can use it with latest gcc like 4.4.5.

I'm new but I love to know How can I do it? If you can give me some suggestion I will appreciate it. > > >> ---------- Forwarded message ---------- >> From: Andrew Haley <aph@xxxxxxxxxx> >> To: gcc-help@xxxxxxxxxxx >> Date: Mon, 05 Sep 2011 09:31:29 +0100 >> Subject: Re: Want GCC 4.1.2 to run like SPEC 2006 GCC >> On 09/03/2011 01:02 PM, Milind wrote: >>> I want to run GCC 4.1.2 in a mode similar to GCC 3.2 present in SPEC >>> 2006 benchmarks: http://www.spec.org/auto/cpu2006/Docs/403.gcc.html >>> I do not need 100% parity, but at least fairly similar.
