Hi Andrew, I dont't know how to reply to a message on "gcc-help" mailing list so, I am directly writing to you. WRT your question: I am trying to see if some of the performance related observations I am doing on GCC coming with SPEC-2006 is not invalidated by more recent GCC versions. So, want to run same workloads on newer GCC to check that the findings are still relevant. Could you help me on teh flags that will make current GCC behave like the one in SPEC-2006? ---------- 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.
