Subject: Compiler option for SSE4
Date: Wed, 24 Mar 2010 06:09:00 -0000 [thread overview]
Message-ID: <417877.93242.qm@web65302.mail.ac2.yahoo.com> (raw)
Hi all,
I'm using GCC 4.1.2 20070626 on a server with Intel Xeon X5570.
How do I turn on the compiler option for SSE4? I've tried -msse4, -msse4.1 and -msse4.2, but they all returned the error message cc1: error: unrecognized command line option "-msse4.1" (for whichever option I tried).
Thank you.
Regards,
Weidong
