Intel compiler question
Author:  Date: 2010-10-11 06:21
Hello Agner and thank you for sharing all of your wisdom with us, it's really appreciated.

At the time of writing there's the following paragraph in your optimizing software in C++ manual:

"Programs compiled with the Intel compiler with the /Qax option will run sub-optimally on non-Intel processors unless the above patch is included. Programs compiled with the /Qx option will not run at all on non-Intel processors unless the above patch is included."

Does that mean that the unfair CPU path dispatcher is only present when either of those switches are used in the compilation? Or is it present too when using /arch:SSE3 only for example?

Thank you very much for your time, kind regards,
J. Russell.
