GCC has option for Xeon cpu ???
Does anyone know that the latest GCC version 3.4 has "-mcpu "option for xeon cpu???
Each time when I compile code using gcc or g77, it will read information from file "specs" . I read file "specs" and see there are a couple of cpu options in the files, such as i386,. i486 , pentium, pentiumpro etc, but there is no xeon. I use GCC 3.1 so far . so when I specify the "-mcpu=xeon" in the command line, it said xeon is bad value.
If GCC 3.4 has xeon cpu option in the file "specs" , then maybe I can specify "-mcpu=xeon" in the compile command line to test my slower code on xeon machine. Check my previous thread if you have interest on my codes running slower on xeon machine who has higher speed and more memory.
By the way, what is the use of file "specs" ? I don't understand this file completely.
Any idea ???? Thanks to all of you in advance.
