Which compiler flags are optimal for the Intel C Compiler on AMD FX 8350?
I would like to use the Intel C Compiler due to its superior vectorization abilities. However, it understandably has no -march=bdver2 flag which is what I would use on gcc for my AMD FX-8350 CPU. It does have -xavx but I am not sure what other flags to use.
What are the optimal compiler flags for the AMD FX-8350 CPU using the Intel C Compiler?
cat /proc/cpuinfo |grep flags gives:
