Look at the -march and -mtune gcc flags
How to compile c code taking advantage of CPU specific features
문제
If on linux I try to compile c code in the standard way
gcc -myprog.c
the generated binary uses only the base CPU features, since the modern CPUs have a lot of special features to increase the performances, like AVX, AVX2, SSE3, SSE4 etc. according the model
Since I want targeting only a specific CPU type (i7 Sandy Bridge), Is there a way to set the copiler to take advantage of these features?
