- Subject: MMX instruction and gcc
Hi,
I want ask, if there is posibilities that gcc will be automaticaly
generates MMX instruction? I tried -mtune, -march -mmmx. But gcc stil
generates code without MMX instruction. On net I found only
information about inline assembler function or citation from man page.
I tried to compile program for adding two arrays of 24 chars.
Thank for help
