Hi, I know the target triplet is the cpu-vendor-os triplet where the executable runs. Does changing the cpu from i386-pc-mingw32 to i686-pc-mingw32 actually change executable that is created? Does gcc get special options to tell it to optimize for a particular CPU? If not, does anyone know where the correct place to ask about cpu specific gcc optimizations would be?
