[gentoo-ppc-user] -mabi=altivec in CFLAGS
Hi all, AFAIK, some packages (e.g., dev-cpp/eigen) can use AltiVec vectorization only when -mabi=altivec is specified in GCC flags. Is it safe to use -mabi=altivec in global CFLAGS in make.conf? Does anybody know if the system will perform better or worse in average? -- Regards, Konstantin
