Compiling with -g slows down compilation and link, mainly because of the extra debugging data that has to be copied around. -g significantly increases disk usage. >If that's true, then why dont we compile kernels with both -g and -O2 >always?

One of my occasional tests is to build vmlinux with and without -g, run both through strip -g and compare the results. They should be identical except for the build timestamp. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
