The problem with this patch is that for some of the things you fixed, stuff like boot-time programs, you NEVER want any CPU specific settings! You must use the default, lowest common denominator setting instead, or there is no guarantee the boot program will be correct. So that is why these Makefiles purposefully overwrite CFLAGS, it is not by accident. Besides, for space-constrained things like boot2, you might not even be able to compile it when using non-standard settings, since the code might grow too large.Received on Tue May 24 2011 - 18:41:02 UTC
