PR gnu/26083 includes patches gcc to support the same -malign-XXX=N functionality as the i386. My kernel text segment shrank about 10% when I built it with 32-bit alignment (ISO 16-byte jump and 32-byte function alignment). The padding should compress fairly well, and I haven't tried building boot floppies with it so I don't know what the overall savings would be. > Currently our alpha install >floppies are ufs filesystems and it occurred to me that cd9660 might be a >bit more space efficient. Why not go the whole hog and build something that just uses a name, start block and length. This would reduce the FS overhead to 1 block. (I think the UFS overhead is ~24k, I'm not sure about cd9660). Peter To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
