This option is available for gcc 3.4 and upward, which reduces the .text binary size considerably. This option is the default for -O2 and above in gcc4 anyway. It might explain why I end up with a buggy Xen when I build with gcc4 (Linux has had a number of problems with -funit-at-a-time, because odf extra stack usage and code reordering). -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
