Sounds great to me. PowerPC already arranges for _start to be at the very beginning of .text, which is at the beginning of the first PT_LOAD segment... so the end result is that the address of _start is the same as our link address. We also provide _etext, and _end, but not _stext (currently). -- Hollis Blanchard IBM Linux Technology Center _______________________________________________ Xen-ppc-devel mailing list Xen-ppc-devel@lists.xensource.com http://lists.xensource.com/xen-ppc-devel
