The new binutils screws over some basic long-standing assumptions about field ordering and associativity in the object files, which are no longer maintained (for whatever reason) in the new version of the tools. Some of them have been identified and repaired (e.g. the Alpha code changes for the section/segment order assumption), but it is going to probably be a long battle. Technically, the ELF spec permits the ordering, so the assumptions are really "broken", even though they code for what's really a defacto-standard of many years, now. 8-(. I hate the new binutils, but they are required for support for the 64 bit architectures, so they are not going to just go away. I think retrofitting support for these architectures into the old binutils would be a mistake. It's a little sad, since with the assumptions, the code would have been faster on initial execution, than without them. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
