Oops. I have been forgeting to make sure to cc the list. And using the wrong from address as well... So I'm going to dump some of the older messages; they may be a repeat for some of you.

"The patch implements target hook TARGET_CANNOT_MODIFY_JUMPS_P in order to inhibit post-reload bb reorder for naked functions." http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42240 It looks like the patch to prevent reordering of instructions past the epilogue of naked functions prevents such reordering for the entire naked function. Though I'm not sure I understand why the original complaint was considered a bug. They appear to have been counting on a naked C function to fall in at the top and fall out at the bottom, which seems like even more of an abuse of "naked" than I was using (though I guess allowing that behavior is useful, especially in init code.)
