Is this
Hi,
In tree-vect-loop.c, it limits the vectorization only to loops that have 2 BBs:
/* Inner-most loop. We currently require that the number of BBs is
exactly 2 (the header and latch). Vectorizable inner-most loops
look like this:
(pre-header)
It would probably be a good idea to mention:
contrib/download_prerequisites
on this page:
http://gcc.gnu.org/install/prerequisites.html
and probably on this page:
http://gcc.gnu.org/install/download.html
Sincerely,

I think what you're saying is that the p_eh_frame_hdr field could
end up with a dangling poin
