Subject: [RFC] is-a.h supporting casting from non const to const
Authentication-results: sourceware.org; auth=none

Hi,
  While working on a patch to change some error to inform, I changed
the as_a cast in RTL_LOCATION to be as_a <const rtx_insn *>.  This
falls down when you start with a rtx rather than a const_rtx..

I had to modify is-a.h to this but I really don't like the
modification at all since it shows the bigger issues with templates.
Can anyone think of a better way of supporting this?  Attached is my
patch currently which is able to bootstrap with the modification to
RTL_LOCATION being there.

Thanks,
Andrew Pinski
