Mark, do you have an opinion on the following implementation detail? We don't
want to duplicate the code of may_trap_p and rtx_addr_can_trap_p, so the new
predicate will essentially piggyback on it, simply bypassing MEM_NOTRAP_P and
adding the supplementary check on the alignment on STRICT_ALIGNMENT machines.
Now this new predicate will only be invoked (for now) from reorg.c and only do
something new on STRICT_ALIGNMENT machines, so I'm not really thrilled to
propagate an additional argument all the way through the recursion in
may_trap_p; that's why I was pondering adding a global flag instead, possibly
forced to "const bool false" if not on a STRICT_ALIGNMENT machine. Thanks in
advance.
