mips-elf has had regressions ever since the INSN_SCOPE changes were installed
into the tree. While the number of regressions has gone down since the
introduction of the INSN_SCOPE changes one regression still remains.
The remaining regression is gcc.dg/debug/debug-6 where we manage to lose
all debug information for "xyzzy". I believe the fundamental problem is your
code in scope_to_insns_initialize does not properly handle SEQUENCEs as
generated by the delay slot filling pass.
For the record, this is failing on the sparc targets too. I bet it is
failing elsewhere...
