My first thought WRT the actual patch itself is why not put the logic to fixup
the insn chain for SEQUENCEs at the end of reorder_insns_nobb? That would
avoid similar problems for any other code that used this function after reorg.c
had started.
It also seems to me there are 4 cases that need to be fixed.
FROM is a SEQUENCE
Need to fix PREV_INSN of the first insn in the SEQUENCE
TO is a SEQUENCE
Need to fix NEXT_INSN of the last insn in the SEQUENCE
PREV_INSN (FROM) is a sequence
Need to fix NEXT_INSN of the last INSN in the SEQUENCE
NEXT_INSN (TO) is a sequence
Need to fix PREV_INSN of the first INSN in the SEQUENCE
Am I missing something here?
