So, AFAIU, PR56242 might still trigger for picochip. No. It is impossible for a target to have SEQUENCEs and a CFG at the same time. The CFG code doesn't handle SEQUENCEs. Having SEQUENCEs for delay slots in the CFG would result in a verify_flow_info failure, because there would be non-jump insns (i.e. the SEQUENCE) at the end of basic blocks ending in a branch. Any target pretends to have a valid CFG and SEQUENCEs at the same time is broken.
