re PR rtl-optimization/46614 (gcc.dg/vect/vect-strided-u8-i8-gap4.c FAILs with -fno-rename-registers -fsched2-use-superblocks)
PR rtl-optimization/46614
* sched-deps.c (NON_FLUSH_JUMP_KIND, NON_FLUSH_JUMP_P): Define.
(deps_analyze_insn): Mark JUMP_INSNs in
last_pending_memory_flush that weren't added through
flush_pending_lists with NON_FLUSH_JUMP_KIND.
(sched_analyze_2, sched_analyze_insn): Check NON_FLUSH_JUMP_P
on INSN_LIST instead of JUMP_P check on its operand.
* sched-rgn.c (concat_INSN_LIST): Copy over REG_NOTE_KIND.
* gcc.dg/pr46614.c: New test.
