re PR rtl-optimization/45353 (ICE: RTL check: expected elt 3 type 'B', have '0' (rtx barrier) in sel_bb_head, at sel-sched-ir.c:4329 with -fselective-scheduling and __builtin_unreachable())
PR rtl-optimization/45353
* sel-sched-ir.c (sel_bb_head): Return NULL even if next_nonnote_insn
after bb_note is a BARRIER.
* gcc.dg/pr45353.c: New test.
