re PR rtl-optimization/46875 (ICE: verify_flow_info failed: too many outgoing branch edges from bb 3 with -Os -fselective-scheduling2)
PR rtl-optimization/46875
* sched-vis.c (print_pattern): Dump "sequence" for ADDR_VECs.
* sel-sched-ir.c (bb_has_removable_jump_to_p): Forbid table jumps.
testsuite:
* gcc.dg/pr46875.c: New.
