re PR target/48273 (ICE: in create_copy_of_insn_rtx, at sel-sched-ir.c:5604 with -fsel-sched-pipelining -fselective-scheduling2 -march=core2)
PR target/48273
* cfgloop.h (loop_has_exit_edges): New helper.
* sel-sched-ir.c (init_global_and_expr_for_insn): Make CALLs
non-clonable.
* sel-sched.c (sel_setup_region_sched_flags): Don't pipeline loops
that have no exit edges.
testsuite:
* g++.dg/opt/pr48273.C: New.
