PR rtl-optimization/48302
* sel-sched-ir.h (sel_add_loop_preheaders): Update prototype.
* sel-sched-ir.c (sel_add_loop_preheaders): Add 'bbs' argument. Use
it to record added preheader blocks.
* sel-sched.c (setup_current_loop_nest): Add 'bbs' argument. Pass it
on to sel_add_loop_preheaders.
(sel_region_init): Move call to setup_current_loop_nest after
sel_init_bbs.
testsuite:
* g++.dg/opt/pr48302.C: New.
