re PR tree-optimization/89572 (ICE in dyn_cast<gcond*, gimple>(gimple*) / get_loop_exit_condition(loop const*))
2019-03-14 Richard Biener <rguenther@suse.de>
PR middle-end/89572
* tree-scalar-evolution.c (get_loop_exit_condition): Use
safe_dyn_cast.
* tree-ssa-loop-ivcanon.c (canonicalize_loop_induction_variables):
Use gimple_location_safe.
* gcc.dg/torture/pr89572.c: New testcase.
