--- Comment #25 from Terry Guo <xuepeng.guo at intel dot com> --- Debugged the ICE further and found that below line in function ix86_get_drap_rtx is causing ICE: 12050 insn = emit_insn_before (seq, NEXT_INSN (entry_of_function ())); It is called when generating call to __asan_stack_free_5 via emit_library_call_value_1. The entry_of_function() is returned something invalid.
