Hi All,
Recently I am using Marss to simulate a machine with 2 cores. I run Marss for
many times, but frequently receive assertion message as below:
"int ooo::ReorderBufferEntry::commit(): Assertion 'ctx.get_cs_eip() == uop.rip'
failed."
Debug message:
---------------------------------------------------------------------------------------
RIP dont match at commit time:
SMT per-thread state for t0:
