The test in PR24199 ( https://llvm.org/bugs/show_bug.cgi?id=24199 ) crashes because machine trace metrics was not ignoring dbg_value instructions when calculating data dependencies. The machine-combiner pass asks machine trace metrics to calculate an instruction trace, does some reassociations, and calls MachineInstr::eraseFromParentAndMarkDBGValuesForRemoval() along with MachineTraceMetrics::invalidate(). The dbg_value instructions have their operands invalidated, but the instructions are not expected to be deleted. On a subsequent loop iteration of the machine-combiner pass, machine trace metrics would be called again and die while accessing the invalid debug instructions.
