Hello, I'm getting an assertion in register allocator, specifically in LiveIntervalAnalysis.h, method LiveIntervals::getInstructionIndex: unsigned getInstructionIndex(MachineInstr* instr) const { Mi2IndexMap::const_iterator it = mi2iMap_.find(instr); assert(it != mi2iMap_.end() && "Invalid instruction!"); return it->second; } The crash happens when the function is called from LiveIntervalAnalysis.cpp, 360: for (unsigned i = 0, e = vi.Kills.size(); i != e; ++i)...

I've checked...

Hi Evan, Here is a patch for the LiveIntervalAnalysis that we discussed. --- Evan Cheng <evan.cheng at apple.com> schrieb: > > 1) What is the easiest way to understand which MBB a given > instruction index belongs to?
