at ../lib/CodeGen/LiveIntervals.cpp:493
493 assert(r2iA != r2iMap_.end());
The instruction it crashes is:
(gdb) p $4.dump()
%reg1056 = move %gr7
And gr7 is exactly the register which is looked up with
Reg2IntervalMap::iterator r2iA = r2iMap_.find(regA)
on line 492. I'm not sure the about the logic, but seems the code tries to map
register into live interval, and since the above gr7 is inserted by code
selector (it's return value from a function), it's not wonder no interval is
