It is not only choice between removed debug info (removing some debug insns in bery rare cases) or wrong debug info (assigning memory to pseudo living only in debug insns). The two different solutions I have now unfortunately affect fundamental assumption that code with debug and without debug info should be the same: I have 2 new GCC test regressions when -fcompare-debug is used. So fixing it will take more time than I evaluated before.
