Djordje Todorovic 88aa158bd7 Recommit: "[Debugify][Original DI] Test dbg var loc preservation"" ... [Debugify][Original DI] Test dbg var loc preservation This is an improvement of [0]. This adds checking of original llvm.dbg.values()/declares() instructions in optimizations. We have picked a real issue that has been found with this (actually, picked one variable location missing from [1] and resolved the issue), and the result is the fix for that -- D100844. Before applying the D100844, using the options from [0] (but with this patch applied) on the compilation of GDB 7.11, the final HTML report for the debug-info issues can be found at [1] (please scroll down, and look for "Summary of Variable Location Bugs"). After applying the D100844, the numbers has improved a bit -- please take a look into [2].
