Vedant Kumar 105b2b3c98 [Debugify] Add a pass to test debug info preservation ... The Debugify pass synthesizes debug info for IR. It's paired with a CheckDebugify pass which determines how much of the original debug info is preserved. These passes make it easier to create targeted tests for debug info preservation. Here is the Debugify algorithm: NextLine = 1 for (Instruction &I : M) attach DebugLoc(NextLine++) to I NextVar = 1 for (Instruction &I : M) if (canAttachDebugValue(I)) attach dbg.value(NextVar++) to I The CheckDebugify pass expects contiguous ranges of DILocations and DILocalVariables. If it fails to find all of the expected debug info, it prints a specific error to stderr which can be FileChecked. This was discussed on llvm-dev in the thread: "Passes to add/validate synthetic debug info" Differential Revision: https://reviews.llvm.org/D40512 llvm-svn: 320202		2017-12-08 21:57:28 +00:00
