Author: asmith Date: Mon Mar 11 19:00:39 2019 New Revision: 355890 URL: http://llvm.org/viewvc/llvm-project?rev=355890&view=rev Log: [DebugInfo] Add test cases for FlagNonTrivial
Summary: This is a test case to go with D44406 which added FlagNonTrivial to mark that a C++ record is non-trivial to support CodeView debug emission. While it looks like FlagTypePassByValue can imply triviality and FlagTypePassByReference can imply non-triviality that is not true. Some non-trivial cases use a combination of FlagNonTrivial and FlagTypePassByValue instead of FlagTypePassByReference. See the test cases and D44406 for discussion.
