Author: mcrosier Date: Wed May 1 14:50:45 2013 New Revision: 180874 URL: http://llvm.org/viewvc/llvm-project?rev=180874&view=rev Log: [inline asm] Add a test case for r180873. Test case needs to be on the clang side because we need an inline asm diagnostics handler in place. Unfortunately, we emit a .s file because we need to build the SelectionDAG to hit the backend issue. rdar://13446483
