ModuleID This is done to avoid odd test failures, like the one fixed in r171243. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171246 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-29Add testcase for r132290, to check for the crasher caught by the buildbotsNick Lewycky
doing llvm-gcc selfhost (or cross). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132292 91177308-0d34-0410-b5e6-96231b3b80d8
