test that the ptr-to-method is succefully eliminated, leaving just the vtable dispatch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41047 91177308-0d34-0410-b5e6-96231b3b80d8 2007-08-13 17:17:03 +00:00			`// PR1602`
Remove explicit uses of -emit-llvm, the test infrastructure adds it automatically. Use -S with llvm-gcc rather than -c, so tests can work when llvm-gcc is really dragonegg (which can output IR with -S but not -c). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120160 91177308-0d34-0410-b5e6-96231b3b80d8 2010-11-25 21:39:17 +00:00			`// RUN: %llvmgxx -S %s -o - -O3 \| not grep ptrtoint`
Due to changes coming from the new LLVM type system, you now get bitcasts in this test rather than getelementptr instructions; llvm-gcc produces two bitcasts, clang produces one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136349 91177308-0d34-0410-b5e6-96231b3b80d8 2011-07-28 12:21:47 +00:00			`// RUN: %llvmgxx -S %s -o - -O3 \| not grep getelementptr`
