llvm-mirror/test/FrontendC++/2007-05-16-ReverseBitFieldCrash.cpp
Duncan Sands 241d75b40f 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).
