// We were trying to generate compact unwind info for assembly like this.
// The .cfi_def_cfa directive, however, throws a wrench into that and was
// causing an llvm_unreachable() failure. Make sure the assembler can handle
// the input. The actual eh_frames created using these directives are checked
// elsewhere. This test is a simpler "does the code assemble" check.
