FileCheck: Add a flag to allow checking empty input Currently FileCheck errors out on empty input. This is usually the right thing to do, but makes testing things like "this command does not emit some error message" hard to test. This usually leads to people using "command 2>&1 | count 0" instead, and then the bots that use guard malloc fail a few hours later. By adding a flag to FileCheck that allows empty inputs, we can make tests that consist entirely of "CHECK-NOT" lines feasible. llvm-svn: 215127
