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

; NO-EMPTY-ERR-NOT: FileCheck error: '-' is empty.
[FileCheck] Implement -v and -vv for tracing matches -v prints all directive pattern matches. -vv additionally prints info that might be noise to users but that can be helpful to FileCheck developers. To maximize code reuse and to make diagnostics more consistent, this patch also adjusts and extends some of the existing diagnostics. CHECK-NOT failures now report variables uses. Many more diagnostics now report the check prefix and kind of directive. Reviewed By: probinson Differential Revision: https://reviews.llvm.org/D47114 llvm-svn: 336967
