[FileCheck] Make FILECHECK_OPTS useful for its test suite Without this patch, `FILECHECK_OPTS` isn't propagated to FileCheck's test suite so that `FILECHECK_OPTS` doesn't inadvertently affect test results by affecting the output of FileCheck calls under test. As a result, `FILECHECK_OPTS` is useless for debugging FileCheck's test suite. In `llvm/test/FileCheck/lit.local.cfg`, this patch provides a new subsitution, `%ProtectFileCheckOutput`, to address this problem for both `FILECHECK_OPTS` and the deprecated `FILECHECK_DUMP_INPUT_ON_FAILURE`. The rest of the patch uses `%ProtectFileCheckOutput` throughout the test suite Fixes PR40284. Reviewed By: probinson, thopre Differential Revision: https://reviews.llvm.org/D65121

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

Improve error message of FileCheck when stdin is empty Summary: Replace '-' in the error message with <stdin>. This is also consistent with another error message in the code.

Fixup test after r352704 since it changes how paths may be emitted. On Unix/Mac OS X, normpath() returns the path unchanged (FileCheck), but on case-insensitive filesystems (like NTFS on Windows), it converts the path to lowercase (filecheck) which was causing the test to fail. llvm-svn: 352735

[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
