Update VerifyDiagnosticConsumer to only get directives during parsing. The old behavior was to re-scan any files (like modules) where we may have directives but won't actually be parsing during the -verify invocation. Now, we keep the old behavior in Debug builds as a sanity check (though modules are a known entity), and expect all legitimate directives to come from comments seen by the preprocessor. This also affects the ARC migration tool, which captures diagnostics in order to filter some out. This change adds an explicit cleanup to CaptureDiagnosticsConsumer in order to let its sub-consumer handle the real end of diagnostics. This was originally split into four patches, but the tests do not run cleanly without all four, so I've combined them into one commit. Patches by Andy Gibbs, with slight modifications from me. llvm-svn: 161650 2012-08-10 09:06:16 +08:00			`#if 0`

Provide -verify support to match "any" line for diagnostics in included files. Allow diagnostic checks that originate in included files to be matched without necessarily determining the line number that the diagnostic occurs on. The new syntax replaces the line number with '*'. This extension is limited to diagnostics in included files and may be used where the include file is not part of the test-suite itself. Expected uses are for diagnostics originating in system headers, or for users who use -verify in testing 3rd-party library code where the location of diagnostics in header files may change from revision to revision and their precise location is not important to the success of the test-case. llvm-svn: 212735 2014-07-11 00:43:29 +08:00
