static

CheckLists - Compare expected to seen diagnostic lists and return the the difference between them.

CheckResults()

static unsigned CheckResults ( DiagnosticsEngine &  Diags, SourceManager &  SourceMgr, const TextDiagnosticBuffer &  Buffer, ExpectedData &  ED  )

static

CheckResults - This compares the expected results to those that were actually reported.

It emits any discrepencies. Return "true" if there were problems. Return "false" otherwise.

findDirectives()

static bool findDirectives ( SourceManager &  SM, FileID  FID, const LangOptions &  LangOpts  )

static

Lex the specified source file to determine whether it contains any expected-* directives.

As a Lexer is used rather than a full-blown Preprocessor, directives inside skipped if blocks will still be found.

Returns

true if any directives were found.

ParseDirective()

static bool ParseDirective ( StringRef  S, ExpectedData *  ED, SourceManager &  SM, Preprocessor *  PP, SourceLocation  Pos, VerifyDiagnosticConsumer::DirectiveStatus &  Status, VerifyDiagnosticConsumer::MarkerTracker &  Markers  )

static

ParseDirective - Go through the comment and see if it indicates expected diagnostics.

If so, then put them in the appropriate directive list.

Returns true if any valid directives were found.
