Defines the Diagnostic-related interfaces.
Forward-declares and imports various common LLVM datatypes that clang wants to use unqualified.
static DiagnosticBuilder Diag(DiagnosticsEngine *Diags, const LangOptions &Features, FullSourceLoc TokLoc, const char *TokBegin, const char *TokRangeBegin, const char *TokRangeEnd, unsigned DiagID)
Produce a diagnostic highlighting some portion of a literal.
virtual void HandleDiagnostic(DiagnosticsEngine::Level DiagLevel, const Diagnostic &Info)
Handle this diagnostic, reporting it to the user or capturing it to a log as needed.
Definition: Diagnostic.cpp:560
A little helper class (which is basically a smart pointer that forwards info from DiagnosticsEngine) ...
Definition: Diagnostic.h:1571
const SourceLocation & getLocation() const
Definition: Diagnostic.h:1582
void FormatDiagnostic(SmallVectorImpl< char > &OutStr) const
Format this diagnostic into a string, substituting the formal arguments into the %0 slots.
Definition: Diagnostic.cpp:791
Concrete class used by the front-end to report problems and issues.
Definition: Diagnostic.h:192
DiagnosticBuilder Report(SourceLocation Loc, unsigned DiagID)
Issue the message to the client.
Definition: Diagnostic.h:1547
unsigned getCustomDiagID(Level L, const char(&FormatString)[N])
Return an ID for a diagnostic with the specified format string and level.
Definition: Diagnostic.h:873
The level of the diagnostic, after it has been through mapping.
Definition: Diagnostic.h:195
void HandleDiagnostic(DiagnosticsEngine::Level DiagLevel, const Diagnostic &Info) override
HandleDiagnostic - Store the errors, warnings, and notes that are reported.
void FlushDiagnostics(DiagnosticsEngine &Diags) const
FlushDiagnostics - Flush the buffered diagnostics to an given diagnostic engine.
