Member Function Documentation

diagnose()

template<typename... Args>

void P4::ErrorReporter::diagnose ( DiagnosticAction action, const char * diagnosticName, const char * format, const char * suffix, Args &&... args )

inline

The sink of all the diagnostic functions. Here the error gets printed or an exception thrown if the error count exceeds maxErrorCount.

error_reported()

bool P4::ErrorReporter::error_reported ( int err, Util::SourceInfo source )

inlineprotected

Check whether an error has already been reported, by keeping track of error type and source info. If the error has been reported, return true. Otherwise, insert add the error to the list of seen errors, and return false.

getDefaultInfoDiagnosticAction()

DiagnosticAction P4::ErrorReporter::getDefaultInfoDiagnosticAction ( )

inline

Returns

the default diagnostic action for calls to P4::info().

getDefaultWarningDiagnosticAction()

DiagnosticAction P4::ErrorReporter::getDefaultWarningDiagnosticAction ( )

inline

Returns

the default diagnostic action for calls to P4::warning().

getDiagnosticAction()

DiagnosticAction P4::ErrorReporter::getDiagnosticAction ( cstring diagnostic, DiagnosticAction defaultAction )

inline

Returns

the action to take for the given diagnostic, falling back to the default action if it wasn't overridden via the command line or a pragma.

getDiagnosticCount()

unsigned P4::ErrorReporter::getDiagnosticCount ( ) const

inline

Returns

the number of diagnostics (warnings and errors) encountered in the current CompileContext.

parser_error() [1/2]

template<typename... Args>

void P4::ErrorReporter::parser_error ( const Util::InputSources * sources, const char * fmt, Args &&... args )

inline

Reports an error specified by @fmt and @args at the current position in the input represented by @sources. This is necessary for the IR generator's C-based Bison parser, which doesn't have location information available.

parser_error() [2/2]

template<typename T>

void P4::ErrorReporter::parser_error ( const Util::SourceInfo & location, const T & message )

inline

Reports an error @message at @location. This allows us to use the position information provided by Bison.
