Detailed Description

Concrete class used by the front-end to report problems and issues.

This massages the diagnostics (e.g. handling things like "report warnings as errors" and passes them off to the DiagnosticConsumer for reporting to the user. DiagnosticsEngine is tied to one translation unit and one SourceManager.

◆ setDiagSuppressionMapping()

void DiagnosticsEngine::setDiagSuppressionMapping ( llvm::MemoryBuffer & Input)

Diagnostic suppression mappings can be used to suppress specific diagnostics in specific files.

Mapping file is expected to be a special case list with sections denoting diagnostic groups and src entries for globs to suppress. emit category can be used to disable suppression. The last glob that matches a filepath takes precedence. For example: [unused] src:clang/* src:clang/foo/*=emit src:clang/foo/bar/*

Such a mappings file suppress all diagnostics produced by -Wunused in all sources under clang/ directory apart from clang/foo/. Diagnostics under clang/foo/bar/ will also be suppressed. Note that the FilePath is matched against the globs as-is. These take presumed locations into account, and can still be overriden by clang-diagnostics pragmas.
