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. Longest 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.

When set to true, any fatal error reported is made an error.

This allows the client to specify that certain warnings are ignored.

Notes can never be mapped, errors can only be mapped to fatal, and WARNINGs and EXTENSIONs can be mapped arbitrarily.
