llvm::SmallString< 256U > Name
Base class for all clang-tidy checks.
Every ClangTidyCheck reports errors through a DiagnosticsEngine provided by this context.
Finds calls to C math library functions with implicit float to double promotions.
void check(const ast_matchers::MatchFinder::MatchResult &Result) override
ClangTidyChecks that register ASTMatchers should do the actual work in here.
void registerMatchers(ast_matchers::MatchFinder *Finder) override
Override this to register AST matchers with Finder.
void storeOptions(ClangTidyOptions::OptionMap &Opts) override
Should store all options supported by this check with their current values or default values for opti...
void registerPPCallbacks(const SourceManager &SM, Preprocessor *PP, Preprocessor *ModuleExpanderPP) override
Override this to register PPCallbacks in the preprocessor.
Produces fixes to insert specified includes to source files, if not yet present.
