void registerCheck(StringRef CheckName)
Registers the CheckType with the name Name.
Finds possible inefficient std::vector operations (e.g.
A collection of ClangTidyCheckFactory instances.
This check is to warn about the performance overhead arising from concatenating strings, using the operator+, instead of operator+=.
volatile int PerformanceModuleAnchorSource
Optimize calls to std::string::find() and friends when the needle passed is a single character string...
Finds calls to C math library functions with implicit float to double promotions. ...
A clang-tidy module groups a number of ClangTidyChecks and gives them a prefixed name.
void addCheckFactories(ClangTidyCheckFactories &CheckFactories) override
Implement this function in order to register all CheckFactories belonging to this module...
A check that flags value parameters of expensive to copy types that can safely be converted to const ...
A check that detects copied loop variables and suggests using const references.
