clang::tidy::performance Namespace Reference

Classes

class  FasterStringFindCheck
 Optimize calls to std::string::find() and friends when the needle passed is a single character string literal. More...
 
class  ForRangeCopyCheck
 A check that detects copied loop variables and suggests using const references. More...
 
class  ImplicitConversionInLoopCheck
 
class  InefficientAlgorithmCheck
 Warns on inefficient use of STL algorithms on associative containers. More...
 
class  InefficientStringConcatenationCheck
 This check is to warn about the performance overhead arising from concatenating strings, using the operator+, instead of operator+=. More...
 
class  InefficientVectorOperationCheck
 Finds possible inefficient std::vector operations (e.g. More...
 
class  MoveConstArgCheck
 Find casts of calculation results to bigger type. More...
 
class  MoveConstructorInitCheck
 The check flags user-defined move constructors that have a ctor-initializer initializing a member or base class through a copy constructor instead of a move constructor. More...
 
class  NoexceptMoveConstructorCheck
 The check flags user-defined move constructors and assignment operators not marked with noexcept or marked with noexcept(expr) where expr evaluates to false (but is not a false literal itself). More...
 
class  PerformanceModule
 
class  TypePromotionInMathFnCheck
 Finds calls to C math library functions with implicit float to double promotions. More...
 
class  UnnecessaryCopyInitialization
 
class  UnnecessaryValueParamCheck
 A check that flags value parameters of expensive to copy types that can safely be converted to const references. More...
